Equipment

Our field of expertise is primarily CNC production turning, supported by secondary milling, honing (or lapping) and grinding operations. Our specialty is hydraulic valve components for aircraft and navy submarine industries. These valve components consist of slides, sleeves, pistons, shafts and ms & an fittings etc., many of which have OD tolerances of ±.0001 and linear groove & shoulder tolerances of .0005, with finishes of 8√ or better.

When requirements for heat treating, case hardening, nitriding, flash chrome or hard chrome plating, NDT inspection, and other processes are required, they are accomplished by customer-approved outside processors.
