Problems solved by technology

[0003] At present, most of the beads are mainly made of diamond materials. Diamond is mainly used in the processing of hard and brittle materials such as cemented carbide, glass, ceramics, stone, concrete, and building materials. Because diamond has an obvious affinity for iron and carbon at high temperatures, it can be used in diamond When the wire saw cuts iron materials at high speed, the high temperature generated will easily graphitize the diamond and form iron carbides, causing the diamond to lose its cutting ability, which will cause the wire saw to wear quickly, affecting the sharpness, cutting effect and service life. , so the diamond wire saw is not suitable for cutting metal materials such as steel

Abstract

The invention discloses a diamond rope saw bead added with cubic boron nitride. The diamond rope saw bead is prepared from metal powder, diamond, cubic boron nitride and the like, wherein the metal powder comprises FeCu30 pre-alloyed powder, FeCu20 pre-alloyed powder, CuSn15 pre-alloyed powder, am1 alloy powder, cobalt powder and tungsten carbide powder. The mode of coating diamond and cubic boronnitride with a covering agent and then blending the coated body with the metal powder is adopted for adding of the cubic boron nitride. The obtained diamond rope saw bead not only has the property advantages of being good in abrasive resistance, high in toughness, high in heat stability and the like, the service life of a diamond rope saw is greatly prolonged, the cutting hardness of the diamondrope saw is greatly improved, and the cutting speed of the diamond rope saw is greatly increased. In addition, according to a preparation process of the diamond rope saw, the special coating process is adopted for coating the diamond and cubic boron nitride to form a composite, and then the composite is blended with the metal powder and treatment conditions are limited, so that the high quality and high performance of the diamond rope saw are guaranteed. The preparation process is convenient, safe, high in production efficiency and low, and the products are excellent and stable in quality.

Description

technical field [0001] The invention relates to the technical field of diamond wire saws, in particular to a diamond wire saw bead added with cubic boron nitride and a preparation process of the diamond wire saw. Background technique [0002] Diamond wire saw is a tool for cutting various hard materials, mainly used in stone mining, block shaping, concrete, plate cutting and forming cutting processing; and beading is an important part of diamond wire saw. The component is a cutting body with a steel wire rope as a carrier. [0003] At present, most of the beads are mainly made of diamond materials. Diamond is mainly used in the processing of hard and brittle materials such as cemented carbide, glass, ceramics, stone, concrete, and building materials. Because diamond has an obvious affinity for iron and carbon at high temperatures, it can be used in diamond When the wire saw cuts iron materials at high speed, the high temperature generated will easily graphitize the diamond ...
