CNC Machining Capabilities and Processes

These operations cover almost every machined part a buyer sends us. Which one you need mostly comes down to whether the geometry is symmetric, cylindrical, planar, or multi-axis, and Sango runs all four without handing your job off between vendors.

CNC TurningLathe turning for cylindrical parts, shafts and fittings, with live tooling for cross holes and threading in one setup.

CNC Milling3 and 4-axis machining for complex geometries, cut from solid stock in aluminum, steel and engineering plastics.

CNC RoutingHigh-speed precision routing for sheet materials, large plates, enclosures, carbon fiber, and composite panels.

5 Axis CNCSimultaneous multi-axis continuous milling for complex aerospace impellers, medical implants, and organic shapes.

China's CNC Machine Shops. Ship Globally

Our CNC facilities in China run high volume manufacturing without the wait most buyers expect from an overseas order. That is why a part landing in a Sango customer's hands in as little as 5 to 7 days after order confirmation is routine, not the exception.

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

From a raw machined look to a fully coated production finish, here are the five finishing options most of our customers choose from.

As MachinedMachined finish straight off the tool, Ra 3.2 or better, no added cost or lead time.

Bead BlastingA uniform matte texture that hides tool marks and evens out surface tone.

Anodizing (Type II and Type III)Corrosion resistant, wear resistant coating available in Type II decorative or Type III hard coat.

Powder Coating and PaintingDurable color coating in custom RAL or Pantone shades, applied evenly across complex geometries.

Plating and PolishingA bright, reflective or corrosion resistant surface for functional or cosmetic parts.

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

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 step, and receive your 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?
