What's the difference in shape and function of the shaper cutter, shaving cutter and gear hob?
The shaper cutter is like a straight gear, and the front face of the cutter is concave taper in order to form the rake angle, and the machining accuracy of the gear is higher (than hobbing).The shaving cutter is like a helical gear, and the cutter teeth are arranged in a longitudinal groove, which is used for fine machining after slotting and hobbing.The hobbing cutter is shaped like a worm and is arranged along the axial direction, and belongs to the rack type gear cutter.
There are pictures and documents in the attachment, and the processing methods and principles of each tool are explained
Slotting cutters are cutters used on slotting machines, which mainly process internal and external gears. The hobbing cutter is a tool for processing gears on a gear hobbing machine. It can process gears other than internal gears. The shaving cutter is a cutting tool for shaving gears on a shaving machine, mainly finishing the gears. Structurally different
