Hobbing Machine for Gear Production

The increasing number of automobile gears, especially as automatic transmissions are developed with 10-gear systems, allow cars to run for longer periods of time within optimal rpm ranges, thus increasing fuel efficency. This results in increased pressure on the optimization of gears and their production. High-volume gear manufacturing systems must increase speed and precision. The VLC 200 H demonstrates how.

"Shifting up a gear" in the production of gears

Flexible solution

The automated, high-performance package of the VLC 200 H hobbing machine can be integrated in a production system in various ways. Directed parts flow, as well as cyclical automation or connection via "Chaku-Chaku" enables the high-production manufacturing of gears.

Minimum idle times

The pick-up principle ensures low idle times during production of gears. The spindle lifts the gear from the conveyor and moves it to the tailstock, where it is provided maximum rigid support. After hobbing, the spindle transports the gear out of the work area.

Short processing times

The two water-cooled direct drives on the process-relevant axes, as well as on the milling head and the main spindle ensure high performance. Gear wheels with a diameter up to 200 millimeters and module 4 can be efficiently dry milled with a short machining time. Wet machining is an optional possibility.

Shortening the process chain

After turning the blanks, on a VL 2 lathe, for example, the gear cutting process starts on the VLC 200 H. Double-sided chamfering is performed with a VLC 100 C. This massively reduces the cycle time for a gear wheel.
