How is Magnesium Oxide MgO used for polishing

[Abstract]:
From a microscopic point of view, Magnesium Oxide MgO has a sharp shape, so it has a good grinding effect and is suitable for polishing and fine polishing.

Polishing is the modification of the surface of a workpiece using polishing tools and abrasive particles or other polishing media. In some ball products, such as carbon steel balls, needle bearings, glass balls, etc., the surface of the object will be polished to be as shiny as we see on the market. Magnesium Oxide MgO is a white powder with fine particle size, it is a fine polishing auxiliary material. From a microscopic point of view, Magnesium Oxide MgO has a sharp shape, so it has a good grinding effect and is suitable for polishing and fine polishing.

Magnesium Oxide MgO

In the polishing process, a raw material called lightweight Magnesium Oxide MgO is used, and the surface of the steel ball is modified by using flexible polishing tools and Magnesium Oxide MgO abrasive particles. When producing bearing steel balls in large quantities, the method of drum polishing is often used. During polishing, the high-speed rotating polishing wheel (circumferential speed above 20 m/s) presses against the workpiece, causing the abrasive to roll and micro-cut the surface of the workpiece, so as to obtain a bright processed surface, and the surface roughness can generally reach Ra0.63 ~0.01 micron Mattes glossy surfaces to improve appearance when non-greasy matting polishes are used.

In the selection of Magnesium Oxide MgO, the Magnesium Oxide MgO produced by the dolomite carbonization method and the heavy magnesium carbonization method are easy to use, and the brine method is generally not used, because the brine method produces needles and rods, so it is not easy to use. Experience has proved that slightly higher calcium content is better to use, and the content of Magnesium Oxide MgO will also affect the polishing time. Generally, the content of 93% or more is used.
