Do You understand why We Use Chromium Oxide as Abrasive Material?

Chrome oxide is dichromium trioxide, commonly called Green Chrome Oxide. It’s tiny hexagonal crystal with a color from light green to dark green. It can be added into Ceramic Pigment or Chrome Green Ceramic Pigment. It turns brown when acquiring heated up, following cooled down it nonetheless turns to green. The crystal is extremely challenging and most stable, even inside the glowing state the hydrogen is passed via, it nonetheless has no alter. It’s soluble in heated Potassium bromate resolution, slightly soluble in acids and alkalis, practically insoluble in water, ethanol and acetone. Its relative density is 5.22, melting point about 2435℃ and boiling point 4000℃. It really is irritating. It’s primarily used for smelting metal chromium and chromium carbide, so we can often see the fused chrome oxide. It may also be utilized for the colorants of enamel, ceramics, artificial leather, building components, or catalysts for organic chemical synthesis, sun proof paint, abrasive supplies, green polishing paste and unique ink for printing paper funds. In addition to, it may be used inside the production of refractory for example high chrome brick, chrome corundum brick. Then you may wonder why we use Chromium Oxide as abrasive material?

The reason is since the lapping tool and perform piece are soft, so in the polishing method the abrasive material is suspended among the work piece and lapping tool, mainly make use of the chemical action of plane polishing machine and the perform piece surface to create a layer of very soft oxide film, as well as the membrane at convex point can easily be rub out by abrasive material, in this method we can get really fine surface roughness, processing a variety of steel, hardened steel, cast iron, copper and aluminum and their alloys, difficult alloy, ceramic, glass and some plastic items etc. the surface polishing of a perform piece is normally carried out right after getting polished; for manual surface polishing, the polishing agent should be coated on a polished plate, you must hold the perform piece for a straight line reciprocating movement or "figure 8” motion, possessing polished for any certain time period, the function piece must be turned from 90 degrees to 180 degree to prevent the inclination of a perform piece.

The work piece of a surface polishing machine contacts having a grinding equipment randomly, the higher spot may be trimmed each other, the error is reduced steadily, along with the precision can also be improved, so it may be utilized to detect the perform piece, creating targeted adjustments towards the polishing position and grasping the grinding time, ensuring the precision of the dimension and shape, getting reputable processing top quality; for the surfaces around the perform piece that are to be grinded partly such as facet, square hole and narrow slit, and so forth., we can also hand-hold the grinding gear to polish them, the surface on a big batch of basic parts also can be polished around the surface polishing machine, so it could broadly utilized for processing various higher precision surface within the single and modest batch production, and may be utilized for mass production, may be carried out the cutting length amongst 0.01|¨¬m and 0.1|¨¬m of a operate piece, getting really higher accuracy plus a really low Ra value, but we normally cannot raise the position accuracy amongst the processing surface along with the other surface.
