    How to use polishing machine to get the best results?
    Automatic polishing machine operation is relatively simple, just need to put the workpiece on fixture, and then fixture fixed on the automatic polishing machine workstation. Then start the automatic polishing machine, set the polishing time, when the time arrived, the polishing  automatically stopped, then remove the workpiece from worktable. Before start automatic polishing machine, we need to adjust the distance between the polishing head and the working surface. In order to achieve the best contact effect, 
    
    During the polishing process, manual wax can be used to reduce the cost of polishing. A polishing machine is composed of a base, a throw, a polished fabric, a polishing cover and a cover. The motor is fixed on the base, and the conical sleeve fixed to the polishing disc is connected with the motor shaft through screws. The polished fabric is fastened on the polishing disc by a ring. After the motor is started by a switch on the base, the sample can be pressed by hand to polish on the rotating polishing disc. The polishing fluid added during the polishing process can be flowed into the square plate beside the polishing machine through a drain pipe fixed in the plastic plate on the base. The polishing cover and cover can prevent lime and soil and other sundries from falling on the polished fabric when the machine is not in use and affect the use effect.
    
    polishing machine operation is to try to get the maximum polishing speed, so as to remove the damage layer caused by polishing as soon as possible. At the same time, polishing damage layer will not affect the final observed tissue, that is, no false tissue will be created. The former requires the use of coarse abrasive to ensure a greater polishing rate to remove the polished damage layer, but the polishing damage layer is also deeper; the latter requires the use of the finest material, so that the polishing damage layer is shallow, but the polishing rate is low. The best way to solve this contradiction is to divide polishing into two stages: rough casting and fine polishing. Coarse polishing is to remove the polishing damage layer, which should have the maximum polishing speed at this stage. Coarse polishing surface damage is a secondary consideration, but should also be as small as possible; followed by fine polishing (or final polishing), the purpose is to remove the surface damage caused by rough polishing, so as to minimize polishing damage.
