Gear hobbing is a process in which gear is cut by a generating process by rotating the gear blank and the cutter called a hob at the same time with a fixed gearing ratio between hob and gear blank. In this process the gear blank is fed towards the rotating hob until the required depth is reached. The hob is fed across the face of the blank ...
UNIMILL is a milling method for the manufacture of prototype bevel gears using end mills or disk cutters. 30 Hob Tool Life Technology Update ( March/April 2009 ) The method of cutting teeth on a cylindrical gear by the hobbing process has been in existence since the late 1800s.
May 19, 2016· Types of milling machine: There are various milling machines are used in mechanical industries. These are described below. 1.
