>> Traxon smart machining system World leaders in oil level control systems in industrial compressor units are Traxon Industries in Bunbury WA. In compressor units used primarily in refrigeration systems in supermarkets, refrigerant oils can be Hamish Todd (JH), Wayne Cattach (CEO) transient around the and Brad Eacott piping system for long distances. Maintaining consistent oil levels is vital to the performance and operation of the compressors.

Integrated into the system, the Integrex 100 is a multitasking lathe that performs “done in one” machining of components. The result is a system which automatically produces regulator casings to exacting quality and environmental standards.

Traxon exports over 80% of its product overseas and CEO, Wayne Cattach and machinist Brad Eacott worked closely with John Hart engineers to ensure the system meets their requirements for flexibility and accuracy to match market demand for their product.

To ensure the system is maintained properly at the specified levels, Traxon developed and patented a floatation device.

The revolutionary regulator is able to monitor oil levels in the individual compressors and maintain correct volumes of oils at all times and through a wide variety of system conditions.

Traxon’s regulator is contained in an aluminium casing which is machined on a Mazak Integrex 100 with GL 100 robot together with a John Hart designed and built work conveyor, washer and drying system. The whole system is controlled by a PLC.

>> Oilpath achieves high flexibility Oilpath Pty Ltd which is situated in Adelaide, is the only designer and manufacturer of hydraulic control valves in Australia. Oilpath’s strength is their ability to provide standard valves with a wide range of standard and specialised options, fitted both in the factory and in the field by their network of distributors.

Oilpath now exports between 15% and 25% of their production into a variety of industries including transportation, construction, agricultural and industrial equipment.

reduce the stock build up, which was becoming a problem due to minimum batch sizes required in the current process.

From this they realised that a whole new approach was needed in their production process. They needed to be able to reduce their standard deliveries from four days down to a more competitive one day. They also knew they had to

customer demand.

To achieve these goals, Oilpath needed the latest and most flexible technology available. They needed a system which could recognise any of the company’s 13 valve castings and produce any of the 347 possible part numbers automatically, including specials, from a master machining schedule.

Having looked at the options, the solution was found in the Mazak Variaxis 630 with a 12 pallet Originally Oilpath sat down with Palletech system. The Variaxis 630 the engineers from John Hart to has five simultaneous axis capability, look at a project to machine valve 120 tools, 22kW main spindle, bodies on one machine.

This combination of John Hart production experience and Mazak technology in partnership with Oilpath has resulted in a world class production system.

>> UN series – machining centres for mass production.

Unique, Ultra Narrow machines for mass production applications, the UN Series horizontal and vertical models have created an enormous impact since their recent release. Unlike competitors’ narrow machines which have very small work envelopes, the Mazak UN machines have work capacities similar to conventional 400mm square pallet machines – all in a width of 695mm for the UNV and 990mm for the UNH machines.

The UN Series machines are not only compact with a small imprint, but they readily lend themselves to unmanned operation with easy adaptation to accept work holding systems and robots and offer very convenient maintenance access.

The new range has been a great hit with the automotive industry sub contractors where quality, accuracy, price and floor space demands are critical.

>> OH&S compliance – new machines For some time it has been the responsibility of end users of all machinery, including machine tools to ensure that their equipment satisfies and complies with the various Australian Standards and State Regulations and Acts. Over the last 2 to 3 years the state work safety authorities have been more stringent and vigilant in their enforcing of the various regulations. John Hart has always tried to ensure that the machines that we sell are of the highest safety standards required at the time.

However, many end users of machinery will not be aware of their new obligations to comply with the Radiocommunications (Electromagnetic Compatibility) Standard 2001 issued by the Australian Communications Authority. This standard relates to the Radiocommunications Act of 1992 and is a part of a long standing international effort to reduce electromagnetic radiation emissions from all sources.

