Unique features Hardened and ground body and internal parts designed to avoid deformation, ensuring rigidity and accuracy. Easy installation to the machine. Indexing movement during spindle rotation, allowing a quick change between the multiple working axes. Indexing and clamping mechanism constantly oil lubricated and supported by strong systems of roller bearings. Very high maximum speed, with centrifugal force compensation system, for higher productivity performance. Very simple hydraulic system based on just 4 hoses, 2 for the indexing mechanism and 2 for the clamping piston. Internal mechanisms fully protected against contamination by coolant, chips and dust. Constant and automatic control of the position of the part and other working parameters by the C.N.C. of the machine, or by a separate electronic interface.
