Common process of diamond circular saw blade
(1) Electroplating method: A variety of diamond tools can be manufactured using electroplating method. The electroplating method is carried out under normal temperature and pressure. It does not damage the diamond and is easy to operate. It is especially suitable for manufacturing special-shaped diamond tools, such as diamond dressing wheels, internal circular cutting blades, external circular saw blades, wire saw steel sections, and belts saws and wire saws, etc. The cutting disc manufactured by electroplating has good adhesion to the blade steel body, strong holding power to diamond, and can be made very thin, high cutting efficiency, strong wear resistance, and significant economic benefits.
(2) Rolling method: The steel body of the rolling saw blade is a softer low-carbon steel, and a very narrow slot is formed on the periphery of the outer circle. The diamond is coated on the outer circle, then, a steel extrusion wheel is used to squeeze the diamond into the seam and plastically deform the steel body material to firmly embed the diamond. Rolling saw blades are only used for cutting watch gems and processing rare earth ferrites.
(3) Sintering method: The powder sintering method has been the most widely used in the manufacture of diamond saw blades. From traditional cold pressing and sintering saw blades to excellent performance hot pressing and multiple welding saw blades, powder sintering method of manufacturing can be used.
(4) Vacuum brazing method: Vacuum brazing is a relatively method, which is characterized in that there are open long grooves evenly distributed along the circumference of the saw blade body, and the diamond particles with metal composite coating are directly filled by the brazing method. Equipped with long open slots on the circumference of the saw blade base body. The brazing process is currently limited by technology and can only be welded with a single layer of diamond, so the welding area is small, resulting in a short life and large waste of the steel body.
