Applications

Where It Works

  • Angular and radial hole patterns on flat sheet that turret punch presses cannot run without repositioning
  • Long sheets over 2 meters requiring punched features across the full length in a single CNC program
  • Parts with mixed straight and angular hole arrays where a rotation punch eliminates secondary operations

Features

Built In

  • Zero backlash Harmonic Drive gear system indexes the punch head to any angle with no mechanical play, so angular hole patterns run without repositioning the sheet
  • Automatic X-axis reposition extends punching capability beyond 2 meters on a single sheet, eliminating the dead zone that limits standard turret punch presses
  • 40 rpm rotational speed keeps cycle times competitive on parts with dense angular feature patterns
