The Power of Listening

LESSONS LEARNED FROM 'CHEERS' TO PARENTHOOD AND BEYOND

By John Juhasz, Regional Sales Manager, Kraft Fluid Systems

» AFTER THE 11 O’clock evening news, they’d play syndicated re-runs of “Cheers”. It started with 3 or 4 guys making “a thing” out of watching “Cheers” regularly. Later it grew out of the standing-room-only space, in Doug and Kyle’s dorm room, and morphed into the TV room in the lobby.

Of course, Cheers eventually ended, and the spin-off “Frasier” picked up.

Dr. Frasier Crane’s famous tagline was “I’m Listening”.

I’ve spent some time “pulling wrenches” doing repairs on machinery. It sounds hard. A mechanic or technician can’t always just

start replacing parts. To diagnose it correctly, you must “Listen” to what the equipment is telling you. Is the pressure low? Is something hot? Is it making a weird noise? Did something slow down? Where is that oil coming from? Does anything you do make it better? Does anything you do make it worse?

I’m listening.

I’ve also spent some time designing and specifying systems. It sounds hard. You need to listen to the desired outcome. How much will this machine weigh empty? How much will it weigh loaded? How fast do you need it to go? Does the operator want this on a joystick button or a toggle switch? Is there a safety concern when THIS happens or THAT happen?

I’m listening.

For a while now, I’ve been involved in sales. It sounds hard. If you cut through the clutter and all the self-proclaimed gurus and experts, “Sales” is nothing but getting good at listening. Why does your customer prefer this arrangement? Would it have any drawback to make this change if you got this other feature? What’s your timeline for completing this project? How will you evaluate the prototype to make sure it’s fit for production? If I went over to engineering and asked Jeff the same question what would he say? If I went out to Service and asked Terry the same question?

I’m listening.

Somewhere along the way, in those last 30 years since “Cheers” re-runs at Ohio State, there are also four little “mini-me” clones of me running around. Parenting is another area

where there are a lot of “experts”. It sounds hard. Listening is important here too. (Some of them are not so fun.) Where does it hurt? Did you fall? Did your sister kick you? (and then the better stuff) … How did you make this neat painting of Stitch? Is that papier-mâché? What do you want Santa to bring you? What do you want to be when you grow up? Who’s your best friend at school? What teacher do you like the most? Do they still have Spelling Bees? Did Uncle Steve buy you guys lunch before he brought you back home?

I’m listening.

Our industry is always changing. That crystal ball can be cloudy. It sounds hard. We can probably listen to what it’s telling us. Is there more emphasis on electrification? Is power density always going to be a thing? How do we pass on what we know? What should we pass on and what SHOULDN’T we? Who are we passing it on TO? What do THEY want to know? What do they NEED to know? What will THEY teach US? What’s going to look different in 30 years? What’s going to look the same in 30 years? What’s going to BE the same but LOOK different in 30 years?

In case you’re wondering, they did a reboot of “Frasier” this last fall, 20 years after the original run of “Frasier” ended and 30 years after “Cheers” ended.

Maybe some things don’t change so much after all. What do you think?

I’m listening.

The problem with the machine overheating seemed to be caused by the relief not unloading when the solenoid operated valve is de-energized during the idle cycle. This causes the full pump flow to return to tank at 13.8 MPa (2000 PSI) pressure drop across the valve’s poppet. This was adding approximately 7° C (14 °F) temperature increase in the flow going back to the tank. The cooler was not designed for this amount of heat being generated.

Examining the directional valve and main relief poppet showed no signs of malfunctioning or sticking. What would you do next?

Considerations for Using Sensors to Control Cylinders

By Perry Hudson, Market Manager, Pepperl+Fuchs Inc.

The use of magnetic or inductive sensing devices to indicate cylinder position is nothing new. These proven methods each have their strengths, which we will discuss in this article. There are several factors to consider including environmental conditions, potential for interference, and cylinder integrity.

When examining which technology to use for cylinder position monitoring, a typical starting point is what the cylinder manufacturer already offers as a mounting port for a sensor and what is installed as a potential sensing target. It is common practice to have a dissimilar metal target on the inside of the shaft. This can provide a target for either a magnetic or inductive approach. In some cases, manufacturers even install a magnetic target on the shaft inside the housing, this is however an older approach. Regardless of whether it is a dissimilar metal or magnet; you can use the sensors in different mounting methods.

