  • The hydraulic Swing-Beam Shears with NC-controlled back gauge combines quality, reliability and easy handling

Machine Frame

  • The machine frame is made of a stress-relieved steel weldment and features a swing-beam design
  • With this design, the cutter beam travels in a swinging movement so that the distance between upper and lower knife will be restored automatically after each cut
  • The advantages of this design are low-torsion cuts, a more reliable release of cut parts, extended knife life, and easy kerf adjustments

Material Support

  • The large work table features roller balls and a rigid adjustable angular stop for easy handling and safe plate alignment
  • Long, sturdy support arms safely hold large plates

Hydraulics

  • The entire hydraulic system is reliable, low-maintenance and easy to service
  • During the cut, hydraulically regulated hold-downs ensure steady fixation of the sheet metal plate close to the cut-line

Back Gauge

  • The back gauge system is very robust and perfectly suited for rough production environments
  • Preloaded ball screws are mounted in a protective enclosure

Equipment

  • The user-friendly ESTUN 21 NC control positions the back gauge precisely both in single cuts and within program runs
  • The machine is operated via a mobile foot pedal with emergency stop switch
  • The exact cut line is visible on the metal sheet as a shadow graph
  • Upper and lower knife suitable for stainless steel

Safety

  • The continuous finger guard can be folded down to 39.4" for a better view on the cut line
  • Safety concept based on the latest CE standards
  • The rear-mounted light barrier system protects the work area
