OMAX is the only fully integrated waterjet company that designs and produces its own pump, high-pressure plumbing, machine controller, software, and tables. OMAX machines are sold through a well-established and growing network of distributors. In addition, its service technicians are available for expert installation, training, maintenance, and repair assistance.

OMAX's founders, Dr. John Cheung and Dr. John Olsen, developed and combined new motion control technology and proprietary software to engineer an abrasive waterjet that meets the needs of manufacturers. OMAX developed a patented easy-to-use "Compute First-Move Later"​ conversational programming system built into the controls of its waterjets.

As one of the world's top abrasive waterjet manufacturers, OMAX Corp. has joined forces with Hypertherm, a global 100% employee-owned industrial cutting solutions leader. As a wholly-owned subsidiary of Hypertherm, OMAX provides cutting-edge integrated abrasive waterjet solutions and world-class aftermarket service with the added resources of a global company.
