How does CNC Milling work?
CNC milling is a precise manufacturing process. It involves removing material from a workpiece using rotating cutting tools. The process starts with a digital design, usually made using CAD software. Then, this design is converted into a CNC program that controls the movements of the milling machine.
The workpiece is securely fastened to the machine’s table, and the cutting tool, mounted on a spindle, rotates at high speeds. The machine follows the programmed path, making precise cuts to shape the material into the desired form. With high accuracy, CNC milling can create complex shapes and features, like slots, holes, and contours.
Three-axis milling moves the tool along the X, Y, and Z axes. Four-axis milling adds rotation around one axis, while five-axis milling allows rotation around two axes, allowing more intricate designs. This versatility makes CNC milling essential in several industries, from aerospace to medical devices.