What does this mean to a John Hart imports all user of industrial equipment machines and robots such as machine tools? with CE marking It means that any machine imported into Australia from January 2004 (there was a 2 year amnesty) must comply with this standard. It is the legal responsibility of the end user to ensure that equipment installed into their premises from this year fully complies. If it does not comply it is the end user’s responsibility to modify the equipment to comply – which would be very expensive to achieve on an existing non compliant machine.

John Hart customers can be assured that all new equipment imported from January 2004 complies with this standard.

John Hart imports all machines and robots with CE marking to satisfy all Australian safety and EMC standards.

Customers should ensure that when they are considering offers for new equipment that all suppliers are offering equipment that: • Complies with all Australian Standards and Regulations, preferably by being CE marked to comply with the following EC directives as applicable: Safety of Machinery – ISO 12100, ISO 14120, IEC 60204-1, EN 12415/12417/12478, EN 292-1/292-2/418/775 Electromagnetic Compatibility – IEC 61000-6-2/ 61000-6-4, CISPR 11/EN 55011 Low Voltage Equipment – IEC 60204-1/60034/60947 (Be sure that the "CE mark" does not only refer to something obscure like the colour of the paint!)

• Is supplied with a signed manufacturer’s "Declaration of Conformity" stating the various standards and directives that the machine is built to, the machine build date, serial number and technical file number.

• Is supplied with a signed Hazard Identification, Risk Assessment and Control Evaluation document from the machine supplier or manufacturer.

Only then can you rest assured that you have met your legal obligations and your machine is safe to install and operate and when an inspector knocks on your door you have the documented evidence to prove compliance.

>> Renard Tooling achieves “done in one” Renard Tooling Technics has been one of Ballarat’s best known toolmakers for over twenty years, establishing itself as a specialist to the automotive, FMCG, steel, advanced rubber and plastic moulding industries since 1982.

With a solid reputation for quality, Renard wanted to stay focused on remaining ahead of the market by identifying advanced technologies they could utilise to drive new business opportunities.

users, Renard gained greater confidence in their final machine selection.

They chose the Mazak Integrex 200-MkIII because of its advanced features, proven track record, high quality manufacture, and user friendly software which combined to allow them to hit the ground running. All this was backed by skilled engineers from the John Hart Service Team.

Renard visited Mazak’s headquarters and central The result since Scott Pfeiffer and Wayne Howden (machine operator) with the IG200 manufacturing facility in Nagoya, installation has been Japan and it was here they were able to see first hand the faster turnaround on jobs due to “done in one” processing, most advanced machine tools.

>> Nordon chooses a multi-tasking solution for success Nordon Hydraulics was founded by Norm Johnson in October, 1972 in Brisbane, Queensland. Guided by a passion to provide quality, service and satisfaction to their customers, the business first started out servicing hydraulic cylinder equipment. They worked on everything from a barber’s chair to excavator cylinders all the way through to mass produced cylinders for agriculture.

Through this exposure to so many different designs of infield hydraulic cylinders, the company moved to develop their own range of hydraulic cylinders.

After years of design and testing they were able to release the “Standard Range” of hydraulic cylinders.

This change in direction was a significant event in the history of the company as it set the foundation for their expansion into manufacturing their own products.

Recently with business expanding, Nordon looked to their long term partners, John Hart to come up with the best solution to meet their production needs.

Mark Geltch (Production Manager) and Norm Johnson (Director).

After discussions about the process and careful consideration of the technology available, the new Mazak Quick Turn Nexus 200MS with a second spindle, milling on the turret, parts catcher and bar feeder was chosen.

The Mazak has a 200mm chuck, a 26kW 5,000rpm spindle, a 4,500rpm rotary tool spindle and a maximum machining diameter of 380mm.

The Mazak system is a highly efficient, fully automated multi-tasking solution which allows unmanned operation and complete part processing in a “done in one” set up.

The result has been a 30% increase in productivity over previous methods.

