FAQ

Q: What tolerance can CNC Swiss-type brass turning achieve for precision brass components?

A: Capability depends on geometry and batch size; critical features can be controlled tighter than general ISO 2768 machining standards for CNC turned brass parts.

Q: Which brass grades are most suitable for high-volume CNC machining production?

A: C36000 is preferred for high-speed mass production due to machinability, while C46400 is used when corrosion resistance is critical in CNC brass components.

Q: Can CNC Swiss machining handle long, thin, or unstable brass turned parts?

A: Yes, Swiss-type CNC turning is specifically designed for slender geometries using guide bushing support for stable precision machining.

Q: What factors most affect the cost of CNC brass turned parts OEM production?

A: Cost is mainly driven by feature complexity, secondary operations, tolerance tightening, and material grade selection.

Q: What file formats are preferred for CNC brass machining quotation and engineering review?

A: STEP files are optimal for CNC turning evaluation; 2D PDF drawings are used for tolerance and inspection requirement validation.
