With the continuous development of cutting tool materials, the shapes of cutting tools have also undergone constant changes. Initially, it was the solid cutting tools, then the carbide cutting tips were brazed onto the tool shank, and further advancements saw the cutting tips being clamped onto the tool shank or the tool body using mechanical clamping systems. Consequently, the market for cutting tool grinding also emerged.

Mechanical blades are used by mounting the entire superhard blade with effective cutting edges onto the original tool holder or tool body through a mechanical fastening method. If all effective cutting edges are ground and discarded, they can be used as indexable inserts. It has been found that meat grinder blades, especially with the popularization of CNC machine tools, indexable inserts can accurately determine the position of the cutting edge, eliminating the need for re-grinding and making a significant contribution to labor saving and productivity improvement. However, considering the limited resources, it is necessary to conduct research on resource conservation rather than simply discarding them. Therefore, blade grinding has always been a resource-saving practice.

The emergence of superhard alloys produced by powder metallurgy has made it possible to cut harder materials at higher speeds and with greater efficiency. This has led to the practical application of sintered cutting tools such as synthetic diamond and cubic boron nitride (CBN). Inserts made of these materials are relatively difficult to manufacture, and their grinding is also challenging.

On the other hand, compared to this superhard blade material, the so-called high-speed steel also needs to be reevaluated for its performance improvement. Among the types of materials, high-speed steel is divided into tungsten-based and platinum-based varieties, with a wide range of types and applications, especially widely used in forming tools and in areas where superhard alloys have disadvantages in the low-speed range. Due to the variety of blade materials, shapes, and types, the conditions for blade grinding also vary. Therefore, knowledge about blade materials, tip shapes, grinding wheel selection, and blade grinding methods are becoming increasingly important.
