The technique allows pure water to pass through a nozzle of small diameter, 0.18 - 0.35 mm, at very high pressure, usually 3000 - 3500 bars. The water now traveling about 700-850 m/sec, holds enough kinetic energy to cut through any material under this jet.Water Jet Cutting can be subdivided into two branches:

Pure water cutting Abrasive particles cutting (usually sand

The Pure Water Jet Cutting is particularly suitable for the following materials: Thin materials which are not metal, glass or stone: e.g. rubber, foam plastic, cellular plastic, plywood,

corrugated pasteboard, cardboard, leather, fabrics, foodstuffs, etc

Plywood thickness < 6 mm Hard plastic plates < 10 mm Building boards Shape plates and gasket materials especially those with

intricate holes, openings or tight radii

Due to the High speed (15 m/min) and opportunity to fit several nozzles, the Water Jet Cutters are especially suitable volume cutting work

Pure Water Jet CuttingPure Water Jet Cutting

Abrasive Water Jet CuttingAbrasive Water Jet Cutting In Abrasive Water Jet Cutting, sharp crystals of sand are

introduced into the high speed water jet stream significantly enhancing the cutting capacity and the ability to cut very hard and firm materials.

Abrasive Water Jet Cutting is ideal for cutting jobs that cannot be performed by traditional methods Firm fiber-, sandwich-, encapsulated- or honeycomb

structures Valuable materials due to minimal waste Ground stone, hardwood Detaching a piece of material from the middle of the plate Copper

Abrasive Water Jet CuttingAbrasive Water Jet Cutting

Glass including laminates & anti- bandit Titanium Alloys Stainless steel Aluminium

Abrasive Water Jet Cutting is suitable for complicated sheet metal jobs, as parts can be cut in stack without the need for additional trimming to the finished part e.g.: Gear wheels Components with difficult corners, tips, holes

openings and complex contours

Briefly, Water Jet Cutting is the best method for cutting almost all materials.

COLD Cutting Process - no heat affected zones, no hardening- stress-free cutting
