CNC Milling Spindle
160XDJ18G18
Robust synchronous motor spindle with BT40 interface. 18 kW output, 18,000 r/min speed, and 9.5 Nm torque for automotive parts machining, general CNC milling, and precision drilling.
160XDJ18G18 CNC Milling Spindle
The 160XDJ18G18 is a robust synchronous motor spindle engineered for demanding CNC milling and drilling applications in automotive parts manufacturing and general precision machining. With a 160mm housing diameter, 18 kW of continuous power, and 9.5 Nm of torque at 18,000 r/min, this spindle excels in high-productivity machining environments.
The synchronous permanent magnet motor delivers strong torque across the entire speed range, making it ideal for both heavy drilling operations and high-speed contour milling. Equipped with P4 precision angular contact ball bearings in a tandem-O arrangement, the spindle maintains runout accuracy within 1 micron. The water-jacket cooling system with optimized flow channels ensures stable thermal conditions during continuous production cycles. The standard BT40 tool interface provides broad compatibility with industry-standard toolholders and accessories, minimizing tooling costs for job shops and production facilities. This spindle is ideal for CNC milling and drilling, automotive powertrain and chassis component machining, general precision machining, and mixed-production manufacturing environments.