Magnetic sensors locate the target through the cylinder housing; therefore, they are typically strapped to the outer housing. This makes them popular because they are easier to install. A possible shortcoming of this approach may be that they are not as accurate in determining position as a sensor that is built into the housing. Another potential problem with magnetic sensors is that they can magnetize the housing they are attached to over time. This can lead to a position deviation, which can increase with temperature variations. However, these are only possibilities, as this technology is tried and tested and has been in use for over forty years.

Inductive sensors are installed in the cylinder at the end of travel. Most cylinder manufacturers pre-drill sensor ports today, so it is simply a case of understanding the required process dimensions. This approach has also proven to be very effective and accurate. Possible disadvantages of using inductive sensors can be that there are no current mounting ports. Drilling holes in cylinders can cause major problems, affect the warranty, and incur additional costs. There may also be problems with the required installation location of the sensor or the operating pressures. All of these concerns need to be considered, but again, this technology is proven and has been used for over forty years. A third method is less invasive; the use of linear potentiometers or linear variable differential transformers (LVDTs). These are precise, proven, and sometimes the most inexpensive approach. These linear potentiometers are made up of cylinders with transducer rods having the same travel as the cylinders being monitored. They are mounted on the outside of the cylinder. The transducer rod is attached to the cylinder rod, tracking its movement. These devices monitor the position of the cylinder rods by measuring the change in resistance as the transducer rods change position. They are very effective, but also susceptible to damage to the exposed transducer rod. They are the oldest of the sensor technologies and have been used in the paper and textile industries for over eighty years.

The latest method is also non-invasive. It combines the precision and repeatability of an inductive sensor with the simple mounting of an LVDT. Linear inductive sensors came onto the market around twenty-five years ago. Unlike the aforementioned devices, only a target is mounted to the cylinder rod. The linear sensor is mounted next to the cylinder near the target. As the cylinder shaft travels over a row of sensor coils, it provides position feedback. As a rule, it can also provide end of travel or preset positions. Although this may not be the solution for everyone, this approach is becoming increasingly popular.

Once the sensing method has been selected, a decision must be made as to what type of control system is desired. While programmable logic controllers (PLCs) are the most common in industrial control, microcontrollers (MCUs) or dedicated process controllers are not uncommon in fluid control. Each of these devices can process sensor data and make decisions based on predefined logic. To choose the right sensing method, you need to know what is required in terms of discrete or analog inputs.

You now have determined the preferred type of position sensing and the type of signal processing that will be used to monitor and control the system. From here, a general understanding of the available sensor outputs will help finalize the application design. For a magnetic sensor, a mechanical Reed switch or dry contact is typically used. The two-wire circuit is energized, and when the magnet is applied, it closes the contact, creating a complete circuit.

An inductive sensor is a solid-state device that provides a discrete transistor output. This can be in the form of a voltage/current change for a two-wire sensor or a separate output signal for a three-wire sensor. Discrete two-wire sensors are older in design and have a simpler wiring scheme, but they have a constant voltage and leakage current flowing through them. While a single sensor in a no-load state will not generate enough leakage to send a false input to a typical modern processor, care should be taken to avoid connecting several of these sensors in series as leakage levels can multiply. For inductive three-wire sensors, this problem is avoided by the addition of a third output wire.

Another consideration with inductive sensors is the fact that their processing circuits are built with bipolar junction transistors for amplification and switching. These transistors come in two main types: NPN (negative-positive-negative) and PNP (positive-negative-positive). When choosing the right sensor for your control system, it is important to understand the differences in the application. A good way to understand is to look at the current flows for both. In an NPN transistor, most of the charge carriers are electrons, with current flowing to the positive side. In a PNP transistor, most of the charge carriers are positive and current flows to the negative side. Your control system will indicate which type of signal it requires as an input, so always confirm this.

We have now looked at sensing methods and outputs. We should discuss the typical control logic of a standard cylinder circuit. In most cases, sensors are used to indicate the end-of-stroke operation of the cylinder. This tells the system and the operator whether the cylinder is fully extended or fully retracted. In some systems, an analog signal is used to indicate a variable extended position, but the basic method of operation remains the same. The process begins with a start signal provided by either a sensing point, a manual switch, or even a PLC signal. Once the signal is received at the control device, either a PLC or a dedicated controller, a sequence of operations begins. These operations activate a directional control valve that controls the direction of air or liquid. The control valve determines whether the cylinder extends or retracts.

