Precision Equipment in Portland specializes in Hard Chrome Plating, cylinder repair and manufacturing.
New CNC Turning Center w/ Live Tooling means faster turn-around and lower cost.


We're committed to stay at the forefront in hi-tech precision machining.


Our new Mori Seiki lathe with built-in motor turret will provide TURNING / BORING / MILLING / DRILLING AND TAPPING all in one set-up. With the 12-station turret we can machine a wide range of components requiring many features and processes at once.


This translates to greater savings, more accurate machining and faster turn around for you.

Industrial Hard Chrome Plating

Precision has chrome plating tanks in continuous operation. All of which utilize the HEEF© 25 plating process which provides a harder, smoother, brighter and more durable chrome surface than conventional chromic baths. Because the HEEF© process can be operated at higher current densities, we can plate at rates twice those of conventional baths. This capability enables us to provide you with a much faster service while still maintaining the highest quality. Hard Chrome Plating to Quality Control Standard QQC-320B or AMS-2460 performed upon request.
