304不锈钢性能优良,在煤矿机械设备中得到广泛应用。而电火花线切割技术具有加工灵活、降低模具制造成本等一系列优点,是切割加工的理想选择。而电参数、走丝速度等参数是影响电火花线切割加工质量和加工效率的重要因素。通过正交实验研究了峰值电流、脉冲宽度、脉宽脉间比值以及丝速等主要工艺参数对电火花线切割加工切缝宽度、切面粗糙度和加工效率的影响规律,并分析了其中的原因,得出一系列相关结论。对电火花线切割加工过程中工艺参数的选择具有一定的参考价值。
304 stainless steel excellent performance, widely used in coal mining machinery and equipment. The WEDM technology has the flexibility to reduce the cost of mold manufacturing and a series of advantages, is the ideal choice for cutting. The electrical parameters, take the silk speed and other parameters affect the quality of WEDM processing and processing efficiency of the important factors. The effects of main current parameters such as peak current, pulse width, pulse width and inter-pulse width ratio, and wire speed on cutting width, cutting surface roughness and processing efficiency of WEDM were studied by orthogonal experiments. , Come to a series of related conclusions. The selection of process parameters in the process of WEDM has certain reference value.
