Vitrified Bond CBN Grinding Wheel

Vitrified CBN Grinding Wheel is your first choice to achieve the effect of high-speed, high-efficiency and high-precision. and they have been widely used in the processing of hydraulic tappets, Camshafts, Crankshafts, glibs, machine tool parts, and cutting tools. The manufacturing technique developed can be used to make grinding tools of all spections with a speed up to 120m/s.

The Grain Size Selection

The grain size is usually decided according to the requirements of the work-piece's surface roughness and processing efficiency. Furthermore, the affect of bond force and grinding mode (e.g. surface grinding, end grinding, cylindrical grinding, internal grinding etc.) should also be taken into account.

The relations between the grain size and the surface roughness of work-pieces are shown in the following table

Grain No.	Surface Roughness (Ra/μm)
70/80-100/120	1.6-0.8
100/120-170/200	0.8-0.2
170/200-230/270	0.4-0.2

The recommended grain sizes for different grinding processes are shown in the following table.

Rough Grinding	70/80-120/140
Medium Grinding	120/140-200/230
Fine Grinding	200/230--M22/36
Polishing	M22/36 ---

Grain Size range: usually select grain size of 100/120----200/230 for Vitrified bonded.

The requirements to the grinding machine

The requirement of the vitrified CBN grinding wheel to the grinding machine is very high. The grinding machine should posses high stiffness, perfect aseismatic performance and thermal stability. And its principle axis should posses high accuracy, high rotating speed, axial displacement less than 3 μm and radial run out less than 5 μm . The feeding amount should be even and accurate, and the minimum feeding amount less than 2 μm /time.
