① grinding time is short, the processing efficiency is high: the arc of contact of the grinding wheel and the workpiece due to the strong grinding a removal of a large quantity, than the conventional grinding contact arc, high metal removal rate by forming FORGING the greensheet directly grinding, thereby reducing the grinding cycle. In the same time, the grinding depth, reduction in the number of workpiece reciprocating, saving workbench change to empty grinding time, the processing efficiency is 3-5 times higher than ordinary grinding fuller play to the potential of machine tools and grinding wheels, making powerful grinding and improve work efficiency.
② grindstone easily broken wear, tool wear is small: the table feed speed is low, the thickness of the grinding thin, single active abrasive grains of the cutting wheel to withstand the grinding force is small, although the wheel contour cusp part of the force than and combine weak, but the grinding force is still insufficient to make a single grain crushing wear, but can only produce abrasion wear, it is possible to maintain the shape of the grinding wheel in a more permanent, and thus guarantee high shape accuracy of the workpiece. When using a CBN wheel, the accuracy of the shape of the workpiece can be further improved.
③ stable workpiece precision machining high precision: the abrasive grinding wheel is slowly and gradually cut into the workpiece material, can greatly improve the grinding conditions to reduce grinding vibration. Processing wheel and workpiece contact arc, enables the grinding vibration damping to reduce flutter, the workpiece surface waviness and surface stress reducing, not easy to produce grinding cracks. Therefore, the accuracy of the workpiece is relatively stable, high precision machining type surface grinding accuracy up to 2-51. zm, the roughness generally up Ra0.631. zm, some up to a0.161. zm.
4) grinding force and grinding heat:
⑤ creep feed grinding machining hardened materials, wear-resistant alloys and ceramic materials difficult to machine materials with unique advantages, and the process does not produce glitches.
Binder refers to the Bonded Abrasives various types of binder and abrasive bonded materials. Bonded Abrasives usually ceramic, resin, rubber, magnesite four categories binder. These four types of binder to the largest proportion of vitrified bond. Clay, feldspar, loess, velcro disc,quartz stone composed of different abrasives for different purposes and different system of law (pouring or suppress) vitrified ceramic binder material. The resin binder is a phenolic type of resin, two broad categories of powder resins and liquid resin, is based on a different manufacturing method and by different purposes for various resin binder. The rubber binder artificial SBR Buna rubber and liquid rubber three categories, according to the different system of law and the use of different and divided into various rubber binder. Magnesite binder material consisting of magnesium oxide and magnesium chloride material, mainly used for fine-grained abrasive for fine processing purposes. The the various binders of Code as follows: the binder name combined with the agent codenamed ceramic binders V resin binder rubber binder B R magnesite binders MG.Bonded abrasives
