Grinders (Main)

Diamond and CBN wheels, Resin, Galvanic, Metal and Vitrified bonds.

Due to their comparatively high price, superabrasives can only be used economically when they enable a high material removal ratio combined with a low specific wear compared to conventional abrasives such as aluminum oxide or silicon carbide.

The low wear of diamond grinding wheels - even with high drawability ratios - enables the machining of materials that are difficult to rough, with tight tolerances in shape and size and high quality finishing requirements.

The cost comparison between conventional abrasives and diamond shows that the diamond provides greater savings in the machining of carbides and similar materials difficult to thin, provided that proper grinding machines are used.

The grinding wheel must meet a number of requirements in order to provide a well-suited solution for the task and sharpening, both in the technical and economic aspects. The grinding wheel must be capable of providing the required workpiece finish, ie the desired quality (roughness and surface integrity), shape, dimensions, flatness, straightness and similar requirements, it must remove the required material volume in the minimum possible time , and should be as long as possible.