In response to this start signal, the control element sends a signal to the directional control valve of the cylinder, causing the cylinder rod to move to the desired position.

As soon as the cylinder rod is in motion, the sensors detect the position of the rod and

give the control element feedback about the full extension or retraction. This "feedback loop" determines the exact positioning of the control element and enables decisions to be made as to whether it should continue, stop, or change direction. The control element then acknowledges the end of the cycle and generates a stop signal.

This typical control circuit offers the option of adding safety features such as emergency stops into the circuit. Now reset circuits and redundant circuits may be added based on the

functional safety requirements of the application. Through the use of visual indicators, such as lighting or an HMI, system maintenance and training can be integrated. The use of “intelligent sensors”, provides information that is useful for predictive maintenance. Such a well-tested control design is far from obsolete. New advances in sensor and control technology enable reliable, precise control of cylinders with many mounting options. It all starts with the question: What do you want to do? •

In the unique world of mobile and industrial hydraulics we often find ourselves needing to synchronize torque and speed when using multiple motors. This sounds like a simple idea, and in a perfect world there would be a simple solution. However, we all know that very few things in hydraulics are as simple as they appear, fortunately, with the use of 1:1 ratio counterbalances, torque and speed synchronization can be easily accomplished.

One of the earliest fundamentals we learn as we enter the world of hydraulics is the difference between parallel and series circuits. Once we have identified an application requiring speed synchronization of motors the first idea that pops in our minds is a series circuit. Simple right… Problem solved?

Fortunately, around the same time we learned about series and parallel circuits, we also learned about efficiencies. Hydraulic motors are great at transmitting large amounts of power in a small package, but nothing is perfect in hydraulics and there are mechanical and volumetric inefficiencies to consider. As hydraulic designers, we must account for these inefficiencies. Electronic and proportional technologies are rapidly advancing, and we often use them for precise speed and/or force control. By using speed sensors, we could electronically close-the-loop and achieve precise

control. This sounds great at first, but these solutions are typically expensive and require expertise to apply.

So how can we achieve speed synchronization in applications that are sensitive to price pressures? Let’s consider an example of a four-wheel machine that is propelled via two hydraulic motors. We would like both motors to turn at the same RPM with the same amount of torque. Once again, this sounds simply accomplished by using two motors in series with some means of controlling speed. The flow out of the first motor will be supplied to the second motor and they should have identical RPMs, correct? Unfortunately, due to ever present inefficiencies, this solution will have limited performance. The second motor will not be supplied the same amount of flow as the first due to volumetric losses internally through a case drain. Due to the flow loses, we would expect the second motor to turn slower than the first.

Now imagine we have 100% volumetrically efficient motors. If we have the same amount of flow entering motor number two as motor number one, should we not expect the same torque out of both motors? Unfortunately, motors are hydromechanical devices and even with advances in materials and machining technologies, having two motors with identical mechanical efficiencies is highly unlikely, if

not impossible. Therefore, we must assume that the pressure drop required across each motor just to get it to turn without a load will be different. In a perfect world the pressure drop across each motor will be half of the pressure drop supplied to the first motor. In reality this is not the case.

TM1lbf-ft=p1-p2VD [psi∙cm3rev]1235

TM2lbf-ft=p2-p3VD[psi∙cm3rev]1235

The torque output form M1 and M2 are not equal since the flow into M2 is less than the flow into M1 because of losses like the case drain. Therefore, in order to have equal torque on both motors, some compensation for losses must be considered. Similar to hydraulic fan drives, another approach to motor speed control is to use pressure control instead of flow control. If we again imagine a 100% volumetric efficient motor and we were somehow able to get identical mechanical efficiencies, we should expect identical torque and speed if each motor is supplied the same flow. By using 1:1 pilot ratio counterbalance valves we can supply the same torque to each motor.

The circuit above shows two bi-directional motors in series with the addition of a 4-port vented 1:1 pilot ratio counterbalance valve with a mechanical setting of 400 psi. The counterbalance is used as a relief or compensator between P1 and P2. Port 4 is connected to port 2 which causes downstream pressure to be additive to the setting by a factor of two (1+Pilot Ratio) * Back Pressure. With a low setting of the counterbalance, the pressure at port 1 is

continued on page 12

Figure 3 Torque division between two motors in series using 1:1 pilot ratio counterbalance valve to maintain equal torque division

continued from page 11

2 times greater than the pressure on port 2. The counterbalance will open when pressure between the two motors falls below the pressure upstream of the first motor, ensuring equal pressures and equal torques from each motor. The checks in the circuit prevent a short circuit back to tank and they also allow for a single counterbalance to be used for bi-directional motors in series.

