Hardness is the main characteristic that determines the performance of abrasives. The super-hard abrasive itself has extremely high hardness, so it can process a variety of high-hardness materials, especially those that are difficult to process with ordinary abrasives. For example, use diamond abrasive tools to process cemented carbide, ceramics, agate, optical glass, semiconductor materials, stone, concrete and other non-metallic materials and non-ferrous metals; use cubic boron abrasive tools to process tool steel, die steel, stainless steel, and heat-resisting alloys, especially ferrous metals such as high-vanadium high-speed steel, can obtain satisfactory processing results.

Super-hard abrasives have less abrasion, long service life and high grinding ratio. Under reasonable use conditions, good economic effects can be obtained, especially for materials that are difficult to process with ordinary abrasives.

The shape and size of super-hard abrasives change very slowly during use, which is beneficial to the grinding operation. There is no need to change the concrete diamond grinding wheel frequently during processing, which can greatly save man-hours and is more suitable for automatic online processing of high-precision parts. Super-hard abrasives are rarely trimmed in use, and some super-hard resin-bonded abrasives tools do not even need to be trimmed, thus greatly improving working conditions.

Super-hard abrasives can keep sharp cutting edges for a long time, because the grinding force is small, which not only helps to improve the accuracy and smoothness of the processed parts, but also reduces the power consumption of the machine tool.

The grinding temperature of super-hard abrasive tools is relatively low, which can greatly improve the surface quality of the workpiece to be processed, and avoid the defects such as cracks, burns, and structure changes of the parts; it also greatly improves the stress status of the processed surface of the parts, which is beneficial to The extension of the service life of the parts improves the comprehensive economic indicators.
