CNC turning and milling is the process of holding a material in a spindle, with a cutting tool removing layers from the material. This approach works best for cylindrical items such as rods and tubes, and shafts. The cutting tool cuts in a linear motion while the material undergoes high-speed rotation. This makes it easy to shape, drill, and thread exactly how it is required. Modern turning centers support multi-axis operation, enabling more complex work. It is extensively used in the automotive, aerospace, and mechanical industries.
