Dear customer: Hello!
In order to better understand and use the company’s consumables (sand belt, cloth wheel, impeller, nylon wheel, hemp wheel, steel wire wheel, etc.), please carefully read the following points before use:
1. Scope of Application:
Suitable for all kinds of stainless steel, metal, wood, furniture, stone and other fields of surface large area rough polishing, grinding, rust removal and grinding; It has the advantages of high polishing efficiency, long service life and so on, and is widely used in automobile manufacturing, heavy machinery, ship repair, stainless steel, aluminum alloy, hardware and decoration and other industries.
2. the choice of consumables:
1, nylon wheel is an important branch of abrasive tools products, is following the abrasive belt, grinding wheel and other strong cutting grinding products after the grinding products. Nylon wheel products are mainly composed of nylon fiber net, grinding medium (mineral sand), bonding resin and other main components, which may add heat absorption additives, fillers, colors and other additives. What we mainly do is the laminated wheel is made of industrial white cloth (Nylon Prebond) through the roller coating method (glue containing binder and abrasive, etc.) coated and stacked one piece of pressure combined in the oven baking curing, and finally cut;
2, sand belt is composed of substrate (cloth, paper, film), mineral sand, composition, generally grinding stainless steel, usually choose zirconium corundum material, ceramic material. The abrasive of alumina accumulation, when grinding the head and tank, is generally used for 80#, 120#, 180#, 240#, 320#, 400#, 600#. At this time, the hardness of the rubber contact wheel is generally 55° to 65°. If the mirror is required, 800#, 1000#, 1200# should be used behind, then the rubber contact wheel should be softer, and the hardness is about 45°. Before loading the sand belt, be sure to ensure that the direction of the machine is consistent with the direction of the arrow on the sand belt, and let the sand belt idle for one minute before contacting the workpiece. The sand belt should generally be placed in a dry and ventilated environment, the general temperature is best at 18 to 22 ° C, and the humidity is 40% to 65%.
RA 0.1 600# RA 0.2 400#
RA 0.4 320# RA 0.8 240#
3, the higher the abrasive belt line speed, the higher the grinding efficiency, coarse abrasive belt line speed is generally 12-20m/s, fine grinding is 25-30m/s; When the oxide layer is thick, the cost performance of ceramic materials is generally good, with 36#, 40#, 60#, 80#;
4, 2B plate polishing mirror, can directly use the cloth wheel polishing wax;
5, ordinary cold plate polishing, you can start from 240#, 400#, 600#, cloth wheel with wax, you can go to the mirror, but there is silk, if there is no silk mirror, sand belt to use 1200# or even 4000#;
6, the hot plate generally starts from 80# grinding, if you need wire drawing effect, you can sand belt grinding to 400# or 600#, with blue nylon wire drawing, or need thicker lines, with red.
