Integrated Motor, Production-Ready

ATE motor (German made) is integrated with hybrid ceramic angular contact bearings. The Micro Dynamics drawbar has been rigorously tested to sustain more than 2 million cycles.

  • CTS (Coolant Through Spindle) designed to sustain up to 100 bar (1,500 psi)
  • CTS preparation is standard equipment; CTS system is optional
  • For all applications - from heavy duty to high-speed machining
  • Highest productivity under any conditions and complexities
