Without 10 years of technology, it is impossible to do high-precision linear guide heat treatment

With the innovation and development of high-tech in our country, the technology of linear guides for transmission parts has gradually become proficient. Mechanical designers, production managers and automation developers who are familiar with linear guides know that they are mainly used in linear reciprocating motion occasions, and have Higher load characteristics than linear bearings, bearing a certain torque coefficient. The high-speed linear guides are partially made of high-carbon chromium bearing steel with super wear resistance. After heat treatment and density grinding, the surface hardness can reach more than 70HRC, which greatly prolongs the service life of the linear guides.

When our company receives a consultation from a guide rail manufacturer, we will recommend suitable equipment according to some technical requirements provided by the other company and the desired effect. Starting from the selection of customer’s raw materials, according to the working conditions of the linear guide, it is hoped to meet the requirements of comprehensive mechanical properties and better temperature resistance and dimensional stability. According to the requirements of high strength, high hardness and high wear resistance of its working parts, our company recommends the material is generally high carbon tool steel, imported carbon structural steel can also be used.

The heat treatment process selected for the linear motion guide rail is high-frequency quenching and low-temperature tempering. The user generally adopts the technological process recommended by our company as follows: Guide rail rack – cylinder feeding – conveying roller to – feeding positioning – high frequency quenching on both sides at the same time – discharging positioning – ultra-sonic low temperature tempering – discharging roller table – cylinder pushing material – discharging rack.

Through this set of automatic linear guide quenching equipment, the user’s linear guide can achieve the following advantages:
1. Increase surface hardness
2. Significant increase in service life
3. The quality of the product is higher
4. Increase the comfort of sliding
5. Reduce the maintenance cycle of the guide rail
