For numerical control milling and processing center for requirement of low speed high torque, so have to main shaft transmission torque reduction ratios of ascension, but the accuracy is poor due to low speed is inevitable, so can not use small radius of the cutting tool. Spindle for CNC engraving and milling machine just can work in 2 ~ 30000 RPM, rotary accuracy of 2 m or so commonly, or cutting knife phenomenon will be very serious, so be sure to use electricity the main shaft, the motor and spindle are one and the same: for high speed cutting equipment, invisible motorized spindle, and also want to use a certain amount of torque when low speed, want to have to keep oil and water cooling machine spindle working temperature, constant power spindle to 7. More than 5 ~ 8 kw, of more than 25000 RPM.
