High-Torque Milling Spindle
170XDJ10G52 HSKA80
Extreme-torque synchronous motor spindle with HSK A80 interface. 52 kW power, class-leading 497 Nm torque at 10,000 r/min for the most demanding heavy milling operations.
170XDJ10G52 HSKA80 High-Torque Milling Spindle
The 170XDJ10G52 HSKA80 is an extreme-torque synchronous motor spindle engineered for heavy-duty milling applications that demand maximum metal removal capability. With 52 kW of power and an extraordinary 497 Nm of torque delivered at up to 10,000 r/min, this spindle ranks among the highest torque-density electrospindles in its class.
The permanent magnet synchronous motor provides full torque from near-zero speed, enabling aggressive roughing cuts in steel, stainless steel, titanium, and superalloys without stalling. P4/P2 precision angular contact ball bearings in a rigid tandem-O-tandem arrangement handle the extreme cutting forces while maintaining sub-micron runout accuracy. A high-capacity water-cooling system with enhanced flow channels dissipates the substantial heat generated during prolonged heavy cutting. The HSK A80 tool interface provides an optimal balance of rigidity and weight for large cutting tools. Housed in a remarkably compact 170mm diameter body weighing approximately 220 kg, this spindle maximizes torque output within a space-efficient envelope for horizontal machining centers and specialized heavy-cutting machine tools.
