ELC 160 laser welding machine

ELC 160 HP – “High-performance” laser welding machine for gear components and clutch bodies

The ELC 160 HP is used especially for laser welding of the control gear and clutch body. It combines several process steps into a perfectly timed system.
Joining (press fitting), induction pre-heating (if required by the material) and connecting the components by laser welding.

ELC 160 HP: New flexibility in joining and laser welding of the control gear and clutch body

All machine components are mounted to a central column. A rotary indexing table arranged around this column provides for the transport of parts to the respective process stations. Each processing position on the turntable is provided with its own spindle unit, on which the workpiece is cycled horizontally to its processing positions.   Position one is used as the loading and unloading station. Both gantries and robots can be used here. The joining station follows after one cycle step around the table. The joining station is equipped with three joining stamps that are mounted to a slide, which allows rapid re-tooling for part families. The joining process itself is performed rapidly and precisely by a screw spindle drive. Another quarter turn later, the workpiece reaches the processing station for induction pre-heating, if this is required by the workpiece material. Here as well, several inductors can be installed in parallel in order to permit rapid adaptation to different parts. One turn of the indexing table later, the workpiece has reached the core of the machine, the laser welding station. This station as well is equipped with a slide unit with up to three counter bearings in order to ensure automatic re-tooling at this point as well. The weld head is equipped with an X-axis for the seam position and a Z-axis for adjusting the focal position.
All four processes described above run in parallel, allowing extremely short cycle times of only a few seconds.
