Brief introduction
With a good proportion of the vitrified bonded abrasive, the compacts, drying, roasting and dressing made with a lot of holes, with the cutting of abrasive grit.
Abrasive grains exposed on the surface portion of its corners as cutting edges. Divided into: ceramic grinding wheel (carbonization
Silicon, corundum, corundum, etc.) and ceramic superhard grinding wheel (vitrified diamond grinding wheel and vitrified CBN grinding wheel) two categories.
Property
The characteristic features of the grinding wheel abrasive particle size, binder, hardness, structure, and other factors determined shape and size. In superhard
grinding wheel hardness and organizations are generally neglects to mention.
Advantage
1, the grinding efficiency;
2, with a high wear resistance (abrasion resistance wheel, abrasive consumption, particularly in the grinding very hard brittle workpiece most obvious);
3, small grinding force, low grinding temperature;
4, high precision grinding of the workpiece surface quality of the workpiece to maintain good shape.
Therefore, vitrified diamond grinding wheel in diamonds, industrial ceramics, PDC, polycrystalline diamond, synthetic diamond tools, CBN, carbide high-brittle materials and some
special materials grinding, with more and more obvious advantages in gold
The development of diamond abrasive has a good prospect. Is considered to be high-speed, high efficiency, high precision, low grinding cost, low environmental
pollution, high-performance abrasive, with more and more widely used, is the recent world competing tools for grinding hot research and development.
Freedom for small workpieces in grinding wheels , with this wheel for processing, is a better choice, such as punch machine wheel. Because these are small grinding machining accuracy requirements are not very high, but not often wheel dressing, and corundum grinding wheel and a good self-sharpening cutting just apply.
