Water-jet cutting with a wide range of applications:

• Mechanical Engineering: Gears, cast-iron parts, steel assemblies, stainless steel, copper, aluminum, titanium, and other metals
• Aerospace Industry: titanium/aluminum/NiCrCo-based alloys and composite materials for use in aircraft components and aircraft engines
• Residential and Industrial Construction: mosaics, slabs, tiles, stone aggregate, concrete, plaster boards, insulation materials, mineral fibres
• Glass Industry: composite glass, safety glass, and Plexiglas
• Wood Processing Industry: laminated wood boards, veneers, hardwood
• Automotive and Automotive Supplier Industry: composite material trims, dashboards, plastic linings, tires, collars, rearview mirrors, seals
• Electric Industry: mica, cellulose, composite resins, printed circuit-boards
• Food Industry: baked goods, fruit, and frozen food

Benefits

• The cold-cutting process ensures distortion-free cutting of any materials, without thermal stress at the cut edges and without alteration of the material structure.
• Allows cutting of any contours, and the cut can be restarted at any contour.
• There is never any direct contact pressure applied on the part. Despite the high kinetic energy, there are no material deformations, and a high cut precision without fraying or burrs is always guaranteed. The part surface is never disturbed.
• Problem materials like plastic coated sheet metal, aluminum, copper, and stainless steel can be cut hassle-free and with utmost precision.
• The very small kerf width allows optimum material utilization and seamless nesting. Raw material resources are preserved and material costs are reduced.
• This clean cutting process is especially environment-friendly, since it generates no cutting or grinding dust, no chips, and no toxic fumes.

High Pressure Pump Ecotron 40.37

• 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.
