CNC Milling Spindle
210XDJ15G15
Compact synchronous motor spindle with BT40 interface. 15 kW power, 95 Nm torque, ideal for small to medium CNC machining centers and high-speed milling.
210XDJ15G15 CNC Milling Spindle
The 210XDJ15G15 is an economical yet high-performance synchronous motor spindle designed for small to medium-sized CNC machining centers. Delivering 15 kW of continuous power and 95 Nm of torque at speeds up to 15,000 r/min, this spindle offers an excellent balance of capability and cost-effectiveness for general machining, light production, and job shop environments.
The permanent magnet synchronous motor provides fast acceleration and consistent speed holding, ensuring quality surface finishes across a range of materials from aluminum to alloy steel. P4 precision angular contact ball bearings deliver sub-micron runout accuracy for tight-tolerance work. The efficient water-cooling system maintains stable operating temperatures without complex ancillary equipment. Featuring the widely compatible BT40 tool interface and a compact 210mm housing diameter, the 210XDJ15G15 integrates easily into both new machine builds and spindle replacement programs. Weighing approximately 140 kg, it is well-suited for machines with limited spindle cartridge space.
