CBN grinding wheel for Valve grinding

1. Electroplated bond CBN grinding wheels are used for the forming grinding of the engine lock slot, neck, tapered surface, and the end surface of the engine valve, as well as the cutting off and multipart processing, including valve groove wheel, Valve tip end grinding wheel, Chamfering wheel for round shaft and tube, valve head &seat grinding tool, valve cut off wheel.

The maximum working linear velocity can reach 180 m/s, belonging to creep slowly forming grinding. Grinding wheels and work-piece have large contact areas and high-speed ratio, can achieve a high material removal rate, improve machining efficiency and reduce machining costs enormously, and do not need a trim. The contour accuracy of the workpiece: is 0.01 mm, and the base of the grinding wheel can be recycled.

Suitable for processing: 40 Cr, 4Cr9Si2, 4Cr10Si2Mo, 21-4N, 23-8N and other ordinary alloy steel and heat-resistant alloy steel

Electroplated bond CBN grinding wheels are a popular choice for valve grinding because they are highly efficient and can produce accurate, high-quality results. CBN stands for cubic boron nitride, which is a superhard material that is second only to diamond in terms of hardness.

The electroplated bond CBN grinding wheel consists of a layer of CBN abrasive particles that are electroplated onto a metal substrate. The CBN abrasive particles are evenly distributed and firmly bonded to the substrate, which allows the grinding wheel to maintain its shape and dimension throughout its life.

One of the advantages of using an electroplated bond CBN grinding wheel for valve grinding is that it can achieve high material removal rates while generating minimal heat. This is important because excessive heat can cause the valve to distort or warp, which can affect its performance.

In addition, electroplated bond CBN grinding wheels are highly wear-resistant and can maintain their shape and size even after prolonged use. This means that the grinding wheel will require less frequent dressing and will have a longer service life, which can reduce overall grinding costs.

When using an electroplated bond CBN grinding wheel for valve grinding, it is important to select the appropriate grit size based on the material being ground and the desired surface finish. Additionally, the grinding parameters such as grinding speed, feed rate, and coolant flow rate should be optimized for the specific application to ensure the best results.

2. Vitrified bond CBN grinding wheels are another popular choice for valve grinding because they offer a high level of precision and control. Vitrified bond CBN grinding wheels are made by mixing CBN abrasive particles with a vitrified bond material and then firing the mixture in a high-temperature kiln.

The vitrified bond material is a ceramic that is highly porous and has excellent bonding properties, which allows the CBN abrasive particles to be evenly distributed throughout the grinding wheel. The porous structure of the vitrified bond also allows coolant to flow freely through the grinding wheel, which helps to prevent heat buildup and improve grinding performance.

One of the advantages of using a vitrified bond CBN grinding wheel for valve grinding is that it can produce very smooth and precise finishes. Vitrified bond CBN grinding wheels are also highly wear-resistant and can maintain their shape and size for longer periods of time than other types of grinding wheels.

When using a vitrified bond CBN grinding wheel for valve grinding, it is important to select the appropriate grit size based on the material being ground and the desired surface finish. Additionally, the grinding parameters such as grinding speed, feed rate, and coolant flow rate should be optimized for the specific application to ensure the best results.

Overall, vitrified bond CBN grinding wheels are a good choice for valve grinding applications that require high precision and surface finish quality. However, they may be more expensive than other types of grinding wheels, so their cost-effectiveness should be evaluated based on the specific application requirements.

3. A metal bond CBN (cubic boron nitride) grinding wheel is a type of grinding wheel that uses a metal bond to hold the CBN abrasive particles in place. CBN is a superhard material that is second only to diamond in terms of hardness, making it ideal for grinding hard materials such as ferrous metals, including valves.

Valve grinding involves removing material from the surface of the valve and/or the valve seat in order to improve their sealing performance. A metal bond CBN grinding wheel can be an effective tool for this task, as it can grind quickly and efficiently while maintaining its shape and holding its abrasive particles in place.

When selecting a metal bond CBN grinding wheel for valve grinding, it is important to consider factors such as the size and shape of the valve and valve seat, the material being ground, and the desired finish. A professional in the field will be able to help you select the appropriate grinding wheel for your specific needs.

It is also important to use proper safety precautions when using any type of grinding wheel, including wearing eye protection, a dust mask, and other appropriate safety gear.
