Product information

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.
