This how each cut is made Sheet metal is available in a very wide range of materials and alloys. The criterion for machining is a given toughness and strength to make the metal sheets deformable. A part of sheet metal machining is separation by shearing, in which the sheets are divided by two shearing knives. For over 40 years, we have supplied shearing knives in lengths up to 4,190 mm in qualities and hardnesses specially matched to the purpose for the corresponding machines. By using peripheral grinding machines, we can comply with the tightest form and position tolerances, which is why so many machine manufacturers rely on the quality of our shearing knives.
