VL MACHINES IN OPERATION VL 2 and VL 4 for small and medium-sized workpieces The VL 2 and VL 4 pick-up turning machines are ideal for workpieces with a maximum diameter of 4 and 8 inches. The machines feature an integrated automation system and a parts storage area that allows them to operate completely autonomously, relieving the strain on production personnel. Efficient mass production of various batch sizes is possible with these machines and, thanks to their flexible clamping systems, they can also easily machine entire part families.

THE TRACKMOTION AUTOMATION SYSTEM TrackMotion combines the concept of conveyor belts integrated with gantries into one single automation solution.

The TrackMotion is a track that runs through multiple machines with a TransLift unit attached. The TransLift will grip parts, even parts with different heights, correctly position them and if necessary turn the part over. The way the TrackMotion is set up it can link a variety of machines very easily. To decrease cycle times even further, multiple TransLift units can be added.

THE VL PLATFORM I Automating the VL Series

THE ADVANTAGES OF THE TRACKMOTION SYSTEM + Minimal set-up time – the TrackMotion automation system is ready for use as soon as the workpiece height and part diameter have been entered into the standard CNC Code

The raw components are supplied by a parts storage area.

This has a capacity to hold up to 400 parts, depending on the geometry of the workpiece.

+ Great reliability due to its simple, sturdy design

+ Flexible system – multiple TransLift

units can be installed on a single system

+ The workpieces are positioned and turned over in one cycle

+ Save space - the whole system is installed behind the machines

+ Possibility to integrate measuring

equipment, marking systems, cleaning machines and more

+ Easy to service – TrackMotion is easily accessible from all sides

From small to large with no retooling.

The universal NC gripper ensures that the machine can be reset very quickly.

+ Short part transport times with horizontal travel speeds of 492 ft/min and 92 ft/min vertically

VLC 50 TWIN – HIGHLY PRODUCTIVE SIMULTANEOU Twin-spindle turning center for the highly productive manufacturing of workpieces up to 75 mm (3 in) in diameter The VLC 50 TWIN has two main spindles in one machining area which can simultaneously machine two identical workpieces. This method allows for massive increases in output quantities and lowers cost per piece.

HIGH SPEED LINEAR MOTOR

The diameter and length (X / Z direction) of both components can be corrected independently of one another using both spindles. In addition, the machine has a direct position measuring system and a linear motor in the X-axis to ensure the highest machining quality and maximum productivity.

HIGHLIGHTS + Maximum precision

Machine base made of MINERALIT® polymer concrete with optimal vibration-damping properties, size 45 linear roller guides, as well as direct position measuring systems in the X-axis, for the highest positioning accuracy, repeat accuracy and long-term accuracy.

+ Integrated automation

Two pick-up working spindles for loading and unloading. “Automation ready”: Linking with other EMAG machines / technologies (e.g., gear hobbing) possible thanks to TrackMotion automation system.

THE VL PLATFORM I The VLC 50 TWIN

MACHINING

+ Unique TWIN concept

Simultaneous machining of two identical workpieces is possible, which means doubling the output and reducing the cost per piece. Diameter and length (X / Z direction) of both components can be adjusted independently of one another.

+ Maximum dynamics

Linear drive in the X-axis for maximum dynamics, minimal wear and maximum positioning accuracy.

Automation included

On the VL 1 TWIN machines, the working spindles are not only used to machine workpieces, but also to load and unload them. This saves money, space and unnecessary peripheral devices.

HEAVY-DUTY MACHINING OF COMPLEX WORKPIECES The VM 9 vertical turning center is designed for the production of individual parts or small/medium production runs with a wide variety of parts. The machines tool turret has twelve tool positions, and depending on the interface desired by the customer (BMT or VDI), the turret can be equipped with driven tools. This allows for additional manufacturing flexibility as the machine can be equipped for a variety of things, for example drilling operations. Based on customer requirements, the workpieces can either be loaded manually using a crane, or automatically through the side loading door.

In order to guarantee consistently high workpiece quality, the machine has an integrated probe installed (first part = good part). With all of these features included, the VM 9 is extremely well equipped for a wide variety of production tasks.

VERTICAL TURNING CENTERS I VM 9

+ Maximum productivity: Highly dynamic axes for short idle times and quick machining processes

+ Simple handling: All the service units are easy to reach + Automation concept (optional): Loading through the

side loading hatch with a gantry or robot. Direct access to the machining area through the separate front door

+ Maximum performance: Thanks to short transport distances

+ High surface accuracy: Axis monitoring by rotary, indirect absolute encoders or with a fully encapsulated linear glass scale (optional)

+ Ideal for heavy-duty machining: Generously dimensioned main spindle, maintenance-free spindle motors and rigid guideways

+ Very long workpiece service lives:

Very rigid machine body made of MINERALIT® polymer concrete, six to eight times better damping properties than gray cast iron

HIGH PERFORMANCE SHAFT PRODUCTION When it comes to producing a high quantity of shafts, fast manufacturing processes are crucial. In order to achieve this, the loading and unloading of the machine must be done very quickly.

The VT 2 and VT 4 machines guarantee maximum performance with their four axes, short travel distances and powerful main spindles. The benefits of this machine are obvious when required to produce high part volumes. Since this platform can machine the workpiece from two sides, the production time is dramatically reduced allowing for more parts to be machined, quicker. The machines flexibility is also guaranteed by the two tool turrets, each with eleven tool stations, that can be equipped with turning or driven tools.

THE BENEFITS + The standard machine comes prepared for integration with the TrackMotion automation system.

+ Reduced machining times due to four-axis machining

+ Shorter idle times with simultaneous

loading and unloading of components

+ Lower investment costs thanks to integrated automation

AUTOMATION SEQUENCE The gripper in turret 1 takes a workpiece from the raw parts storage area and transports it to the main spindle/tailstock.

At the same time, the gripper in turret 2 takes the machined workpiece from the main spindle/tailstock and transports it to the finished parts storage area.
