High precision mirror axle core is a cylindrical object which is pierced between high precision mirror axle core bearing or wheel or gear, but a few of them are square. High precision mirror axle core is a mechanical part which supports and rotates with rotating parts to transfer motion, torque or bending moment. Generally, it is a metal rod with different diameters. The rotating parts of the machine are mounted on the high precision mirror axle core.

Cause of wear

High precision mirror core wear is the most common equipment problem in the use of high precision mirror core. There are many reasons for wear of high-precision mirror axle core, but the main reason is that the metal characteristics used to manufacture high-precision mirror axle core are determined. Although the metal has high hardness, it has poor resilience (can not be restored 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. Part of the wear of high-precision mirror axle core is not easy to detect, only when the machine is high temperature, large jump range, abnormal noise and other conditions, will cause people to notice, but when people find out, most of the high-precision mirror axle core has been worn, resulting in machine shutdown.