To further explain how this circuit performs, let’s assume both motors have a 1,000 psi induced load. When the directional control valve is shifted and flow is directed to port A and Motor 1, pressure will build to overcome the induced loads of both motors. If our motors were 100% efficient, we would expect to see 2,000 psi on G1 and 1,000 psi on G2, with 1,000 psi ΔP across each motor, creating identical torques and speeds. As reminded earlier, motors are not 100% efficient, therefore, we will closely examine the benefits of adding the 1:1 counterbalance valve. The scenarios below assume the system relief or pump compensators are set higher than the maximum achievable effective setting, and a return line pressure of 200 psi.

In Figure 4, as both motors begin to rotate, Motor 2’s 1,000 psi load

However, in this case we have a vented counterbalance valve and pressure at port 4 has the same effect to the setting as backpressure on a non-vented counterbalance. We are using this to the modulate flow as the loads change by dynamically changing the effective setting of the counterbalance to maintain the p1 and p2 within a small difference in pressure. Starting with a 400 psi mechanical setting, we would expect the counterbalance to have an effective setting of 2,800 psi = (400 psi setting + ((1:1 +1)*1,200)). The counterbalance will remain closed as long as the pressure at G1 is below 2,800 psi. If both motors are rotating at the same rpm and torque with all forces in equilibrium, we would expect the counterbalance to remain closed with 2200 psi at the inlet of the first motor, 1200 psi at the inlet of the second motor and 1,000 psi pressure drop across each.

Considering volumetric losses due to motor leakage, the torque at motor B will be less than the torque of motor A because it has less flow available. Torque is a function of pressure, flow and RPM, and the counterbalance helps maintain torque and rpm by controlling pressure and flow through modulating makeup flow to the second motor in the series. This helps keep the torque nearly equal on both motors.

Tlb-ft=p[psi]∙5252N[rpm]

Php=p[psi]∙Q[gpm]1714

T[lb-ft]=p[psi]∙Q[gpm]1714N[rpm]∙5252

Since the torque available from motor 2 B is less, the torque requirement on Motor 1A and the pressure at G1 will increase. Simultaneously, the pressure at G2 will decrease due to less pressure drop at the lower flow, causing the effective setting of the counterbalance to lower. Once the effective setting is equal to G1, flow will be directed to Motor 2 through the counterbalance valve. The counterbalance will modulate as the effective setting varies due to changes in speed or loads, providing additional flow to Motor 2 while ensuring that G1 is two times greater than G2. By maintaining the same pressure drop across each motor, both motors achieve the same torque and RPM.

Application of hydraulic motors in series is useful when designing equipment but the hydraulic circuit must be carefully considered. Without some means of ensuring that torque is shared between motors, one motor could be overloaded and cause premature failure. The use of a vented counterbalance valve in a novel way provides a means of torque division to load the motors nearly equally in series. •

UNDERSTANDING BREAK-AWAY, RUNNING, & STARTING TORQUE

Amotor has a certain amount of mass that must be accelerated to the speed required to do the work. The object being moved also has some mass. The force to accelerate this mass is referred to as starting torque. There also may be some other resistance that must be overcome. This combination of starting torque and any additional restriction is referred to as break-away torque. For example, an auger moving feed to cattle must overcome its own mass and also the natural stiction of the feed. Once the motor gets up to speed, the resistance drops, and a lower torque is required to keep the load moving. This is running torque.

The stall torque is the maximum motor force, based on the pressure available and the displacement of the motor. It is the resistive force that will cause the motor to stop turning. The stall torque must be higher than the break-away torque but must be limited for the safe operation of the equipment and/or the limitations of the motor.

The geometry of most hydraulic motors is such that there are variations in torque as the motor rotates. This is called torque ripple. A 9 piston, high speed/low torque, axial piston motor will have 9 pulses of energy for every revolution. At 1,550 rpm, the pulses would be at 232 Hz and may have very little impact. A 6 lobe, low speed/high torque motor at 50 rpm will have a torque ripple of 5 Hz. At this low rpm, this torque ripple sometimes referred to as cogging, may influence process control.

