Knuth Water-jet Cutting System Hydro-Jet 2010

Versatile water-jet cutting system for complex cutting tasks

For Abrasive & Pure-Water Cutting

state-of-the-art GPlus Cut control
superior cutting quality and high efficiency
automatic vertical scanner with integrated collision guard
bridge with drives on both sides
high-pressure system up to 3800 bar
abrasive system with large abrasives container (1000 kg) and controlled metering

bilaterally driven and guided gantry
DC servo motors with zero-backlash gears and precise linear guides on all three axes
water tank and guide machine are set up as stand-alone units
fine tuned drive system with helical gears on X and Y axis ensures high precision and reliability
guideways and drive elements are reliably protected from spray water and contamination
extra rigid stainless steel tank with high load bearing capacity
additional catch grid catches small parts
CNC controlled water pressure
CNC-controlled abrasive material supply - the abrasive sand is precisely metered and fed without pressure
future-oriented PC control with graphic user interface and easy to use programming functions

ECOTRON 40.37 High-Pressure Pump – the Standard Pump for Hydro-Jet Cutters

maximum power and reliability for pure-water and abrasive cutting operations
maximum operator safety and low maintenance
hydraulic drive with axial-piston pump
Oil/water heat-exchanger for oil cooling system
pressure booster, complete with high-pressure tubing
Pulsation damper with pressure accumulator
relief valve integrated in the high-pressure circuit

The Hydro-Jet High-Pressure System with pressure transmitter is based on a high-pressure pump with hydraulic drive, pressure transmitter, pulsation damper, pre-filter unit, and pressure relief valve - all mounted on a common base frame.
The quick-relief valve maintains atmospheric pressure in the pipe system upon completion of the cutting process. Sound proofing enclosure is available to dampen the noise level and to protect the high pressure system.
A proportional valve to automatically control the water pressure via CNC control is included.

GPlus 450 Cut

The GPlus 450Cut features a customized user interface that was specifically designed to meet the special requirements for 2-D cutting

Easy, user-oriented operation allows quick creation of programs
Geometry imports from DXF and DIN/ISO program files
Faulty geometries can be repaired and edited with the integrated DXF Analyzer
50 standard macros simplify the creation of a wide variety of geometries
instant display of all starting cut changes in the drawing with simulation option
optimum material utilization via grid nesting function with critical features like turning, mirroring, and manual sorting
automatic cutter head distance calculation for systems with more than one cutter head

material database with plate management function - for the management of all customer-specific data on machined materials, including cutting technology data, and dimensions
optimum contour approach made possible by a multitude of definable starting cut conditions differentiating between circular and non-circular inside and outside contours
zoom feature - enlarges the part view and all starting cuts
User-friendly HMI allow modification of any cutting parameters during cutting, plus easy operation including all required service messages
Cutting and marking in one program
Option: contour nesting for nesting several part types on one plate - ensures optimum plate utilization and time savings
After interruption of a work process, machining may be resumed at the last position
