The relationship between coupling modulation treatment and metal heat treatment

There are two reasons for the inaccuracy of cast iron plates:

(1) Normal wear or abnormal wear during use;

(2) Damage caused by improper use and storage.

The factors that cause wear are:

When the surface hardness of the cast iron plate is low, it is easy to wear.

The influence of workpiece material and workpiece surface quality. For example, when the workpiece is cast iron, the cast iron plate wears more; when the workpiece is soft metals such as copper and aluminum, the wear is small; the rough surface of the workpiece is easy to scratch the surface of the cast iron plate.

Unclean workplaces will not only cause accuracy errors, but also increase the wear of cast iron plates.

Excessive force measurement of the workpiece will cause deformation or early wear of the cast iron plate.

Improper use of cast iron flat plates, such as using flat plates to inspect workpieces with rough surfaces will cause rapid wear.
