HSD MTR 1320-200 Spindle Repair & Heavy Industrial Rebuild
Overview
The HSD MTR 1320-200 represents an even higher torque tier within the MTR line. It is built for:
- Industrial panel production
- Aerospace composite trimming
- Heavy structural routing
- Continuous-duty CNC machining
Official Technical Specifications HSD_Cat_Composite_mar24_Web_ENG…
- Body Diameter: 177 x 145 mm
- Max Speed: 18,000 rpm
- Torque S1/S6 (40%): 13.4 / 16.1 Nm
- Power S1/S6 (40%): 17 / 20.4 kW
- Rated Voltage: 380V
- Taper: ER32

High-Duty Failure Patterns
Because torque is higher:
- Bearing fatigue occurs earlier under overload
- Thermal stress increases during extended cycles
- ER interface wear accelerates under aggressive feeds
Rebuild Strategy
- Heavy-load bearing replacement
- Shaft runout verification
- ER32 taper inspection
- Cooling airflow validation
- Rotor balance
- Extended thermal test