Commenting on their third Mazak machine Parts made on the Mazak Today Nordon Hydraulics manufactures solution, Norm identified the need to hydraulic cylinders for a wide variety of increase production, technology offered by Mazak and the industries including the agricultural, earthmoving, transport experience and support offered from John Hart as the main and machinery industries. reasons for going with the John Hart / Mazak solution.

>> Introducing the HyperGear 510 The recent unveiling of Mazak’s latest 2D laser processing machine, the HyperGear 510 has caused quite a stir with metal fabricators throughout the world. The new HyperGear 510 uses custom linear motors to deliver rapid traverse rates of 120m/min at a staggering 3g acceleration on all axes.

The increased use of sensors, refined programming, readahead controls, flying optics design and new algorithms make the HyperGear up to 20-30% more productive than other machines on the market.

The HyperGear 510 flying optics design maintains a fixed beam length utilising a specially designed U-axis. This increases cutting accuracy by maintaining uniform laser power across the full table range.

Machine software automatically calculates the laser's optimum cutting speed and acceleration for each contour of a component. The nanosecond PREview 640 CNC control automatically determines the best method of piercing the entire sheet so that no area on the sheet becomes too hot, preserving cut quality.

With many customers throughout Australia having difficulty finding skilled operators, the HyperGear 510 now allows one operator with a lower level of training to be able to operate several machines simultaneously.

The new HyperGear 510 incorporates many "world firsts", including: • The first automatic torch changer and nozzle changer systems • The new PREview 640 CNC control • The first hyperlinear drive design • The first laser to diagnose and repair cutting-related problems in process • The first laser to automatically notify operators in advance of required maintenance

To ensure maximum productivity during work-piece processing, sensors detect when any of four automatically interchangeable torches require changing or may need a new nozzle, then the machine replaces the torch and/or nozzle without operator intervention.

>> Technology brings success for Sharp Tooling About two years ago Sharp Tooling, a general engineering and special cutting tool manufacturer in Sydney sat down with the engineers at John Hart to look at ways of increasing their production capability. The result was the addition of a Mazak Integrex 200Y multi-tasking machine to their factory. Managing Director Albert Carrion made the choice because he was confident that the new multitasking technology would take his company into the future.

occasionally one offs which explodes the myth that large production runs are required for multi-tasking machines.

The combining of turning and milling in the Integrex has reduced compound errors inherent in multiple set-ups, which has increased part quality. The user-friendly Mazatrol Fusion 640MT CNC conversational controller is easy to program, even by inexperienced operators. Stock in process has been reduced, overall machine programming time has been reduced, machine setups have been reduced, delivery times have been improved and their customers could not be happier.

Looking back Albert can now see the fruits of his foresight. His production process has been revolutionised in the way work moves through the Ariel Felicano (Operator) and Gary Finch (Foreman).

Building on the great results brought factory. Historically, jobs would sit by his first multi-tasking machine, on the floor between different machines, waiting to be set Albert recently looked to the market and decided to up for a process. As a result, multiple set-ups were required purchase his latest Mazak, an Integrex 200SY. He chose on machines with different controllers and often difficult this Integrex model because he considered it to be programming systems, stock was tied up in process and technologically superior to all other machines available. tooling and fixtures costs were higher.

The Integrex 200SY has all the benefits of the multi-tasking With the introduction of the Mazak Integrex 200Y multiseries but with the addition of an optional second spindle. tasking machine, Sharp Tooling is now able to quickly and The second spindle provides even greater flexibility with easily set up jobs for “done in one” production. in machine part transfer allowing second processes to be The majority of jobs on the new machine are short runs and performed automatically. The result is even fewer part set-ups.

Under the new arrangements, John Hart continues offer and support Brown & Sharpe, DEA and Leitz plus a new product range called Cimcore PCDMIS which is a portable arm CMM. Mr Bollito briefed staff on the new Hexagon regional facilities in Singapore which feature new offices, showrooms, training facilities and spare parts centre. The meeting served also to strengthen the links between the two companies who enjoy a long and close relationship.

Mr Bollito was also able to visit several customers to round off a very brief but fruitful visit.

