Understanding Cbn Wheel Compositions And Benefits
If you are a lathe tool user, you may have heard of cbn wheels and their advantages. In this section, we will explore what cbn wheels are, their compositions, advantages, and how they stack up against diamond wheels for lathe tools.
Definition Of Cbn Wheel
Cbn stands for cubic boron nitride, a synthetic crystalline material that is second only to diamond in hardness. A cbn wheel is a grinding wheel made from this material, used for sharpening and shaping cutting tools like lathe tools.
Compositions Of Cbn Wheel
Cbn wheels can be made in two main compositions: resin and metal bond.
Resin Bond Cbn Wheel
- Made using a phenolic resin matrix.
- Good for sharpening and shape correction because of their ability to handle intricate shapes.
- Have a relatively low heat tolerance, with a maximum speed of 6,000 surface feet per minute.
- Can require frequent dressing.
Metal Bond Cbn Wheel
- Made using a metallic matrix, usually bronze.
- Longer wearing and more durable than resin bond.
- Can operate at higher speeds of up to 20,000 surface feet per minute.
- Better heat conductivity, which means less heat buildup during use.
The Advantages Of Cbn Wheel
Cbn wheels have several advantages over other types of grinding wheels for lathe tools.
- Longer lifespan: Cbn wheels last longer than other grinding wheels, which means fewer replacements and lower costs in the long run.
- Consistency: Cbn wheels maintain their shape and size better than other wheel types, leading to consistent tool edges and shapes.
- Higher material removal rates: Cbn wheels grind faster than most other abrasive grains.
- High precision: Cbn wheels can sharpen cutting tools with high precision and accuracy.
Analyzing The Diamond Wheel Vs. Cbn Wheel For Lathe Tools
When it comes to choosing between diamond wheels and cbn wheels for lathe tools, both have their advantages and disadvantages.
- Better for grinding harder materials like carbide.
- Usually more expensive than cbn wheels.
- Can handle higher speeds than cbn wheels.
- Better for grinding softer materials like high-speed steel.

Understanding the compositions and benefits of cbn wheels is essential for lathe tool users looking to choose the right grinding wheel for their needs. While both diamond wheels and cbn wheels have their advantages, cbn wheels are typically more cost-effective over time and provide consistent and precise sharpening outcomes.
Introduction Of What Grit Cbn Wheel For Lathe Tools?
Lathe tools are a significant investment and require adequate maintenance to function optimally. Using the right grinding wheels for your lathe tools can make all the difference in achieving the desired results. We delve into understanding grit in cbn wheels and why it is essential to select the right grit for your lathe tools.
Overview Of Grits In Cbn Wheels
Cbn wheels are grinding wheels that consist of cubic boron nitride particles. They are highly durable and can sharpen hardened steel and carbide. Grit size in cbn wheels refers to the size of the abrasive particles used in the wheel manufacturing.
Cbn wheels’ grit size typically ranges from 80 – 1000 grits, with larger grit sizes being ideal for rough grinding, while finer grit sizes work better for finishing and polishing.
Reason Why Grit Is Essential For Cbn Wheels
The grit size in a cbn wheel determines the surface finish quality of your lathe tools, the amount of material removed, and the grinding wheel’s cutting ability. Choosing the right grit size can affect the overall performance of your lathe tools.
Coarser grit sizes on cbn wheels tend to remove more material quickly, while finer grit sizes deliver smoother finishes.
The Importance Of Selecting The Right Grit For Your Lathe Tools
Selecting the right grit size for your lathe tools influences the desired results you want to achieve. Using the wrong grit size can lead to poor finishes, premature wear of the lathe tool’s edges and reduce the tool’s life. In contrast, using the correct grit size improves the grinding quality and extends your lathe tools’ life, saving you money in the long run.
What Are The Common Grits For Lathe Tools?
Several grit sizes are suitable for lathe tools, and selecting one depends on what you’re trying to accomplish.
- 80 grits: Suitable for rough grinding and shaping
- 180 grits: Excellent for sharpening chisels and tools
- 220 grits: Used for smoothing the grinding marks left by coarse grits and preparing the tool’s edge for a fine grit wheel
- 350 grits: Great for fine grinding and achieving smooth finishes.
- 600 to 1000 grits: Often used for honing the sharp edges of lathe tools and polishing them to a mirror finish.
Selecting the right grit size in cbn wheels is crucial for maintaining and prolonging the life of your lathe tools. Remember to always choose the right grit size depending on the task ahead and to ensure consistent results.
Factors To Consider When Choosing The Grit For Cbn Wheels
When it comes to choosing the right grit for cbn wheels for lathe tools, there are several factors that need to be considered. These factors include the type of lathe tool, the hardness of the material being turned, the finishing requirements of the lathe tool and cost considerations.
The Type Of Lathe Tool
The type of lathe tool being used is an important factor when considering which grit cbn wheel to choose. Different types of lathe tools have different requirements when it comes to grit.
- Roughing tools: These tools require a coarse grit cbn wheel to remove large amounts of material quickly.
- Finishing tools: These tools require a finer grit cbn wheel to achieve a smoother finish.
- Sharpening tools: These tools require a very fine grit cbn wheel to achieve a sharp edge.
The Hardness Of The Material Being Turned
The hardness of the material being turned is another important factor to consider when choosing the grit for cbn wheels. Hard materials such as steel require a finer grit cbn wheel to avoid overheating and damage to the tool. Softer materials such as wood or plastics can use a coarser grit cbn wheel without risk of damage to the lathe tool.
The Finishing Requirements Of The Lathe Tool
The finishing requirements of the lathe tool are also a key consideration when choosing the grit for cbn wheels. If a smoother surface finish is required, then a finer grit cbn wheel should be used. If a rougher surface finish is acceptable, then a coarser grit cbn wheel can be used.
Finally, cost considerations are an important factor when choosing the grit for cbn wheels. Generally, coarser grit cbn wheels are less expensive than finer grit wheels. However, finer grit wheels typically last longer than coarser grit wheels, so cost should be considered in terms of the overall lifespan of the cbn wheel.
Choosing the right grit for cbn wheels for lathe tools requires careful consideration of several factors. By taking into account the type of lathe tool, the hardness of the material being turned, the finishing requirements of the lathe tool, and cost considerations, you can ensure that you select the best grit for your specific needs.
