Production method of reinforced ultra-thin diamond circular saw blade

Abstract

The invention relates to a method for producing a strengthened ultrathin diamond circular saw web. The method comprises the first step of providing a circular saw web base body, wherein the ratio of the thickness of the saw web base body to the diameter of the saw web base body ranges from 0.0020 to 0.0035; the second step of welding a diamond cutting head to the end of the saw web base body according to the laser welding technology; the third step of concentrically arranging strengthened circular saw web bodies on the two sides of the circular saw web base body, wherein the ratio of the diameter of the strengthened circular saw web bodies to the diameter of the saw web base body ranges from 0.24 to 0.45. The strengthened ultrathin diamond circular saw web produced with the production method has the advantages of being narrow in cutting joint, small in number of consumed materials and cutting deviation, neat in cutting edge, good in cutting sharpness and the like and solves the problems that the cutting joint is large, the number of the consumed materials is large, the cutting edge is not neat, and material consumption is large in the ceramic, glass and jade machining process.

Description

technical field

[0001] The invention relates to the technical field of superhard abrasive products, more specifically, the invention relates to a production method of a reinforced ultra-thin diamond circular saw blade for processing non-metallic brittle and hard materials such as glass, jade, pottery and marble. Background technique

[0002] In today's market, diamond circular saw blades have been widely used in the cutting and processing of marble, granite, concrete, asphalt, ceramics, glass, jewelry and jade, semiconductors and other materials, continuously improving product efficiency and reducing material loss, especially in the processing of precious stone, jade and glass When manufacturing products and semiconductor materials, reducing material loss and improving economic benefits are the common pursuit of the market. The diamond circular saw blade is composed of two aspects: the diamond blade and the central substrate of the circular saw blade. The thickness of the ce...
