# Nonstandard Precision Machining # Turning Processing What are the methods of gear processing?

1. Gear hobbing

The hobbing cutter and the gear to be processed are rotated according to the transmission ratio, and the tooth shape is gradually hobbing. Gear hobbing has high production efficiency and precision and is suitable for mass production.

2. Gear shaping processing

The gear shaping cutter reciprocates up and down and makes linear motion along the axis of the gear blank to cut the tooth shape. Gear shaping is suitable for processing internal gears, multi-link gears, etc.

3. Gear shaving process

Through the free meshing between the shaving cutter and the processed gear, trace amounts of metal on the gear tooth surface are removed to improve tooth profile accuracy and surface roughness.

4. Gear honing processing

Similar to gear shaving, it is used to further improve the tooth surface quality and accuracy of gears.

5. Gear grinding process

Using a grinding wheel to grind gear tooth surfaces can achieve high precision and surface quality, but the processing cost is high and is usually used for processing high-precision gears.

6. Gear milling processing

The use of milling cutters to process gears on a milling machine is generally suitable for single-piece small batch production and processing of low-precision gears.

During the gear processing process, it is necessary to select the appropriate processing method based on the gear's accuracy requirements, production batch, material and other factors, and strictly control the processing parameters and process to ensure that the quality and performance of the gear meet the design requirements.
