At Precision Metal Machining, Inc., we provide complex, precision machined components and assemblies used by customers in the medical, aerospace, and other advanced manufacturing industries. Utilizing a fleet of CNC milling and turning centers, an efficiently laid out manufacturing facility, and the dedication of a knowledgeable workforce, we are able to provide the quality and service our customers have come to expect from PMMI. Commonly used materials include Custom 455 and 465 stainless steel alloys, exotic materials such as tantalum or Hastelloy, and autoclavable engineered plastics including Celcon and Radel.

CNC milling centers are equipped with up to 4-axis machining ability for the efficient profiling of complex geometries. The size capacity for CNC milling is 40" in length, 22" in width, and 18" in height. We have over 20 milling and turning center which allow us to competitively manufacture a wide range of component types, sizes and volumes.

Typical machining tolerances are on the order of ±0.005" with close work tolerances of ±0.0002" routinely held in precision applications. Specific tolerances can be discussed with the customer, given the part material, size, and geometry. Additional services including polishing, heat treating, and engraving are available and complex assemblies can be completed on-site. For more information about our CNC machining capabilities, see the table below, or contact us directly.
