Factory For Walnut Shell Abrasive - Pink Funsed Alumina PA – Junda Detail:

Production process:

The smelting process of chrome corundum is the same as that of white corundum, except that a certain amount of chrome oxide is added in the smelting process, which is light purple or rose color. Chromium corundum due to the introduction of Cr3, + improved the toughness of abrasive, its toughness is high white corundum, and close to white corundum hardness, used for processing large ductile material, its processing efficiency is higher than white corundum, and workpiece surface roughness is better also, chromium corundum adapted to the high toughness hardened steel, alloy steel, high precision measuring tool and instrument parts finish requirement artifacts.

Product Introduction:

1, chrome corundum is aluminum oxide powder as the main raw material, adapted to chromium oxide, by high temperature arc furnace smelting.

2, the color is pink, hardness is similar to white corundum, toughness is higher than white corundum. The abrasives manufactured by it have good durability and high grinding finish.

3, suitable for measuring tools, machine tool spindle, instrument parts, thread workpiece grinding and other precision grinding.
