We bridge the gap between design and delivery by integrating advanced multi-axis machining with comprehensive surface finishing and expert DFM support. Partner with us to achieve flawless part execution, predictable lead times, and reliable batch consistency across all low- and high-volume production runs.
What Are CNC Machined Parts?
CNC machined parts are precision components carved from solid blocks of metal or plastic using Computer Numerical Control (CNC). Unlike manual methods, this automated process uses software-driven cutting tools to remove material with surgical accuracy, transforming raw blanks into complex geometries with repeatable, micron-level tolerances.

Our CNC Machining Parts Capabilities
We leverage state-of-the-art 3-, 4-, and 5-axis CNC machining centers, Swiss-type turning, and precision EDM to master complex geometries that others can't. Our integrated technology allows for the fabrication of intricate features—such as deep cavities, thin walls (down to 0.5mm), and complex aerospace contours—with standard tolerances of ±0.05mm and high-precision capabilities reaching ±0.01mm. From micro-medical components to large industrial manifolds, we ensure micron-level accuracy across all metal and plastic substrates.
Supported by an extensive fleet of 600+ CNC machines and a dedicated workforce of 500+ skilled operators, XTPROTO offers unparalleled manufacturing elasticity. We seamlessly bridge the gap between rapid functional prototyping (1-10 units) and high-volume mass production (100,000+ units). Our 24/7 facility operations ensure reliable 3-7 day lead times, providing the capacity to scale your project from R&D to full-market launch without switching suppliers.
Every project at XTPROTO undergoes a rigorous Design-for-Manufacturing (DFM) review by our team of 120+ seasoned engineers. We don't just cut metal; we partner with you to optimize part geometries, refine material selection (from Aluminum to PEEK), and streamline production strategies. This proactive approach identifies potential bottlenecks early, reducing manufacturing costs by up to 20-30% while ensuring 100% adherence to your functional and dimensional specifications.
High-Precision Multi-Axis Machining (3, 4, & 5-Axis)
XTPROTO delivers specialized CNC machining part services engineered for complex geometries and tight-tolerance components. Utilizing a combination of 5-axis machining centers, Swiss turning, and EDM, we successfully navigate challenges like 0.5 mm thin walls, deep cavities, and micro-fine threading.Supporting both rapid prototyping and full-scale manufacturing, we maintain absolute dimensional fidelity—holding tolerances as tight as ±0.01 for the medical and aerospace sectors. Partner with us for reliable, repeatable, and cost-efficient production of your most demanding designs.

Precision CNC & DFM Support
Complex CAD designs often face production bottlenecks—such as unmachinable geometries, thin walls, or overly tight tolerances—that lead to costly delays and high scrap rates. XTPROTO bridges this gap by acting as an extension of your R&D team.
We provide comprehensive Design for Manufacturability (DFM) analysis for every component before machining begins. Our engineers optimize part geometries, suggest ideal material selections (ranging from aerospace-grade aluminum to high-performance polymers), and refine tolerances for optimal scalability. This proactive approach eliminates manufacturing risks, slashes rework costs, and ensures a seamless transition from rapid prototyping to full-scale production.
