Air precision vice APC-N

APC-N-Vices with high accuracys are the ideal chucks for precise mill- and bore- operations, which have high requirements to concentricity, flatness and parrallelism.Variable clamping forces which are resulting out of a fine adjustment of the air pressure are enabling the clamping of thin walled and fragil workpieces without deforming. All models have an opening for coolant as standard. With sizes from 75 to 250 mm as standard and different jaw strokes, we can supply chucks for a wide range of applications.
