CNC parts are produced through subtractive manufacturing, where material is removed from a solid block (metal, plastic, or composite) using computer-controlled machines. Key processes include:
Milling – Cutting tools rotate to shape the workpiece (3-axis to 5-axis CNC mills).
Turning – The workpiece rotates while a tool cuts (lathes for cylindrical parts).
Swiss Machining – Ultra-precise turning for small, complex components.
EDM (Electrical Discharge Machining) – For hard metals using electrical sparks.
Key Applications
Aerospace: Turbine blades, landing gear, and structural components.
Automotive: Engine blocks, transmission gears, and EV battery housings.
Medical: Surgical tools, orthopedic implants, and dental prosthetics.
Electronics: Heat sinks, connectors, and microfluidic devices.
