There are two reasons for the inconsistency 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 the workpiece material and the surface quality of the workpiece. For example, when the workpiece is cast iron, the cast iron plate wears a lot; when the workpiece is a soft metal such as copper or aluminum, the wear is small; the workpiece with a rough surface is likely to scratch the surface of the cast iron plate.
Workplaces are not clean and, in addition to causing errors in accuracy, can also increase the wear of cast iron slabs.
Excessive force measurement of the workpiece causes deformation or earlier wear of the cast iron plate.
Incorrect use of cast iron slabs, such as the use of flat plates to inspect workpieces with rough surfaces can cause rapid wear and the like.
