professional chuck-body rotation on its own base
B clamp jaws rotation No tool change time Thanks to 2 spindle heads , each with their own Automatic Tool Change. While a head is workingthe piece, the other one has already replaced its own tool and is ready at rotation speed. CNC Fanuc Dedicated to 5 axes machines. WORKING UNIT 2 (axes X/Y) Housing hydrostatic Spindle:Motor synchronous with 25 Kw Power 56 Nm constant torque up to 4300 rpm Acceleration time from 0 to 12000 rpm in 0.7”The motors with cold stator produce less heat,limiting the occurrence of expansion and improving the precision of the machine. HYDROSTATIC HOUSING • Less encumbrance to approach the part without interfering with the equipments•No static attrition , absence of wear and endless life potentially•High precision and repeatability• High rigidity and capacity of load.For example, 100 mm cantilevered housing radial load of 1000 N, flexion of 0.002 mm•Excellent behaviour to the damping of vibrations CHUCK WITH REVOLVING JAWS (axis A) Positioning continuous with
