Precision shaft installation of linear guides is not just a simple combination of parts and components.

Although the quenched and tempered piston rod has good comprehensiveness and high wear resistance, it is a connecting part supporting the piston to do work, but the premise to obtain these advantages is good processing conditions. In addition to the necessary molding process, the quenched and tempered piston rod also needs special grinding and hard chromium plating technology, and then polished by the mirror before it is finished and put into use. Precision axis
Firstly, the horizontal correction of the straight-line guide machine is carried out. Two equal-height gauge blocks and gauges are placed on the installation base, and the precise level gauge is put on the adjustment base. Secondly, the inspection work, including the installation of the basic surface roughness, flatness, straightness and appearance, to avoid the existence of defects.
The quenched and tempered piston rod is usually formed by rolling. A cold hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the workpiece surface and avoiding the burns caused by grinding. It can be seen that its processing is still demanding, and needs to be strictly observed.
