Main function:

1Measurement of working length.

After use, the molds have varying degrees of wear, which can cause changes in working length and increase the weight error of individual pieces. So after using it for a period of time, it is necessary to check the consistency of its working length.

2Measurement of coaxiality between punch body and punch head

During the use of the mold, bending or plastic deformation caused by excessive pressure or other reasons can affect the installation of the mold and increase the weight error. Therefore, it is necessary to inspect it after a period of use.
