As a grinding tool there are many grinding materials, such as sanding belt, sandpaper, grinding wheel, impeller, grinding fluid, grinding paste, today let us understand the flap disc .as a new type, flap disc high elastic coated abrasive shaped products, flap disc has good elasticity, grinding does not burn the workpiece and other characteristics, mostly used in angular polishing machine or electric machine. Impeller is widely used in ships, Bridges, automobiles, aircraft, stainless steel products weld grinding and large areas of oil removal, rust removal and die, plating dressing and polishing. In order to make the grinding fluid play a full role in the grinding process, the supply mode of grinding fluid can not be ignored.
The pouring method supplies the grinding fluid, and the grinding material grinding fluid is often not easy to enter the grinding zone during grinding, the main reasons are as follows:
First, the surface pores of the grinding wheel are air, due to the role of centrifugal force, from the center to the circumference of the grinding wheel, the larger the pores of the grinding wheel, the higher the speed, the greater the impact.
Second, the influence of the grinding wheel cover, compared with the cover, the dynamic pressure of the air flow increases by about 50% on average.
Third, when the grinding wheel rotates, its surrounding also produces rotary air flow, the higher the speed of the grinding wheel, the greater the impact of the air flow.
The flap disc is made of plastic or fiber mesh cover adhesive and emery cloth sheet, suitable for angular grinder. Generally there are 36 pages, 56 pages, 72 pages, 80 pages several kinds.
The particle size is generally between 40#-320#.
Materials are brown corundum, zirconium corundum, silicon carbide and so on.
Abrasive flap disc can be used in shipbuilding, automobile, aviation, machinery, instrumentation, bridge and construction industry and furniture of metal and non-metallic materials of various profiles of rust removal, paint removal, burr removal, grinding weld.
