Top Quality Precision Machining Services

무료 프로젝트 검토로 시작하기

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 5 days! 

Advantages of Precision Machining

Machining complexity often brings with it high-level requirements, requirements where additional documentation like 2D drawings are necessary. To ensure that your parts meet your needs, we accept 2D drawings and include design feedback from applications engineers. You’ll also get: 

  • Tolerances as tight as +/-0.002 in. (0.0508mm)
  • Tolerances adhere to ISO 2768*
  • Fulfillment of quality requirements (including CoC, FAI, ISO 9001, and AS9100)
  • Fully machined features (no material left behind) 

*For parts being manufactured through our network of manufacturing partners, we guarantee ISO 2768 standards for all CNC machined parts. Metal parts will follow ISO 2768-m (medium) or ISO 2768-f (fine). Plastic parts will follow ISO 2768-m (medium). Tolerances down to +/- 0.0004 in. (0.010 mm) are possible but must be clearly indicated in 2D drawings.
