Polishing machine detailed introduction Applicable industries and application scope

The polishing machine, as the name suggests, is to clean the rough parts of the surface of some objects to achieve a mirror effect. The key to the operation of the polishing machine is to try to get the maximum polishing rate in order to remove the damaged layer generated during polishing as soon 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; the second is fine polishing (or final polishing). Its purpose is to remove surface damage caused by rough polishing and minimize polishing damage.

When polishing by the polishing machine, the grinding surface of the sample and the polishing disk should be absolutely parallel and lightly pressed on the polishing disk evenly. Take care to prevent the sample from flying out and creating new wear marks due to excessive pressure. At the same time, the sample should be rotated and moved back and forth along the radius of the turntable to avoid local abrasion of the polishing fabric too fast. During the polishing process, polishing liquid or other polishing aids should be added continuously to keep the polishing fabric at a certain humidity. Too much humidity will weaken the effect of polishing wear marks, causing the hard phase of the sample to appear embossed and non-metallic inclusions in steel and graphite phase in cast iron to cause tailing; when humidity is too low, friction heat will cause the sample to heat up. The lubrication effect is reduced, the grinding surface loses its luster, and even black spots appear. The light alloy will damage the surface and cause yellowing.

After rough polishing, the grinding surface is smooth, but dull and dull. There are even and fine wear scars observed under the microscope, which need to be eliminated by fine polishing. The speed of the turntable can be appropriately increased during the fine polishing, and the polishing time is appropriate to throw away the damaged layer of the rough polishing. After fine polishing, the polished surface is bright as a mirror, and no scratches can be seen under the bright field of the microscope, but the wear marks are still visible under the phase contrast illumination.

In recent years, a lot of research work has been done on the performance of polishing machines at home and abroad, and many new models and new generations of polishing equipment have been developed. The original manual operation is developing into a variety of semi-automatic and Fully automatic polishing machine. The following describes the performance and characteristics of several commonly used mechanical polishing machines. The polishing machine is specially designed for the effect treatment of the surface and pipes of metal products such as steel, aluminum and copper. Dozens of original accessories meet different needs, and it is easy to create a variety of snow patterns, brushed patterns, wave patterns, and matte with different precision. Surface, mirror surface, etc., fast repair of deep scratches and slight scratches, fast grinding and polishing; welds, nozzle marks, trace oxide films, stains and paint, etc., suitable for deburring, forming rounded decorative metal processing, in During the processing, there will be no shadows, transition zones and uneven decorative surfaces. It is an important equipment for the production of metal products.

The polishing machine is suitable for the following industries: wood and furniture industries such as flat wood, furniture metal handles and other workpieces sanding and wire drawing; hardware materials and products, aluminum profiles and their products, stainless steel products and utensils, copper profiles and products, plumbing and sanitary equipment , Locks, lighting products, signs and nameplates, hardware crafts accessories, knives and scissors, door flaps, auto and bicycle parts, tableware, buckle products, buttons, belt buckles, mobile phone shells, watch industry, etc. Light drawing; electronic parts, electronic equipment such as electronic parts, flat sanding and drawing.

The polishing machine has a wide range of applications, which can be used for mobile phone shells, MP3, digital products, notebook computers, PC boards, and the effect is remarkable.