>> Christchurch Engine Centre has the capacity When they needed to measure a fan blade set with a diameter in excess of 1.7m for the new IAE V2500 jet engine, the engineers at the Air New Zealand and Pratt & Whitney Christchurch Engine Centre thought they had met their match. However with help from the experienced engineers at John Hart they were able to meet the challenge.

The best machine for the application was the Global 20.33.15 fitted with the PCDMIS CAD++ software. The Global series is a range of extremely fast, high accuracy CMMs which have been recognised throughout the world as the industry standard.

Centre’s temperature controlled metrology room. As they already had PCDMIS software on their recently upgraded B&S Xcel CMM, they were up and running on the new machine straight away.

The new Global CMM allows measurement of large plasma coated rotor path liners and stator vane tips, blade tip diameters, snap and interface dimensions of their aircraft engines.

Talking with the process engineers at the Christchurch Engine Centre, they noted the machines large capacity, the PCDMIS software, the track V2500 jet engine record of Brown & Sharpe The Global CMM was the right choice because of its CMMs and the level of support provided by John Hart as advanced design, market leading software, large capacity factors in choosing the Brown & Sharpe. and excellent after sales support.

>> The Fanuc ‘Intelligent Robot’ - a vision for the future At the recent Automate 2004 show held at the Melbourne Exhibition Centre, John Hart Automation & Robotics (JHA&R) displayed a 200Kg payload robot mounted on an 8m gantry, a smaller LR Mate robot demonstrating flexibility through using tool changers and a R2000i robot using the new Fanuc 2D and 3D vision systems.

The world leading robot manufacturer Fanuc offers a full range of vision systems designed specifically to be used with Fanuc ‘Intelligent Robots’.

The result is an automated system which is extremely flexible in the way parts can now be presented to the robot and loaded into the machine.

To be able to see this world leading fully integrated 3D vision technology, JHA&R would welcome the opportunity to run a trial for you at our facility in Melbourne.

This means the hardware and software of the vision system are designed to interface easily with the robot ("plug and play") making setup extremely simple.

Vision systems have over the past few years, like robots, witnessed a vast increase in capability, user friendliness and robustness coupled with a reduction in up front and ongoing costs.

Traditionally robots have required parts to be accurately (and often expensively) positioned in order for them to be located. Now, with the new Fanuc vision system, a robot can locate a randomly placed part’s position and angular orientation automatically.

One major application for this technology is in machine loading, where suitable parts, castings or forgings arrive from the supplier in a stillage.

The vision equipment is able to view the stillage contents and determine the position and orientation of the easiest parts to pick up. The robot will then automatically adjust its gripper approach angle and pick up the part on the correct plane.

>> Getting it right first time, every time!

John Hart Automation and Robotics (JHA&R) has for the last six years utilised the state of the art Co-Create One Space Designer 3D solid modelling package for their project designs.

Our designers are able to model machines, robot grippers, safety cells and even whole factories in three dimensions prior to manufacture. The result is reduced project design time, increased design accuracy, pre project viewing of the project concept and automatically generated part lists and component specifications.

A good example is the recent design of a robot end-of-arm-tooling (EOAT) system for a palletising application in Melbourne. The customer’s brief specified that a robot was to handle a range of five cartons, each of from design different shapes and sizes with two different pallet sizes and one slip sheet. To complicate things further, the cartons had to be handled mechanically from beneath using tynes (not from above with vacuum cups) all within the robot’s capacity.

Starting by solid modelling the robot, cartons, grippers and surrounding equipment (like conveyors) the designer was able to create a complete virtual robot cell.

Once the cell was designed, features within One Space Designer checked for and eliminated any potential clashes between the gripper and other equipment in the cell. At the same time One Space solid designer was able to calculate the mass of the gripper simply by specifying the material being used for the individual components. This insured the robot had the lifting capacity for the application.

Once the design was finished, One Space Designer automatically generated detailed part drawings ready for manufacture.
