Metal spacer is used on slitter shaft to adjust different distance between slitting knife according to needed width of coiling strips. Same high pricision as slitting knife's; Reasonable price, not as expensive as knife of raw material; Wear resistance, but lighter for machine shaft to ensure higher precision of slitting strip and easier assembling.
