Advantages of Precision CNC Machining
Parts with complex machining requirements typically necessitate supplementary documentation such as 2D drawings or 3D models. To ensure that your parts meet your specifications, we accept 2D drawings and include design feedback from our application engineers. You will also receive:
- Tolerances as tight as ±0.002 inches (0.0500 mm)
- Tolerances in compliance with ISO 2768
- Quality assurance according to ISO 9001
*We guarantee that all CNC machined parts comply with ISO 2768 standards. For parts with special tolerance requirements, we can achieve tolerances as tight as ±0.0004 inches (0.010 mm), provided they are clearly specified in the 2D drawings.
