Precision

What determines “precision” in the machining world?

When it comes to “precision machining”, the definition is rather varied. When you Google “precision machining”,  “precision milling”, or “precision milling shops”,you get millions of results per term used.

Are all of the shops displayed truly precision shops? How are they defined? Is there a standard in precision?

Precision, by definition, is the state or quality of being precise, exact.

        a)   The ability of a measurement to be consistently reproduced

        b)   The number of significant digits to which a value has been reliably                        measured

        c)   Intended for accurate or exact  measurement

        d)   Made so as to vary minimally from a set standard

        e)   Of or characterized by accurate action

In recent years, a trend has emerged for differentiating best-in-class manufacturers. It is important not to limit the definition of precision, but expand it to three unique precision types:

        1.     Precision- +/- 10 microns or less on the work piece

        2.     Micro precision- +/- 5 microns or less on the work piece

        3.     Ultra precision- +/- 2.5 microns on the work piece

It should be noted that 1 micron is equivalent to .00004”

At Dynamic Precision Products Inc., we have the capability, machinery and expertise, to consistently manufacture parts to micro precision (+/- 5 microns).

Most of our precision maching clients have tolerances that fall into the precision range or higher, a standard, or the norm in exactness, DPPI clients depend on.
