Vit CBN Grinding Wheel For Gear Hob Grinding
CBN super hard grinding wheel for hob deep hole grinding
We customize the production of a special gear wheel hob hole,
broach hole with cubic boron nitride CBN grinding head (grinding
Diamond and CBN cubic boron nitride wheels are used for end
grinding. The outer circle is very thin and can be ground to the
bottom of the cutting edge.
The two materials of grinding wheel wear resistance is very good,
low loss during grinding, suitable for dry grinding environment and
wet grinding environment.
The commonly used granularity is 60 mesh, 80 mesh, 120 mesh, 150
mesh and 180 mesh (the knife edge with high finish requirements can
be customized finer granularity), the coarser granularity grinding
will be more sharp, the knife edge finish is slightly worse.
Finer grain is the opposite.
The external diameter of grinding wheel is from 50mm to 500mm,
which can be customized according to different requirements of
customers and processing technology design.

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 Vit 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
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
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
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.
