Problems solved by technology

[0002] In the production of conventional diamond saw blades, the thickness of the saw blade is relatively large and the material used is large, and the diamonds are randomly distributed on the saw blade, resulting in the inability of the diamond to fully exert its effect. The material to be cut is wasted, and at the same time, the cutting resistance, high energy consumption, low efficiency and poor precision during the working process limit the normal use of diamond saw blades, limit the scope of application of diamond saw blades, and hinder cutting Further development of processing technology

Abstract

The invention discloses a diamond radial locating and distribution full-working layer ultrathin saw blade and a manufacturing technology thereof. The technical scheme is that the saw blade is directly formed through a powder metallurgy manufacturing technology; the diameter of the saw blade is 10 mm to 800 mm, the thickness of the saw blade is 0.2 mm to 2.5 mm, the saw blade is composed of a blank working layer and mounting holes, and the blank working layer is made from the raw materials of meal powder and diamond; a radial locating and distribution structure is adopted, and diamond particles are embedded in reserved positions in a blank according to the designed diamond particle interval size; and during the loading process, ultrasonic or other high-frequency vibration platforms are adopted to vibrate to distribute powder, the thickness of the blank is uniform and consistent, and then, the saw blade is manufactured through a hot pressing sintering technology. According to the manufactured diamond radial locating and distribution full-working layer ultrathin saw blade, arrangement of diamond is reasonable, efficiency during utilization is high, service life is long, saw kerfs are narrow, energy consumption is low, and resources and energy are saved.
