Materials for CNC Milling and Turning

Metal or plastic you pick decides how your part performs under load and how it takes a finish. Sango stocks and machines the materials below on a daily basis.

Surface Finishes for CNC Machined Parts

Post-processing changes how a part looks, how it resists corrosion, and sometimes how big it is. Pick the finish at quoting stage so tolerance is calculated around it.

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

CNC Technical FAQ CAD & Blueprint
Can Sango handle a project that needs milling, turning and finishing all in one order?

Yes. That is the point of running all three under one roof. A shaft that needs a turned diameter, a milled flat and an anodized finish does not need three separate quotes from three separate vendors. You submit one CAD file, get one quote covering every process, and receive one finished part.

How fast can Sango deliver CNC milled parts?
What surface finishes and colors are available for CNC machined parts?
Do you offer material certificates and inspection reports?
What tolerances can Sango hold on CNC milled parts?
What if my finished parts do not meet the approved specifications?
