5-Axis CNC Machining Services in California

C&W Manufacturing provides 5-axis CNC machining for complex, multi-face parts that would otherwise need several setups on a 3-axis mill: impeller-style geometry, angled ports and bosses, deep pockets reached from the side, and housings with features on every face. Five CNC mills, including 5-axis capability and a large-format machine with 50 inches of X travel, run under an AS9100D quality system with in-machine probing and AS9102 first-article inspection. ITAR registered, prototype through production.

Capabilities at a glance

The facts a sourcing engineer needs first. Everything below is repeated in more depth on our services and about pages and documented on the certifications page.

  1. MillingFive CNC mills: 3, 4 and 5-axis, the largest with 50 in of X travel; manual mills for secondary operations
  2. Why 5-axisOne setup instead of three or four: fewer fixtures, no re-datuming error between faces, better true position on features that reference each other, shorter lead time on complex parts

What 5-axis buys you

Fewer setups, better geometry

Every re-fixture adds a datum shift. Machining all faces in one clamping keeps position tolerances between faces tight and removes the stack of setup errors that a 3-axis process accumulates.

Angled features without fixtures

Compound-angle holes, ports and bosses are cut by tilting the part to the tool instead of building a sine-plate fixture for each angle. That is where most of the cost saving on low-volume aerospace parts comes from.

Short tools, better finish

Tilting the head lets a short, rigid tool reach into deep pockets and along walls that a long 3-axis tool would chatter on. Surface finish and tolerance improve together.

Hard alloys, planned sequences

Titanium and Inconel parts are roughed, heat treated where the spec calls for it, and finish-machined in a planned sequence so aged parts come out on size. See our Inconel machining guide.

Documentation primes expect

AS9102 first-article inspection, CMM data, certificates of conformance and full traceability under the AS9100D system, with export-controlled data handled per ITAR and CMMC Level 2.

Frequently asked questions

What is 5-axis CNC machining?

A 5-axis mill moves the cutting tool along the three linear axes (X, Y, Z) and rotates the part or the head about two rotary axes (typically A and C, or B and C). That lets the tool reach five sides of a part in a single setup and approach surfaces at compound angles, which is how complex aerospace housings, manifolds and brackets are machined without stacks of fixtures.

When does a part need 5-axis instead of 3-axis?

When it has features on several faces that must be located to each other tightly, when it has angled holes or surfaces, when deep pockets need short tools, or when the number of 3-axis setups makes the part slow and error-prone. A simple plate with holes from one side does not need it; a housing with ports on four sides does.

How big a part can you machine?

The largest of our five CNC mills has 50 inches of X travel, so long brackets, rails and plates run in one piece. Ask about the full envelope for your specific part; the shape of the part and the fixturing matter as much as the raw travel.

Which materials do you 5-axis machine?

Aluminum (6061, 7075, 7050, 2024), stainless steels including 17-4 PH, 4140 and 4340 alloy steel, titanium, Inconel 625 and 718 and other nickel superalloys, and engineering plastics. Our resource library has a selection guide for each family.

Do you provide first-article inspection?

Yes. AS9102 first article inspection reports with CMM data are standard for aerospace and defense programs, under our AS9100D and ISO 9001:2015 certified quality system.

Can you handle ITAR or CUI drawings?

Yes. C&W is ITAR registered, JCP DD-2345 certified and holds CMMC Level 2 status in SPRS. Controlled technical data is accepted only through a U.S.-hosted secure channel; contact us before sending files.
