Product Description
Electroplated Cubic Boron Nitride (CBN) Grinding Wheel For Gear Hob Cutter This type of CBN grinding wheels are special used for gear hob cutter grinding,
before grinding,we need to use Green silicon carbide grinding wheel dress it,to make sure it has good concentricity.
During grinding,if you find the CBN wheel you are using is a little bit hard, you should slow down the line speed from 40m/s to 30m/s.
The roughness and sharpness is the most important for the CBN wheels.
Application of Vit CBN Grinding Wheel For Gear Hob Grinding
Gear hob used in processing gear, sprocket, turbine and spline etc., to withstand the effect of impact load and in the manufacturing process of wear and tear, so the hardness requirements to HRC63-66 degrees, the material is commonly high speed steel (such as W18Cr4V W9Mo3Cr4V, W6Mo5Cr4V2, etc.).
Why choose CBN Grinding Wheel For Gear Hob Grinding
The inner hole of high speed steel hob will be deformed after carburizing heat treatment. The unilateral deformation will range from 0.1 mm to 0.25 mm, and the surface hardness can reach above HRC60 degrees.
After heat treatment, the surface hardness of hob is relatively high. Usually, grinding wheel is used for inner hole grinding in the later stage.
General high speed steel hob body is relatively long, the hole is relatively deep (such as hole depth in 150 mm to 200 mm, some may exceed 200 mm depth).
Grinding with corundum grinding wheel will encounter excessive wear of grinding wheel, difficult to master the size, hole grinding out will have the problem of taper.
It is recommended that users use cubic boron nitride (CBN) grinding wheel to grind holes.
Wheel hob grinding inner hole of cubic boron nitride (CBN grinding wheel) there are several different processes of producing method, this is according to customer's specific process to set, such as the use of grinding machine is high speed or low speed grinder, in theory belongs to low speed grinding machine speed is lower than 10000 turn, more than 40000 to a high speed, another factor is hob grinding inner hole machining allowance and finish requirement.
Different machining processes have different processes of grinding wheel to deal with, there is no general only applicable.
Choosing the wrong grinding wheel will result in low processing efficiency, long processing time and taper of the deep hole grinding.
Our company can provide suitable CBN grinding wheel according to different hob aperture, depth and finish requirements and different types of grinding machines. Welcome to consult.

Advantages Of Our Vit CBN Grinding Wheel For Gear Hob Grinding
Our company produces single beveled diamond grinding wheel (suitable for grinding carbide hob) and CBN cubic boron nitride grinding wheel (suitable for grinding high speed steel hob of various materials) for hob grinding.
The working layer width of the grinding wheel of the two materials is generally between 3mm-5mm, and the thickness is between 2mm.
(this design is because the hobbing blade tooth is short, and the narrower the working layer of the grinding wheel, the sharper the grinding will be. The wider the grinding resistance will be, and the worker will feel that the grinding of the grinding wheel is not sharp.)
Grinding wheel Angle is generally around 15 degrees (special requirements can be customized).
Cubic boron nitride CBN for short, belongs to the superhard material, hardness is second only to diamond, good heat resistance, made after grinding wheel grinding performance, not only qualified for grinding hard materials processing, improve the production efficiency, and to strictly control the shape and size precision of the workpiece, can effectively improve the quality of grinding workpiece, improve workpiece surface integrity after grinding, thus increasing the fatigue strength of the parts, prolong the service life and increase the reliability.
