Characteristics of Ceramic Bonded CBN Grinding Wheel:

1. Ceramic bonded CBN wheel has controllable porosity. Especially, it is very important for CBN grinding wheel to grind steel. It is helpful to remove the grinding debris from the grinding area and avoid the blockage of the grinding wheel. At the same time, it can provide a channel for the coolant to reduce or avoid grinding.

2. CBN wheel has excellent free cutting performance and high material removal rate. The grinding force of the grinding wheel is small and the grinding performance is good.

3. The good heat resistance of vitrified bond makes full use of CBN abrasive, and the service life of grinding wheel is longer. However, the resin binder can not keep the abrasive particles effectively at about 200 ℃.

4. Ceramic bonded CBN grinding wheel has small thermal expansion coefficient and good rigidity, which is suitable for high precision and low roughness grinding.

5. Ceramic bonded CBN grinding wheel is easy to be trued, and can be corrected and sharpened at one time with low maintenance cost.

6. CBN wheel with ceramic bond has better self sharpening property, longer dressing interval and less dressing frequency.

7. CBN wheel has good chemical stability and wide adaptability to grinding fluid.

8. CBN grinding wheel with ceramic bond has good surface integrity, high quality and long service life.

Tongyu Industrial focuses on the development of various types of grinding wheels, such as internal grinding wheel, external grinding wheel, double face grinding wheel, camshaft grinding wheel, surface grinding wheel and so on. The products are suitable for grinding of high hardness and difficult to machine materials such as high manganese steel, high alloy steel, all kinds of cast iron, all kinds of hardened steel, gears, bearings, rolls, molds, cylinder liners, glass, gemstones, etc. they are widely used in mechanical manufacturing, hydraulic, bearing, compressor and other fields.

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.

Specification and size: abrasive, particle size, binder, outer diameter, thickness, inner diameter, abrasive working layer width, substrate thickness, etc. purpose: workpiece name, cutting size, cutting material;

Service conditions of grooving and cutting: machine tool, grinding wheel speed, feed speed and cutting depth;

Dry and wet cutting requirements: cutting accuracy, chipping requirements, processing surface integrity, etc

Special requirements: whether the tool is assembled and used, whether the resin cutting wheel needs to conduct electricity, whether the outer circle of the cutting wheel has a water tank, the size and quantity of the water tank, whether there is a chip removal groove on the outer side of the cutting wheel base, etc.
