The Bourn and Koch 100 H horizontal hobbing machine can hob splines and geared shafts up to 100 mm in diameter. Mount tools in combinations and cut different gearings on one workpiece or mill keyways and slots in one tool setup without reclamping the workpiece. 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 optionally be ordered with automation for machining larger lots. Star SU plans to exhibit an extended version of the 100 H with a NUM Flexium 68 CNC control at IMTS 2012 in Chicago, Illinois in September. This extended version can accommodate a workpiece up to 915 mm (36") long and 126 mm (5") in diameter.
