sheet metalguillotineswing-beam

Overview
The KHT 4006 M NC is a hydraulic guillotine shear designed with a swing‑beam (pivot) cutting concept. The cutter beam runs in a pivot bearing anchored in the machine frame, ensuring straight cuts and preventing upper/lower blade jam. The back gauge is positioned precisely via the ESTUN E21 NC controller.

Highlights

• ESTUN E21 NC numerical control for accurate back‑gauge positioning
• Preloaded ball‑screw back gauge
• Pneumatic plate hold‑up system
• Knives suitable for stainless steel
• Adjustable angular stop and long front support arms

Machine frame

• Stress‑relieved welded steel frame in swing‑beam design for low‑torsion cuts
• Cutter beam moves in an arc so blade clearance is restored after each cut
• Design benefits: predictable part release, stable cutting quality, simplified knife clearance adjustment

Material support

• Large work table with roller balls for easy handling and plate alignment
• Rigid adjustable angular stop and four long front support arms (1,000 mm)

Hydraulics

• Reliable, low‑maintenance hydraulic system with service‑friendly layout
• Hydraulically regulated hold‑downs secure the sheet close to the cut line

Back gauge

• Robust back‑gauge system suitable for industrial production environments
• Preloaded ball screws mounted in a protective enclosure; feed speed X‑axis: 2,280 mm/min

Equipment

• ESTUN E21 NC control for single cuts and program runs
• Mobile foot pedal with emergency stop
• Cut‑line indication via shadow graph
• Upper and lower knives configured for stainless steel cutting capability

Safety

• Continuous finger guard with flip‑up section for improved view of the cut line (folds up to 1,000 mm)
• Rear light barrier protecting the back working area
• Safety features compliant with current CE regulations
