Polishing machine, as the name suggests, is to clean up the rough surface of some objects to achieve a mirror effect. The key to the operation of the polisher is to try to get the maximum polishing rate in order to remove the damage layer from the polishing as quickly as possible. Polishing is carried out in two stages. The purpose of rough polishing is to remove the polished damage layer. This stage should have the maximum polishing rate. The surface damage caused by rough polishing is a secondary consideration, but it should be as small as possible. Secondly, fine polishing (or final polishing). Its purpose is to remove surface damage caused by rough polishing and minimize polishing damage. When the polishing machine is polished, the sample grinding surface and the polishing disc should be absolutely parallel and evenly pressed on the polishing disc, taking care to prevent the sample from flying out and creating new wear marks due to too much pressure. At the same time, the sample should be rotated and moved back and forth along the radius of the turntable to avoid local wear of the polishing fabric too fast. During the polishing process, polishing liquid or other polishing aid should be added continuously to keep the polishing fabric at a certain humidity. Too much humidity will weaken the wear scar, so that the hard phase of the sample will appear embossed and the non-metallic inclusions in the steel and the graphite phase in the cast iron will produce a "tailing" phenomenon; if the humidity is too small, the sample will be generated due to frictional heat generation. Heating, lubrication is reduced, the surface is tarnished, and even dark spots appear. Light alloys will scratch the surface and yellowing will appear. After rough polishing, the surface is smooth, but it is dull and dull. Under the microscope, there is a uniform and fine wear scar, which needs to be removed by fine polishing. The speed of the turntable can be appropriately increased during fine polishing, and the polishing time is preferably to throw away the damage layer of the rough throw. After fine polishing, the polished surface is as bright as a mirror, and scratches are not seen under the bright field of the microscope, but the wear marks are still visible under the phase contrast lighting condition. In recent years, a lot of research work has been done on the performance of polishing machines at home and abroad. Many new models and a new generation of polishing equipment have been developed, which have been developed from the original manual operation into various semi-automatic and fully automatic polishing. machine. The performance and features of several commonly used mechanical polishing machines are described below. The polishing machine is specially designed for the surface treatment of steel, aluminum and copper metal products, and dozens of original accessories to meet different needs. It is easy to manufacture snow patterns, drawing patterns, wave patterns and matte with various precisions. Surface, mirror surface, etc., quick repair of deep scratches and slight scratches, rapid grinding and polishing; welds, nozzle marks, trace oxide film, stains and paints, etc., suitable for deburring, forming rounded decorative metal processing, It does not form shadows, transition zones and uneven decorative surfaces during processing, and is an important equipment for the production of metal products. Polishing machine is suitable for the following industries: wood, furniture industry such as flat wood, furniture metal handles and other workpiece sanding; hardware materials and products aluminum profiles and products, stainless steel products and utensils, copper profiles and products, plumbing and sanitary equipment, locks , lighting products, signage nameplates, hardware craft ornaments, knife and scissors, door flaps, car bicycle parts, tableware, shackle products, buttons, belt buckles, mobile phone casings, watch industry and other workpiece sanding; Electronic parts, electronic equipment such as electronic parts, flat sanding. Polishing machine can be used in a wide range of applications, such as mobile phone case, MP3, digital products, notebook computers, PC board drawing, and remarkable effects.
