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.

Ordering instructions:

When you order for the first time, please provide the following parameters, so that we can help you choose the most suitable cutting wheel.
