Problems solved by technology

[0002] There are many materials used in the production of conventional diamond saw blades, and the diamonds are randomly distributed on the saw blades, resulting in the inability of the diamonds to fully perform their functions. When the conventional saw blades are working, they have large cutting resistance, high energy consumption, low efficiency, and poor precision, which limits The normal use of diamond saw blades also limits the scope of use of diamond saw blades and hinders the development of cutting technology

Abstract

The invention discloses a diamond spiral locating and distribution ultrathin layer composite saw blade and a manufacturing technology thereof. The technical scheme is that a working layer ultrathin piece of which the thickness is 0.1 mm to 1.0 mm and an isolation layer ultrathin piece are compounded into a saw blade segment; a working layer ultrathin piece blank of the segment is made from the raw materials of metal powder and diamond, and the isolation layer ultrathin piece of the segment is made from the raw materials of graphite powder, silicon carbide powder, aluminium oxide powder and ceramic powder; during cold press molding of the working layer ultrathin piece, a spiral locating and distribution structure is adopted, and diamond particles are embedded in reserved positions in a blank; during the loading process, ultrasonic or other high-frequency vibration platforms are adopted to vibrate to distribute materials, the thickness of the blank is uniform and consistent, and then, the saw blade is manufactured through a hot pressing sintering technology; and the segment is welded on a saw blade matrix of which the diameter is 100 mm to 2500 mm through a high-frequency or laser welding technology. According to the manufactured ultrathin layer composite saw blade, working efficiency is high, service life is long, energy consumption is low, and resources and energy are saved.
