Hob multiple gearings on workpiece with single setup

Hob multiple gearings with one setupBourn & Koch 100 H Horizontal Hobbing Machine

The Bourn & Koch 100 H horizontal hobbing machine can hob splines and geared shafts up to 100 mm in diameter.  Mount tools in combinations (shown above) to cut different gearings on one workpiece or to mill keyways and slots in one tool setup without reclamping. Since the chip conveyor is located directly under the tool spindle, chips are evacuated immediately from the machine to avoid any thermal distortions. In addition, the 100 H can be ordered with automation for machining larger lots.

This extended version of the 100 H with a NUM Flexium control can accommodate a workpiece up to 916 mm (36”) long and 126 mm (5”) in diameter. Request a budget quote by filling out our form.
