capability. In addition, Omax is modifying its Tilt-A-Jet cutting head to mount it on the MicroMAX. The Tilt-A-Jet will be available as an option, which will minimize the taper of parts up to 40-mm thick.


The machine also has Omax’s advanced pressure controls for piercing delicate materials, minimizing the prob- ability of delamination or cracking inside a blind hole. “One of the problems with conventional waterjet is piercing delicate materials like laminates, com- posites or glass,” said Liu. “When you try to pierce with the waterjet, before it breaks through the material the jet decelerates, stops, and reverses its di- rection at the bottom of the blind hole. “A large stagnating pressure devel- ops inside the blind hole, and piercing- related damage results when the stag- nating pressure exceeds the tensile/ adhesive strength of the materials.” The new waterjet machining center can also precisely cut stainless steel, tita- nium, nitinol, graphite, copper, and more, Liu said. In addition, laboratory testing us- ing the MicroMAX to cut fi ber-reinforced PEEK showed the fi bers are cut cleanly, he said. The MicroMAX’s table is 0.71 ×
