What are Turning, Milling & Drilling?

Turning, milling, and drilling are fundamental CNC machining processes that involve subtractive techniques to cut and shape materials with high precision. Turning (lathe machining) rotates the workpiece against a cutting tool to produce cylindrical parts. Milling uses a rotating multi-point cutter to remove material, enabling complex shapes, slots, and surfaces. Drilling employs a rotating drill bit to create accurate holes.

These processes form the core of modern machining, offering excellent dimensional accuracy, repeatability, and fine surface finishes. Together, they enable the creation of intricate parts and prototypes used in various industries, from engine components to custom machinery parts.
