The EDM process is introduced in detail. Electrical discharge machining (EDM) is the use of electrical energy to produce sparks between the tool and the workpiece embedded in dielectric, which is called EDM through partial melting or vaporization.

Electrical discharge truing e

Whether CBN, diamond or traditional corrosive materials are used, they all need dressing or dressing to obtain high-precision grinding. However, due to the hardness of the wheel materials, the dressing of these grinding wheels is difficult. Therefore, these super corrosive grinding wheels are made of soft bonding materials to facilitate dressing or dressing the grinding surface. This results in a shorter life of the grinding wheel.

In order to improve the grinding performance of metal bonded diamond wheel, proper adjustment method must be adopted. In this paper, the wire discharge dressing was evaluated. With the self-designed werd device, the dressing process can be carried out in the grinder, reducing the non production time.

Difference between edg and ecg

The similarities and differences between EDM and ECG are shown in the table below. The similarity between EDG and ECG is that only conductive workpiece material can be processed by EDG and ECG, because in both cases, the workpiece is an electrode.

Abrasive electrical discharge grinding

Abrasive discharge grinding of AEDG. The introduction of mechanical effect in EDG process can improve the metal removal rate. For example, for Al SiC composites, the removal rate of AEDG process is 10ms, the removal rate of n500rpm is about 5 times of that of EDG process and about twice of that of EDG process.

Electrical discharge grinding versus abrasive grinding

EDM grinding and conventional grinding are two different methods for PCD machining of polycrystalline diamond, which have different removal mechanisms. This paper discusses the quality of PCD tools produced by these two processes. Although the surface roughness and tool sharpness of the two processes are very similar, it is found that the residual stress and tool sharpness are similar
