Applications: advertising engraving machines, woodworking engraving machines, CNC machine tools, small machining centers, high-speed centrifuges and so on. Precision steel ball keeper is adopted, which guarantees the rotary accuracy of the motor spindle in high-speed grinding. The spindle shell is cooled by liquid circulation to reduce the temperature rise caused by high speed rotation. The spindle is specially designed for metal molds and dies, with high precision, low noise and full power. Special spindle for metal mold, dustproof and waterproof to prolong the life, stator lengthening cutting power., Manufacturer: QAXRZCUCD
