Vitrified bond CBN grinding wheel has high grinding efficiency, very good condition stability, high durability, finishability and also other advantages, therefore it has become the fastest growing variety among different kinds of bond CBN grinding wheels. From 1980 to 1993, inside bond component ratio of CBN grinding wheel like diamond flap wheel at https://www.superabrasivetools.com/diamond-flap-wheel-disc/ , vitrified bond increased from 4% to 37%, having a sharp rise inside the trend.

For grinding materials which are difficult to be processed with higher strength, high hardness, high toughness, high viscosity, temperature resistance and corrosion resistance, the grinding tools really should have good physical and chemical properties and mechanical properties. In order to improve grinding efficiency and precision, the grinding wheels needs to have high toughness and long service like. New kind of vitrified bond CBN grinding wheel could perfectly meet these grinding performance requirements. The wide using the new CBN grinding wheel is incompatible using the physical and chemical properties from the excellent vitrified bond. The performance with the bond interacts together with the performance on the CBN abrasive to accomplish a similar high crystal strength to create a phase transition. Tough and brittle microcrystalline pores let the bond to shield the normal toughness of CBN abrasive grains.

With conventional abrasives, infeed will be .001"–.002" per pass whereas with cBN wheels it could well be a fraction in this amount. During the initial dressing period, operators dress a newly installed wheel aggressively, often dressing .020"–.030" in the wheel face. A cBN wheel requires only a small fraction of this infeed. The usable abrasive depth of your cBN wheel is often .250"–.375", so wheel manufacturers want to make certain the wheel face and thread form are near to operating tolerances.

Care should be taken when dressing a cBN wheel. Aligning the dresser together with the face from the wheel is vital to prevent wheel chipping, and also to reduce the total dress amount needed for the machine to provide good quality parts.

Continuous gear generation machines utilize a threaded wheel to create the involute form over a gear tooth. As continuous generation machines have evolved, efficient dressing features have improved. Faster grinding methods seemed to be developed by introducing multiple starts or multiple wheel threads on the face with the wheel. By introducing diamond rolls with multiple ribs to suit the cBN wheels, dressing times have already been significantly reduced.

Aside from producing better-quality cutting edges, the utilization of CBN grinding wheels for just a variety of hardened cutting tools can help to eliminate your overall price of grinding by 20-50%, according to its applications. Since there is little conditioning involved, treadmills require even less downtime for just about any wheel maintenance.

When selecting your CBN wheel for tool and cutting operations, bond type, grit size, and concentration are definitely the factors it is best to take into consideration when replacing any aluminum oxide wheel.
