Operation Guide For CNC Gear Hobbing Machine

The workpiece is installed on the workbench of the gear hobbing machine, driven by the indexing worm gear pair to rotate, and forms a generative motion together with the motion of the hob. When hobbing helical teeth, the differential mechanism makes the workpiece make corresponding additional rotation. 

The worktable (or column) can move along the guide rolling of the bed to adapt to different workpiece diameters and radial feed. The tool holder of some hobbing machines can also move along the axis of the hob, so that the worm gear can be processed by tangential feed method. The large gear hobbing machine is also equipped with a single tooth indexing mechanism, a finger milling cutter holder and a differential reversing mechanism for machining herringbone gears.