When specifying a motor, it is important to include the maximum necessary starting torque as well as the running torque. If only the running torque is calculated, the motor may stall or be very slow in reaching the proper working velocity. When specifying a motor, it is important to include the maximum necessary break away torque as well as the running torque. If only the running torque is calculated, the motor may stall or be very slow in reaching the proper working speed.

For example, given an auger with a running torque of 400 Nm (3,540 lb-in) at 1,200 rpm, and an available pressure of 21 MPa (3,045 psi), a hydraulic motor must be chosen that can accelerate its own mass as well as overcome the stiction of the of the product being transferred. The manufacturer's specifications say the motor will require an additional 10% pressure for start-up. The product stiction will require an additional 15% torque.

The required breakaway torque for this application is arrived at by multiplying the running torque required by the manufacturer’s data stating that 10% additional torque is necessary to overcome the inertia and mechanical friction internal to the motor which is the starting torque. This starting torque value of the motor is then multiplied by the additional amount of torque that is required to overcome the feed auger at rest which was given at 15%.

» HERE IS THE SOLUTION TO FIGURE IT OUT ON PAGE 05

One major problem when troubleshooting logic slip-in valves is that there are exceedingly small orifices found in various areas. Orifice “A” controls the closing speed of the main poppet, while the “C” orifice controls how quickly the main poppet opens. If the “C” orifice, as small as 0.1 mm (0.004 in), is blocked by contamination, the relief will not open as designed causing the overheating problem.

VACUUM CLAMPING FOR DIVERSE APPLICATIONS

By Dane Spivak, President, Davasol Incorporated

have authored numerous articles on vacuum pick and place, a widely used application in fluid power circles for vacuum components. However, another common application for these products is material hold-down or vacuum clamping. Industries like sign manufacturing, glass production, fiberglass fabrication, aerospace CNC machining, and automotive trim finishing utilize vacuum hold-down. This article explores the basic methodology for achieving a secure, safe, and energy-efficient system for these diverse applications, emphasizing the need for rigid hold-down, ease of product capture, release, and cost-effectiveness.

CNC routers, as shown in Fig 1, often use a porous vacuum bed made from porous MDF (medium-density fiberboard) for holding workpieces, like cabinet manufacturing. A large flow vacuum pump, typically an oil-free sliding vane pump or high-performance regenerative blower, connects to a chamber beneath the MDF sheet, creating a vacuum to secure the workpiece. The greater the surface coverage, the higher the vacuum level and holding force. As depicted in Fig 2. to minimize leakage, the uncovered MDF area may be covered with a thin plastic sheet.

The holding force is determined by the vacuum level achieved. High flow pumps are employed, as seen in CNC routers, where the theoretical holding force per square inch is 64N at 100% vacuum. However, lower vacuum levels may reduce the holding force, necessitating additional measures like covering the open MDF area with plastic sheeting.

For applications involving parts with higher cutting forces, such as aluminum machining or marble and granite countertop manufacturing, vacuum "pods" (Fig 3) are commonly used. The parts of the pods are shown in this illustration. 1, vacuum port for workpiece, 2, vacuum port for machine table, 3, high lateral force grip pad (to prevent work piece of machine table movement

in side load conditions from cutting tools) and finally 4, which is a vacuum seal to create the vacuum.

These pods, connected to a vacuum pump or venturi, are used in groups as shown in Fig 4. In cases of thin sheets or non-flat profiles, custom vacuum beds or tools (Fig 5 and 6) may be required.

The vacuum pod, illustrated in Fig 3, boasts a substantial holding force. In this specific example, the model measures approximately 200 mm (8 inches) square, resulting in a holding force of around 3200 N (719 lbs.) at 24” Hg (152Torr). Combining two of these units would naturally double the holding force to 6400N and so forth. It's essential to note that machine coolant on the gripping surface could pose challenges by creating a liquid film, significantly impacting side load resistance. The cusp design of the vacuum pods, depicted in Fig 3.1, effectively mitigates this risk, facilitating the easy dispersal of trapped coolant at each node.

End users often employ continuous "ON" vacuum pumps or venturis for long production cycles. However, for non-porous products like flat aluminum billets, turning off the vacuum once a safe level is achieved offers substantial energy savings. Fig 7 illustrates a multi-stage air-powered vacuum generator with an energy savings "kit" for efficient air control. This cycles on and off as vacuum is required or as the level falls due to a small leak. This can have considerable energy costs savings.

