Model Type: TYC-GW-014
Sample Specification: 630*300*40 (Out Diameter * Inner Hole * Thickness)
Bearing steel is used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as
well as high elastic limit. When grinding with ordinary abrasive wheel, the consumption of
grinding wheel is very fast, the grinding temperature is very high,
and the surface of workpiece is easy to produce defects such as
cracks, which seriously affect the surface quality of workpiece
grinding.
Solution for grinding high vanadium high speed steel:
In order to improve grinding efficiency and grinding surface
quality, We has done a lot of work in the selection of grinding
wheel abrasive types, bond, hardness, abrasive particle size,
optimization of grinding parameters and improvement of grinding
fluid, and achieved good results. A ceramic bonded CBN grinding
plate has been developed for this material.
The Advantages of Ceramic bonded CBN grinding disc:
1. CBN grinding disc with ceramic bond has a large number of pores,
which can play the role of chip holding and chip removal, so as to
reduce the blockage of the grinding wheel, and promote the grinding
fluid to cool the grinding area fully, which is conducive to
reducing the temperature of the grinding area and improving the
grinding performance.
2. CBN grinding disc with ceramic bond has high temperature
resistance, strong abrasive wear resistance and high grinding wheel
strength, so this kind of grinding wheel is suitable for high speed
and high precision grinding.
3. The bond of CBN grinding plate is brittle and hard, with pores, so
it is easy to repair, which is conducive to popularization and
application.
Our Tongyu Industry focuses on the development of ceramic bonded
grinding wheel, mainly engaged in a variety of specifications and
models of surface grinding wheel, cylindrical grinding wheel,
internal grinding wheel. The products are suitable for grinding of high hardness and
difficult to machine materials such as high speed steel, high
manganese steel, high alloy steel and all kinds of hardened steel.
They are widely used in machining fields such as mechanical
manufacturing, gear, bearing, roll, mold, hydraulic pressure,
compressor, etc.
Main features of CBN grinding wheel:
High grinding efficiency
High wear resistance: the wear resistance of the grinding wheel is
high, and the abrasive consumption is small, especially when
grinding hard and brittle workpiece.
Low grinding force and low grinding temperature
The workpiece has high precision, high finish and good shape
retention

Brief Introduction of CBN Products:
Cubic boron nitride (CBN) grinding wheel has only a very thin layer
of CBN particles adhered to the surface of ordinary grinding wheel.
The toughness, hardness and durability of CBN particles are 100
times higher than those of corundum grinding wheel. CBN grinding
wheel is suitable for machining hard to grind steel with high
hardness, high viscosity, high high temperature strength and low
thermal conductivity, and for high speed or ultra high speed
grinding.
When grinding steel, especially special steel, the effect of
diamond grinding wheel is not obvious. The grinding efficiency of CBN wheel is about 100 times higher than
that of corundum wheel and five times higher than that of diamond
wheel, but the grinding efficiency of CBN wheel is lower than that
of diamond wheel.
The selection of CBN grinding wheel is similar to that of diamond
grinding wheel. But in the selection of bond, most of them are resin bond. Ceramic bonded CBN wheel is mainly used for grinding titanium
alloy, high speed steel, malleable iron and other difficult to
process ferrous metals. Resin bonded CBN wheel is suitable for
grinding ferromagnetic materials, which is an ideal choice for
processing steel.
CBN grinding wheel concentration is generally in the range of ~
150%, which is more economical and reasonable. It can not use
ordinary cutting fluid, but needs special cutting fluid or dry
grinding.
Precautions for use:
Please check carefully before installing the cutting wheel. If
there is any gap or other damage, please stop using it.
When the cutting wheel is marked with the rotation direction, it
should be consistent with the rotation direction of the machine
tool. On the contrary, the cutting is not sharp, and it is difficult to
give full play to the performance of the cutting wheel.
Please do not use the cutting wheel that does not meet the
requirements.
If any abnormality is found in the cutting process, stop the
machine immediately and check the cause.
When the cutting is not sharp, the grinding wheel should be
trimmed. If it is used continuously, the grinding wheel may be damaged due
to overheating and overload.
When the grinding wheel rotates, it is strictly forbidden to cut by
hand, let alone touch the sand by hand and body
The cutting wheel is forbidden to be used in operations other than
grooving or cutting, so as to avoid abnormal operation due to
uneven stress.
