An Idea was Born

In 1993, OMAX Corporation became the first company to make abrasive waterjet machining more precise, affordable, and easy to use. We are proud that the revolutionary work we have done has helped make abrasive waterjet machining one of the most versatile manufacturing technologies today. Now, two decades later, we are the global leader in advanced abrasive waterjet systems and have made it possible for virtually anyone to go as far as creating high-precision complex 3D parts on our machines.


To provide precise, easy-to-use, cost effective, standardized, reliable, and high quality abrasive-jet machining systems to the manufacturing industry, with strong after-sale services.

One Company, Everything You Need

We are the only fully integrated abrasive waterjet company to design and produce its own pumps, high pressure plumbing, machine controllers, software, tables, and accessories, while providing unparalleled support and service.

Innovative Visionaries
Meet our Founders

When Dr. John Cheung, and Dr. John Olsen founded OMAX Corporation, they already had decades of experience working with abrasive waterjet technology. Upon establishing the company, they developed and combined a new motion control technology with proprietary software to create an accurate, affordable abrasive waterjet machine that was unlike anything else on the market. Today, these two innovators remain highly engaged in product development and work closely with company engineers to continuously introduce new technology for an ever-evolving industry.
