A gear shaper cutter is essentially a modified gear that cuts the tooth profile of a workpiece gear through backlash-free "meshing" (i.e., generating motion). It can machine various types of cylindrical gears, including external spur and helical gears, internal gears, and double gears with narrow ... Read More
