Knuth #KHT-H, CNC Hydraulic Shear

These guided hydraulic plate shears with CNC-controlled back gauge, kerf and cutting angle combine high quality and reliability with a user-friendly design

Machine Frame

• The very rigid and heavy machine frame has been welded to tight tolerances and annealed
• The machine frame has been machined on a state-of-the-art 5-axis milling machine in one single setup to ensure more precise cuts and extended life
• All components subject to tensile loads have been carefully constructed and designed with large radii to permanently eliminate the risk of cracking
• The table features a bottom cutter mount and cutter bar and has been designed for minimal torsion and optimum load distribution
• All components were treated in a modern paint and drying system and feature two coats of paint, each coat with a minimum thickness of 60 micron

Material Support

• The large work table features roller balls and a rigid lateral angular stop for easy handling and safe plate alignment
• Long, sturdy support arms safely hold large plates

Hydraulics

• Polished pistons on both hydraulic cylinders feature superior 2 micron surface grades, ensuring a long seal life
• Cylinder bodies are forged from high-strength SAE 1040 material
• 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 and Control

• Length, thickness, and strength of the plate material can easily be entered by the user into the programmable control unit, which then automatically will select the appropriate positions for kerf, cutting angle and cutting length
• The back gauge system is very robust and perfectly suited for rough production environments
• Linear guides and preloaded ball screws are mounted in a protective enclosure

Equipment

• Electric components made by renowned manufacturers ensure problem-free operation and high availability
• Upper and lower knives suitable for stainless steel
• The machine is operated via a foot pedal with emergency stop switch, and the pedal can be located wherever it is most convenient

Safety

• Safety concept based on the latest CE standards
• The rear-mounted light barrier system protects the work area

• CybTouch 8 G is a powerful control that perfectly complements premium plate shears
• Like all CybTouch products, this control features a user-friendly design allowing users to get started quickly
