How to improve the life of the polishing machine?

The correctness of the polishing machine during operation is closely related to its application life. It is often seen that the same product is used in different factory buildings, and the wear of the polishing machine is also very different. Inappropriate application of machines and unskilled workers, inaccurate installation of the machine when entering the market, and a series of problems such as power supply, even without the manufacturer's advice to modify the polishing machine and other components, not according to the manufacturer The application of the safety code of practice and so on are all very relevant.

The polishing machine is the most common and most important step in the current metallographic sample. When the polishing machine is polished, the sample surface and the polishing plate should be absolutely parallel and evenly pressed on the polishing plate, taking care to avoid the sample flying out. And new wear marks 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 avoid local wear of the polishing fabric too fast. During the polishing process, the fine powder suspension should be continuously increased to maintain the humidity of the polished fabric. Too much humidity will weaken the wear scar, so that the hard phase of the sample will appear embossed and the non-metallic inclusions in the steel and the graphite phase in the cast iron will produce a "tailing" phenomenon; if the humidity is too small, the sample will be generated due to frictional heat generation. Heating, reducing lubrication, tarnishing of the surface, and even dark spots, light alloys will throw the appearance.
