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

Embodiment 1

[0021] Such as Figure 1-2 shown.

[0022] First, 20 kg of SiC abrasive grains with an average particle diameter of 30 mesh, 10 kg of SiC abrasive grains with an average particle diameter of 60 mesh, and 10 kg of SiC abrasive grains with an average particle diameter of 500 mesh were selected from the market. Next, use long carbon chain C8-C14 modified silane to carry out lipophilic treatment on its surface, mix well and add 25kg of carrier medium methyl vinyl silicone rubber. Then, add 10kg of alkyl silicone oil (which can effectively increase the wear resistance and temperature resistance of the abrasive), 15kg of white oil (softener, used to adjust the viscoelasticity and hardness of the abrasive), and 5kg of dimethyl Base silicone oil (lubricant, increase the lubrication performance of the abrasive), 2kg of paraffin wax (lubricant, increase the lubrication performance of the abrasive), 3kg of sodium stearate (heat stabilizer, increase the thermal stability of the abrasive)...

Embodiment 2

[0025] First of all, 30 kg of diamond abrasive grains with an average particle diameter of 20 mesh, 15 kg of diamond abrasive grains with an average particle diameter of 50 mesh and 15 kg of diamond abrasive grains with an average particle diameter of 300 mesh were selected. Next, use long carbon chain C8-C14 modified silane to do lipophilic treatment on the surface, mix well and add 20kg of carrier medium methyl vinyl silicone rubber. Then, add 5kg of alkyl silicone oil (which can effectively increase the wear resistance and temperature resistance of the abrasive), 10kg of white oil (softener, used to adjust the viscoelasticity and hardness of the abrasive), 2kg of dimethyl Base silicone oil (lubricant, increase the lubrication performance of the abrasive), 2kg of paraffin wax (lubricant, increase the lubrication performance of the abrasive), 1kg of sodium stearate (heat stabilizer, increase the thermal stability of the abrasive). Finally, it can be configured into 100kg visc...

Embodiment 3

[0027] First, choose 22 kg of cubic boron nitride (CBN) with an average particle diameter of 25 mesh, 11.5 kg of cubic boron nitride (CBN) with an average particle diameter of 55 mesh and 11.5 kg of cubic boron nitride (CBN) with an average particle diameter of 400 mesh. kg. Next, use long carbon chain C8-C14 modified silane to carry out lipophilic treatment on its surface, mix well and add 22kg of carrier medium methyl vinyl silicone rubber. Then, add 8kg of alkyl silicone oil (which can effectively increase the wear resistance and temperature resistance of the abrasive), 13kg of white oil (softener, used to adjust the viscoelasticity and hardness of the abrasive), and 3kg of dimethyl Base silicone oil (lubricant, increase the lubrication performance of abrasives), 7kg of paraffin wax (lubricant, increase the lubrication performance of abrasives), 2kg of sodium stearate (heat stabilizer, increase the thermal stability of abrasives). Finally, it can be configured into 100kg v...

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...
