Problems solved by technology

[0004] The purpose of the present invention is to solve the existing viscoelastic abrasives used for abrasive finishing, which have poor fusion between abrasive grains and carrier medium, easy adhesion of abrasive grains to workpieces, and poor high temperature resistance, resulting in difficult finishing quality. To meet the technical indicators, especially for the problem that the finishing effect on the surface of difficult-to-machine materials is worse, a viscoelastic fluid soft abrasive for abrasive streamlining on the surface of difficult-to-machine materials is invented

Abstract

A viscoelastic fluid soft abrasive material for abrasive particle flow finishing processing of the surface of a difficult-to-process material is suitable for finishing processing of the surface of the difficult-to-process material such as nickel-based superalloy, titanium alloy, stainless steel and the like, and is characterized in that the viscoelastic fluid soft abrasive material takes 20-25% by mass of methyl vinyl silicone rubber as a carrier medium, and 5-10% by mass of alkyl silicone oil, 10-15% by mass of white oil, 2-5% by mass of dimethyl silicone oil, 2-7% by mass of paraffin, 1-3% by mass of sodium stearate and 35-60% by mass of grinding particles are added into the carrier medium. The abrasive material is good in viscoelasticity, good in fluidity, good in integration of abrasive particles and the carrier medium, free of adhesion of the abrasive particles to a workpiece, good in high temperature resistance and good in finishing quality.

Description

technical field [0001] The invention relates to the field of surface finishing of difficult-to-machine materials, in particular to an abrasive technology for surface-processing difficult-to-machine materials such as nickel-based superalloys, titanium alloys, and stainless steel, and specifically to an abrasive streamer for the surface of difficult-to-machine materials. Processed viscoelastic fluid soft abrasives. Background technique [0002] Abrasive flow machining is a special finishing method that uses viscoelastic abrasives to process workpieces (the cutting edge of fluid abrasives produces fine cutting and finishing on the processed surface), which can well polish various metal materials and hard non-metals Irregular shaped surfaces, special-shaped curved surfaces, narrow slits, micropores, intersecting channels, etc. of material parts can reduce the original surface roughness by 1 to 2 grades in one process, and can complete rounding, deburring and polishing at the sam...
