Application range of ceramic CBN grinding wheel

1. The grinding of mild steel is very important. The ceramic CBN grinding wheel can grind all kinds of stainless steel and other mild steel very well, which is 4-6 times of the ordinary grinding wheel's processing efficiency and 8-10 times of the ordinary grinding wheel's service life.

2. Precision grinding and final grinding of workpieces (micro bearing, air compressor, crankshaft, camshaft, high precision thread, instrument, etc.) produced in large quantities on automatic machine tools.

3. Grinding of complex surface workpieces (gear shaper, broach, high precision gear, copying die, punch, etc.) with good edge and angle retention of grinding wheel is required.

4. Fine grinding and final grinding of large precision workpieces (machine tool guide, high precision lead screw, etc.). Because of the high grinding temperature, these workpieces are easy to cause large deformation when using ordinary abrasives.

5. Fine grinding and final grinding of precision parts made of heat resistant steel and high hardness alloy steel (above HRC55). These parts can't get high precision because of the consumption of grinding tools or too fast grinding.

6. For special steel such as tungsten, tungsten molybdenum high speed steel, vanadium alloy steel, cobalt alloy steel, special high speed steel tool grinding, difficult to machine heat-resistant steel workpiece superfinishing, and other steel quenching tools honing.

7. Grinding and precision of special high speed steel tools including tungsten, tungsten molybdenum and other high speed steel, especially vanadium alloy steel and cobalt alloy steel.

8. Mass produced workpieces on automatic or semi-automatic machine tools, such as instruments and miniature bearing parts.

9. CBN grinding wheel is the best choice for grinding ceramic on titanium alloy.

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.
