Grinders can process materials with higher hardness, such as hardened steel, hard alloy, etc; It can also process brittle materials, such as glass and granite. The grinder can grind with high precision and small surface roughness, and also can grind with high efficiency, such as powerful grinding.
Grinders and grinding wheel motors used in standard machining are operated according to the traditional starting circuit. After the motor is started, it operates at the rated speed. Because the grid voltage fluctuates to a certain extent, the friction load of the grinding wheel workpiece changes constantly, which will affect the motor speed error.
The starting circuit of the standard grinding wheel motor generally has only one processing speed, which is difficult to adapt to different workpiece sizes and different processing relative linear speeds, so that it is difficult to guarantee the processing precision of the processed workpiece. Therefore, from the aspects of improving the processing quality and efficiency, saving energy and so on, the application of frequency conversion speed regulation technology to grinding machines can achieve satisfactory results.
