The 45mm asynchronous motorspindle with P9 automatic direct shaft clamping tool interface assures high quality. The quadruple ball bearing arrangement with ceramic hybrid ball bearings, a runout less 1µm and the labyrinth system at the spindle front guarantee a process reliability. The rear ball bearing package and the shaft are preloaded by springs for higher axial stiffness. With an optimized motor adjustment it reaches full torque at low speed (at 3.500 RPM). All spindle parts are hardened and grinded. All rotating parts are balanced less G1 at maximum speed.
