KNECHT clamping nuts are characterized by an extraordinary innovation: the nuts compensate for linear expansions of the cutting system caused by temperature changes, e.g. in cooking cutters. Bending of clamping elements due to excessive clamping force is therefore impossible. This increases the breakage resistance of the cutter knives. Regardless of the operating condition, the knives are always clamped with the same force.
There is no friction between the clamping nut and the last ring of the clamping system and therefore no wear.
