Vitrified Bond Grinding Wheels for PCD and PCBN

vitrified diamond grinding wheels for pcd & pcbn tools
vitrified diamond grinding wheels most widely used for pcd, cvd, pcbn, carbide, vitrified cutting tools and other cutting tools such as milling cutter, drill bit, reamer, etc. 
Vitrified bonded grinding wheel has high temperature resistance.High processing efficiency, good rigidity, in the grinding process to maintain the shape of cutting tools, finished product size accuracy can be guaranteed and other advantages.
Using Vitrified bonded diamond grinding wheel to grind PCD tools can improve the grinding efficiency to the greatest extent.
And grinding ratio is small, wear-resisting degree is high, service life is long, processing cost is low, have extensive practical significance and promotion value.
The grinding surface quality of Vitrified bonded diamond grinding wheel is good, which is close to the grinding quality of metal bonded grinding wheel, and its grinding efficiency is very high, about 4 times of that of metal bonded grinding wheel, which has been proved by experiments.
However, due to the poor thermal stability and large inertia of diamond, it is difficult to prepare the Vitrified bonded diamond grinding wheel, and the performance of the grinding wheel batch is not stable. Therefore, the extensive application of the Vitrified bonded diamond grinding wheel is limited.

generally speaking, the more the combined dose, the stronger the control on the abrasive, the harder the abrasive particles fall off, and the higher the hardness of the grinding wheel. 
during grinding, the blade of the grinding wheel is not good and it is easy for the grinding wheel to remain still. the life of the diamond grinding wheel will be increased. however, the surface of the composite disc is easy to crack.   (2) the effect on the binding strength of the binder content and diamond abrasive.    the hardness of the composite sheet is very high. during the external grinding process, the diamond on the surface of grinding wheel receives great grinding force and impact force. 
if the vitrified bond dose is too small, the vitrified bond does not keep enough on the diamond, which results in that some diamonds do not play a full grinding role and begin to fall off, resulting in shorter life of the vitrified diamond grinding wheel. 
however, when there are too many binders, the hardness of the grinding wheel is too high, and the cutting edge is not enough, it is easy to cause the composite sheet to collapse, resulting in the increase of reject rate.   (3) influence on the structure of grinding wheel.    as the size of the binding agent used is finer than that of diamond, and the binding agent will be densified in the process of burning. 
with the increase in the content of binders in the vitrified diamond grinding wheel, the more compact the structure of the grinding wheel, the more clogging the grinding wheel is likely to occur and the grinding wheel will not move. it is often necessary to use the ordinary grinding wheel to cut the super-hard material grinding wheel, remove the redundant binders, make the new diamond cutting edge participate in the next grinding, and reduce the working efficiency of the grinding wheel.
