Product Overview

Ever wonder how complex metal parts go from a digital design to a physical object in your hand? That’s the magic of CNC machining. It’s the behind-the-scenes process that creates everything from tiny medical device components to massive aerospace parts with incredible accuracy.

What is CNC Machining Anyway?

CNC stands for Computer Numerical Control. In simple terms, it’s a manufacturing process where computers control cutting tools to shape metal (or other materials) with extreme precision.

Think of it like a robotic sculptor that can carve metal into virtually any shape you can imagine—as long as you can design it in 3D software.

Why CNC is the Go-To for Precision Metal Parts

• Crazy Accuracy: We’re talking tolerances within ±0.025mm or even tighter. That’s thinner than a human hair!

• Consistency: The first part and the thousandth part will be identical.

• Material Flexibility: Works with everything from aluminum and stainless steel to titanium and exotic alloys.

• Complexity Master: It can create shapes that are impossible with other methods.

The Metals We Work With Most

Different projects need different materials. Here’s a quick guide:

• Aluminum

• Stainless Steel

• Titanium

• Brass

• Copper

Common Applications (You'd Be Surprised)

• Medical: Surgical instruments, implant components

• Aerospace: Engine parts, landing gear components

• Automotive: Prototype brackets, custom fittings

• Electronics: Heat sinks, enclosures, connectors

• Robotics: Joints, actuators, custom gears

What Makes a Part "Precision" Machined?

Precision isn’t just a marketing term—it’s a measurable standard:

• Tight Tolerances: Typically between ±0.025mm to ±0.125mm

• Surface Finish: Smooth finishes under 0.4μm Ra

• Repeatability: Every part matches the digital design exactly

• Documentation: Inspection reports that verify critical dimensions

Ready to Get Started?

Whether you need one prototype or thousands of production parts, CNC machining delivers precision and reliability that’s hard to beat.

Q: How fast can I receive a CNC prototype?

A: Lead times vary depending on part complexity, material availability, and finishing requirements, but generally:

• Simple prototypes: 1–3 business days

• Complex or multi-part projects: 5–10 business days

Expedited service is often available.

Q: What design files do I need to provide?

A: To get started, you should submit:

• 3D CAD files (preferably in STEP, IGES, or STL format)

• 2D drawings (PDF or DWG) if specific tolerances, threads, or surface finishes are required

Q: Can you handle tight tolerances?

A: Yes. CNC machining is ideal for achieving tight tolerances, typically within:

• ±0.005" (±0.127 mm) standard

• Tighter tolerances available upon request (e.g., ±0.001" or better)

Q: Is CNC prototyping suitable for functional testing?

A: Yes. CNC prototypes are made from real engineering-grade materials, making them ideal for functional testing, fit checks, and mechanical evaluations.

Q: Do you offer low-volume production in addition to prototypes?

A: Yes. Many CNC services provide bridge production or low-volume manufacturing, ideal for quantities from 1 to several hundred units.

Q: Is my design confidential?

A: Yes. Reputable CNC prototype services always sign Non-Disclosure Agreements (NDAs) and treat your files and intellectual property with full confidentiality.
