Hobbing with Chamfer Cut in One Set-up

The new LIEBHERR LC 180 Chamfer Cut in one set-up hobs and generates the precise and reproducible chamfers required by the automotive user without adding to part cycle times.

The new machine integrates a complete second machining unit for Chamfer Cut tools – in effect, two machines in one – avoiding any increase in machining cycle time. Time savings comes from two simultaneous operations in the machine at once in two separate machining positions: gear hobbing on a stable, maximum-rigidity device, and chamfering on a simpler, collision-optimized fixture.

The solution can chamfer both face edges of the workpiece without the usual change of rotation direction, creating an additional time advantage. Also, the length of the hobbing tool can be maximized, enabling total tool costs to be further reduced. Simple setup through the Liebherr touch screen CNC.
