What are the types of tooth surface processing of rail racks?

1. Production and processing of tooth surface forming method:

Forming production and processing usually refers to the production and processing of product workpieces by making full use of forming tools. The guide rail rack manufactured in this way has a low degree of rack and can only be used in the natural environment of low-speed movement. The common production and processing methods of the forming method include tooth milling, forming tooth shaping, tooth pulling, and forming tooth grinding, among which tooth milling is commonly used. Gear milling usually refers to the method of directly cutting gears on a milling machine with a forming gear milling cutter. The production and processing characteristics of milling teeth are convenient production and processing, low cost, but their productivity is relatively low.

2. Production and processing of tooth surface generation method:

Generating production and processing usually refers to a method of making full use of product workpieces and tools for generating cutting motion for production and processing. He makes full use of the meshing motion of the guide rail and rack pair to realize the cutting of the tooth profile. The common production and processing methods of the generating method are gear hobbing, gear shaping, gear shaving, gear honing, gear grinding, etc., among which gear hobbing and gear shaping are commonly used. The production and processing of the generating method requires a gear processing machine tool, and the processing accuracy is high.
