Polishing machine polishing of the key is to try to get the maximum rate inorder to get rid of damaged layer produced by Polish as soon as possible. Whilealso making the Polish organization observed does not affect final damage layer,which does not result in a bogus organization. Coarse abrasive is required theformer, in order to ensure greater damage to remove Polish polishing rate, butpolished deep damage layer, whereas the latter requires the use of the finestmaterials and makes polished lighter damage layer, but polishing rate low.
The best way to solve this problem is to make polishing is divided into twophases. Rough cast aimed at removing grinding damage layer, this stage shouldhave a maximum polishing rate, formation of rough cast surface damage is asecondary consideration, but should also be as small as possible, followed by the precision throw (or throw), the purpose of which is the removal of roughcast surface damage of so polished to minimize damage. Polishing machinepolishing, grinding and polishing test specimens should be absolutely parallellight evenly on the pad, avoid flying out of the sample and the new wear causedby too much pressure. Should also move back and forth along the wheel RADIUS anddirection of rotation of the sample, in order to avoid polishing fabric wear tooquickly in the polishing process to keep adding powder suspensions, keepspolishing fabric humidity. Humidity too much reduces the wear of polishing, hardphases in the sample rendering embossed and non-metallic inclusions in steel andcast iron graphite phase in the "trailing" phenomenon; humidity too small due tofrictional heating causes the sample to heat up, decrease lubrication, buffedand dull, even black spots, light alloy will become damaging surfaces. In order to achieve the purpose of rough cast, requiring lower rotary speed, preferablynot more than 600r/min; polishing time should be longer than the time requiredto remove scratches, as also to take out deformed layer. Buffed smooth after therough cast, however bleak, under the microscope even carefully rubbed, fine finishing eradication.
Turntable speed can be increased when fine polishing, polishing time to throwaway the damaged layer of rough cast is appropriate. Fine polishing grinding thebright as a mirror, under the brightfield microscope can't see the scratches,but can still be seen in phase-contrast lighting conditions to wear. Polishingmachine polishing the quality of seriously affecting the organizationalstructure of the sample, has gradually attracted the attention of experts.Polishing machine at home and abroad ' performance did a lot of research work,research and a lot of new models, the new generation of polishing equipment, isdeveloped from a manual operation of all kinds of semi-automatic and fully automatic polishing machine.
Here are some commonly used machine polishing machine performance and features.Throwing machine light specifically for steel, and aluminum copper, metal products of surface and tube class for effect processing, dozens of species original accessories meet different needs, easy manufacturing out various precision different of snowflake lines, and drawing lines, and wave lines, and dumb smooth, and mirror,, fast patch depth designated marks and minor scraping spent, fast polished and polishing; weld, and water mouth marks, and traces oxidation film, and stains and paint,, applies in to Burr, and formed round angle, decorative sex metal processing, in processing process in the does not formed shadow, and transition Strip and decorative surface not uniform,, Isimportant for metal products production line equipment. Polishing machine applies yú following industry: wood, and furniture industry as flat wood, and furniture metal handles, artifacts sand light drawing; hardware (metal) material and the products aluminum profiles and products, and stainless steel products and the vessels, and copper profiles and the products, and plumbing bathroom equipment, and lock class, and lighting products, and signs nameplate, and hardware process jewelry, and knife cut class, and door of live leaves, and car bike spare parts, and tableware class, and right buckle class products, and buttons, and belt buckle, and phone shell, and clocks industry, artifacts sand light drawing; electronic parts, and electronic equipment as electronic parts, and Flat sanding wire drawing and so on.
