Hydraulic shear KHT 3006 M NC

sheet metalguillotineswing-beam

Overview
The KHT 3006 M NC is a hydraulic guillotine shear built on a swing-beam design. The cutting beam is guided in a pivot bearing anchored in the machine frame, ensuring straight cuts and preventing upper/lower blade jamming. The back gauge is positioned precisely by the ESTUN E21 NC controller for single and programmed runs.

Highlights

• ESTUN E21 NC control for accurate positioning
• Preloaded ball-screw back gauge in protective enclosure
• Pneumatic sheet hold‑up for thin material handling
• Upper and lower knives suitable for stainless steel
• Adjustable angular stop and long front support arms

Machine frame

• Stress-relieved welded steel frame with swing-beam construction
• Swinging cutter beam restores upper/lower knife clearance after each cut
• Benefits: low-torsion cuts, reliable part release, extended knife life, simple kerf adjustment

Material support

• Large work table with roller balls for easy plate movement and precise alignment
• Rigid adjustable angular stop and three front support arms (1,000 mm) for large plates

Hydraulics

• Reliable, low‑maintenance hydraulic system designed for heavy production
• Hydraulically regulated hold‑downs secure the sheet close to the cut line during operation

Back gauge

• Robust back gauge system suited to demanding production environments
• Preloaded ball screws mounted in a protective housing for durability and precision

Equipment

• User-friendly ESTUN E21 NC positions the back gauge precisely for single cuts and program sequences
• Machine operated via mobile foot pedal with emergency stop
• Shadow line indicates exact cut position on the sheet
• Standard upper and lower knives for stainless steel (4 cutting sides)

Safety

• Full-length finger guard with flip-up section (up to 1,000 mm) for improved visibility
• Rear light barrier protects the working area
• Safety concept complies with current CE regulations

Standard equipment

• ESTUN E21S NC control — positioning, retracting during cutting, automatic return, backup/recovery, up to 40 programs / 25 steps, power-off protection
