The impeller is called an elastic grinding disc, which is made of plastic or fiber mesh covered with abrasive cloth sheets, which are suitable for angle grinders. Generally, there are 36 pages, 56 pages, 72 pages, and 80 pages, and the granularity is generally between 40#-320#.
The materials are brown corundum, zirconium corundum, silicon carbide, etc. It can be used in shipbuilding, automobile, aviation, machinery, instrumentation, bridge and construction industry furniture metal and non-metallic materials to remove rust, paint, burr, and weld seams.
Grinding head is a general term for small shank grinding tools, which are used in electric grinders, hanging grinders, and hand drills. There are many types, mainly: ceramic grinding heads, rubber grinding heads, diamond grinding heads, abrasive cloth grinding heads, etc.
1) Ceramic grinding head: Granular sand (usually brown corundum, white corundum, chrome corundum, silicon carbide) is sintered by a ceramic bond, and the center is supplemented by a metal handle. It mainly grinds various metals for grinding the inner wall of the aperture and mold correction.
2) Rubber grinding head: The fine-grained sand is synthesized by the combination of rubber binders for mold polishing.
3) Emery cloth grinding head: multiple pieces of rectangular abrasive cloth, glue around the metal handle. The particle size is generally 60#-320#, which is used for polishing the inner wall of the aperture.
4) Diamond grinding head for louver wheel: a grinding tool for non-metallic materials such as stone and porcelain materials, especially a grinding tool with diamond alloy as the grinding body.
It includes a base body and several grinding bodies. The several grinding bodies fix the base body with gaps. The grinding bodies are also arranged in gaps on the grinding surface of the grinding head. The base body is preferably made of a certain toughness bonding material, and the grinding body is preferably made of diamond. The utility model is made of alloy material, and the utility model has the characteristics of high grinding performance, simple manufacture, low cost, high grinding quality and is suitable for large-scale grinding.
The polishing wheel is a press-fitted flat wheel, which is formed by pressing a plurality of polishing wheel pieces, and the outer surface of each polishing wheel piece is uniformly coated with a layer of polishing oil layer. The polishing process does not require a separate oil.
The utility model has the advantages of simple structure, convenient use and good polishing effect. The hardness of the polishing wheel is determined by the distance of the suture line. The smaller the distance of the suture line, the higher the hardness of the polishing wheel. In order to make the polishing wheel softer, the polishing wheel production should pay attention to keeping a sufficient distance between the suture and the edge of the wheel (there are also no sutures). For polishing large workpieces, it is also useful to have a polishing wheel with a special air-cooling device.
