In the grinding operation with CBN diamond grinding wheel, in addition to the very important life of the grinding wheel, the understanding of the quality factors of the grinding wheel is also crucial in order to meet the high requirements for the grinding process and machining accuracy.

The grinding process has always played a very important role in the machining of tools and components. Compared to other types of cutting technology, the advantages of the grinding process are its good machinability for hard materials, high dimensional tolerance accuracy (IT5~6) and small ripples and roughness of the ground surface. Degree (Rz = 1~3μm).

Since the basic shape of the electroplated grinding wheel is extremely plastic and easy to cut, this process is particularly suitable for demanding processing applications. The electroplated layer of the grinding wheel is characterized in that, on the one hand, it is necessary to grind the particles by high quality to meet the requirements of the wear limit range, and on the other hand, it is necessary to leave a space for discharging the chips.

Overall observation of the grinding process

Due to the increasing complexity of the machining process, an overall observation of the grinding process is necessary. This means that specific requirements are imposed on the configuration of the grinding wheel used, depending on the application. At this time, the surface shape (ie, the area of action of the cutter head) is often involved. In order to be able to describe and evaluate the relevant surfaces in a specific way, modern measurement techniques and methods must be used. This allows an objective assessment of the results and quality levels of the tool flow with particles at any point in time. This is also a prerequisite for ensuring a stable processing quality.

During electroplating bonding, the grinding wheel particles are deposited onto the conductive disk by precipitation of the electrolyte and nickel or chromium. This process has random features that affect the quality characteristics being detected. In order to characterize the wheel lining, a large variety of different detection features are employed. Important features obtained by inspection are bond hardness, particle size and particle density. In addition, data such as the number of blade statics, the number of blade dynamics, and the blade pitch are also used to evaluate the tool surface. The latter two parameters already contain the dynamics of the process, and with today's advanced measurement technology, the measurement cost will be higher.
