How to Choose the Best CBN Wheel

Introduction

Choosing the right CBN grinding wheel is essential for achieving optimal performance and efficiency in your machining operations. Whether you're working in aerospace, automotive, or tool manufacturing, selecting the right wheel involves considering several factors, such as the type of bond, the intended application, and the wheel size. 

What Type of Wheel Should I Buy?

When selecting the best CBN grinding wheel for your application, consider the following:

• What type of bond does my CBN wheel need?
• What will I be using the CBN wheel for?
• What will I be making with the CBN wheel?
• What size CBN wheel will I need?

Answering these questions will help ensure that your CBN wheel is perfectly suited to your specific requirements.

What Are the Different Types of Bonds?

Resin Bond

• Characteristics: The most common bond system used. It offers good elasticity, superior surface finish, and highly efficient grinding performance.
• Applications: Ideal for general-purpose grinding applications and provides a balance between performance and longevity.

Hybrid Bond

• Characteristics: Designed to meet the high demands of endmill manufacturing on CNC machines. It features a lower spindle load, excellent thermal stability, reduced tool deflection, longer spindle life, and less heat transfer compared to resin bond wheels.
• Applications: Perfect for high-precision and high-demand grinding operations.

Vitrified Bond

• Characteristics: Extremely aggressive and provides an excellent tool for tough grinding surfaces.
• Applications: Suitable for grinding automobiles, bearings, gears, camshafts, and crankshafts. This bond is versatile and can be used for a wide variety of grinding applications.

At Eagle, we manufacture these bonds and many others to cater to various grinding needs.

Which Wheel Will Last the Longest?

All Eagle wheels are engineered to provide excellent wheel life without sacrificing the ability to grind aggressively. Proper care and maintenance of your CBN wheels will ensure they last a very long time. We specialize in creating wheels that deliver long-lasting performance and efficiency.

Why Should I Use CBN Wheels and Not Diamond Grinding Wheels?

CBN, or cubic boron nitride, is a man-made material that rivals the strength of diamond. The structure of CBN replaces carbon atoms in diamonds with boron atoms, allowing CBN wheels to grind ferrous materials with ease. CBN wheels are ideally suited for hardened steels due to minimal heat buildup during grinding. This makes them an excellent choice for applications involving hardened steels and other ferrous materials.

Conclusion

Choosing the right CBN grinding wheel is critical for achieving superior grinding performance and efficiency in your operations. By considering the type of bond, the intended application, and the wheel size, you can ensure that your wheel is perfectly matched to your needs.
