What is CNC Machining? A 1-Minute Guide to Precision Manufacturing
CNC machining creates custom metal/plastic parts with unmatched accuracy. In Prime’s 30-year experience, this process delivers ±0.005mm tolerances – essential for aerospace, automotive, and medical industries.
CNC (Computer Numerical Control) machining uses programmed software to automate cutting tools, transforming raw blocks into complex parts with repeatable precision (±0.005–0.1mm). Prime operates 48 advanced CNC mills/lathes producing 500+ daily components for global clients.
Here’s exactly how it works:
The CNC Process in 4 Steps
1️⃣ 3D Model Upload
- Engineers convert CAD designs into machine-readable G-code
2️⃣ Machine Setup
- Operators load material (aluminum, steel, plastic) and install tools
3️⃣ Precision Cutting
- Rotating end mills/drills remove material at 5,000–30,000 RPM
4️⃣ Quality Inspection
- CMMs and laser scanners verify dimensions within 0.01mm accuracy
