A further option on the Type 79 was a pneumatic-control device (Part 20.21.00/0) that allowed all functions of the machine to be automated. An alternative fitting was that shown below, Part 20.24.00/0 a semi-automatic attachment whereby the machine was started by hand but the cutting feed engaged under pneumatic control.

the machine feed constant (M). This is the distance in inches that the hob advances for one revolution of the work when the feed gear ratio is 1 to 1. The value of these constants varies with the different models of this series of hobbing machine and with the number of threads on the index worm. The last constant is the "C" constant and

Construction Of Gear Hobbing Machine Hob – In this process, the gear blank is rolled with a rotating cutter called a hob. Gear hobbing is done by using a multipoint cutting tool called gear hob. It looks like a worm gear having a number of straight flutes all around its periphery parallel to its axis.

hobbing yields better tool life, and!convention-al hobbing yields a better finish, In all. cases, the cutting force should be directed against the work spindle, never against the tailstock. The directions of feed on a hobbing machine correspond to the work axis ..Thus, three feeds are possible - axial, radial and tangential (Figs. 12a, b, c).
