What needs to be reminded here is that the high speed punching machines should pay attention to the following items when installing and adjusting the accuracy of the bed guide rail:
1. Pay attention to the stiffness of the foundation.
2. The ambient temperature should not change too much, and avoid direct sunlight and other heat sources (it is best to adjust in a constant temperature workshop).
3. Use precision measuring instruments (such as optical and laser collimators, electronic levels, etc.) to reduce measurement errors.
4. Make sure that the adjustment shim is in good contact with the connection surface of the foundation and the bed, so as to avoid the precision change caused by poor contact and ensure the stability of the punch precision.
5. When tightening the anchor screws, the force should be uniform, and the tightness of each screw and nut should be consistent, so as to ensure that the high-speed punch bed can be evenly pressed on the adjustment pad iron.
After adjustment, leave it for 24 hours and then recheck the accuracy of the guide rail of the bed. If the change is large, it should be readjusted. After the high-speed punch press has been in operation for one year, the accuracy of the bed needs to be adjusted again.
