Electric spark processing technology is widely used in mechanical industry, automobile industry and other fields. It has become an important manufacturing method due to its high machining accuracy, high efficiency and low cost. Traditional electric spark processing generally uses frequency control of power supply, workpiece processing is affected by the effect of power supply itself and environment conditions, which leads to the inconsistent processing quality. The basic contradiction of electric spark processing technology and its solutions are discussed below.
The basic contradiction of electric spark processing technology is that the output current of traditional electric spark processing power supply needs to meet certain requirements. If the output current is overspecified or underspecified, the machining efficiency and accuracy will be affected, which will lead to the inconsistent quality of electric spark processing.
Solution 1: Using automatic tracking power supply. The new type of electric spark processing power supply can automatically track the preset working parameters, which can effectively avoid the above problem. The power supply has self-learning and self-adaption features, which can adjust the output current and output current time in a very short time to adapt to any changes in the working environment.
Solution 2: Using closed circuit electric spark processing. By increasing the effective utilization rate of electric energy and improving the electrical characteristics, the current loop is closed. This mode is more beneficial for improving the machining accuracy and machining efficiency.
Solution 3：Using heat radiation equipment in electric spark processing. High temperature and high current intensity lead to higher heat radiation and reduce the machining efficiency and accuracy. Therefore, proper cooling measures and heat radiation equipment should be added in electric spark processing.
The above three solutions are the main measures adopted by electric spark processing technology to improve its machining accuracy, machining efficiency and machining quality. Taking into account the environment of electric spark processing, if the working environment is dynamic, it is more suitable to use automatic tracking power supply, which has the best flexibility. In production, closed loop electric spark processing system has higher accuracy and higher efficiency. If it is affected by the high temperature of the working environment, it is necessary to add the cooling device and heat radiation equipment. The measures of electric spark processing technology to improve the processing accuracy, efficiency and quality can effectively alleviate the basic contradictions and greatly improve the processing effect.
