Abstract

The invention relates to a dry and wet dual-purpose laser welding diamond saw blade, and belongs to the technical field of diamond processing tools. The diamond saw blade comprises a circular base body which comprises a side circumferential surface located on the edge. A plurality of chip removal grooves extending in the circle center direction inwards are formed in the side circumferential surface at intervals. Diamond tool bits are formed between the chip removal grooves. The chip removal grooves include the first chip removal grooves and the second chip removal grooves, wherein the first chip removal grooves and the second chip removal grooves are formed at intervals. The diamond tool bits include the first diamond tool bits and the second diamond tool bits, wherein the first diamond tool bits and the second diamond tool bits are arranged at intervals. The cross sections of the first chip removal grooves are larger than those of the second chip removal grooves. The surfaces of the first diamond tool bits are planes. A plurality of protruding strips are arranged on the surfaces of the second diamond tool bits. Grooves are formed between the protruding strips. Chip removal and heat dissipation can be well conducted through the diamond saw blade in the cutting process, the good cutting performance can be kept under the condition of no cooling water grinding, and the purpose of conducting processing under extreme conditions is achieved for users.

Description

technical field [0001] The invention relates to the technical field of diamond processing tools, more specifically, the invention relates to a laser welding diamond saw blade for wet and dry use. Background technique [0002] In today's market, diamond 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 products When it comes to semiconductor materials, reducing material loss and improving economic benefits are the common pursuit of the market. The diamond saw blade is composed of two aspects: the diamond blade and the central substrate of the circular saw blade. The thickness of the central substrate of the circular saw blade determines the thickness of the diamond blade. The larger the size, the worse the economic benefit,...
