Get to Know OMAX

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.

Innovative Visionaries

Meet our Founders

John Cheung
John Olsen - VP of Operations
John Olsen

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.


Decades of Experience and Expertise

We have the largest in-house waterjet systems R&D team in the world and engineering staff with hundreds of years of combined waterjet technology experience. It does not stop here, as our technical support and customer service teams also bring decades of abrasive waterjet know-how to our customers.

Dr. John Cheung


Dr. Cheung's history with waterjets and abrasive waterjets goes back to the beginning of the modern industry. After graduating with a PhD in Mechanics and Materials, Dr. Cheung started working with waterjets in 1973 as a research engineer in the United States Bureau of Mines.

Dr. Cheung led early feasibility studies on abrasivejet cutting and drilling for mining and construction applications, and ten years later was president of Flow Industries (from 1982 to 1987).

In addition to being an accomplished engineer, Dr. Cheung also has extensive business experience, having founded or co-founded:

  • ADMAC, Inc. (merged with Flow Systems to form
  • Flow International in 1987)
  • FlowDril
  • and of course OMAX

Dr. Cheung is experienced in product development and managing start-up technology-based companies through initial public offering (IPO). Financing projects included seed capital, venture capital, R&D Partnerships, corporate bonds, bank loans and IPO. Management experience includes project management, engineering management and general management as well as start-up, acquisition and divestiture of business entities in foreign countries.

Dr. John H. Olsen

VP of Operations

Key individuals pioneer the future of emerging industries. The waterjet and abrasivejet industry counts Dr. John H. Olsen of the OMAX Corporation among its innovative visionaries.

From the beginning of his career, Dr. Olsen was interested in liquids and how they moved. His 1966 doctoral thesis in the field of Fluid Mechanics at MIT was a harbinger of things to come in this nascent industry. In 1970, he established a research and development partnership that brought waterjet technology to a small company called Flow Research.

Today, Flow Research spin-offs account for more than $300 million in revenues.

The technology is commonly used in countless and diverse industries: paper, automotive, aerospace, food, metalworking, oil and gas, utility excavation, concrete scarifying and cleaning, and many more.

Dr. Olsen's initial technology focus was in the design, development and manufacture of the high-pressure pump. His work has included the most successful commercial designs of both the original intensifier pump and the advanced direct drive pump.

Dr. Olsen's success in introducing waterjet technology to the industry led him to see the even greater potential for abrasivejets in the average machine shop. But programming the jet's behavior had to be made simple.

The revolution in personal computing power made Dr. Olsen's vision a reality. He founded the OMAX Corporation in 1993. Since then, OMAX has become the leading developer and manufacturer of easy-to-use machine tools based upon the abrasivejet cutting process.
