What “custom CNC parts” means here

A custom CNC part is any component machined to your drawing rather than pulled from a catalog. There is no minimum order and no standard shape we have to fit — you send a STEP, DWG or PDF and we quote the process, material and inspection needed to make it to spec. That covers one-off prototypes, bridge quantities, and recurring production runs.

Processes for custom parts

CNC milling for housings, brackets, manifolds and contoured features
CNC turning for shafts, bushings, threaded and round parts
5-axis machining for compound angles and sculpted surfaces in one setup
Prototyping in real production material, 3–7 day lead
Low-volume production with locked fixtures for batch consistency

Materials for custom parts

We machine the common engineering materials to drawing: aluminum (6061, 7075), stainless (304, 316, 17-4PH), mild and alloy steel, titanium, brass, copper, and plastics such as POM and PEEK. Certified stock is available, and material certificates ship with the parts on request.

Tolerances and inspection

Standard tolerance ±0.05 mm (ISO 2768-m)
Precision tolerance ±0.01 mm on critical features, measured on a CMM
Surface finish to Ra 0.8 µm on bearing and sliding surfaces
First-article inspection with measured data tied to your drawing

Custom prototype and low-volume parts

Custom work usually starts as a prototype. We machine it in the production material, give DFM feedback before cutting, and qualify a first article. Because the same program and fixture carry into low-volume production, a custom part proven at ten pieces runs consistently at volume — no re-qualifying a new shop.

How to get a custom quote

Two fast paths: upload your drawing on the request-a-quote page for a detailed engineer quote within 24 hours, or use the browser-side instant quote tool for a reference price without uploading files. An NDA is available before any file exchange, and the instant tool parses your drawing in your browser so the file never leaves your device.

FAQ

Frequently Asked Questions

What counts as a custom CNC part?

Any part machined to your drawing rather than a catalog standard — one-off prototypes, small batches, or recurring production in your material and tolerance. There is no minimum order; we quote from your STEP, DWG or PDF.

Can you machine custom parts in any material?

We run the common engineering materials: aluminum, stainless and alloy steel, titanium, brass, copper and engineering plastics such as POM and PEEK. Tell us the grade and we will confirm machinability and any special handling up front.

How do I get a quote for custom CNC parts?

Upload your drawing on the request-a-quote page for a detailed engineer quote within 24 hours, or use the browser-side instant quote tool for a reference price without uploading files. An NDA is available before any file exchange.

Do you hold tight tolerances on custom parts?

Yes. Standard ±0.05 mm per ISO 2768-m, with ±0.01 mm available on critical bores, seats and datums, measured on a CMM and reported against your drawing.

Can custom parts scale from prototype to production?

Yes. The same program and fixture carry from first article into low-volume production, so a custom part proven at ten pieces runs consistently at volume.
