With the widespread use of steam engines and the subsequent development of large-scale machinery such as mines, metallurgy, ships and locomotives, more and more metal parts need to be formed and cut. The metal materials used have evolved from copper and iron to steel.
However, the CNC machining industry has a wide variety of grinder products, and the size of the workpiece is different, and the machining accuracy is different. Compared with the grinding machine, the grinding wheel speed is different from that of the spindle grinding machine. It is difficult for the grinding machine to adjust the spindle grinding machine speed to meet the workpiece grinding machine processing linear speed to the ideal state. In addition, due to the stress bending of the grinding machine caused by the machining process of the shaft, the grinding process will produce different torques of the grinding wheel feed to the grinding machine, which will bring about the grinding wheel output speed/torque different grinding machine changes, and the corresponding grinding machine will produce vibration knife marks/burning marks, etc. , Grinding accuracy is difficult to guarantee, resulting in low production efficiency and low quality rate.
