COLUMBIA grinding wheels from TYROLIT bridge the technological gap between grinding tools made of fused aluminium oxide and superabrasives. For internal cylindrical grinding applications, in particular, these products of specially bonded sintered aluminium oxide develop their full potential and make possible previously unparalleled levels of performance.

With COLUMBIA SA, TYROLIT has created an innovativeproduct line for internal cylindrical and profile grinding withCBN. The VCSA bond, which was specially developedfor this purpose, further enhances the unique propertiesof CBN. The smaller wheel dimensions utilised withininternal cylindrical grinding are particularly suitable for theeconomical use of CBN grinding wheels.
