CBN Grinding Wheel
Cubic Boron Nitride(CBN) grinding wheels are a revelation for the sharpening of HSS turning tools. CBN abrasive is a similar product to synthetic industrial diamonds, but a CBN wheel is far better suited for sharpening high speed steels and will withstand the friction from grinding with much less heat produced than with a diamond wheel. They produce hardly any sparks, cut quickly and efficiently and will last for many years. Plus, because it will withstand the friction the wheel doesn't wear and therefore the jig will not need to be reset. No dressing is required and they leave a nice fine and even sharp edge.
What is a CBN Grinding Wheel?
ACBN wheelis made from cubic boron nitride. This material is one of the hardest materials available, second only to diamonds. The main feature of the material is that it features a high abrasion resistance and thermal conductivity that maintains its sharp cutting edges. It’s a great choice when doing advanced products that require a high attention to details.
Why Use This Type of Wheel?
CBN wheels are important for grinding HSS. This is because it's a better material for sharpening and for durability, one of the best available. Diamond is harder than CBN, but over time many people have discovered that diamond is not a suitable abrasive grain and isn’t a good choice when grinding on high speed dry wheels. Choosing to buy grinding wheels with cubic boron nitrate will offer you the durability you need, while giving you the finished product you desire.

Benefits of CBN Grinding Wheels
These types of wheels have an almost indefinite life span when they are properly cared for. Many have chosen to use these wheels instead of the normal granular wheel because of their durability. The strong nature of the wheels comes from the bonding that takes place between the grains and the supporting steel hub. Thanks to this bonding feature, the wheels can be used dry without any coolant. Only a small amount of pressure is needed to sharpen a tool. The grind is very fine and there are almost no sparks when used for sharpening, unlike similar grinding wheels. The wheel remains cooler than a conventional wheel as well, making it nearly impossible to burn the tools.
