Machining Center Spindle
287XDJ10G75
Synchronous motor spindle with HSK T100 interface. 75 kW power, 551 Nm torque, and sub-micron runout accuracy for the most demanding CNC machining operations.
287XDJ10G75 Machining Center Spindle
The 287XDJ10G75 is a high-performance synchronous motor spindle purpose-built for CNC machining centers undertaking heavy-duty milling, high-speed cutting, and precision boring operations. With 75 kW of continuous power and 551 Nm of torque, this spindle maintains exceptional rigidity and cutting force across its entire 10,000 rpm speed range. The integrated motor-spindle design eliminates belt and gear transmission losses, delivering direct power transfer and superior dynamic response.
Equipped with P4/P2 precision angular contact ball bearings arranged in a permanent preload configuration, the 287XDJ10G75 achieves runout accuracy of 0.001mm or less at the tool interface. The spiral water-cooling jacket maintains stable thermal conditions even under continuous heavy cutting, while oil-air or grease lubrication options provide flexibility for different production environments. The standard HSK T100 tool interface ensures fast, repeatable automatic tool changes and excellent rigidity at the spindle nose. This spindle is engineered for die and mold manufacturing, aerospace component machining, and other applications where surface finish, dimensional accuracy, and material removal rates are equally critical.
