Embodiment Construction

[0032] Such as figure 1 As shown, grooves at equal intervals are processed on the edge of the saw blade base 1 with a pitch of 5 to 20 mm. The diamond brazing base 3 brazed with diamond particles is inserted and welded into the grooves of the saw blade base 1 to The orderly arrangement of the diamond particles 2 in the circumferential direction of the saw blade is realized.

[0033] The saw blade structure mainly includes four parts: saw blade base 1 , diamond particles 2 , diamond brazing base 3 and self-lubricating filler 4 . First arrange the diamond particles in an orderly manner on the diamond brazing substrate, evenly sprinkle a layer of Ag-Cu-Ti alloy, put it into a vacuum furnace for brazing, the heating temperature is 900 ° C ~ 1100 ° C, and the holding time is 4 ~ 20 minutes , vacuum degree 1×10 -1 ~1×10 -3 Pa, cooled to room temperature with the furnace. Then, the diamond brazing matrix with welded diamond particles is welded on the saw blade matrix at equal int...

Abstract

The invention belongs to the field of processing tools for stones and ceramics, and particularly relates to a self-lubricating diamond circular saw web. The circular saw web comprises a saw web base body, a diamond braze-welding base body which is brake-welded with diamond particles, and self-lubricating filler, wherein grooves are processed in the edge of the saw web base body at equal spacing; the diamond braze-welding base body is partially inserted into the grooves of the saw web base body for being fixed; the diamond braze-welding base body is partially exposed to the surface of the saw web base body; and the self-lubricating filler is filled in the exposed diamond braze-welding base body, so that the peripheral surface of the circular saw web is smooth and complete. A single-layer braze-welding diamond technology, an abrasive particle orderly arranging technology and a solid lubricating technology are applied to a manufacturing process of the diamond saw web, so that firm holdingof abrasive particles can be realized, and using efficiency of the abrasive particles can be improved; and meanwhile, diamond can be prevented from generating graphitization at a high temperature, and a plurality of problems in the using process of the diamond saw web can be effectively solved, so that using performance of the diamond saw web is improved.

Description

technical field [0001] The invention belongs to the field of processing tools for stone and ceramics, in particular to a self-lubricating diamond circular saw blade. Background technique [0002] Stone processing is an industry that consumes the most diamonds, accounting for about 70%-80% of the total. As a commonly used stone processing tool, diamond circular saw blades mainly include two types: electroplated saw blades and multi-layer head welded saw blades. Their common disadvantage is that the diamond particles are only mechanically inlaid on the matrix, and they are arranged in disorder. The mechanical inlay force has little holding force on the abrasive grains, and the abrasive grains are easy to fall off under the action of impact force; and the disordered abrasive grains Arrangement will result in abrasive grains being either wasted due to redundancy, or crushed due to overload. In addition, due to the large amount of heat generated by processing, the temperature o...
