Buying Guide for CBN Grinding Wheels for Woodturners
1. Wheel Diameter and Width
Wheel sizes typically range from 6 to 8 inches diameter, with widths between 1” to 1.5”. Larger diameter wheels provide more grinding surface and better heat dissipation, which is beneficial for sharpening wider tools or multiple tool styles. Choose a width that suits your grinder and the tools you sharpen.
2. Grit Level
CBN wheels come in various grit levels, commonly 80 and 180 grit for woodturning. 80 grit wheels suit rough sharpening and heavy material removal, while 180 grit provides a finer edge for finishing and honing tool edges. Some woodturners use multiple wheels to cover all sharpening needs.
3. Bore Size Compatibility
Ensure the wheel’s bore size matches your grinder arbor. Common bores are 1/2 inch and 5/8 inch. Using the correct bore prevents wobbling and ensures secure mounting, which improves sharpening precision and safety.
4. Material and Structure
Aluminum-core wheels are lighter and tend to run smoother than steel-core wheels, reducing vibration during sharpening. Solid steel wheels offer durability and stability but weigh more. Nickel plating on wheels can enhance longevity and resistance to wear.
5. Maintenance and Dressing Requirements
One of the main advantages of CBN wheels is their minimal maintenance. They typically do not require dressing, saving time and effort over traditional abrasive wheels. Look for balanced wheels that maintain their shape over time to avoid frequent jig adjustments.
6. Speed Ratings
Match wheel speed ratings with your grinder’s operational speed. CBN wheels generally perform well between 1000 and 3600 RPM, depending on their size and manufacturer recommendations.
7. Specialized Features
Some wheels offer unique edge designs such as radius edges for hollowing tool bits and scrapers. Consider your specific woodturning tool types and whether you need specialized sharpening profiles to increase efficiency.
