Difference Between Spindle Motor And Servo Motor Of Stone Carving Machine
2019-03-18 15:17:12

1. The requirements of stone carving machine for spindle motor and servo motor. The requirements of different stone carving machine for feed servo motor are as follows:

(1) Mechanical characteristics: small speed drop and high stiffness of servo motors; (2) fast response requirements: this is more stringent in profile processing, especially in high-speed processing of objects with large curvature; (3) speed range: this can make CNC machine tools suitable for various cutting tools and processing materials; suitable for various processing processes; (4) certain output rotation. Torque, and require a certain overload torque. Our stone trimming machine tool feeding mechanical load is mainly to overcome the friction of the table and cutting resistance, so it is mainly the "constant torque" nature.

The main requirements for spindle motors are as follows:

(1) Sufficient output power, the load property of the spindle of stone carving machine is similar to "constant power". That is, when the spindle speed of machine tool is high, the output torque is small; when the spindle speed is low, the output torque is large; that is, the spindle drive device is required to have the property of "constant power"; (2) speed range: in order to ensure that the stone carving machine is suitable for various cutting tools and processing materials; Due to different processing technology, Guizhou stone edge grinder requires a certain speed range of spindle motor. But the requirement of the spindle is lower than that of the feed; (3) Speed accuracy: generally, the static difference is less than 5%, and the higher requirement is less than 1%; (4) Speed: the spindle drive device is sometimes used in positioning function, which requires it to have a certain degree of rapidity.

The power system of stone carving machine is stepper motor and servo motor. Both of them are controlled by pulse train and direction signal, but their performance is quite different.
