The solid carbide milling cutter is more and more widely used in aerospace, mold manufacturing, automobile manufacturing, and machine tool manufacturing, especially in high-speed cutting.

In the field of high-speed cutting, the solid carbide milling cutter has more stringent internal and surface quality requirements due to the high standards of tool safety, reliability, and durability. With the improvement of the intrinsic quality of the cemented carbide bar, especially the ultra-fine cemented carbide cutter, the surface quality of the solid carbide milling cutter has been paid more and more attention. As is known to all, the service life of solid carbide milling cutter is not only related to its wear resistance but also often manifested in abnormal failures, such as breaking edge, breaking edge, etc., the surface defects, such as grinding cracks, are one of the important reasons for the abnormal failure. These surface defects include Powder metallurgy defects (such as delamination, cracks, unpressed, holes, etc.) within the cemented carbide bar exposed to the surface after grinding and grinding, as well as grinding cracks caused by improper grinding of the ground surface during grinding, grinding cracks are more common. These grinding cracks are easy to be missed by conventional inspection methods such as naked eye, magnifier, oil-immersed sand-blowing, stereo microscope, and tool microscope, missed cutting tools, especially in high-speed cutting situations, can cause serious consequences, so the risk of grinding crack defects in solid carbide milling cutter products is significant. Therefore, it is of great practical significance to analyze and discuss the causes of grinding cracks of solid carbide milling cutter and put forward effective measures to prevent grinding cracks.
