Electroplated diamond wire saw products is a linear sawing tool made by adding a certain diamond abrasive to the plating solution. When the metal ions in the plating solution are reduced to metal at the cathode and deposited on the wire saw substrate, the diamond abrasive particles are wrapped in the coating. The utility model effectively overcomes the disadvantages of low hol force of resin wire abrasive, easy falling off, low mechanical strength and easy fracture of brazed diamond wire saw, and has stronger practicability. The cutting process has the advantages of smooth section, high yield, high cutting efficiency, energy saving andingd not limited by material size and shape. It is especially suitable for the processing of precious hard and brittle materials such as gemstones.

The preparation process of electroplated diamond wire saw products includes: pretreatment, pre plating, sanding, thickening, post-treatment and other procedures, and each process has different effects on the production efficiency and service performance of wire saw. The research shows that the time required for the two processes can be shortened and the production efficiency can be improved by placing the brush plating device in the pre plating and thickening tank. Based on the basic theory of composite electroplating, the process parameters affecting sanding were studied. The results show that the sand loading speed can be more than doubled and the production efficiency can be improved by replacing ordinary diamond particles with coated diamond particles. In order to better study the performance of wire saw, the sawing trajectory equation can be established through cutting experiment, superposition principle and trajectory curve calculation, which provides a theoretical basis for optimizing the cutting process parameters of diamond wire saw products. It is found that when the process parameters are certain, the elastic modulus distribution of the materials on both sides of the notch is symmetrical about the cutting direction of the wire saw, which can effectively improve the surface quality of the wafer; The cutting direction of the wire saw is consistent with the easy cracking direction in the crystal plane, which can effectively inhibit the breakage of the wafer surface. In order to further improve the performance of wire saw, bright plating solution can improve the performance of electroplated diamond wire saw, and the best production process is designed according to the influence of time and current density on the coating. A three wire stranded electroplated diamond wire saw with stranded steel wire core is prepared. It is found that the three wire stranded electroplated diamond wire saw has the advantages of small wear and strong cutting ability.

In order to adapt to some machining processes, a new type of ring electroplated diamond wire saw is developed. Its substrate is made of 65Mn steel wire with a diameter of 0.8mm, and the interfaces at both ends of the substrate are welded by argon arc welding. It is especially suitable for sawing precious hard and brittle materials such as monocrystalline silicon and gemstones and anisotropic composites. It can also sawing two-dimensional curved surfaces. The experiments show the excellent characteristics of ring diamond wire saw. The surface roughness of monocrystalline silicon is between 0.328-0.6 μ M; The surface roughness of Cut Sapphire is between 0.473-0.7 μ m, which has good cutting effect. The experiment of sawing Shidao red granite with a self-made ring electroplated diamond wire saw shows that increasing the diamond particle size can not greatly improve the cutting efficiency, but the feed pressure and wire speed of the wire saw have a great influence on the cutting efficiency. Their increase can improve the cutting efficiency, but the most favorable thing is to improve the wire speed of the wire saw. A circular saw awesome sawing machine was designed and manufactured to improve the wire speed. The circular wire saw can be continuously moved in a single direction, with a speed range of 4.5 to 28m/s. It can meet the cutting requirements of different materials, and can realize the two feed modes of stepless speed servo motor drive and constant feed drive. Through the research, it is considered that while improving the accuracy of wire saw machine tool and fully reflecting the advantages of higher machining efficiency and better machining quality, longer annular consolidated diamond saw wire should also be designed and manufactured to meet the requirements of cutting hard superhard materials. Due to the limitation of welding process and welder function, piano wire with diameter less than 0.2mm and materials with high carbon content can not be welded. Therefore, it is necessary to further study new welding process methods and post weld heat treatment technology.

Although the performance of electroplated diamond wire saw is not as good as resin wire and brazing wire in production efficiency and abrasive holding force, the overall performance of the former is better than the latter two, and the application range is wider. Electroplated diamond wire saw has better improved its performance through the improvement of production process, wire speed, three wire stranding, ring wire and so on. However, in order to further improve its performance, more in-depth research should be done in the future work, continue to study more reasonable production process, improve the production efficiency of wire saw, reduce production cost, improve the holding force of binder on abrasive particles and prolong service life. At the same time, the accuracy of sawing equipment should be improved and the sawing quality should be optimized.
