which factors for the wire edm machining efficiency
Wire EDM (Electrical Discharge Machining) involves the use of a wire electrode to cut through various metal materials, The efficiency of this process is crucial for several reasons, including pulse power,control software sytem,cutting materials,and working fluid,etc.
One of the key factors that contribute to wire EDM machining efficiency is the choice of pulse power supply. This used in this process is outputting the current to cut the workpiece. the max.current of pulse power was only 2 Ampere at the early stage,and the cutting efficiency was 1000mm² per hour.With the progress of technology,the cutting current can be achieved to 10 Ampere recently,therefore the max.efficiency of wire edm is 15000mm² per hour.those improve the workroom producing speed greatly.the latest no resistance pulse power has been used for the wire edm machine , the features of high efficiency and lower loss of wire are being recognized by more customers.
Another important factor is control system that involves the tracking function after cutting. means that the wire feed rate has to track the workpiece corrosion rate,and prevent the excessive discharge gap and short circuit at the same time.the wire feed rate often changes in accordance with the discharge gap,but the gap is not measuring in the actual machining process,so the control system can measure the voltage of gap to determine the gap value,and ajudust the wire feed rate.the new wire edm control softwar system has been added a latest tracking algorithm,that allow the tracking to be more accurate, and wire feed speeds up.So the wire edm efficiency can be higher than before.
Furthermore, The work-piece material can also influence the wire edm efficiency,These materials are selected for their high conductivity, which allows for efficient electrical discharge between the wire and the workpiece.if the material conductivity is low,the cutting speed will be low.additionally,the workpiece materials eg,aluminum,copper and titanium are all slow to process because their other characteristics.In general,the wire edm can cut the hardened steel at high speed,cutting the copper,aluminum or titanium at medium speed,cutting the materials low conductivity at low speed.
The dielectric working fluid is another factor that affects wire EDM machining efficiency. The cutting speed refers to the rate at which the wire electrode moves through the workpiece. Many impurities and oxides are produced in the wire discharging area that temperature is 5000 degree celsius.which can influence the speed of wire edm cutting workpiece.the working fluid is needed to flush away the impurities to clean the working area to make the machine work at nomal speed.Two requirements:1. no impurity in the working fluid, 2. flushing the workpiece constantly,we have installed the water tank with two 5um filters and high-pressure pump.allow the working fluid to be clean and circular flow.The working fluid and two filters must be replaced every 20 working days. Using the right dielectric fluid ensures optimal performance, reduces wire breakage, and enhances the overall efficiency of the proces
wire EDM machining efficiency is crucial for cost-effectiveness, time-saving, and overall productivity. other factors such as wire tension, electric feed block, wire electrode materials, also can influence the cutting speed during the working process. Selecting the qulity wire edm machine is essential for achieving optimal efficiency in wire EDM machining. By considering these factors and implementing best practices, manufacturers can enhance their productivity, reduce costs, and deliver high-quality products to their customers.
