Vitrified Cubic boron nitride CBN grinding wheel for Crankshaft and
Vitrified CBN grinding wheel is used for grinding the end face,
piston ring, gasket, filling piece, compressor part, semiconductor
material, magnetic material, cutter, the stator of vane pump,
rotor, blade end, precision spring, etc.
1. large amount of grinding;
2. high wear resistance;
3. Good self-sharpening ability.
4. high grinding ratio;
5. need sufficient supply of coolant in the grinding.
6. in large scale production,usually use diamond rotary dresser for
1. The grinding of mild steel is the first choice. A lot of
experience on imported and domestic stainless steel and other soft
steel grinding to achieve very ideal results, and efficiency
increased by about 100%, economic benefits increased by 200%.
2. Precision and final grinding of workpieces (micro-bearings, air
machines, crankshafts, camshafts, high-precision threads,
instruments, etc.) produced in large quantities on automatic
3. The grinding of complex workpieces (gear shaper, broach, high
precision gear, die, punch, etc.) with good edge and angle
retention is required.
4. Fine grinding and final grinding of large precision workpieces
(machine tool guide, high precision lead screw, etc.). The common
abrasives used in these workpieces are easy to cause large
deformation because of high grinding temperature. The best choice
is CBN grinding wheel.
5. Fine and final grinding of precision parts made of
heat-resistant steel and alloy steel with high hardness (HRC55 or
above). When these parts are used with ordinary abrasives, high
accuracy can not be obtained because of abrasives consumption or
abrasive bluntness too fast.
6. Mass production of workpieces such as instruments and
micro-bearing parts on automatic or semi-automatic machine tools
7. CBN grinding for titanium alloy is the best choice of grinding
Ceramic bonded diamond CBN grinding wheel has more and more obvious
advantages in grinding some special materials such as ceramics, and
has a good prospect in the development of diamond grinding wheel.
It is considered to be a high-performance grinding wheel with high
speed, high efficiency, high precision, low grinding cost and low
environmental pollution. It has more and more extensive application
and has become a hot spot of research and development of grinding
tools all over the world in recent years.

|Choose Diamond or CBN grinding wheel?|
Diamond grinding wheel description:
Diamond grinding wheel is the best abrasive tools for grinding hard
Optical glass, gem and other stones, etc.
Diamond grinding wheel with high hardness and brittleness.
The diamond is easy to carbonization at 700 C ~800 C,
So it is not suitable for grinding steel which contains a lot of
CBN grinding wheel description:
CBN hardness is slightly lower than diamond,
But due to its thermal stability is good (1300 degrees ~1400, high
So it is not suitable for grinding steel.
CBN's thermal conductivity is around 46 times of corundum.
It has much longer service life than corundum grinding wheels.
So CBN is the best abrasive tools for grinding high hardness and
toughness metal material like Hardened steel, bearing steel,
high-speed tool steel, stainless steel, heat resistant steel and
|What grain size shall you choose?|
|For Diamond or CBN grinding wheel,150# is a medium rough grain size
which can meet|
the needs of most usages of you have no special requirement, if you
want to grind faster, choose a rougher grit,but it the surfacing
result will be rougher at the same time, how to achieve the goal
faster grinding and finer grit, choose two or three grit as a
group, use rough grit grind first, then finer grit.
|3 points for storage of grinding wheels|
Safety should be the utmost priority while doing any kind of work
like: storing grinding wheels.
These are to be handled with care
because bending and dropping can be a big problem.
For this, one needs to follow few rules In case causing any
The below-mentioned steps are to be followed:
1. Find a dry and spacious place for storing these wheels.
The place should be highly ventilated and the temperature should be
in the range of 10 and 30 degrees,
Both humidity and freezing water can lessen the density of grinding
wheels and cause a great damage.
It should also be kept in mind that the temperature in the storage
area should not be less than 4 degrees.
2. The grinding wheels should be stored on a straw mattress or a
soft surface for their safety.
Arrange the wheels column wise if there is a large number of
Keep the small grinding wheels on the top shelves while keeping the
heavier ones on the bottom.
The height should not be an issue while arranging the wheels on the
The cutoff wheels should be placed in flat position because an
upright or erected position can lead to distortion of the wheel.
3. Find the best suitable place for the storage that will not be a
problem in the later days.
It should be arranged in such a manner that you do not need to
rearrange them time and again.
The best way is to keep the heavier grinding wheels in the
warehouse while placing the opposite ones that is,
smaller ones and the ones you need almost every day on the shelf.
It will be easier to take these out.
