Common Types of CNC Machining Processes
CNC machining encompasses various operations, including CNC milling, CNC turning, CNC grinding, and CNC drilling, among others, each tailored to different manufacturing needs and requirements.
CNC Milling
CNC milling uses rotating multi-point cutting tools to remove material and create complex shapes. It handles operations like drilling, slotting, and contouring, suitable for prototypes and high-volume production with tight tolerances.
CNC Turning
CNC turning (lathe machining) is ideal for cylindrical parts such as shafts, rods, and bushings. It delivers precise diameters and smooth finishes, with flexible setups from 2-axis to 5-axis turning centers.
CNC Grinding
CNC grinding ensures high precision and superior surface finish. Commonly used for hardened metals and critical components such as bearings, molds, and precision tools, it provides excellent dimensional accuracy.
CNC Drilling
CNC drilling specializes in producing accurate holes of various diameters and depths. It is widely used in automotive, aerospace, and industrial machinery, ensuring repeatability and consistency in large batch production.
EDM
CNC EDM (Electrical Discharge Machining) uses electrical sparks to cut and shape hard metals or intricate geometries that are difficult to machine with traditional methods. It’s particularly valuable for molds, dies, and complex cavities.
CNC Cutting
Advanced CNC-controlled cutting methods such as laser and plasma cutting allow fast processing of sheet metals with clean edges. They are suitable for enclosures, brackets, and structural components requiring efficiency and precision.
