The cylindrical line discharge shaping of metal bonded diamond grinding wheel. The purpose of this study is to study the wear and grinding performance of metal bonded diamond wheel by WEDM under the guidance of Albert.
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.
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.
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 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.
Discharge grinding electricity. The combination of ECG grinding and ECG discharge is the combination of ECG grinding and electrical discharge grinding. This paper begins with a schematic diagram of an ecdg device using a solid sticky stone ink wheel. Send email protected email chat online
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
EDM grinding EDG is more and more popular in the manufacture of polycrystalline diamond PCD tools. In this paper, the effects of machining parameters and feed processing on the surface quality of PCD corroded by EDG are studied.
EDM grinding EDG is very similar to EDM, except that the electrode tool is a rotating graphite grinding wheel. Starting from the schematic diagram of EDG wheel setting, this paper discusses the control operation of EDG setting. The typical applications and conditions of EDG are listed...

Heat treatment technical information. Rough grinding may leave high spots, these spots will wear prematurely, burrs will fall off, and uncoated edges will be left behind. Grinding burn glass and cracks on tools must be avoided to provide the most suitable surface for PVD coating polishing. The combined compound and stress must be minimized
Metal bonded diamond wheel is an important tool for precision grinding of hard and brittle materials, especially ceramics and cemented carbide. However, its wide application is affected by the problem of shaping. Aiming at the dressing of metal bonded diamond arc wheel, a new type of EDM dressing device is developed.
EDM grinding EDG is a variant of EDM, which is often used to manufacture PCD tools to shorten machining time. In this paper, the quality of two-step and three-step machining PCD inserts by two different EDG erosion methods is studied. Surface roughness and residual
