The automatic polishing machine is composed of base, polishing head, table, protective cover/cover, hydraulic system, electronic control system, auxiliary fixture and other basic component bases, which are developed on the basis of ordinary polishing machine improvement and innovation, and are suitable for factory use with relatively large output.
The motor is the power source of the polishing head, and the polishing accessories constitute the entire polishing head, the polishing accessories are fastened on the polishing head, after the motor power starts, by adjusting the position of the polishing head, the polishing accessories are in full contact with the object to be polished, the polishing liquid / polishing wax added during the polishing process can get a better finish, and can be fixed on the workbench to install a sink, water circulation system, etc., to achieve the effect of wet throwing, the protective cover can prevent the object from falling off during the polishing process and flying out to hit the personnel, and at the same time after installing the dust collector, It can effectively eliminate indoor dust.
The key to polishing machine throwing operation is to try to get a large polishing rate, in order to remove the damage layer produced by polishing as soon as possible, but also to make the polishing damage layer will not affect the final observed tissue, that is, will not cause false tissue, the former requires the use of coarser abrasives to ensure a larger polishing rate to remove the polished damage layer, but the polishing damage layer is also deeper, the latter requires the use of fine materials, so that the polishing damage layer is shallow, but the polishing rate is low, a good way to solve this contradiction is to divide the polishing into two stages, The purpose of rough polishing is to remove the polishing damage layer, this stage should have a large polishing rate, the surface damage formed by rough polishing is a secondary consideration, but it 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 that the polishing damage is minimized.
The cause of high fever in automatic polishing machines.
Overload operation This situation is generally not felt at the beginning of use, after a period of use of the temperature rises sharply, this situation is generally a lack of power supply voltage or equipment overload, such as a small round tube polishing machine, polishing a relatively long steel pipe, and the bracket does not have a guide wheel, so that when polishing, the steel pipe transportation resistance will be very large, add the motor running load, the use of a short time will feel that the motor is very tricky.
Poor heat dissipation of the motor This situation is generally presented in small processing plants, because the production task is serious, rarely clean and maintain the equipment, resulting in the motor heat dissipation hole to cover a lot of dust, its heat dissipation is greatly reduced, will present the motor overheating phenomenon, so often more motors for cleaning and maintenance.
