The working principle of the deburring polishing machine

Pulished:2017-04-11 Number:loading。。。 Source:Suzhou Nuohu

The working principle of the deburring machine is to try to get the maximum polishing rate in order to remove the damage layer that is generated when polished as soon as possible. But also to make the polishing layer does not affect the final observation of the organization, that is, will not cause false tissue. The former requires the use of coarse abrasive to ensure a greater polishing rate to remove the polished damage layer, but the polishing layer is also deep; the latter requires the use of the finest material, so that the polishing layer is lighter, but polished Low rate. The best way to solve this contradiction is to divide the polishing into two stages. Rough cast is to remove the polished damage layer, this stage should have the largest polishing rate, the rough formation of the surface damage is a secondary consideration, but also should be as small as possible; followed by fine throw (or final throw) The purpose is to remove rough surface damage caused by rough throwing, so that polishing damage to a minimum. Polishing machine polishing, the sample grinding and polishing disc should be absolutely parallel and evenly pressed gently on the polishing disc, pay attention to prevent the sample fly out and because the pressure is too large and produce new wear marks. At the same time, the specimen should be rotated and moved back and forth along the radius of the turntable to avoid local wear of the polished fabric. To keep the powder suspension in the polishing process, the polished fabric is kept at a certain humidity. The humidity is too large will weaken the grinding of the grinding effect, so that the hard phase of the sample showing the relief and non-metallic inclusions in the steel and cast iron in the graphite phase to produce "trailing tail" phenomenon; humidity is too small, due to friction heat will make the sample Temperature, lubrication to reduce the grinding surface luster, or even dark spots, light alloy will be wound surface. In order to achieve the purpose of rough throw, requiring the turntable speed is low, it is best not to exceed 600r / min; polishing time should be longer than the time required to remove the scratch, because also remove the deformation layer. Rough grinding after grinding smooth, but dull, in the microscope to observe a uniform and delicate wear marks, to be fine throw to eliminate. The speed of the turntable can be properly raised, polished time to throw away the rough throwing layer is appropriate. Fine grinding after grinding as bright as the mirror, in the microscope under the conditions of the field can not see the scratches, but in the phase contrast lighting conditions can still be seen grinding marks. Polishing machine polishing quality seriously affect the sample structure, has gradually attracted the attention of experts. At home and abroad in the polishing machine performance made a lot of research work, developed a lot of new models, a new generation of polishing equipment, is the original manual operation into a variety of semi-automatic and automatic polishing machine. Here are some of the commonly used mechanical polishing machine performance and characteristics. Casting light specifically for steel, aluminum and other metal products and the surface of the tube for the effect of treatment, dozens of original parts to meet the different needs, easy to create a variety of different precision of the snow pattern, drawing, wavy, matte Face, mirror, etc., fast repair depth scratches and slight scratches, quick grinding and polishing; welds, mouth marks, trace oxide film, stains and paint, etc., apply to deburring, rounded corners, decorative metal processing, In the processing process will not form a shadow, the transition zone and uneven decoration, etc., is an important equipment for the production of metal products. Deburring polishing machine for the following industries: wood, furniture industry, such as flat wood, furniture, metal handle, and other pieces of sanding wire drawing; metal (metal) materials and products aluminum and its products, stainless steel products and utensils, copper profiles and products, Bathroom equipment, locks, lighting products, signs nameplate, metal craft jewelry, knife and scissors, the door of the live leaves, car bicycle parts, tableware category, Ji buckle products, buttons, belt buckle, mobile phone shell, watch industry Workpiece sanding wire drawing; electronic parts, electronic equipment such as electronic parts, flat sanding, such as drawing.
