Polishing machine works

The key to the operation of the polishing machine is to try to get the maximum polishing rate, as soon as possible to remove the damaged layer generated when polished. But also polishing damage layer does not affect the organization of the final observed that will not cause a false organization. The former requires the use of coarse abrasive, in order to ensure that the polished to remove the damaged layer has a larger polishing rate, but also deep polishing damage layer; the latter requires the use of the finest materials, polishing damage layer shallower, but polished The rate is low.

    The best way to resolve this conflict polishing is divided into two phases. The rough polishing purpose is to remove polishing damage layer, this stage should have a maximum rate of polishing, the formed rough polishing surface damage is a secondary consideration, but also should be as small as possible; followed by fine polishing (or final polishing) Its purpose is to remove the rough polishing the surface damage, polishing minimize the damage. Polisher, sample grinding and polishing discs should be absolutely parallel and evenly with slight pressure on the polishing disc to be taken to prevent the sample fly out and too much pressure on the new wear scar. It should also enable the rotation of the sample and to move back and forth along the radius direction of the turntable, in order to avoid partial wear of the polishing fabric too fast in the polishing process to continually adding the micronized suspension, so that the polishing fabric to maintain a certain humidity. Humidity too weakened the wear scar role polished, hard phase present in the sample the embossed and steel non-metallic inclusions and cast iron in graphite to produce the phenomenon of "trailing"; when the humidity is too small, due to the friction and heat causes the sample warming, lubrication decreases, grinding lose their luster, or even dark spots, light alloy surface is throwing injuries. In order to achieve the purpose of rough polishing require lower speed dial, preferably not more than 600r/min; polishing time should be longer than the time required to remove the scratches, but also to remove the deformation layer. Rough polishing grinding smooth, but dull, uniform and meticulous wear scar observed under the microscope, be eliminate by fine polishing.


    The fine polishing when the turntable speed may be appropriate to improve the polishing time to throw away the rough polishing damage layer is appropriate. Fine polishing after grinding surface bright as a mirror, can not see the scratches in the bright field microscope conditions, but in the phase-contrast lighting conditions you can still see the wear scar. The quality of the polishing machine polishing serious impact on the organizational structure of the sample, has gradually attracted the attention of experts. At home and abroad in the performance of the polishing machine made a lot of research and come up with a lot of new models, a new generation of polishing equipment, from manual operation is developed into a wide variety of semi-automatic and automatic polishing machine.

    The following describes the properties and characteristics of several commonly used mechanical polishing machine. Polishing machine light specifically for steel, aluminum, copper and other metal products, surface and Tube effects processing, dozens of original accessories to meet different needs, and easily create a variety of different accuracy snow pattern, drawing lines, wavy lines, matt surface, mirror, rapid repair deep scratches and minor scratches, fast grinding and polishing; weld outlet marks, trace oxide film, stains and paints, suitable for deburring, formed a rounded decorative metal processing, in the process does not form Shadow, transition zone and decorative surface uneven, metal products production line equipment. Polishing machine is suitable for the following industries: wood, furniture industry, such as flat wood, furniture, metal handle workpiece sanding drawing; hardware (metal) materials and products, aluminum products, stainless steel products and utensils, copper profiles and products, plumbing and sanitary equipment , locks, lighting products, signs nameplate, metal craft jewelry, knives, scissors, door flap, car bicycle parts and accessories, tableware, the condemnation buckle type products, buttons, belt buckles, cell phone case, watch industry and other parts of sand The light drawing; electronic components, electronic equipment such as electronic parts, flat sanding drawing.
