Product information

Description

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.

Features

Improved cool grindingbehaviour:
The extremely highadhesion strength of VCSA enablesa significant reduction in bond content.Consequently, grinding anddressing forces are also reduced.
Improved economic efficiency:
The excellent grinding performancereduces the costs of thegrinding process. Today, therequired economic efficiency ofCBN is reached more quickly, sothat it is possible to switch fromconventional to CBN in moreapplications.
Highest process stability:
The extremely stable productionperformance of the COLUMBIASA enables high reproducibility.The CBN grinding tools guaranteeconsistent workpiece quality withlong dressing intervals.
Additionally even using emulsionbased coolants:
Extremely goodtool life can be achieved as theVCSA bond has an inbuilt chemicalresistance to the negative influenceof these coolants types.
