Application of Frequency Converter In Mechanical Outer Circular Grinding Machine
The frequency converter is widely used in modern industry due to its wide range of applications. With the rapid development of industrial technology, the use of frequency converters not only can meet the requirements of energy conservation and environmental protection, but also can improve the efficacy of mechanical equipment through its comprehensive optimization technology of energy saving, speed regulation and intelligent control. For example, it has been used in servo motor, robot, machine tool, drive system and so on.
In this paper, the application of frequency converter in mechanical grinding wheel processing machine is discussed. As we all know, grinding wheel machine is widely used in mechanical processing in many fields such as automobiles, machinery and so on. Performance and life of products have been improved by grinding wheel even processing. In order to achieve better processing efficiency and surface quality, the grinding wheel processing machine needs to select corresponding conversion component and grinding wheel. An appropriate frequency converter is also required to adjust the speed of the motor, which will be converted into linear motion then transmitted to the grinding wheel to achieve the required process speed, rate and accuracy.
Using frequency converter to running the mechanical grinding wheel processing machine not only can achieve high accuracy and low energy consumption, but also can make the processing efficiency better with its high speed control accuracy and function. The dynamic adaptive speed control technology provided by the servo motor drive system, combined with an optimized control algorithm, uses the proportional gap tuned PI controller to monitor the monitored motor speed and torque to improve the accuracy of servo motor, which can significantly improve the processing speed and quality accuracy.
It should be noted that, when selecting the frequency converter for the grinding wheel processing machine, the parameters should be reasonably selected according to the actual needs. Generally, the power of the frequency converter should be selected two to three times more than the rated power of the operating motor, because the motor will have a moment of inertia at the start. The frequency converter with frequency range of 0-400HZ and current range of 0-700A should be selected. The appropriate installation and protection measures should be taken according to the requirements of frequency converter manufacturer.
In short, the frequency converter has high performance and is widely used in mechanical grinding wheel processing. Its application can not only reduce the energy consumption, improve the accuracy and quality of the processing, but also improve the working efficiency of the grinding wheel processing machine. Therefore, more and more mechanical grinding wheel processing enterprises generally use frequency converter when they process products and components.
