Classification of bonded abrasives

Consolidated abrasives can be divided into ordinary abrasive bonded abrasives and superhard abrasive bonded abrasives according to the abrasive used. The former uses ordinary abrasives such as corundum and silicon carbide, and the latter is made of superabrasives such as diamond and cubic boron nitride. In addition, there are some special varieties, such as sintered corundum abrasives.
Ordinary abrasive bonded 115 golden star cutting disc are abrasive tools 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 abrasive tool. Bonding agents are materials that consolidate loose abrasives into abrasives, 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 abrasive tool. This filler, also known as the fourth element of the abrasive tool.
Items that represent the characteristics of conventional abrasive bonded abrasives are: shape, size abrasive, particle size, hardness, texture, back pile, backing, and bonding agent. Abrasive hardness refers to the difficulty of the abrasive particles falling off the surface of the abrasive tool under the action of external force. It reflects the strength of the abrasive particles held by the bonding agent.
