Selection of grits is based on the years of sharpening in our workshop. We experimented grinding knife bevels with coarse CBN wheels on Tormek, grits from #80 to #360, and found out that the #160 grinds way faster than #200 and over, not shredding the knife edge as do grits under #100 - the #160 has become our choice for beveling.
3.Cubic boron nitride (CBN) grinding wheel selection The cubic boron nitride (CBN) grinding wheel is most suitable for processing hard-to-machine steel with high hardness, high viscosity, high-temperature strength, and low thermal conductivity, and high speed or ultra high speed grinding. Its application range complements synthetic diamond.
PCD(Polycrystalline diamond) cutting tools can outperform by carbide by a ratio 30-50times as well as it can get a better surface finishing than carbide. The best quality of sharpened edge of the PCD tools can achieve the excellent tool life which is certainly reduces the unit cost in present white-hot cutting tools market. MORESUPERHARD provide private custom PCD cutting, …
Main information for the selection of grinding wheel. To choose the parameters of grinding wheel the following information is needed: About the part to be ground - type, shape and part parameters (tread pitch, gear model) and other; the material of the part - type of steel, brand, heat treatment, hardness; the required surface finish, Ra (pm).
Check the "Diamond & CBN Wheel Selection Table (reference)" below for more information on selection methods by work material type and grinding methods. Considering the letter "N" as the median value, it is typical to select "L" when soft binding and a sharp wheel are required, and conversely "P" when hard binding and a long wheel life are required.

Sort by Date.. 1 A Wheel Selection Technique for Form Gear Grinding (May/June 1986). Until recently, form gear grinding was conducted almost exclusively with dressable, conventional abrasive grinding wheels.
CBN wheel grit selection? Hello! As a woodworker, I have wanted a CBN grinding wheel for a long time now, and as I get more into turning I am getting more serious about pulling the trigger. I am only willing to throw down for one wheel so I am naturally wondering what grit wheel would serve best to grind my woodworking tools AND sharpen turning ...
A CBN grinding wheel uses Cubic Boron Nitride, or CBN, as its grinding material. Cubic Boron Nitride is considered a super abrasive. As the name suggests, super abrasives are stronger than normal abrasives like Aluminum Oxide and Silicon Carbide. CBN is best used to grind hard metals like: Steels with a hardness rating of at least 45Rc
3. Selection of Cubic Boron Nitride (CBN) Grinding Wheel. The cubic boron nitride (CBN) grinding wheel has only a thin layer of cubic boron nitride particles adhered to the surface of the ordinary grinding wheel. Its abrasive grain toughness, hardness and durability are 100 times that of corundum grinding wheels.
Diamond and CBN grains Grinding and dressing grits made of diamond (DIA) or cubic boron nitride (CBN) are used in modern grinding technology. While diamond is avail-able in natural or synthetic form, CBN is a purely synthetic product. What they have in common is the cubic crystalline structure and the associated physical characteristics
The life of CBN grinding tools can be recommended by significantly increased by using pure oil. In any case an emulsion with an oil concentration as manufacturer should be used. CUTTING FLUIDS Cutting fluids should be used whenever possible while using diamond wheels to reduce the heat generated by grinding and extend the wheel's life.
Grinding is defined in the German Industrial Standard DIN 8589 as abrasive cutting with geometrically unspecified cutting edges. All grinding wheels with an abrasive layer of diamond or cubic boron nitride (CBN) are grinding tools in the sense of DIN 8589. Their "cutting edges" are formed by the abrasive grits diamond or CBN.

Selection of Cubic Boron Nitride Grinding Wheel. There is only a very thin layer of cubic boron nitride particles sticking on the surface of CBN grinding wheel,but its toughness,hardness,durability is about 100 times more than corundum grinding wheel,extremely suitable for hard-to-grind steel materials.
The study at GE suggests cBN grinding of carburized parts and hardened parts can impact additional residual compressive stress to the part surface. These stresses may be as little as 30% greater to as much as 250% greater than the heat treated surface stresses (Ref. 3). Less tensile stress and more compressive stress equals stronger gear teeth.

CBN grinding wheels are used to sharpen, cut, or remove metal from hard surfaces. Use these wheels when you need a good consistent finish. Most notably CBN wheels are used to cut HSS metals, like wood tools, blades, bits, and cutters. This type of steel is better than the older high-carbon steel because it can withstand higher temperatures.
