CBN wheels
I'm thinking about buying a 6" CBN wheel for my cheapo 6" Ryobi bench grinder. I'm thinking about getting it on Amazon. For sure it will be Chinese and be around $40 -60.
Any thoughts? Is it worth it?

Yes, CBN grinding wheels from China can be good, but quality can vary. While some may be of excellent quality, others may have issues with balance, durability, or performance. It's important to choose reputable manufacturers or sellers to ensure you're getting a quality product.

Factors to Consider:
Yes, CBN grinding wheels from China can be good, but quality can vary. While some may be of excellent quality, others may have issues with balance, durability, or performance. It's important to choose reputable manufacturers or sellers to ensure you're getting a quality product.
Here's a more detailed look:
Factors to Consider:
- Manufacturer Reputation:
- Like any product, reputation matters. Reputable manufacturers, even if they are from China, are more likely to produce consistent, high-quality wheels.
- Wheel Type:
- Ensure you're getting the correct type of CBN wheel for your application (e.g., electroplated vs. resin bond).
- Grit and Specification:
- Choose the correct grit and specification for your grinding needs.
- Balance:
- A well-balanced wheel is crucial for smooth and efficient grinding, so check reviews for issues with wobble or imbalance.
- Durability:
- CBN wheels should last a long time, especially with proper care and use. Consider reviews about the longevity of the wheels.
- Cost:
- While CBN wheels can be expensive, consider the long-term value and cost savings compared to other abrasives.
Tips for Buying:
-
Read Reviews: Look for reviews from other users, especially those who have used the specific wheel you're considering.
-
Check Seller Reputation: Ensure the seller is reputable and has a good track record.
-
Contact the Manufacturer Directly: If you have specific questions or concerns, don't hesitate to contact the manufacturer directly.
In conclusion, while CBN wheels from China can be a good option, it's important to be discerning and choose products from reputable sources to ensure quality and performance.

I don’t know if you’re supposed to use a CBN wheel on a full speed grinder. I thought they were really only designed for slow speed? I could be wrong.
Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".
Thanks for all the input Oldtool!
Thanks Ryan... you make a good point. I'll check that out.
CBN (Cubic Boron Nitride) grinding wheel is very suitable for use on high-speed grinding machines. CBN is a synthetic material with a high hardness. CBN wheels are designed to grind HSS and other metals with a hardness above 54 HRC (Rockwell scale). Do not use with softer materials.
The wheel has a steel base with a CBN coating. The steel base prevents the wheel from deforming. The wheel also does not need to be flattened and does not produce dust, unlike bonded stones. CBN wheels last a very long time, provided you use the wheel correctly.
CBN wheels remove material very effectively. Little force is needed to achieve a sharp result. Use minimal pressure when grinding to prevent the wheel and your material from overheating. You apply the right amount of pressure when the material is barely warm.
Use CBN grinding stones dry, so without water. You can use the wheel on your bench grinder or on your wood lathe with a speed between 1400 and 3000 rpm. (Dia 150) Use a suitable adapter sleeve for your machine. When using a arbor on the lathe, a speed of 1700-2000 rpm is recommended.
In all Far east offers I read mostly CBN diamond. That makes me wonder what is it. Is it CBN or is it diamond or are they using the terminology wrong. In short I don't know what I'm buying.
I think this is where I got mine from, but maybe not…it’s been a while. It’s a good explanation, none the less.
