Waterjet Cuts Delicate, Complex Patterns

Omax’s MicroMax JetMachining Center is capable of cutting micron-level parts or features from materials including exotic metals, composites, polymer thermoplastics and glass. Suitable for prototype development as well as production runs, the waterjet cutting center offers a table measuring 28" × 28" and X-Y cutting travel of 24" × 24". According to the company, the waterjet’s high-precision linear encoders, vibration isolation and software control systems enable position repeatability of less than 3 microns and positioning accuracy of approximately 15 microns (0.0006").

The waterjet is equipped with a high-precision 7/15 Mini MaxJet51 nozzle with a 0.007" orifice and 0.015" mixing tube combination said to enable quickly and accurately cutting delicate, complex patterns. The nozzle is capable of producing a kerf as small as 0.015" with a jet stream carrying a fine abrasive. The machine also features pressure controls for piercing delicate materials.

The waterjet cutting machine can be equipped with a smaller version of Omax’s Tilt-A-Jet cutting head, which is said achieve virtually zero taper in materials as thick as 3". The cutting head for the MicroMax JetMachining Center is 25 percent smaller and lighter than the standard model and is designed with greater rigidity for less deflection. The head employs 10 degrees of tilt and is fully sealed for use in the abrasive waterjet environment.
