Wheel Design Geniuses

John said “Just wanted to let you know the special cup wheel works great, ya’ll are wheel design geniuses.!”  


“Truly a quality product”

Tim said “…..I’m very pleased with the performance of your wheel. I will order more wheels as I need them. Truly a quality product! Thank you!


“I much prefer your wheels”

Brant says “I much prefer your wheels than anyone else that I have dealt with!”


This wheel is a beast…..

Eaven Says…… So far with the wheels that I have ordered;   3mm X 75mm Diamond Fluting wheel This wheel is a beast I have only good things to say about it. 100% satisfied   100mm X 10mm CBN This wheel along with my programing has done exactly what I have set out to do […]

Great Looking Wheel

Susan said “We received your wheel-Thank you! Everything looks very nice, actually beautiful, and we look forward to having it tested!”


For Grinding PCD (Polycrystalline Diamond) and PCBN (Polycrystalline Cubic Boron Nitride) a vitrified bond is typically specified by tool makers and re-sharpeners.

The bond system incorporates sintered vitreous materials with carefully selected diamond / CBN powders and coatings to provide both a mechanical and chemical bonding of the abrasive particle to the bond structure, thereby resisting premature Diamond / CBN pull out. The wheel structure also incorporates induced porosity to aid with coolant delivery to the point of grind and to help the wheel to resist getting loaded up during use.

Vitrified bond wheels offer tool life greater than 150 times that of a resin bond wheel and can be easily trued and dressed on the machine.

Typical grit sizes for rough grinding are D22 Micron and for finish / Super finish grinding, typically a D9 – D6 micron grit size is selected.

Wheel shapes are most commonly 6A2 and 11A2 Styles. These wheel core shapes are very rigid by design and are typically used on dedicated PDC / PCBN grinding machines such as Coborn, EWAG, Toyoda and Waida to name a few.
