Centerless grinding wheel for compressor piston machining and forming process thereof

Abstract

The invention discloses a centerless grinding wheel for compressor piston machining. The centerless grinding wheel comprises a base body and an abrasive layer, wherein the abrasive layer is arranged on the base body. The base body is aluminum alloy. The abrasive layer comprises an abrasive, a binder, resin powder, a pore forming agent, a binding agent and a wetting agent. The abrasive is a mixtureof diamond, black silicon carbide and monocrystalline corundum, and the mass ratio of the diamond to the black silicon carbide to the monocrystalline corundum is 1:3:1.5; the binder is a ceramic binder; the resin powder is imine resin powder; the wetting agent is a mixture of methylphenol and polyvinyl alcohol, and the volume ratio of the methylphenol to the polyvinyl alcohol is 1:2; the pore forming agent is a mixture of hollow alumina balls and graphite particles, and the mass ratio of the hollow alumina balls to the graphite particles is 3:1. The invention further discloses a forming process of the centerless grinding wheel for compressor piston machining. The forming process is simple and practicable, the formed centerless grinding wheel is resistant to high temperature, and a compressor piston with high precision can be machined.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a centerless grinding wheel for processing a compressor piston and a forming process thereof. Background technique [0002] During the normal operation of the compressor, the installation groove for installing the scribe on the piston is relatively sliding and sealed with the tip of the scribe, so the accuracy of the installation groove is required to be high. In the related technology, due to the unbalanced cutting force, the non-complete circle cannot be drilled. Hole or reaming processing; [0003] The grinding wheel is a bonded abrasive that consolidates ordinary abrasives into a certain shape (mostly round, with a through hole in the center) and has a certain strength. It is generally composed of abrasives, bonds and pores. These three parts are often The three elements called bonded abrasives are classified according to different binders. The common ones are ceramic (bond) grinding whee...
