This is a low-volume production service for CNC turned and milled components in aluminum alloy, brass, copper and stainless steel, bridging the gap between prototypes and mass production. Quantities from tens to a few thousand pieces are typical, with ±0.05 mm standard tolerance. It suits startups and OEMs launching products, running pilot builds or serving niche markets without tooling investment.

- Prototype programs carried into production
- Tens to a few thousand pieces
- Free-machining grades to cut cost
- Typically 10–20 working days for production

## How we make it
Low-volume runs use the same CNC programs proven during prototyping, refined for cycle time once the design is frozen. Fixtures are simplified so setup cost stays reasonable across smaller batches, and bar-fed lathes run turned parts with minimal attention. Multi-part orders are scheduled to share setups where materials match. Each repeat order references the approved program and inspection plan for consistency.

Aluminum alloy is the most economical choice for housings, spacers and brackets, especially when anodized. Brass is efficient for small turned parts with threads, and copper serves conductive parts despite slower machining. Stainless steel adds strength and corrosion resistance at higher cost. Choosing a free-machining grade, such as 303 instead of 304, can reduce cost noticeably on large turned batches.

First-article inspection is approved before the batch, in-process checks run at set intervals, and every critical dimension is inspected before shipment. Production usually takes 10–20 working days depending on quantity and finish. Typical uses include product launches, pilot builds, spare parts programs, specialist equipment, seasonal products and replacement parts for products already in the field.

## FAQ
### At what quantity should I move from CNC machining to casting or molding?
It depends on part size, complexity and target cost. Machining often stays competitive up to a few hundred or a few thousand pieces because there is no tooling. We can quote machining alongside casting or molding with tooling so you can see the break-even point.

### Will low-volume parts match the approved prototypes?
Yes. Production uses the approved drawing, program and inspection plan from the prototype stage. Any changes for efficiency are checked against the drawing, and first articles from the production batch are inspected before the full run proceeds.

### How do I get a quote for low-volume cnc turned aluminum and brass components?
Send a 3D model (STEP or IGES) and a 2D drawing with tolerances, material, finish and quantity through the quote form or by email. An engineer replies within 24 hours on business days with price, lead time and any DFM suggestions.
