Broach Sharpening Machines by Karl Klink

The geometrical accuracy and cutting quality of broaching tools have a significant bearing on process capability and economy.

Broach sharpening machines are used to keep these factors at a constantly high level throughout the entire service life of a broaching tool.

KARL KLINK developed a kit system for all types of broaching tools for broach sharpening machines:

  • round broaching tools with annular or helical tooth spaces
  • flat broaching tools
  • helical broaching tools with annular or helical tooth spaces

From this kit, it is possible to select the optimum sharpening machine for each individual requirement, up to a broaching tool length of 3,000 mm (special dimensions by request).

Up to 6 axes allow fully automatic sharpening with the following operations:

  • Tooth space and face grinding on rotating broaching tools with annular or helical tooth spaces
  • Tooth space and face grinding on flat broaching tools
  • Flank grinding on flat broaching tools
  • Tooth space and face grinding on helical broaching tools with annular and helical tooth spaces
  • Dressing of ceramic-bonded or plastic-bonded CBN grinding wheels with diamond rollers

The machine concept has proved to be optimally successful in operational use throughout the world:

  • Very high scanning speed of 1,000 mm/min
  • Very user-friendly and easy-to-understand user interface
  • Absolutely no prior knowledge of CNC technology required to work with the machine
  • 3 electronic hand wheels allow working like with a manual machine
