2-1 Production Processes of Spur Gear
Illustrated here is a typical process of making spur gears.
Raw Materials :
Raw materials bought from material suppliers are kept in stock. The materials are six meters in length.
The materials are cut to size.
With a lathe, a cut workpiece is shaped into a gear blank.
Gear Cutting :
Gear cutting is done with a gear hobbing machine. The hobbing usually leaves burrs on the teeth.
Burrs on the teeth have been removed with a deburring machine.
Black Oxide Finish :
The black oxide finish is somewhat effective in preventing rust.
To ensure delivery in good condition each and every spur gear is individually packaged.
