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

Chrome oxide is dichromium trioxide, commonly referred to as 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, after cooled down it still turns to green. The crystal is incredibly hard and most stable, even within the glowing state the hydrogen is passed through, it nevertheless has no alter. It’s soluble in heated Potassium bromate solution, slightly soluble in acids and alkalis, virtually insoluble in water, ethanol and acetone. Its relative density is five.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 are able to frequently see the fused chrome oxide. It might also be utilized for the colorants of enamel, ceramics, artificial leather, construction materials, or catalysts for organic chemical synthesis, sun proof paint, abrasive components, green polishing paste and special ink for printing paper income. In addition to, it can be utilized within the production of refractory such as high chrome brick, chrome corundum brick. Then you definitely might wonder why we use Chromium Oxide as abrasive material?

The purpose is since the lapping tool and perform piece are soft, so inside the polishing approach the abrasive material is suspended among the perform piece and lapping tool, mainly use the chemical action of plane polishing machine along with the function piece surface to create a layer of really soft oxide film, and the membrane at convex point can easily be rub out by abrasive material, in this method we are able to get extremely fine surface roughness, processing a number of steel, hardened steel, cast iron, copper and aluminum and their alloys, tough alloy, ceramic, glass and some plastic products etc. the surface polishing of a operate piece is typically carried out following becoming polished; for manual surface polishing, the polishing agent has to be coated on a polished plate, you must hold the operate piece for a straight line reciprocating movement or "figure 8” motion, possessing polished for a particular time frame, the work piece need to be turned from 90 degrees to 180 degree to prevent the inclination of a function piece.

The function piece of a surface polishing machine contacts using a grinding gear randomly, the higher spot might be trimmed each other, the error is decreased progressively, as well as the precision is also improved, so it may be used to detect the work piece, making targeted modifications towards the polishing position and grasping the grinding time, making sure the precision in the dimension and shape, getting trustworthy processing top quality; for the surfaces around the function 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 large batch of simple parts can also be polished on the surface polishing machine, so it could widely utilized for processing different high precision surface in the single and modest batch production, and may be used for mass production, could be carried out the cutting length between 0.01|¨¬m and 0.1|¨¬m of a work piece, getting extremely higher accuracy plus a really low Ra worth, but we usually can't raise the position accuracy in between the processing surface as well as the other surface.
