High precision mirror axle bar is a cylindrical object which is pierced between high precision mirror axle bar bearing or wheel or gear, but a few of them are square. High precision mirror axle bar is a mechanical part that supports and rotates a rotating part to transmit motion, torque or bending moment. One is usually a metal rod, each section can have a different diameter. The rotating parts of the machine are mounted on the high precision mirror axle bar.

Cause of wear

The wear of high precision mirror axle bar is the most common equipment problem in the use of high precision mirror axle bar. There are many reasons for wear of high precision mirror axle rods, but the main reason is that the metal properties used to manufacture high precision mirror axle rods are determined. Although the metal has high hardness, it has poor yieldability (it can not be recovered after deformation), poor impact resistance and poor fatigue resistance, so it is easy to cause adhesion wear, abrasive wear, fatigue wear, fretting wear and so on. The wear of some high-precision mirror axle bars is not easy to detect. Only when the machine is in high temperature, large jump range, abnormal noise and so on, people will be aware of it. But when people find out, most of the high-precision mirror axle bars have been worn out, resulting in machine shutdown.
