CNC Machined Prototypes
CNC machined prototypes are precision-engineered sample parts produced using computer numerical control (CNC) milling or turning processes, enabling rapid and accurate validation of designs before full-scale production.
Ideal for product development across industries like automotive, aerospace, medical, and consumer electronics, these prototypes are crafted from metals, plastics, or composites to meet exact specifications and functional testing requirements. CNC machining ensures tight tolerances, superior surface finishes, and the ability to replicate complex geometries, making it a cost-effective solution for functional prototypes, fit checks, and performance evaluations. This method accelerates innovation while reducing risks in manufacturing.
Advanced Machining Equipment

FAQ Of Custom CNC Parts
Visit our FAQ center for more questions.
What level of precision can CNC machining achieve? What are the tolerance ranges?
The precision of CNC machining depends on equipment grade and processes. Standard accuracy ranges from ±0.025–0.125mm, while high-precision machining (e.g., Swiss lathes or 5-axis machines) can achieve micron-level tolerances of ±0.002–0.005mm. Key factors include:
-
Material properties (e.g., aluminum is easier to machine to high precision than stainless steel)
-
Tool compensation and temperature control
-
Post-processing (e.g., grinding, polishing).
How is machining quality ensured for complex features (e.g., deep holes, thin walls)?
For challenging geometries, we implement the following solutions:
-
Deep holes: Gun drilling/peck drilling with high-pressure coolant (depth-to-diameter ratio up to 20:1).
-
Thin walls (<0.5mm): Reduced cutting forces + high-speed milling with dynamic strategies.
-
Surface integrity: Stress relief via vibratory or electropolishing.
Can I know your MOQ when I order CNC Machining Parts from you?
For sure. Actually we have no MOQ request in order to support customers, even you just order one parts. This is advantage for you if you have new idea to market fast without being tied to a specific quantity.