In summary, the landscape of vacuum clamping applications is diverse, with efficiency, user-friendliness, and operational expenses emerging as shared priorities. Through a thoughtful consideration of vacuum tool performance and the adoption of energy-saving practices, users can make well-informed decisions for optimal solutions. The provided examples shed light on various approaches to address the principles of vacuum clamping applications. •

Small Burrs Create SignificantProblems

Think about "mission critical manifolds" in high productivity, no downtime world.

Windmills and especially offshore installations are excellent examples of costly component failure. Hydraulic elevator platforms are also good examples of critical systems that can be life-threatening in case of failure. But these risks also pertain to various industries or any large machinery.

Leave nothing to chance and use thermal deburring (TEM) to get rid of burrs and particles to ensure that manifolds and valves will deliver without any issues.

By the way, TEM stands for Thermal Energy Method.

After reading that article, you will understand how thermal deburring works, where this technology works best, the pros and cons, and how it compares to other deburring methods.

TEM accommodates materials like cast iron, steel, stainless steel, zinc, aluminum, brass, and some thermoplastics.

Thermal Deburring can take away burrs like a breeze. That breeze is a super heat wave, reaching 3,300°C (6,000°F) in just a few milliseconds.

Methane, a readily available fuel with good energy content by volume, is the most common fuel gas used for thermal deburring. Methane may be supplied technically pure in bottles or through the Natural Gas networks where available.

Hydrogen is also a suitable fuel gas for the TEM process, although less frequently used. Higher volumes are required compared to Methane, incurring higher costs. Hydrogen produces water as the main by-product and can be considered a more environmentally friendly option.

The first benefit of that technology is speed.

Because the burrs or flashings are much smaller than the component, they reach their auto-ignition point instantly. The burrs oxidize in the oxygen-rich chamber without any harmful impact on the element.

Compared to manual deburring, you have the insurance that the deburring operation will run without further inspection. That's reliability. In addition, you remove the burden of finding skilled labor by relying on a machine. You are a perfectionist; the machine can be automatically loaded and unloaded.

The third benefit of that technology is low cost per part.

What does Burrs mean?

Nobody wants burrs. But even with a tremendous effort in design, process planning, and manufacturing, it is hard to ensure that finished parts are completely free from burrs consistently.

The second benefit of that technology is integrity.

The burr? It's vaporized, gone!

Burrs can ruin the design integrity of the part, require additional processes to fix it, cause safety hazards, and result in a malfunction of the product. That generates additional cost, re-manufacturing, warranty, service, and recall, saying nothing of collateral damage to the company's image. No choice. You need to

workpiece material. The sharpness of the burr may be the most essential criterion for safety concerns.

Burrs Impact.

Today, fluid power is at the heart of many critical areas. It's present in some of the most challenging tasks - control, maneuver, lift, dig, brake, steer, adjust, and many more. At the same time, the demand for higher power, faster response, finer control, and compact sizes has driven modern-day fluid power toward higher operating pressures, intricate designs, and compact dimensions. h

applied in the fluid power industry. Steel, cast iron, and aluminum are suitable materials for TEM. Thanks to the existing large chamber, largesize manifolds can be processed.

The Thermal Energy Method (TEM) of deburring utilizes energy generated in the combustion of gases to oxidize burrs. This method differentiates burrs from the component by the ratio between surface area and mass. Burrs, which are high in this ratio, absorb most of the heat and get vaporized in oxidation.

TEM produces intense heat energy by igniting a pressurized mixture of combustible gas and oxygen within a sealed, specially controlled chamber. Due to the sudden release of heat energy, a high-temperature blast up to 3,300°C (6,000°F) is generated for a few milliseconds. As a result, burrs and flashes catch fire, burn, and vaporize till heat gets dissipated into the body of the workpiece. In the process, the workpiece also gets heated but to such a limited extent that there is no change in its metallurgical properties.

TEM is known to deburr components in and out in one go. Deburring of multiple parts is a possibility as gas flows around them. The cycle time of the process, excluding component loading and unloading, is typically less than a minute, making this technology a very productive method.

In TEM, the volume of gas injected into the chamber, the thickness of the burrs, the heat transfer rate of the processed material, and the ratio of fuel to oxygen define the amount of removed burr.

