Efficient grooving resin wheel for preventing workpiece from being burnt and application thereof

Abstract

The invention discloses an efficient grooving resin wheel for preventing a workpiece from being burnt and application of the efficient grooving resin wheel. The efficient grooving resin wheel aims to solve the problems, such as workpiece burning, low grinding efficiency, a short maintaining period and incapability in reutilization of waste products, prone to occurrence in the grinding and grooving process of plunger products of a precise oil atomizer. The efficient grooving resin wheel is composed of a base body and a working abrasive layer. The efficient grooving resin wheel is characterized in that the working abrasive layer is made of a resin binder and mixed padding, wherein the resin binder is superfine phenolic resin; the mixed padding comprises, according to the volume ratio, 10-20 percent of superfine WA with the grain diameter ranging from 10 microns to 20 microns, 5-10 percent of nanoscale SiO2 with the grain diameter ranging from 0.03 micron to 0.05 micron, 5-15 percent of superfine Cu with the grain diameter ranging from 0.5 micron to 1.0 micron, 1-10 percent of nanoscale TiO2 with the grain diameter ranging from 0.03 micron to 0.05 micron, 1-3 percent of FeS, 1-10 percent of polycrystalline diamond and 15-30 percent of CBN. The efficient grooving resin wheel has the advantages that grinding efficiency is high, and the cutting edge is sharp; the shape of the efficient grooving resin wheel is well kept, the maintenance period is long, and the service life is long; the workpiece which is ground is high in accuracy, and the dimensional accuracy is not higher than 0.002 mm; the workpiece is not burned, and therefore the waste products caused by burning are eliminated.

Description

technical field [0001] The invention relates to the field of precision machining, in particular to a resin grinding wheel for grooving precision mechanical workpieces, more specifically to a high-efficiency grooving resin CBN grinding wheel applied to precision fuel injector plunger products. Background technique [0002] With the precision and industrialization of the machining industry, improving production and processing efficiency is undoubtedly one of the most effective ways to save costs. The plunger used for precision injectors is one of the core workpieces of the equipment. The groove of the plunger has the characteristics of large grinding depth, high precision requirements, and easy burns, especially the problem of burns. Burns on the workpiece are waste products and cannot be used. The secondary processing is repeated and reused. Therefore, in the actual production of this type of workpiece, the processing efficiency is low, which is a difficult processing procedu...

Problems solved by technology

The plunger used for precision injectors is one of the core workpieces of the equipment. The plunger groove has the characteristics of large grinding depth, high precision requirements, and easy burns, especially the problem of burns. Burns on the workpiece are waste products and cannot be used. Reuse of secondary processing. Therefore, in actual production, the processing efficiency of this type of workpiece is low, which is a difficult processing procedure and affects the overall production efficiency.

[0003] At present, domestic grinding wheels for grooving are mainly divided into domestic and imported. Domestic grinding wheels generally have low processing efficiency, are prone to burns, and have a short dressing cycle; imported grinding wheels have high processing efficiency, no burns, and long dressing cycles. long-term use
