Key polishing machine operation is to try to get the maximum polishing rate, so as to remove the damaged layer generated during grinding as soon as possible. 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 polishing rate, the formation of rough polishing surface damage is a secondary consideration, but should also be as small as possible; followed by the fine cast (or final polishing). Its 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 with slight pressure on the beads polishing machine manufacturers, 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 and dull, and 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. Saw Woodworking how data noise reduction: To reduce mechanical noise Muzhu chi, domestic and foreign departments have done a lot of research NC beads machine, because its noise generated in depth investigation and analysis, and has taken many appropriate lower Measures of noise, to make high-quality low-voice sound woodworking machinery emerging. Up to now beads machine, lower back Saw woodworking planer and noise have made great progress in reducing idling noise can reach 70dB (A) about the load status 82 dB (A) level of around. However, due to the load state, the influence of the noise of factors, such as the processing of wood species, size, hardness, texture, spindle speed and feed rate, etc., have a direct impact on the size of the noise, so noise assessment load is difficult unified control appears more difficult. To control woodworking machinery noise, we have to grasp these types of noise, frequency, voice sound source Li in, their causes and their impact factor to flexibly apply noise control theory and methods, effective noise reduction measures.
