Dearborn, Inc.

Precision. Either it is, or it isn’t. With Dearborn it is. We guarantee it. Marketing language aside, precision is the condition of being exact and accurate. Precision machining is the process of removing material from a workpiece while holding very close tolerance finishes, converting it from one function to another. Precision machining can be accomplished through gundrilling, trepanning, honing, CNC milling and turning, centerless grinding, all services provided by Dearborn. Precision machining makes modern life and commerce possible. From the production of aircraft components to medical implants, surgical tools to military applications, precision machining touches every technology and industry. As an example of what we mean by precision, Dearborn routinely holds gundrilling tolerances to a variation of less than .002” up to a bore length of 32’ long. Holding a tolerance that tight is the equivalent of throwing a dart completely straight and hitting a dead-center bullseye of a dart board… 3 miles away! If that sounds difficult, it’s because it is. Dearborn handles this type of precision and accuracy every day. When you need precision, you need Dearborn.
