What Is CNC Milling?

CNC milling is a subtractive machining process where rotating cutting tools remove material from a fixed workpiece to create precise features — pockets, slots, threads, sculptured surfaces and tight-tolerance bores. It is the backbone process for most custom metal and plastic parts.

Our milling capacity covers the full spectrum: 3-axis for cost-effective prismatic parts, 4-axis for multi-face features in one setup, and full 5-axis simultaneous machining for complex geometries that would otherwise require multiple fixtures and longer lead times.

FAQ

CNC Milling Questions

What is the difference between 3-axis, 4-axis and 5-axis milling?

3-axis milling moves on X, Y and Z — best for prismatic parts. 4-axis adds rotation around one axis for multi-face machining. 5-axis machines complex geometries in a single setup, improving accuracy and reducing lead time for curved or angled features.

What tolerance can CNC milling achieve?

Standard milling tolerance is ±0.05mm. With 5-axis equipment and proper fixturing we hold ±0.01mm on critical features depending on geometry and material.

How much does CNC milling cost?

Cost depends on material, complexity, tolerance, quantity and finish. Upload your drawings for an itemized quote within 24 hours — machining time, material and finishing are shown separately.

Milling vs. turning — which do I need?

Turning is best for round/symmetric parts (shafts, bushings); milling suits prismatic parts with pockets and slots. Many parts combine both — our mill-turn centers handle them in one setup.
