Actual production, especially large-scale hand-finishing quality often unstable, mainly because the operator level, the state can not afford varied, but test is uniquely determined. In addition, some coated abrasive products with the "sand", grit size range is large, will increase the grinding instability. Scouring can balance manually instability and uncertainty of surface quality, maximizing the reliability of hand-trimming.

    No suitable manual polishing Bonded abrasives products: distribution of dense sand sandpaper, once blocked, polishing effect is not satisfactory it. For demanding applications, such as metal decorative pieces, and after the Road paint thinner, softer material of the workpiece is easy to produce dust, sanding debris, if not completely clean, the surface will certainly cause additional damage. And traditional live sand on woven abrasivediscs class products, scouring pads especially suitable for aluminum, copper alloys, such as hardness less prone to dust or polishing materials, such as water pipe pieces (tees, valves, elbows, etc.), , patience dust stronger. Hand-polished with a little shallow hairline will. Before polishing than not, will generally improve gloss of 20 to 30%. Program Comments: Quick improve the finish to rust easily blocked, and scattered rust powder is easy: all kinds of carbon trim parts, long term storage refurbished parts or equipment, printed circuit board corrosion removal, as well as a large number of routine maintenance of tools and machinery are need to rust.

  Abrasive Category
Wherein the abrasive products are mainly divided abrasive corundum and silicon carbide abrasive two categories, specifically, there are basically the following:
1, corundum abrasive, the main component of Al2O3, with medium hardness, toughness, particle Fengrui, relatively inexpensive, suitable for machining high tensile strength of the metal. Microcrystalline corundum abrasives and black corundum aabrasivesare its derived varieties.
2, white fused alumina abrasive, slightly higher than the hardness of corundum, but poor toughness, easy to cut into the workpiece during grinding, good self-sharpening, less heat, grinding ability, high efficiency. Chromium corundum abrasive is its derived varieties.
3, single crystal corundum abrasive material particles are composed of a single crystal, and has a good polygonal cutting edge, high hardness and toughness, grinding ability, less grinding heat, the disadvantage is the high cost of production, yield lower, so the price is relatively high. Corundum abrasives are also crystalline compound, slightly lower hardness, crystal size is fine, good wear resistance.
4, black silicon carbide abrasive, green silicon carbide abrasive, abrasive cubic silicon carbide, silicon carbide abrasive cerium, etc., are silicon carbide abrasive, the main ingredient is silicon carbide SiC, high hardness, brittleness, sharp abrasive grains, good thermal conductivity, strong wear resistance, more suitable for processing hard and brittle metallic and non-metallic products.
