high quality custom design nylon delrin micro worm gear

Gears Made process
Milling
In the milling process, the gear is cut in a milling or jig grinder using a gear cutter and indexing or rotary table. The teeth of the gear are created by a rotating multi-edge cutter that creates teeth that are similar to the cutter. The cutter moves axially along the length of the gear tooth at the correct depth. Once the teeth are cut, the cutter withdraws, and a new blank is indexed.
The precision of the cutting depends on the accuracy of the cutter. Indexing is necessary to ensure all teeth are cut.
Grinding
Grinding uses several cutting edges at high speed and removes material at a fast rate to produce superior finishes and precise geometries. The process is ideal for hard materials; grinding of hard materials is referred to as hard finishing. A grinding machine is a multi-axes piece of equipment with bonded grinding worms called threaded wheels.
The threaded wheels are made of an abrasive material that is harder than the metal to be ground. The infeed X is set to the proper depth with a vertical feed rate Z and a lateral shifting motion Y that shifts the abrasive worm a small amount for the vertical feed rate.
