Damaged cutters

Damaged cutters

Cause:

1. Clearance between the upper and lower cutter is too small – min. 1/100 mm.
   
   
    
2. The bearings of the roller cutter have play → they need to be free of play!
    
3. The roller cutter shaft is heating up differently

a) Something touches the roller cutter => slowly turn the roller cutter by hand

b) the bearing is heating up too much => bearing defect!

c) If you have an exchange roller cutter => the roller cutter shaft might not be fixed properly to the side.

→ or the roller cutter shaft is too tensely assembled!
