flap disk.jpgOrdinary abrasive bonded abrasives are flap disk in which a fixed abrasive is consolidated into a certain shape by a bonding agent and has a certain strength. Generally composed of abrasives, binders and pores, these three parts are often referred to as the three elements of bonded abrasives.

  The abrasive plays a cutting role in the flap disk. Bonding agents are materials that consolidate loose abrasives into flap disk, both inorganic and organic. Inorganic binders include ceramics, rhododendron and sodium silicate; organic resins, rubber and shellac. The most commonly used are ceramic, resin and rubber binders. The air hole acts as a chip and chip on the wear debris during grinding, and can accommodate the coolant to help dissipate the heat. In order to meet certain special processing requirements, some fillers such as sulfur and paraffin may be impregnated in the pores to improve the performance of the flap disk. This filler, also known as the fourth element of the flap disk.
