CNC milling can process the shape of complex rotary body. Milling is to fix the blank, and use a high-speed rotating cutter to cut the blank and cut out the desired shape and features. Traditional milling is mostly used for simple contour features such as milling contours and grooves. CNC milling machines can process complex shapes and features. The milling and boring processing center can carry out three-axis or multi-axis milling and boring processing, used for processing, molds, inspection tools, tires, thin-walled complex curved surfaces, artificial prostheses, blades and so on. When selecting the content of CNC milling, the advantages and key roles of CNC milling machines should be fully utilized. A common metal cold working method is different from turning in that in CNC milling, the tool rotates at high speed under the drive of the spindle, and the workpiece is relatively stationary.
The difference between turning and CNC milling:
Turning is used to process the parts of the rotary body. The parts are clamped on the machine tool spindle through the three-clamp chuck and rotated at high speed. Then, the turning tool is used to follow the generatrix of the rotary body to cut out the product appearance. Lathes can also process inner holes, threads, bites, etc. The latter two are processed at low speed.
