The fineblanking process in detail
Fineblanking allows highly accurate parts to be produced without the need for secondary operations on the sheared faces. The material is restrained during the shearing process and cannot escape. This allows parts to be accurately blanked and formed in one and the same operation.
The accuracy of the fineblanking process is Swiss precision at its best.
Comparison with conventional stamping
Conventional stamping generates tearing or breakout in the sheared faces. As a rule, stamped functional surfaces require secondary operations.
