Machining method of shaft parts

Let me help you with the processing methods of bearings

According to the different structural forms of shaft parts, they can generally be divided into three types: optical shaft, stepped shaft and special-shaped shaft; Or it can be divided into solid shaft, hollow shaft, etc. They are used to support gear, pulley and other transmission parts in the machine to transmit torque or motion.

The processing technology of step shaft is typical, reflecting most of the content and basic rules of shaft parts processing. Next, take the transmission shaft in the gearbox as an example to introduce the processing technology of the general step shaft.

For parts with high accuracy requirements, rough and finish machining shall be separated to ensure the quality of parts.

Transmission shafts are mostly rotary surfaces, which are mainly formed by turning and cylindrical grinding.

Reasonable selection of positioning base turning amount can be determined by workers according to processing conditions during single and small batch production, which plays a decisive role in the size and position accuracy of parts.
