1. Ways to avoid the grinding tool being hooped:
Use a special seal cavity.
In the production process, often keep cutting sharp, demagnetization.
Expand the cavity gap.
Choose abrasives with sloped tooth surfaces rather than flat ones.
2. The key reasons for the rapid damage of the die base are:
Abrasive clearance is small. It is usually recommended that the total clearance of abrasive is 20%~20% of the thickness of raw materials.
Convex and concave abrasives for weak acid is not good, including die base, abrasive guide parts, CNC punch blade accuracy is not enough.
Die base temperature is too high, the key reason is the same grinding tool for a long time to cause the punch temperature over.
