Our inspection room


Quality Control

We continuously upgrade our  inspection equipment so we can deliver quality parts to our customers' expectations.  We have our equipment calibrated each year.  Below are a few of our newest purchases.


Fowler Trimos

In 2016, we added the Fowler Trimos Digital Height Gauge to our inspection Dept, it has the capability of measuring tight tolerances down to .0001 with a max height of 24".


Dorsey Comparator

We purchased our new Dorsey Comparitor with edge detection to more accurately inspect parts.  It has proven to be an invaluable addition to our inspection equipment and is used daily.

Graham Tool & Machine remains committed to quality and improvement.
