Metric Machining was established in 1973 by Richard and Joan Parker in Monrovia California.

We started out in a 5,000 square foot building and dedicated our efforts to providing our customers with quality parts, on-time delivery and competitive prices. Our reputation today reflects this original commitment.

Use of up to date technology and more than 1,000 years of combined experience supports our continuous growth and ability to compete in today’s global market place. We have since then expanded our workspace into a 36,000 square foot building and have added more equipment and more capabilities along the way.


The machines that we use now are quite a bit different than what we started with in 1973.

We still have many of the same machines we started out with and while the equipment has changed our stubborn commitment to quality has not.

In 1986 Metric Machining acquired Western Air Products and Master Machine Products
and in 1990 GOE Engineering was added to our family.

Newer equipment

Metric Machining is now consolidated at our current building in Riverside California.

We are committed to maintaining a level of service and performance that exceeds our customer expectations
and provides the greatest value at the lowest total cost.

We look forward to becoming your long-term provider of precision machined parts.
