The Application of Encoders in Machine Tools

from20Since the emergence of CNC technology in the mid-20th century, CNC machine tools have brought revolutionary changes to the mechanical manufacturing industry. CNC machining machines have the following characteristics: good machining flexibility, high machining accuracy, high productivity, and reduced workloadoperationImproving labor intensity and working conditions are conducive to the modernization of production management and the enhancement of economic benefits. Numerical control machine tools are highly integrated electromechanical products. The development trends of CNC machine tools include high-speed, high-precision, composite, intelligent, open, networked, multi axis, and green,

The development trend of CNC machine tools

1高速化 With the rapid development of industries such as automobiles, defense, aviation, and aerospace, andaluminum alloyWith the application of new materials, there is an increasing demand for high-speed CNC machining. （1）Spindle speed: The machine tool adopts an electric spindle (built-in spindle motor), and the spindle speed can reach200000r/min； （2）Feed rate: at a resolution of0.01μmWhen the high feed rate reaches240m/minAnd it can achieve precise machining of complex surfaces;

2High precision The requirements for precision of CNC machine tools are no longer limited to static geometric accuracy. The motion accuracy, thermal deformation, and monitoring and compensation of vibration of machine tools are increasingly valued. （1）ImproveCNCSystem control accuracy: Using high-speed interpolation technology, continuous feed is achieved through small program segments, enablingCNCRefine the control unit and adopt high-resolution position detection devices to improve the accuracy of position detection (Japan has developed and installed...)106pulse/The position detection accuracy of the AC servo motor with internal position detector can reach0.01μm/Pulse), the position servo system adopts methods such as feedforward control and nonlinear control; （2）Adopting errorscompensationTechnology: Adopting techniques such as reverse clearance compensation, screw pitch error compensation, and tool error compensation to comprehensively compensate for the thermal deformation error and spatial error of the equipment

3 :functional integrationmultifunction machineThe meaning of a bed refers to the process of processing multiple elements from raw materials to finished products on a single machine tool, or as much as possible. According to its structural characteristics, it can be divided into two types: process composite type and process composite type. Process composite machine tools such as boring, milling, and drilling composites——Machining center, turning and milling composite——Turning center, milling boring drilling car composite——Composite machining centers, etc; Process composite machine tools such as multi-faceted multi axis linkage machining composite machine tools and dual spindle turning centers.

Product Application

1 /Position detection and feedback of machine tools

2 /Measurement of motor and spindle speed and positioning

3 /Other special machine applications

Measurement principle

Magnetic induction encoder is based on magnets, integrates magnetic sensing components, and is designed as a magnetic induction type

Non contact sensing head is used to sense the number of teeth on the gear and process the signal through circuit correction or segmentation
