How to improve the life of polishing machine equipment?
Polishing machine in the operation of the correct or not with its application life is closely involved, often see the same product in different manufacturers plant applications, see the wear and polishing machine is also a great difference. Incorrect application of machines and skilled workers, the installation of the machine when the machine is not accurate and power supply and a series of problems, and even without the approval of the manufacturers of the polishing machine and other parts of the modification, not in accordance with the manufacturers to provide safe operation of the application of the code and so on have a great relationship.
Polishing machine is the most common, the most important step in metallographic sample, polishing machine polishing, sample grinding surface and polishing disc should be absolutely parallel and evenly light pressure on the polishing disc, pay attention to avoid the specimen fly out and the pressure is too large to produce new grinding marks. Should also make sample rotation and along the radius direction of the turntable move back and forth, to avoid polishing fabric local wear too fast in the polishing process to increase the powder suspension, so that the polishing fabric moisture to keep certainly. Humidity is too general to weaken polishing grinding marks and the specimen in hard phase showed embossed and steel in non metallic inclusions in steel and cast iron graphite phase "trailing" phenomenon; humidity is too small, due to friction heat will make the sample temperature, reduced lubrication, grinding to lose luster, and even spots, light alloy will throw the wound surface.
