Composite plating manufacturing method of high-precision irregular grinding wheel

Abstract

The invention discloses a composite plating manufacturing method of a high-precision irregular grinding wheel. The manufacturing method comprises the following steps of preparing of a substrate and abrasives, treating before plating of the abrasives, preparing of a plating solution, treating before plating and preplating of the substrate, mould cavity abrasive grain dispensing, chemical plating thickening, passivating treatment after plating, testing and packing. The manufacturing method has the advantages that the compositely-plated grinding wheel has the characteristic of high profiling, and the consistency of abrasive molding surfaces reaches up to 95% or above; the height uniformity of the abrasives subjected to plating solidification is high, the abrasives can be used for grinding simultaneously to the largest extent, and machining efficiency is improved; and the shape preserving property is good, and the shape of the grinding wheel curve surface almost does not change under the continuous grinding condition, so that the grinding efficiency and the machining precision of the grinding wheel are guaranteed, and the service life of the grinding wheel is prolonged greatly.

Description

technical field [0001] The invention relates to the field of grinding wheels and manufacturing, specifically a high-precision profiling grinding wheel and a manufacturing method, which are mainly used for hydraulic pump stators and rotors, gearbox gears, reducer gears, wind power generation speed increaser gears, and industrial air compressor worms Applications such as profile grinding. Background technique [0002] For the precision grinding of complex processing surfaces, electroplated grinding wheels have unique advantages such as strong bonding force and low porosity compared with bronze abrasive grinding wheels and resin abrasive grinding wheels. However, due to the unequal height of the abrasive and the tip effect during electroplating, it is inevitable to produce some slight deviations during production, which fail to reach the micron level required by the current science; although there is a mature process for electroplating rollers, it is The operation is complex, ...
