BUILT-IN SPINDLE
Micro Dynamics MEGA/TERA series standard with 15,000 rpm built-in-spindle. Spindle motor integrated with hybrid ceramic angular contact bearings. Drawbar has been rigorously tested to sustain more than 2 million cycles. For all applications, from heavy duty to high speed machining. Highest productivity under any conditions and complexities.
Micro Dynamics optional 18,000 rpm / 20,000 rpm spindle, available on all models. 20,000 rpm spindle delivers 35 kW of power and 119 Nm of torque. This allows for fine finishes while still achieving high material removal rates in a wide range of material types.
