During the use of the polishing machine, it may be affected by some factors, resulting in equipment failure, which affects its normal operation. Then you know why the polishing machine malfunctions? What are the main reasons? How to avoid it? The following China Polishing Machine manufacturers will come to understand:
The first is to use the polishing machine to pay attention to the operation of the polishing machine is not a specification, can not blindly operate the polishing machine, which is very easy to cause damage to the polishing machine; when using the polishing machine to avoid the polishing machine overload work Because this will directly affect the life of the polishing machine and work efficiency; in addition, when using the polishing machine, if the polishing machine malfunctions, it should be time to stop the inspection, and should not continue to use the polishing machine.
Polishing is divided into two stages. The first is coarse polishing. The goal is to remove the polished damage layer. This stage should have a large polishing rate. The surface damage caused by rough polishing is a secondary consideration. Small; followed by fine polishing, the goal is to remove the surface damage caused by rough throwing, so that the polishing damage is reduced to a small.
When the polishing machine is polished, the polished surface of the sample and the polishing disc should be pressed against the polishing disc in parallel and evenly symmetrically, to prevent the sample from flying out and the new wear scar due to too much pressure. At the same time, the sample should be rotated and moved back and forth along the radius of the turntable to prevent the polishing material from being worn too quickly. In the polishing process, it is necessary to add a polishing liquid or other polishing aids to connect the polishing materials to a certain humidity.
Too much humidity will weaken the wear scar, so that the hard phase of the sample will appear embossing and the non-metallic mixture in the steel and the graphite phase in the cast iron will produce a "tailing" sign; if the humidity is too small, the sample will be generated due to frictional heat generation. The temperature rises, the lubrication is reduced, the polished surface loses its light, and even dark spots appear.
