Brake Calliper


  • Brakes are safety components made in very
    large quantities
  • Reliable tools, at the same time with low component
    costs, are the challenge which we face daily
  • High requirements for surface finish and accuracy



  • Tool concepts for aluminium and cast iron
  • Constantly developing cutting materials and geometry
    for maximum cutting performance






On-going development

  • Inserts with guided
  • Micro-adjustability
  • Rough and finish machining of piston bore with just one tool



U-axis-systems for machining centres

  • Finish reaming for piston bore
  • Machining seal groove like on
    a lathe solution with KOMET®

Circular interpolating grooving tool

  • Seal ring and dust groove
  • Modern machining centres allow
    new machining methods
