CBN & Diamond Precision Wheels
Superabrasive wheels for tool room and production grinding to close tolerance. CBN grinds hardened steel; diamond grinds carbide, ceramics and other non-ferrous hard materials. The two are not interchangeable. SES holds the range as an authorised Tyrolit distributor, covering abrasives CBN (cubic boron nitride) and synthetic diamond; bonds Resin, vitrified, metal, electroplated; shapes 1A1, 11V9, 12V9, 6A2, 14A1 and profiled forms; grit D/B 46 to 400 mesh by finish requirement. Executions include CBN wheels for tool grinding, diamond wheels for carbide grinding, vitrified bond superabrasive wheels, resin bond superabrasive wheels, among others. It is specified most often into tool and cutter grinding of HSS and carbide and cylindrical and internal grinding of hardened shafts. Every part is genuine Tyrolit through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find CBN & Diamond Precision Wheels in the parts of a plant where this particular duty actually occurs. In practice that means tool and cutter grinding of HSS and carbide, cylindrical and internal grinding of hardened shafts, surface grinding of hardened die components, and equally camshaft and crankshaft grinding, profile and thread grinding, carbide insert and saw tip sharpening. What links them is the duty rather than the machine name — cbn: Hardened and high-speed steels. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the Tyrolit range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Grinding hardened steel above about 45 HRC — CBN. Diamond reacts chemically with ferrous material at the grind and wears rapidly. Grinding tungsten carbide or ceramic — Diamond, in resin bond for finishing or metal bond for heavy removal. Form must be held over a long production run — Vitrified bond, which dresses accurately and holds profile far better than resin. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Superabrasive wheels are made to the machine and the part. Send the machine spindle speed, mount, part material and hardness with your enquiry — a wheel ordered on diameter alone will almost always be wrong.
