As a high-performance mold material, cemented carbide has many advantages such as excellent wear resistance, high temperature strength, strong corrosion resistance, and strong compressive resistance. Therefore, tungsten carbide is widely used in a wide range of fields. However, the processing of cemented carbide is a more complex and difficult process, Zhuzhou Chuangrui Cemented Carbide Co., Ltd. shares with you the cemented carbide EDM, let's take a look how to precaution for tungsten carbide EDM:
With the continuous development of society and the progress of science and technology, cemented carbide machining has gradually shifted from traditional cutting to grinding and EDM, including forming and wire cutting. However, no matter what kind of processing method, cemented carbide material cannot escape the fact that it is a difficult material to process.
In cemented carbide EDM, the setting of processing conditions is extremely important, if the selection is not appropriate, it is easy to make surface defects such as cracks, which will have a greater impact on the service life of cemented carbide dies, and even the danger of scrapping.
There are few points need to be note:
1.Tungsten carbide is prone to cracking and collapse under impact and excessive machining loads, and tungsten carbide must be machined firmly on the table before machining.
2.Tungsten carbide has extremely low magnetic properties, and non-magnetic carbide has no magnetism at all. Do not fix the carbide with magnets, fix it with clamps. Before machining, please double-check whether the workpiece is loose. If yes, fix the workpiece firmly.The machining surface of hard alloy after cutting and grinding will be very smooth, with sharp angles.
3, Cemented carbide is a material with extremely high hardness and brittleness, and it is forbidden to beat cemented carbide with a metal hammer.
Precautions for discharge machining and wire cutting machining of hard alloys
1.Tungsten carbide has high hardness and good wear resistance, so the operation process need to be more slower when discharging and wire cutting.
2.The surface of tungsten carbide is easy to cracks and collapse angles after processed by mirror spark machine, so please adjust the processing plan according to the use conditions of the product.
3.Cracks often appear during online cutting of hard alloys, and it is necessary to confirm whether there are defects on the processed surface before proceeding to the next process.
Zhuzhou Chuangrui Cemented Carbide Co., Ltd. has more than dozens of EDM equipment, including slow wire cutting, precision wire cutting, high-precision EDM, fast punching machine and other equipment, which can meet the cutting of cemented carbide precision matching parts, upper and lower special-shaped parts, gear helical gears and other workpieces, and has a special EDM production workshop for cemented carbide EDM processing to meet customer requirements for special processing of products.
