EMAG VL 3 Duo Vertical Turning Machine Offers Extremely Compact Machining Solution, TrackMotion Compatibility
When EMAG launched the new TrackMotion automation system in 2015, they quickly realized that it not only focused on transporting parts, but on the combination of machine tool, raw parts storage facility and a standard automation solution to create a highly efficient production line.
The consistent adjustment of the automation to the modular machines from its internal production makes it possible to create manufacturing systems using a modular kit.
So it will come as no surprise that EMAG unveiled another world first, a direct development of the modular machines in combination with the TrackMotion automation system - the VL 3 Duo.
When you first see the machine, you'll immediately notice how compact it is. "We need just 13 m² (140 sq ft) to install the complete VL 3 Duo," explained Peter Loetzner, CEO at EMAG L.L.C. "For a twin-spindle vertical pick-up turning machine, that is a fantastic size. Even if the machine is combined with a raw parts storage facility and the TrackMotion automation system, the dimensions for a complete manufacturing system for chucked parts up to 150 mm (2 inches) is almost laughably small. That makes the VL 3 Duo one of the most compact and efficient systems available from EMAG."
With its parts ranging up to 150 mm (2 inches) in diameter, the VL 3 Duo is ideal for the manufacturing of gearbox components such as, for example, machining blanks for gear wheel production. "Gearbox components such as gear wheels must be manufactured in very large quantities. The standard production process is always the same: in OP 10 and OP 20, both sides of the gear wheel blank are machined by a turning process and the surfaces are prepared; the gear cutting process follows in OP 30 and deburring takes place in OP 40," explained Loetzner. "The VL 3 Duo is, of course, primarily focused on the first process in this machining chain, in other words OP 10 and OP 20, which can be implemented perfectly with our system."
The VL 3 Duo can be fitted with EMAG's TrackMotion automation system as an option. The automation system consists of three central parts, the track (i.e. the rails) on which the TransLift NC gripper runs and the raw parts storage facility. The entire system is very compact and runs directly behind the machining areas of the VL 3 Duo. The TrackMotion always focuses on the individual component. Each transport process only moves a single component which allows for significant benefits for component management. The increased mobility of the TransLift, including the Z-axis, means that stackable pallets can be used on the raw parts storage facility, making it possible for the raw and finished parts to be stacked with minimal space requirements. In addition, the TransLift is also used as a changer between the two machining operations. This means that the TrackMotion automation system provides everything required for compact manufacturing on the VL 3 Duo: an extensive parts storage area that accommodates up to 400 parts and a fast, flexible parts transport system between the various manufacturing stations.
Like every modular machine, the VL 3 Duo has its own parts buffer and a pick-up spindle in each machining area. The TrackMotion automation system loads the individual part pallets on the parts buffer as they shuttle between the loading position near the machining area and the rear section of the machine. From there, the working spindle takes the raw part, transports it into the relevant machining area and places the part back onto the appropriate pallet after it has been machined. Immediately next to it, the subsequent part is waiting to be picked up by the spindle, so that only a few seconds pass until the next part is being machined.
The machining areas are arranged in a mirror constellation and each has its own working spindle which, with a rating of up to 18.1 kW and torque of up to 142 Nm, has plenty of power for high speed, precision machining.
In addition, each machining area has a tool turret with twelve tool positions which can be fitted with turning tools or driven tools. "The turrets can also be fitted with an additional Y-axis to extend the range of uses of the machine even further," explained Loetzner.
The VL 3 Duo adds a highly productive, compact manufacturing system for large-scale production to EMAG's modular machine family.
"Its real strength can be seen when it is connected to other machines in the modular machine family," said Loetzner. "Let's look at the example of gear wheel production mentioned above. If we supplement the VL 3 Duo with the VL 4 H, the modular gear hobbing machine from EMAG, and a VLC 100 CC or VLC 100 RC, the vertical chamfering and deburring machines, we create a manufacturing system for gear wheels, which is completely linked using the TrackMotion automation system, with a very small footprint. The whole thing is made possible by the standard structure of the modular machines, the integrated automation system and the fact that the transfer height between the machines is always identical - it's simply brilliant! In other words, almost as simple as using building blocks."
