But also the polishing damage layer does not affect the final observed organization, the organization will not cause false. The former requires the use of coarse abrasive, in order to ensure a greater polishing rate to remove the damaged layer of polish, but also deep polishing damage layer; the latter requires the use of the finest materials, the polishing damage layer shallow, but polishing rate is low. The best way to resolve this contradiction is to polish two stages. The purpose is to remove the polish rough polishing damage layer, this stage should have a maximum rate of polishing machine small beads, rough polishing surface damage is minor considering the formation of beads machine, but should also be as small as possible; followed by fine polishing (or said final polishing), whose purpose is to remove the surface damage produced by rough polishing, the polishing damage is minimized. When polishing machine, grinding and polishing the sample should be absolutely parallel and evenly light pressure on the polishing disc, avoid flying and due to sample too much pressure to produce new wear marks. It should also make the sample rotation and move back and forth along the radial direction of the turntable, to avoid polishing fabric partial wear too fast in the polishing process to continually adding powder suspension, the polishing fabric to maintain a certain humidity. Too large humidity weaken the role of the wear scar polishing, the sample in the hard phase exhibits embossed and non-metallic inclusions in steel and cast iron in the graphite phase to produce 'trailing' phenomenon; when the humidity is too small, due to the friction and heat cause the sample heating, lubrication decreases, grinding machine tarnished small beads, or even spots, will cast light alloy wound surface. In order to achieve the purpose of rough cast, it requires low speed turntable, preferably not more than 600r / min; polishing time should be longer than the time to remove the scratches needed more, because even remove the deformable layer. After rough polishing surface is smooth, but the bleak, uniform under the microscope fine grinding marks, to be fine polishing eliminated. _ Hisayoshi beads mechanical machinery (certified) _ beads machine provided by the Dongguan City for good Machinery Trading Company.
