Thermal isolation for continuous duty
External Motor Driven Spindles
With the motor mounted outside and coupled by belt or coupling, motor heat never reaches the spindle. That thermal isolation keeps accuracy stable through long continuous grinding runs, and makes the motor serviceable without stripping the spindle — the practical choice for 24-hour operation and retrofits.
