BUILT-IN SPINDLE

Micro Dynamics MEGA/TERA series standard with 15,000 rpm built-in-spindle. The ATE motor in the spindle integrated with hybrid ceramic angular contact bearings, and its drawbar has been rigorously tested to sustain more than 2 million cycles. The remarkable solution for highest productivity for all applications, from heavy duty to high speed machining 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.

All Micro Dynamics spindles are built with all shelf standard bearings which can be replaced without removing the rotor. This makes all machines simple and fast to maintain. Rebuild costs are very low due to the availability of the parts and the short service time. (Except 20,000 rpm)
