Precision Machining for Functional Prototypes and End-use Parts

Get improved tolerances, fully machined features, and detailed inspections

You know us as the fastest manufacturing supplier of machined parts, but sometimes your project requirements outweigh the need for speed. We machine highly precise parts with multiple finishing and reporting options—just what you need for parts with high-end specifications.

Precision machining makes sense when you need lower quantities with higher part requirements. Lead times still can be as few as 10 days!

Advantages of Precision Machining

Machining complexity often brings with it high-level requirements. To ensure that your parts meet your needs, we include design feedback from applications engineers. You’ll also get:

  • Tolerances as tight as +/-0.002 in. (0.0508mm)
  • Fulfillment of quality requirements (including CoC, FAI, ISO 9001, and AS9100)
  • Fully machined features (no material left behind)

Design Guidelines for Precision Machining

Maximum Dimensions

3-axis Milling 36 in. x 24 in. x 13 in.
5-axis Milling 16 in. x 16 in. x 16 in.
EDM 23.5 in. x 15.5 in. x 12.5 in.
Turning 10 in. x 18 in.
3-axis Milling 914.4mm x 609.6mm x 330.2mm
5-axis Milling 406.4mm x 406.4mm x 406.4mm
EDM 596.9mm x 393.7mm x 317.5mm
Turning 254mm x 457.2mm

Other Design Considerations
  • Maximum part weight: 75 pounds (34.02kg)
  • 3D CAD file preferred; prints are accepted for additional specification
