One-Off Machined Parts, Made to Your Drawing
Need a single custom part, not a production run? We CNC machine one-off parts for prototypes, broken machine components, test fixtures and custom tools — from a drawing, a 3D model or a physical sample.

One-Off CNC Machining Without the Runaround
Most machine shops are built for repeat production and push single-part requests to the bottom of the queue. Our workflow is set up for one-off machining: engineers quote directly from your file, programs are written for the single piece, and setups are kept simple to control cost.
If a one-off order is very small, a minimum machining charge may apply. We show it upfront on the quote so you can decide quickly.
Common one-off jobs
- Replacement parts for machines no longer supported
- Custom adapters, spacers and mounting plates
- Jigs, fixtures and inspection gauges
- Single prototype parts for design checks
- Modified versions of standard parts
No Drawing? Send a Sample or Photos
For replacement parts we can work from a worn or broken sample. Send photos with key dimensions first; if the part is suitable, our engineers measure the sample and prepare a drawing for your confirmation before machining.

One Part Today, More Tomorrow
Many one-off orders become repeat orders. We keep your program and drawing on file, so re-ordering the same part — or a batch of 10 or 100 — is simple. See our low-volume CNC machining service.

Frequently Asked Questions
Do you really machine just one part?
Yes. Single-piece orders are accepted. A minimum machining charge may apply to very small parts and is shown on the quote.
Can you copy a broken part without a drawing?
In many cases yes. Send photos and dimensions first; if suitable, we measure the sample and create a drawing for your approval before machining.
How is a one-off part priced?
Price is based on material, machining time and setup/programming time. Setup is a larger share of cost for single parts, so simple designs are more economical.
Can I order more of the same part later?
Yes. We keep your drawing and program on file for fast repeat orders.
