Abrasive used by the abrasive can be divided into ordinary abrasive abrasive and superabrasive abrasive . The former corundum and silicon carbide abrasive general , the latter made of diamond and cubic boron nitride and other superhard abrasive. In addition , there are some special varieties , such as sintered corundum abrasives etc. .
Ordinary abrasive abrasive is bonded abrasive solid ordinary form a certain shape and a certain intensity of abrasive. Generally abrasive , binder and pore structure, which is often called the abrasive three parts of the three elements .
In abrasive abrasive cutting action from the . Binding agent is a solid form of the abrasive loose abrasive materials , inorganic and organic types. Ceramic inorganic binders , such as magnesite and sodium silicate ; organic resin , rubber and shellac . The most commonly used is a ceramic , resin and rubber binders .
Holes in the ground of debris from the chip and chip effect, and can accommodate coolant helps grinding heat dissipation . In order to meet some special processing requirements, the pores can also dipped some fillers , such as sulfur and paraffin , etc., to improve the performance of the abrasive . This filler is also called the fourth abrasive elements .
Said ordinary abrasive abrasive characteristics of the project are: the shape, size abrasive , grain size, hardness , organization and binding agents . Grit abrasive hardness refers to the external force , from the degree of difficulty shedding the abrasive surface , which reflects the bond abrasive grip strength .
