Standard Waterjet

Easily Cut Virtually Any Material

In standard waterjet cutting, the stream remains perpendicular to the material being cut at all times. The supersonic stream accelerates abrasive particles and erodes the material. It is capable of cutting hard materials such as metals, glass, stone, and composites. Using standard parameters, this cutting head can cut materials with hardness up to and slightly beyond aluminum oxide ceramic (often called alumina, AD 99.9) and over 10 inches thick.

Core Component Options

Flow's Paser 4 Cutting Head

PASER 4 Cutting Head

Paser UCL (Ultra Component Life) technology extends orifice and mixing tube component life to an unmatched level. You get lower cost of operation since fewer parts are consumed and maintenance intervals are greatly reduced.

At the core of Flow’s UCL technology is the unique orifice assembly. The Diamond Precision Orifice is our longest lasting, most durable orifice that performs reliably at 60,000 psi/4,150 bar or 87,000 psi/6,000 bar operating pressure. Additionally, we offer other jewel orifice assemblies, such as ruby and sapphire, which offer good life at a reduced cost.

Unlike other abrasive waterjet cutting heads, the PASER 4 has only two consumable parts – the orifice and the mixing tube. No expensive carbide mixing chamber exists in this high-tech cutting head. Similar to our orifice assemblies, we have a variety of performance grades of mixing tube available. These nano-grained composite carbide mixing tubes act as the rifle barrel as the abrasive is entrained and accelerated into the powerful cutting stream.

UltraPierce Vacuum Assist

UltraPierce Vacuum Assist 

Our exclusive UltraPierce™ Vacuum Assist technology provides reliable piercing of brittle and laminated materials such as marble, stone, glass, and composites.

Fragile materials such as these tend to form craters, cracks, or break during high pressure piercing. UltraPierce is a cutting head option that allows the Paser 4 to pierce these materials easily, saving time and raw material, as well as enhancing the quality of the finished product. UltraPierce's exclusive no clog design pulls abrasive into the cutting head a split second before the waterjet starts so that the waterjet has abrasive particles entrained in the jet stream immediately.

Flow's Dynamic Contour Follower

Dynamic Contour Follower and Collision Sensor

The Dynamic Contour Follower™ (DCF) allows for automatic setting and tracking of the stand-off distance between the mixing tube tip and the material being cut, allowing for more efficient and accurate part cutting.

Three independent legs transmit height variations in cutting material in full 360 degree movement on the XY plane. Variations in the XY plane are communicated to the Z-axis producing immediate adjustments in the stand-off height to maintain the ideal cutting environment. It works with both Standard and Dynamic waterjet cutting heads.

The Dynamic Contour Follower can also be used with an optional collision sensor – designed to detect collisions with obstructions and stop the machine before damage can occur.
