(1) Select a variety of metal powders that meet the technical conditions and process requirements, and prepare the edge layer carcass powder and the middle layer carcass powder according to a certain proportion of the various metal powders, respectively, according to the corresponding mixing process. Mix evenly, add the matrices that meet the conditions, and perform decontamination and degreasing treatment on the matrices.

(2) Put the concrete road cutting saw blade substrate into the cold-pressed abrasive tool for trial installation. After confirmation, put the edge material layer carcass powder, road cutting chip powder, and middle material layer carcass powder into the mold in turn according to the compression molding process. The pre-pressing operation is carried out in the cavity. Finally, it is sent to a press machine with a specified tonnage for pressing and forming. After pressing and forming, the pressure is relieved and the mold is removed, and the cutting sheet blank is taken out.

(3) Lightly brush a layer of pressure-sensitive adhesive on the cutting saw blade blank, and then sprinkle diamond abrasive grains on the template, so that each hole contains only one diamond, and then cut the road cutting blank with the glue coated The body is placed on the already laid abrasive grain template to make it completely fit, and then the cover plate and the steel plate are placed on the cutting sheet blank in turn, and the press is used to apply force to it, and finally the pressure is released and the steel plate is removed to take out the blank. body, so that the abrasive grains can be arranged on the cutting blade blank in an orderly manner.

(4) Load a plurality of cutting saw blade blanks with arranged diamond abrasive grains into a mold together, and then place them in the overall pressure sintering furnace of the cutting blade for pressure sintering. After the furnace is released, check whether the ordered saw blades are dumb Light, cracks, etc.

(5) Finally, sanding, reaming, painting and cutting should be performed on the orderly arrangement of the road cutting saw blades.
