Pure Water Cutting

This Cutting method is primarily used for cutting soft materials such as rubber, foam, gasket, leather, textiles, foodstufs and many other similar materials. Normal tap water is pressurized at ultra-high pressure levels, and forced through a small precious stone orifice to form an intense cutting stream, the jet stream moves at a velocity of up to 2.5 times the speed of sound, creating the ability to cut at very high feed rates. The rates very according to the material being cut.

Abrasive Cutting

For your hard materials that cannot be machined with water only the water nozzle nut is replaced with the AUTOLINE TM I abrasive cutting head the high velocity waterjet creates a vacuum which pulls the abrasive into a mixing chamber, producing a coherent, exteremely energic abrasive jet stream. This process is ideal for cutting intrecate patterns in sheet metals, composites, decorative stone, synthetic ceramics, glass etc.
