Ten reasons for chip jumping of precision die in high speed stamping
In high-speed stamping, after the blanking and shearing, the material sheet which should be left in the cutting edge jumps out and falls on the die surface, which is called chip skipping
The causes are as follows:
1. Blanking shape
2. The gap between blanking holes is too large
3. Split mold
4. Punching speed
5. The punch is short
6. Too much oil or too much stamping oil
7. The mold parts are not demagnetized sufficiently
8. The vacuum cleaner is installed in the wrong position or the vacuum cleaner is not opened after installation
9. The contact area between punch and material is large
10. The new cutting edge or the newly ground cutting edge is easy to produce chip jumping
