The cooling system is used to cool the spindle and cutter. Common cooling methods include water cooling, oil cooling and air cooling, which can improve machining accuracy and prolong tool life. The lubrication system provides necessary lubrication for the spindle and bearings, which can reduce friction and wear to improve service life. The cutter clamping device can fix the cutter to ensure its stability and safety during high-speed rotation. Common clamping devices include spring collets, hydraulic clamps and heat-shrink clamps. In terms of key technologies, to achieve high-speed rotation, the spindle often uses composite ceramic bearings, electromagnetic levitation bearings or static pressure bearings. These bearings are wear-resistant, heat-resistant and have long service life. The spindle motor adopts a design that integrates the motor with the spindle. Dynamic balance at high speed is a key technology. Lubrication generally uses timed and quantitative oil and gas lubrication or grease lubrication to ensure the normal operation of the bearings.
