The difference between EDM wire cut machine and traditional cutting machine

EDM wire cut machines and traditional cutting machines are both common cutting equipment in industrial production, but their working principles and cutting effects are very different. In this article, we will conduct a detailed analysis and comparison of the differences between EDM wire-cut machines and traditional cutting machines.

First of all, the traditional cutting machine cuts the workpiece through mechanical force, while the EDM wire cutting machine cuts the workpiece through discharge to generate a high-temperature and high-voltage arc. This is also one of the biggest differences between the two. Traditional cutting machines require the use of cutting tools for cutting, while EDM wire cut machines use electrode wires for cutting. The electrode wire is a thin wire that generates a high-temperature and high-voltage arc through discharge to cut the workpiece into the desired shape. Therefore, the cutting speed of the EDM wire cut machine is slower than traditional cutting machines, but the cutting accuracy is higher.

Secondly, EDM wire cutting machines can cut harder materials, such as steel, tungsten, molybdenum, etc. Traditional cutting machines can only cut some softer materials, such as iron, copper, aluminum, etc. This is also one of the reasons why EDM wire-cut machines are widely used in industrial production.

In addition, there is no mechanical force during the cutting process of the EDM wire-cutting machine, so no mechanical deformation will occur. The traditional cutting machine will produce mechanical deformation during the cutting process, which affects the cutting accuracy. Therefore, an EDM wire cut machine is more suitable for occasions that require higher cutting accuracy.

In addition, EDM wire cutting machine does not produce chips during the cutting process, because there is only discharge between the electrode wire and the workpiece during the cutting process, and no mechanical force is exerted on the workpiece. The cutting process of traditional cutting machines will produce a large amount of chips, which need to be cleaned. Therefore, an EDM wire cut machine is more suitable in situations where the waste generated during the cutting process is required.

Finally, the cutting process of the EDM wire cut machine requires the use of working liquids, such as deionized water, mineral oil, etc., to cool the electrode wires and workpieces, and also to clean the deposits generated during the cutting process. Traditional cutting machines do not require the use of working fluids. Therefore, an EDM wire cut machine is more suitable in situations where the heat generated during the cutting process is required.

To sum up, EDM wire cut machines and traditional cutting machines are very different in terms of working principle, cutting effect, cutting speed, cutting accuracy, chip generation, waste generation, heat generation, etc. When selecting cutting equipment, you need to make your selection based on your specific production needs and requirements.
