How does the life of the polishing machine increase?
May 26, 2017

Polishing machine in the operation of the correct or not with its application period has a close involvement, often see the same product in different manufacturers plant applications, see the polishing machine wear is also very different. Improper application of the machine and the application of unskilled workers, the machine is not accurate in the installation and power supply and a series of problems, and even without the advice of manufacturers without any modification of the polishing machine and other parts, not in accordance with the manufacturers The safety of the implementation of the Code of Practice and so on the issue has a great relevance.

Polishing machine is the most common and most important step in the current metallographic sample. When the polishing machine is polished, the sample grinding surface and the polishing disc should be absolutely parallel and evenly pressed gently on the polishing disc, And because of the pressure is too large to produce new wear marks. At the same time, the specimen should be rotated and moved back and forth along the radius of the turntable in order to avoid local wear of the polished fabric. To keep the powder suspension in the polishing process, keep the polished fabric constant. The humidity is too large will weaken the grinding of the grinding effect, so that the hard phase of the sample showing the relief and non-metallic inclusions in steel and cast iron in the graphite phase to produce "trailing tail" phenomenon; humidity is too small, due to friction heat will make the sample Heating, reducing the role of lubrication, grinding luster, or even dark spots, light alloy will be wound appearance.
