Precision CNC Machining FAQ
What is precision CNC machining?
Precision CNC machining is used for tight-tolerance OEM components that require controlled accuracy, GD&T review, repeatability and inspection validation.
What tolerances can you achieve?
Standard precision ranges are often reviewed around ±0.05 mm to ±0.10 mm, while high precision features can be reviewed down to ±0.01 mm when design, material, geometry and inspection method allow.
Do you support GD&T drawings?
Yes. Datum control, position, flatness, parallelism, perpendicularity and other GD&T requirements can be reviewed before quotation.
Can you provide CMM reports?
CMM report, FAI, dimensional report, material certificate and CoC can be reviewed based on drawing and project requirements.
What materials can you machine?
FSD reviews aluminum, stainless steel, titanium, brass, copper and engineering plastics such as POM, Nylon, PEEK, PC and ABS.
Do you support prototypes and production?
Prototype, small-batch and repeat production projects can be reviewed according to drawings, quantity and inspection needs.
