What is CNC Machining?
CNC
(Computer Numerical Control) machining is a subtractive manufacturing
process where a computer-controlled machine tool removes material from a
workpiece to create a custom-designed part. Unlike conventional manual
machining, CNC machining relies on programmed instructions (G-code) to
control the movement of cutting tools with high precision, speed, and
repeatability.
Key Advantages of CNC Machining:
✔ High Precision & Accuracy – Tolerances as tight as ±0.001" (0.025mm) or better.
✔ Faster Production – Automated operations reduce human error and increase efficiency.
✔ Complex Geometries – Multi-axis CNC machines can produce intricate shapes that are difficult or impossible with manual methods.
✔ Repeatability – Ideal for mass production of identical parts.
What is CNC Machining Used For?
CNC machining is widely used across industries for:
Prototyping & End-Use Parts – Functional components for aerospace, automotive, medical, and electronics.
Tooling – Molds for plastic injection molding, die casting, and stamping dies.
Secondary Operations – Drilling, tapping, milling, and finishing on pre-machined or cast/forged parts.
Custom Fabrication – One-off or low-volume precision parts.
Types of CNC Machines
While there are many specialized CNC machines, the most common include:
CNC Mills – Versatile 3-axis to 5-axis machines for milling complex shapes.
CNC Lathes – For turning cylindrical parts.
CNC Routers – Used for wood, plastics, and softer metals.
CNC EDM (Electrical Discharge Machining) – For hard metals and intricate details.
CNC Grinders – For high-precision surface finishing.
