The dynamic accuracy is directly related to the rigidity of each part of the punch, and the dynamic accuracy of the punch with good rigidity is relatively high.
If the high-speed punch is loaded, the structure and other pressure-bearing structures will be deformed. Therefore, the static accuracy will deteriorate, that is to say, the dynamic accuracy is the real accuracy.
There is a very close relationship between the accuracy of the punch press, the accuracy of the product and the life of the mold.
The dynamic accuracy is directly related to the rigidity of each part of the punch, and the dynamic accuracy of the punch with good rigidity is relatively high.
The dynamic accuracy, which is very important in actual stamping processing, has not been integrated and formulated due to the technical difficulties in formulating specifications. The current situation is that static accuracy represents the accuracy of punching machines.
