800mm Ceramic Grinding Wheel Automobile Engine Crankshaft Camshaft

Product Specification

Ceramic CBN Grinding Wheel Special For Crankshaft And Camshaft Of Automobile Engine

Model Type: TYC-GW-013

Grinding workpiece: automobile engine 

Workpiece material: cast iron

Workpiece hardness: HRC 30-72

Processing requirements: roughness Ra0.1

Diamond wheel and CBN wheel have their own characteristics. Different characteristics are suitable for different workpiece materials. Selecting unsuitable abrasive particles will produce residual stress or it is difficult to obtain the expected grinding performance. According to the continuous research on the material and processing requirements of automobile engine crankshaft and camshaft, Henan Amos superhard grinding tool has developed a special cylindrical grinding wheel, which has achieved good grinding effect.

Scope of application:

It is suitable for domestic high-precision CNC cam grinder such as high-efficiency and powerful grinding of automobile engine camshaft / crankshaft. The cam grinding wheel produced by our company can also be used with precision CNC cam grinding machines produced by other grinding machine manufacturers at home and abroad.

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.
