CNC Milling Explained

What Is CNC Milling?

CNC milling is a way to cut metal and plastic into exact shapes. A computer controls spinning tools that remove material from a solid block. This makes your part match your design file perfectly. Columbia teams use our CNC milling for brackets, enclosures, housings, and custom fixtures.

Our Capabilities

CNC Milling Capabilities for Columbia Teams

Columbia is known for University of Missouri research campus driving biomedical device and agricultural sensor prototyping. We handle the precision machining these industries demand.

3-Axis Milling

Flat surfaces, pockets, slots, and drilled holes. Works great for brackets, mounting plates, enclosures, and any part with features on one side.

Most common

4-Axis Milling

Parts that need cuts on multiple sides without removing them from the machine. Faster delivery and lower cost for angled or wrapped features.

Multi-side access

5-Axis Milling

Complex curves, undercuts, and sculpted surfaces. Our 5-axis machines cut from almost any angle. Fewer setups, tighter tolerances.

±0.0005" capable

Large Format Milling

Parts up to 24" x 18" x 12". Oversized brackets, plates, and housings with the same precision as smaller parts.

Up to 24" travel

Micro Milling

Fine features down to 0.005" with tight tolerances. Perfect for small medical devices, electronics, and intricate mechanical parts.

0.005" features

High-Volume Production

From 1 prototype to 5,000+ production parts. Optimized toolpaths and fixturing keep quality consistent across every piece.
