CNC Milling
A subtractive machining process in which rotating multi-flute cutting tools remove material from a stationary or moving workpiece. CNC milling machines operate on 3-axis or multi-axis configurations to produce prismatic and complex 3D geometries.
CNC milling is a subtractive process where rotating multi-flute cutting tools remove material from a stationary workpiece, creating features ranging from simple slots and pockets to intricate 3D geometries and complex curved surfaces. Unlike turning, which rotates the part, milling machines move the cutting tool relative to the workpiece, giving operators tremendous flexibility in part design and the ability to machine multiple features on all sides of a part.
Modern CNC milling machines operate on 3-axis or multi-axis configurations that enable simultaneous tool positioning for complex part geometries like aerospace components, medical devices, and architectural metalwork. The precision and repeatability of CNC milling eliminates the manual skill and variability of manual milling machines, ensuring that every part produced meets engineering tolerances consistently.
Feed rates, spindle speeds, and coolant strategies are carefully optimized for each material and operation to maximize tool life and surface finish while maintaining production efficiency.
