EDM is a common machining method, especially in the field of mold injection molding. It is irreplaceable and plays a very important role. We all know that each product will have corresponding advantages. It is these advantages that make each tool stand firm, and so is electric spark. It is precisely because of its unique advantages that it is widely used. Today, let's introduce the seven advantages of electric spark.

1. The machining process is hardly affected by heat, so the thermal shock layer can be reduced and the workpiece with high machining quality can be processed.

2. The hardness of the tools used in EDM is not harder than that of the materials, so it is easier to process and manufacture.

3. Contact with spark machine every day or everyone in the machining industry knows that EDM machine is processed without contact, and the tool electrode and workpiece are not in contact during machining; Compared with other machining methods, it does not produce workpieces. Hard wound.

4. Any two-dimensional surface with a straight line as a bus can be machined without manufacturing complex tool electrodes.

5. The processing of all excess materials will not be processed into waste, which improves the utilization of energy and materials.

6. It can cut about 0.05 mm narrow gap. The WEDM efficiency is generally 20-60 mm2 / min, the maximum is 300 mm2 / min, the machining accuracy is generally (+ 0.01-0.02 mm), and the maximum is (+ 0.004 mm). The surface roughness is generally r2.5-1.25 microns, the maximum is ralpha 0.63 microns, and the cutting thickness is general. 40-60mm, up to 600mm thick.

7. EDM can realize the vertical angle of the workpiece, which is impossible because milling must have R angle.