Process steps

1 The chamber is filled with a pressurized mixture of gases.

Loading of the components into the TEM chamber. The chamber is closed.

2 Gas is ignited.

3 Burrs are oxidized, and the component deburred.

4 The chamber is vented to de-pressurize.

5 The chamber opens, and the component is unloaded.

6 The TEM-qualified components.

• Valve bodies – with many intersecting holes, grooves, threads, and inaccessible areas, these components are a deburring nightmare. TEM is ideally suited for valve bodies. Efficient deburring makes assembly easy, spool movements free, and the entire system reliable.

• Manifolds – with challenges like valve bodies, manifolds are well suited to TEM deburring.

• Spools – precision grooves and intricate holes & notches make spools too intricate to be manually deburred. Ineffective deburring can cause inappropriate system functioning and even jamming.

• Pump and hydraulics motor elements –high-pressure pumps and hydraulics motors, characterized by minimal clearances between moving parts, are susceptible to failures requiring practical components deburring.

• Cylinder components – cylinder porting blocks and end caps are standard in TEM deburring

• Hydraulic fittings – often ignored, these are a common source of burrs. Once dislodged, burrs go to other critical areas in the circuit, causing havoc.

No worries, this process by-product will be removed during a cleaning operation. Chemical market leaders in cleaning and degreasing offer a range of post-cleaning products designed to address the different materials.

These products are utilized in post-treatment stations typically used for cleaning and passivation. The equipment starts with straightforward dunking stations and goes up to multiple automated stations with advanced cleaning features like ultrasonic.

TEM provides superior and affordable deburring for the real world.

Thermal Deburring not only delivers on the deburring quality, the productivity, and the cost per part but also solves some of today's industry challenges like new intricate designs prohibiting manual deburring, health requirements preventing people from repeating the same motion too many times, lack of interest from workers for the deburring jobs, shortage of labor, cost of labor in some area of the world.

How do I gain access to the TEM Technology?

There are manufacturing companies on the market offering TEM equipment. Alternatively, suppose you do not have a volume justifying an investment. In that case, you can access that technology through a contract service offering.

The TEM equipment comes in different sizes; their naming is sometimes related to

Secondary

their clamping force and the chamber size. In most cases, the chamber is round, open at the bottom, and has a top featuring a bell shape. Chambers come in various diameters and heights. Recently, we have noticed an inflation in the chamber size to accommodate either larger manifolds or long shafts, the latest driving the appearance of the chamber with a one-meter length or more. Some manufacturers are using a cubic design as an alternative. TEM machines seem pricey, but their life spans for decades, especially when not running at high pressure, and their service cost is low. In addition, their efficiency delivers the lowest cost per part.

Wrap-Up: Some TEM highlights.

Deburring effectiveness. TEM Eliminate burrs, flashings, and loose particles, regardless of their location on – or inside – the component.

Process efficiency. Unlike traditional mechanical and abrasive methods, no media can become trapped in internal areas or contaminate the surface.

Ease of use. TEM is not a line-of-sight process requiring targeted media programming compared to waterjet. With TEM, the gas envelops every area of the component simultaneously.

Blockage elimination. Compared to water jet, mechanical and abrasive methods, TEM is a non-contact process; therefore, burrs and flashings cannot be folded or pushed onto the component.

Abrasion elimination. Compared to manual and mechanical methods, TEM does not generate secondary burrs, and there is no risk of scratching critical areas. Machining simplicity. Only simple baskets and workpiece-holding fixtures are required.

Extremely high production rates. Up to hundreds of parts in a 30- to 60-second cycle time is typical, and 24/7 operations are achievable.

Cost-effectiveness. TEM processing cost is less than a fraction of a cent for gas and electricity usage per component, resulting in the lowest operating costs in the finishing industry.

Quality and repeatability. Superior process stability and reasonable process control ensure precision, constant quality, and the highest repeatability.

Uniform results. Our tooling assures uniform energy distribution and protects surfaces while undergoing processing.

Customized tooling. Plate and pin fixtures are corrosion-resistant and custom-designed to suit specific applications.

Ease of automation. TEM tooling provides easy loading and unloading of components and maintenance of workpiece orientation.

TEM ensures enhanced component performance. Many customers report a reduction in component performance failures and warranty claims, leading to higher customer satisfaction. •
