01
The drawing looks right, the part does not
A 0.1 mm error in a bore or a chamfer that reads fine on a 2D sheet can stop an assembly line. Nobody sees it until metal meets metal. One machined sample costs far less than a scrapped batch of 500.

Where samples go wrong
Four problems a sample is supposed to catch
A sample is cheap insurance. These are the failures it prevents.
02
Your CAD model hides a tool access problem
Deep pockets, sharp internal corners, threads close to a wall. The model renders fine, but a 6 mm end mill cannot reach the floor without a long-reach holder that chatters. A sample run proves the tool path before you commit.
03
The finish is not what the customer expected
As-machined Ra 1.6–3.2 μm looks different from a bead-blasted or anodized surface. Buyers reject on appearance as often as on size. You need the real part in hand, with the real finish, not a render.
04
You cannot wait six weeks to find out
Tooling lead times and overseas freight push first-article checks past the point where a design change is still cheap. Late samples mean late ECOs, re-fixturing and a second round of validation.
How sampling works here
From drawing to sample part in your hands
One process, two paths: a paid single sample, or a free batch sample before the production run.
Path 1 — Single sample
A paid sample part machined to your drawing
Most projects start with one part. You send a STEP file plus a 2D drawing with tolerances and critical dimensions marked. Our engineering team reviews the geometry, flags thin walls, deep cavities and any feature that needs a special holder, then returns a quotation and a free DFM report within 12 hours. If the model is missing a datum or a thread callout, we ask before cutting metal, not after.
The sample is machined on the same class of machine that will run production, so the process you approve is the process you get. Single samples normally take 5 to 10 days depending on material and finishing, and a sample fee applies. That fee covers programming, fixturing and setup, which is why one-off parts cost more per piece than a 500-part run.

- 2What you get backQuotation, DFM notes, and a machined part with inspection report on request
- 3How longQuotation in 12 hours; sample machining typically 5 to 10 days
Path 2 — Batch sample
Free sample for check before mass production
If you are ordering a production run, we machine a sample from the same stock, same program and same fixtures first, then hold it for your approval. That batch sample is free. It lets your quality team measure the real part, run a fit check on the mating assembly and sign off the surface finish before the rest of the order is cut. Nothing moves to full volume until you say so.
Because the first article comes off the production setup, the dimensions you approve are the dimensions you receive. We record the setup sheet, tool list and inspection results for that first article and keep them with the job. If a dimension drifts later, we have a baseline to compare against instead of an argument. Historical late-delivery probability across our floor sits below 2%, and production can start within 24 hours of an approved sample.

Same machines, same inspection standard. The difference is who pays and what happens next.

What we machine
Sample parts across six process families
Sampling is not limited to a single method. Pick the process that matches the geometry.
01
5-axis CNC machining
Complex contoured parts with undercuts and compound angles. 16 simultaneous 5-axis centers handle geometry that needs multiple setups on a 3-axis machine.
02
3-axis and 4-axis milling
Prismatic parts, plates, housings and brackets. 27 three-axis and 12 four-axis mills cover the bulk of sample requests at lower cost.
03
CNC turning and mill-turn
Shafts, bushings, fittings and parts with turned and milled features. 16 mill-turn centers cut both in one setup.
04
Rapid prototyping
When the check is about form and fit rather than material, prototyping gets a physical part in your hands faster than a full machining cycle.
05
Sheet metal fabrication
Enclosures, chassis and brackets. Bends, holes and hardware inserts verified on a real sample before tooling is committed.
06
Surface finishing
Anodizing, plating, powder coating, bead blasting and laser marking. The sample carries the finish you specified, not a substitute.

FAQs
Sample questions engineers ask
How soon can I get a sample?
Quotation and DFM analysis come back within 12 hours of receiving a usable file. Single sample machining typically takes 5 to 10 days depending on material, geometry and finishing.
If the sample is tied to a production order, we machine it on the production setup and the timeline follows the job schedule. Production can start within 24 hours of an approved sample.
Is the sample free?
A single sample carries a fee. It covers programming, fixturing and setup, which is real labor even for one part.
For batch production we provide a free sample for check before mass production. Same material, same program, same fixtures, and the run does not start until you approve.
What files do you need to quote a sample?
A STEP or IGES 3D model plus a 2D drawing with tolerances, datums and critical dimensions marked. Tell us the material, surface finish and quantity.
If a thread callout or a corner radius is missing, we ask before machining. Send the assembly context too if the part has to fit something.
What tolerance can the sample hold?
We hold ±0.005 mm (±0.0002 in) on critical features. Standard machined surfaces come out around Ra 0.8–1.6 μm, and fine finishes reach Ra 0.2–0.8 μm when specified.
Tolerance is only meaningful against a datum. Mark which dimensions are critical and which are reference, so we can spend machine time where it matters.
Can the sample carry the final finish?
Yes. Anodizing, plating, powder coating, black oxide, bead blasting, brushing, polishing and laser marking are available on sample parts.
Anodized and plated samples sometimes measure differently than bare metal because the coating adds thickness. If a coated dimension is critical, say so and we will account for it.
What materials can you machine for a sample?
Aluminum 6061, 7075 and 2024 among others; stainless 303, 304, 316L and 17-4PH; steels including 1018, 1045 and 4140; copper and brass; titanium TC4 and Inconel; plastics such as POM, PEEK, PC and ABS.
Carbon fiber composites are machinable but need special tooling and a feeds-and-speeds trial on each new geometry. Expect that trial to add time to the first sample.
Will you sign an NDA before I send files?
Yes. A non-disclosure agreement is available on request, and uploads are handled as confidential.
If your drawing carries export-control or ITAR restrictions, tell us up front so we can confirm whether we are able to take the job before you transfer anything.
What if the sample does not match the drawing?
Send the measurement report or the marked-up drawing. We compare it against the setup sheet and first-article records kept with the job.
If the deviation is ours, we rework or remake the sample. If the drawing itself was ambiguous, we revise the interpretation before the production run so the same question does not come back at volume.
