cutters with alloy teeth were fitted on the cutter head of machines for boring vertical shaft and for raise boring. This type of cutter was developed based on milled tooth cutters. The body was made oT wear-resistant cast steel, 30 CrMn SiTi, and the tooth wag made of alloy steel, YG nC. The cutter body was heat-treated with complicated technology. The hardness is HRC 37-41. It had good toughness against impact and fracturing. A proper shrink range between the alloy tooth and tooth hole was chosen. The alloy tooth was cold-pressed into position. X-ray measurement and metallographic analysis indicated that after assembly, it was still within the range of elastic deformation and elastic stress. Experiments were made with satisfactory results on finishing accuracy, roughness, shrink range, pressing force and guide device for pressing teeth. The service life and reliability of the cutters have reached the world advanced level.
