Macro Junior, a reference system tailor made for a modern EDM technology

  • Automatic electrode changing and unmanned production.

  • The patented and compact Macro Junior system is intended mainly for small electrodes.

  • Unlike other Macro systems, in Macro Junior the chuck, not the electrode holder, has positioning tongues.

  • A design which means that the electrode holders can be supplied at a very attractive price.

  • The design with three reference points in the X-, Y- and Z-directions means that, despite any tolerance variations in the holder, the coupling repeats very accurately when it is locked with its screw connection.

Features:

  • Clamping force 5.000N
  • Repeatability <0.002mm
  • High accuracy
  • High stability
  • Max. flushing pressure 15 bar
