Knuth 10HP 126” KHT 3006 M NC Hydraulic Swing-Beam Shear 184210

Description

The models from the KHT M NC series are built under a swing-beam design. The cutting bar is guided in a pivot bearing anchored in the machine body making cuts very straight without the risk of upper and lower blades jamming. The robust back gauge precisely positioned via the ESTUN 21 NC controller.

Features

• The hydraulic Swing-Beam Shears with NC-controlled back gauge combines quality, reliability, and easy handling
• ESTUN 21 NC control
• Motorized back gauge
• Pneum. sheet hold-up device
• Cutter for stainless steel
• Adjustable angular stop

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
