Manufacturing method of electroplating super-hard abrasive cutting line

Abstract

The invention discloses a manufacturing method of an electroplating super-hard abrasive cutting line. The method comprises an electroless composite plating method of the surface of super-hard abrasive. The surfaces of super-hard abrasive particles are wrapped with a nickel and phosphorus alloy layer through the electroless composite plating method, the nickel and phosphorus alloy layer contains solid particles, and the solid particles are non-conductive particles. The nickel and phosphorus coating containing the solid particles is formed on the surface of the super-hard abrasive through the electroless plating method, the solid particles in the coating are the non-conductive bodies, are doped in the nickel and phosphorus alloy and occupy a certain volume space, the electrical conductivity of the nickel and phosphorus alloy is reduced, the cathode discharge reaction of the surface of the super-hard abrasive depositing on a steel wire in the electro-deposition process is restrained, and accordingly the agglomeration phenomenon of the super-hard abrasive on the cutting line is avoided, the diameter of the cutting line is uniform, removal of the agglomerated super-hard abrasive in the subsequent procedure is not needed, the line diameter is amended, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a method for making an electroplated superabrasive cutting wire. Specifically, it relates to an electroplating superhard abrasive cutting tool, which belongs to the technical field of electroplating. Background technique [0002] Electroplated superabrasive cutting wire refers to a cutting tool formed by using electrodeposition to consolidate superabrasives onto the metal wire substrate through electrodeposited metal. Superabrasives usually refer to diamond abrasives and cubic boron nitride abrasives; electrodeposited metals are usually metallic nickel or nickel alloys; metal wire substrates generally use high-carbon steel wires. Electroplated superabrasive cutting wire is usually used in the cutting process of hard and brittle materials such as silicon crystals, gemstones, and ceramics. [0003] The general manufacturing process of electroplated superabrasive cutting wire is: pretreatment before plating, sanding, thickening ...

AI Technical Summary

Problems solved by technology

The disadvantage of using this kind of metallized superabrasive to manufacture cutting lines by electrodeposition is: due to the greater weight gain of the nickel-phosphorus alloy, the thickness of the nickel-phosphorus alloy layer is relatively large, and the conductivity is good. The superhard abrasive aggregates on the surface of the cutting wire. This agglomeration phenomenon not only causes large fluctuations in the diameter of the cutting wire, but also affects the cutting quality. In addition, it is necessary to use subsequent processes to remove the agglomerated abrasive grains, which not only increases the cost, but also reduces the cutting cost. Line Manufacturing Efficiency

However, the metal layer on the diamond surface used in this method is too thin, and it is easily corroded in the electroplating solution, which affects the continuity of production.
