Precision machining is CNC machining taken to a tighter standard. It is the difference between "close enough" and "exactly to the drawing, every time."
What Makes It Precise
- Tight tolerances - often ±0.001 in or better, verified with CMM inspection
- Repeatability - the same dimension, part after part
- Fine surface finish - down to Ra 0.8 um or better
- Process control - in-process checks, not just final inspection
Where It Is Used
Precision machining shows up wherever a failure is expensive: aerospace components, medical devices, semiconductor equipment, and high-performance automotive parts.
