Flap disc (flap wheel) known as elastic grinding disc, is made of plastic or fiberglass backing plate, adhesive and abrasive cloth sheet, suitable for angle grinder. Generally there are 36 flaps, 56 flaps, 72 flaps, 80 flaps and several kinds of granularity between 40# and 320#. Material has brown alumina, zirconium alumina, silicon carbide, etc. Can be used in shipbuilding, automotive, aviation, machinery, instrumentation, bridge and construction industry and furniture of all kinds of metal and non-metallic materials surface rust, paint, burr, grinding welding seams.

Grinding head is the general name of a small grinding tool with handle, which is used in electric mill, hanging mill and hand drill.The main types are: ceramic grinding head, rubber grinding head, diamond grinding head, abrasive cloth grinding first class

1) ceramic grinding head: granular sand (generally brown corundum, white corundum, chrome corundum, silicon carbide) is sintered by ceramic binder, with metal handle in the center.Mainly grinds each kind of metal, USES the aperture inner wall grinds, the mold correction.

2) rubber grinding head: the fine-grained sand is combined and synthesized by the rubber binder, which is used for the polishing of the mold.

3) abrasive cloth grinding head: several long square abrasive cloth pieces are glued around the metal handle.The particle size is generally in 60#-320#, used for the polishing of the inner wall of the aperture.

4) best impeller diamond grinding head: a kind of stone material, ceramic materials and other non-metallic materials of grinding tools, especially involving a with diamond alloy grinding tools for grinding body, it includes substrate and a mill body, in which several mill body clearance to fixed to the substrate, the mill body is also on the surface of the grinding head grinding gap setting, among them, the substrate is the best by a certain toughness of adhesive materials, grinding body made of diamond alloy materials, best the utility model is characterized by a high grinding performance, manufacture simple, low cost and high quality of grinding and can apply to the characteristics of large grinding. The polishing wheel is a compacting planar wheel, which is made of several polishing wheel plates compacted, and the outer surface of each polishing wheel plate is uniformly coated with a layer of polishing oil. There is no need to add oil separately during the polishing process.

It is simple in structure and easy to use. Good polishing effect. The hardness of the polishing wheel is determined by the distance of the stitching line. The smaller the distance of the stitching line, the higher the hardness of the polishing wheel. In order to make the polishing wheel more soft, the polishing wheel should be made with sufficient distance between the stitching and the edge of the wheel (also without stitching). Polishing large workpiece, also useful with a special air - cooling device polishing wheel.
