Aug 01, 2017

              Utility model discloses a sawing cutter head for granite cutting, including the cutter head body, the welding transition body, the welding transition body is a metal binder which is sintered together, wherein the cutter head body and the welding transition body are sintered with a hard wear-resisting phase on the outer surface of the bonded body; Welding transition body settings, the problem of welding quality caused by the difference between the metal composition of the cutter head and the steel strip is overcome, so that the cutter head body obtains a solid chip driving force, and the hard wear-resisting phase is set, which greatly improves the wear resistance of the surface of the cutter head. To protect the inner layer of carcass metal from abrasion, to ensure a smooth continuous cutting process, thereby effectively enhancing the metal binder on the diamond abrasive particles mechanical control, improve the processing efficiency and service life of the tool; in the process of forming hard wear-resisting phase, the mechanical control force of diamond abrasive and metal binder in the head body is greatly enhanced to meet the requirements of cutting granite.Hard granite blades
