The shearing principle permits deformation of the material, but there is no material loss in the form of waste chips. During cutting, the upper cutter blade moves towards the fixed lower cutter blade. This exerts high tension on the material being processed, and a so-called advancing crack.
In shearing, the material is cut off at high speed, and the total shear force of the moving cutter blade is exerted fixed cutter blade.
Advantages:
- Flexible in curves
- Fast, accurate cutting
- Long tool life
- Chip-free cutting
- Good cut quality
