Short Run CNC Machining | Small Volume, Precision Parts
Need professional-quality parts without committing to massive production runs? Short run CNC machining delivers exactly that — precision components in quantities anywhere from a single prototype to 10,000 pieces. Using computer-controlled technology, we create parts that match or exceed the quality of mass production without the excessive costs of setting up injection molding or other high-volume processes. The precision is remarkable — tolerances as tight as ±0.0001 inches.
Our 5-axis machining centers handle those complex geometries that would make other shops nervous — from intricate aerospace components to delicate medical devices, specialized automotive parts, and miniature electronics. The best part? No minimum order requirements. Whether you need one perfect part for testing or a few hundred for a limited production run, we deliver the same quality without forcing you into quantities you don’t actually need.

What Makes Short Run CNC Different From Mass Production?
Short-run CNC machining is essentially the sweet spot between one-off prototypes and massive production runs. It uses computer-guided cutting tools to create small batches of parts without the huge upfront investments traditional manufacturing demands. The whole process relies on sophisticated G-code programming — digital instructions that guide cutting tools with microscopic precision along multiple axes. This approach perfectly fills that awkward gap between prototype development and full-scale production, for quantities were setting up injection molding would cost more than the parts themselves.
Why Smaller Batches Make Perfect Sense
- Skip those expensive mold costs for anything under 10,000 pieces — often saving thousands in setup fees
- Need design tweaks? Just update the program instead of scrapping expensive molds
- Get the same precise quality on part 50 as you did on part 1 thanks to computer-controlled consistency
- Stop waiting around — get parts in 5–15 days instead of weeks or months for traditional methods
Behind the scenes, our CNC mills and lathes follow detailed instructions created in MasterCAM software, using spinning cutting tools like end mills and drill bits to carve your exact specifications from solid blocks of material. The difference is something you can literally measure with a micrometer.

How does CNC Beat Other Manufacturing for Small Quantities?
Short run machining eliminates tooling costs that make traditional manufacturing expensive for small-batch production. Programming changes cost significantly less than tooling modifications, enabling design iterations without financial penalties. Quick turn capabilities compress production schedules because no tooling fabrication is required.
Cost Comparison Benefits
- No upfront tooling investment versus injection molding setup
- Simple reprogramming for design changes in low volume runs
- Material waste reduction through direct machining operations
- Lower risk through smaller financial commitments for one-off projects
The process maintains consistent quality using computer numerical control precision rather than operator-dependent manual methods. Design flexibility allows engineering changes between production runs without scrapping expensive molds.
Which Industries Benefit Most from Short Run CNC?

A medical device company orders 150 titanium bone screws for clinical trials before FDA approval and full production. An aerospace manufacturer needs 75 custom aluminum brackets for a specialized aircraft modification. Electronics companies often require 300-500 custom heat sinks for testing new processor designs before scaling to higher volumes, comparing costs with 3D printing alternatives.
The preparation stage involves CAD analysis, CAM programming, and workholding setup with automated coordinate establishment. The machining stage executes programmed tool paths with real-time monitoring of cutting parameters and dimensional accuracy using online CNC systems. The finishing stage includes inspection, deburring, surface treatments, and documentation with detailed measurement reports for volume CNC applications.
Short run production suits quantities from 1 to 10,000 pieces where tooling costs exceed material and machining expenses, making CNC more economical than injection molding. Long run production becomes favorable at higher quantities, where amortized tooling costs justify injection or other tooled processes. The crossover point typically occurs between 5,000 to 15,000 pieces, depending on part complexity and tooling requirements for specific manufacturing applications.
