Sharpening of flat and round broaching tools

The BGS product line consists of machines designed for the sharpening of flat and round broaching tools found mainly in the automotive and aerospace industries.  Design and programming of the BGS is based on many years of manufacturing experience and knowledge of the tool industry.  The BGS series signifies not only a machine concept but also a complete technological package consisting of machine and competence in the tool manufacturing arena.

The machines of the BGS series are specifically designed for the sharpening process. The design concept with high dynamics and adapted grinding spindle allow the efficient and economic sharpening of broaching tools. An onboard measuring device probes the tooth root and cutting edge to determine the tooth pitch. 

The machines are available as a standard for tools with circular flutes or through the optional pivoting spindle for circular and helical flutes.

  • Efficient and economic sharpening of broaching tools
  • Quick setup times when switching between circular and flat broaches
  • Easy to program through parameter input
  • Measuring probes to collect raw parts
  • Measuring probes to quickly and easily gather the tools geometry for resharpening

Design Characteristics

  • Ball screw driven table with glass scale
  • Dressing spindle on the work table (as an option)

Machine Concept

  • Moving table configuration with a micro granite base
  • Linear guideway technology

Controls

  • Siemens 840D sl
  • Special software packages for sharpening broaches
