I. Some details to be aware of when machining shaft parts!

- Jan 21, 2019 -

Shaft parts of the electric actuators are a common type of parts. They are constructed of rotating bodies and generally have a length greater than the diameter. They are widely used in various mechanical equipment to support transmission components, transmit torque and withstand loads. The processing of shaft parts must follow certain rules. You can find out the specific processing steps and some problems that need attention in this paper.


First, the basic processing route of shaft parts


The main machining surface of the shaft parts is the outer surface and the common special surface, so the most suitable processing method should be selected for various accuracy grades and surface roughness requirements. The basic processing route can be summarized into four.


The first is from the rough car to the semi-finished car, to the finishing car processing route, which is also the most important process route for the general external material shaft parts needle outer ring processing, followed by the rough car to the semi-finished car, Then to coarse grinding, and finally using the fine grinding processing route, for ferrous materials and parts with high precision, surface roughness requirements and hardened parts, this processing route is the best choice because grinding is The most ideal follow-up process; the third route is from roughing to semi-finishing, to finishing, diamond, this processing route is specially used to process non-ferrous materials, because non-ferrous metals are less hard and easy to block The gap between the sand grains is usually not easy to obtain the required surface roughness by grinding. The finishing and diamond car processes must be used. The last processing route is from roughing to semi-finishing, to coarse grinding and fine grinding. Finally, the finishing process is carried out. This kind of route is a processing route that is often used for hardening ferrous materials and requiring high precision and low surface roughness.
