Hydraulic shear KHT 4008 M NC

sheet metalguillotineswing-beam

Overview
The KHT 4008 M NC is a swing‑beam hydraulic plate shear designed for precise, repeatable sheet cutting in industrial production. The cutter beam runs in a pivot bearing anchored in the machine frame and the robust back gauge is positioned by the ESTUN E21 NC controller. Ideal for steel and stainless steel applications where repeatability and clearance control are required.

Highlights

• ESTUN E21 NC control for precise back gauge positioning
• Preloaded ball‑screw back gauge
• Pneumatic plate hold‑up for safe handling
• Upper and lower knives suitable for stainless steel
• Adjustable angular stop and shadow cutting line

Machine Frame

• Stress‑relieved welded steel construction in swing‑beam design
• Swinging cutter beam restores knife clearance after each cut for low‑torsion results and extended knife life

Material Support

• Large work table with roller balls for easy material handling
• Rigid, adjustable angular stop and long support arms to secure large plates

Hydraulics

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

Back Gauge

• Robust back gauge system built for demanding production environments
• Preloaded ball screws mounted in protective enclosure for durability

Equipment

• ESTUN E21 NC control: single cut and programmed runs positioning
• Mobile foot pedal with emergency‑stop switch
• Shadow graph for visible cut line
• Standard knives for stainless steel and pneumatic plate lift

Safety

• Continuous finger guard foldable to 1000 mm for improved visibility
• Rear light‑barrier protects the back working area
• Safety features compliant with current CE regulations
