CNC Milling Spindle
150XDJ15G26
Versatile synchronous motor spindle with BT40 interface. 26 kW output, 15,000 r/min speed, and 16.6 Nm torque for general CNC milling, drilling, tapping, and medium machining centers.
150XDJ15G26 CNC Milling Spindle
The 150XDJ15G26 is a versatile synchronous motor spindle designed for general-purpose CNC milling, drilling, and tapping in medium machining centers. With a 150mm housing diameter, 26 kW of continuous power, and 16.6 Nm of torque at 15,000 r/min, this spindle handles a broad range of materials and operations with consistent performance.
The G-type synchronous permanent magnet motor delivers excellent torque characteristics from low to high speeds, making it equally capable for heavy drilling and high-speed finishing. Equipped with P4 precision angular contact ball bearings in a tandem-O-tandem (TBT) arrangement, the spindle maintains runout accuracy within 1 micron under demanding conditions. The water-jacket cooling system ensures stable thermal conditions during extended production runs, while the standard BT40 tool interface provides compatibility with the widest range of toolholders and accessories in the industry. An optional HSK A63 interface is available for higher-speed applications. This spindle is ideal for general CNC milling, drilling and tapping operations, medium machining centers, and mixed-material job shops.
