Description

A kind of water jet polishing process
Technical field
The present invention relates to piece surface pre-treatment field, particularly a kind of be used to removing piece surface processing clout and polishing, improve the water jet polishing process of part wearability.
Background technology
At present, the part polishing processing method has air grinding, abrasive Flow polishing, the precise and tiny polishing of abrasive jet both at home and abroad:
1. air grinds: principle is to push the effect that the abrasive particle ball that contains abrasive material slips over or the striking work generation is ground by gas pressure, but the burr removing chamfer polishing, shortcoming is that equipment cost is high, and operation cost is high, and efficient is low, not can be mass;
2. abrasive Flow polishing: principle is to push the soft flow that contains abrasive material by pressure to produce the effect of grinding through workpiece, but the burr removing chamfer polishing, and shortcoming is that equipment cost is high;
3. the precise and tiny polishing of abrasive jet: principle is to push the effect that the generation of lapping liquid striking work is ground by gas pressure, but the burr removing chamfer polishing, and shortcoming is that abrasive material easily embeds surface of the work, forms the surface sclerosis, is unfavorable for the following process processing.
Application number is the invention of CN200810155515.3, a kind of gas polishing process method of micropores of shaft class parts is disclosed, it adopts gases at high pressure as the polish pressure source, selecting the 0.1mm steel ball is polish abrasive, micropore to the need polishing passes into the gases at high pressure that can produce turbulent flow in micropore, thereby finishes the polishing to micropores of shaft class parts.The method belongs to the air polishing, still exists equipment cost high, and operation cost is high, and efficient is low, the defective that not can be mass.
Summary of the invention
The object of the invention is to solve the defective that existing air grinds, abrasive Flow is polished, the precise and tiny finishing method of abrasive jet exists in part polishing is processed, a kind of water jet polishing process is provided, it pushes the lapping liquid bump or slips over workpiece by gas pressure and produces the effect of grinding, but deburring, chamfering and polishing, and can not cause the damage of part, equipment cost is low, operation cost is low, efficient is high, can be mass, abrasive material can not form the surface of the work sclerosis, can not produce harmful effect to follow-up processing.
Another object of the present invention is to a kind of water jet polishing process white fused alumina lapping liquid.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water jet polishing process, simultaneously a plurality of essences are rushed in capable ash propel polish with white fused alumina lapping liquid A by the water blasting craft first, essence after simultaneously white fused alumina lapping liquid A being processed by the water blasting craft with white fused alumina lapping liquid B is again rushed in capable ash propel polish, described white fused alumina lapping liquid A is by 7.5 ~ 8.7 parts in water, 0.8 ~ 2 part of white fused alumina, 0.3 ~ 0.7 part of proportioning of aqueous rust preventive forms, described white fused alumina lapping liquid B is by 6.3 ~ 8.5 parts in water, 1 ~ 3 part of white fused alumina, 0.03 ~ 0.2 part of thickener, 0.3 ~ 0.7 part of proportioning of aqueous rust preventive forms, and above-described each composition all by weight.
Mentality of designing of the present invention is, with white fused alumina lapping liquid A essence is rushed in capable ash propel polish first, then with white fused alumina lapping liquid B essence is rushed in capable ash propel polish again, the equipment that uses mainly is the water sand-blasting machine, equipment cost is low, operation cost is low, and white fused alumina lapping liquid A rushes in capable ash propel polish to essence and is used for the deburring of part chamfering, except the processing clout; White fused alumina lapping liquid B rushes in capable ash propel polish to essence and is used for part polishing, reduce friction factor, improve the adhesion of vacuum coating, improve the wearability of part, prolong part service life, while is injuring part not, behind the ash propel polish, abrasive material can not form the surface of the work sclerosis, can not produce harmful effect to follow-up processing, ash propel polish can be rushed in row to a plurality of essences simultaneously, can be mass.
