Cutting Length 126 in (10.5 ft)
Shear Angle 1.5°
Stroke Rate 40 strokes/min
Back Gauge Travel 29.5 in
Front Support Depth 39.4 in
Machine Height (Throat / Table Height) 35.4 in
Motor Power 20 HP (approx.)

Key Features

  • High-speed pneumatic clutch system for rapid cycling
  • 40 strokes/min for production efficiency
  • Rigid welded steel frame with stress-relief treatment
  • Three-point roller guide system for precision cutting
  • Four-edge cutting blades (Cr12MoV) for extended life
  • Straight lower blade design reduces sheet deformation
  • Manual blade clearance adjustment for different materials
  • Dual guide rail + ball screw back gauge system
  • Polyurethane hold-down pads to reduce noise and protect material
  • E21S NC control system for back gauge positioning

Performance & Design Highlights
