Tolerance average (For formats length of 2000 mm.)
- Length ±0,2 mm.
- Diagonal ±0,5 mm.
Indicated tolerances and productions are in function and related
with following factors:
- Strip Tension stability and fluctuations
- Strip quality and surface smoothness
- External factors such electromagnetism and mechanical vibrations
- Machine operator skill
