Abstract

The invention provides a diamond circular saw blade. The diamond circular saw blade is characterized in that the diamond circular saw blade comprises, by weight, 40-45% of metallic bonding agents, 30-32% of FC30 alloyed powder, 20-25% of copper and 6-8% of tin. A machining method for the diamond circular saw blade comprises the following steps of (1) working layer burdening, (2) pelleting, (3) cold pressing, (4) hot pressed sintering, (5) exposedness of a cutting edge, (6) paint spraying, and (7) detection and storage in a warehouse. According to the machining method for the diamond circular saw blade, a diamond bit tool and a steel base body are integrally formed through cold pressing, and welding is not required. Bonding force between part of the tool bit and the base body is strong, the phenomenon of tooth falling is not prone to occurring, a saw blade base body is assembled into a cold pressing forming steel mould, and forming is achieved through two-time feeding and one-time integral cold pressing. The phenomenon of piece burning is avoided, so that the saw blade cutting efficiency is stably and lastingly kept.

Description

technical field [0001] The invention relates to an integral cold press forming — Hot-pressed sintered diamond circular saw blades are mainly used for cutting granite slabs on hand-held cutting equipment. Background technique [0002] Overall cold forming — Hot-pressed sintered diamond circular saw blades are cold-pressed, assembled into cold-pressed steel molds in the order of "steel matrix → molding material", and directly press the molding material (the powder evenly mixed with diamond and metal binder) on the diamond Saw blades are placed on the circumference of the steel matrix, and then the cold-pressed forming pieces are sent to the hot-press sintering furnace to sinter the diamond saw blades, which means that the diamond blade and the steel matrix are cold-pressed as a whole without welding. The diamond circular saw blades produced by this process usually have a steel base diameter in the range of 100mm to 400mm. Among them, the steel base diameter below 250mm is ge...
