Gear hobbing machine is a widely used type of gear machining machine, which can cut straight and helical cylindrical gears, as well as worm gears, sprockets, etc. A gear machining machine that uses a rolling cutter to machine spur, helical, and herringbone cylindrical gears, as well as worm gears, using the unfolding method. This machine tool can also process various special tooth shaped workpieces such as splines and sprockets when using specially designed rolling cutters. The machining accuracy of ordinary gear hobbing machines is 7 to 6 levels (JB179-83), while high-precision gear hobbing machines are 4 to 3 levels. The larger processing diameter reaches 15 meters.

Performance characteristics of gear hobbing machine:

(1) Small batch and single piece production of cylindrical helical gears and worm gears, and can also roll cut spline shafts with a certain parameter range

(2) Easy to adjust, with automatic parking mechanism

(3) A gear hobbing machine with reliable safety devices and automatic lubrication is a widely used machine tool in gear machining. It can cut straight and helical cylindrical gears, as well as worm gears, sprockets, etc. on the hobbing machine.
