CNC milling machines and CNC turning machines are the two most commonly used CNC machine tools at present. Their differences are as follows:
1: Different working principles
The processing principle of lathes is that the workpiece rotates and the tool is fixed. During processing, the blank or workpiece is first fixed on the rotating spindle using a fixture. When the spindle rotates, the turret equipped with the tool controls the tool movement to remove excess material from the blank or workpiece. Since the blank or workpiece rotates, the final shape is a certain form of rotating contour, such as a cylinder, sphere, cone, etc.
The processing principle of milling machines is that the tool rotates and the blank or workpiece is fixed. During processing, the blank or workpiece is fixed on the processing platform using a fixture, and then the spindle rotates the tool, and the tool moves on the direction axis to cut the blank or workpiece, which can form a variety of shapes. Below is a video of a CNC lathe in action：
2: Differences in processing technology
Processing technology of CNC turning
CNC lathes are mainly used for rotationally symmetrical parts processing, and can process outer circles, inner circles, end faces, gears, etc. During the machining process of the lathe, the workpiece is fixed on the spindle and rotates, and the tool cuts according to the pre-set path to achieve the machining of the workpiece.
Processing technology of CNC milling machine
CNC milling machine is mainly used for the machining of complex parts such as planes, curved surfaces, and threads. During the machining process of the milling machine, the workpiece is fixed on the workbench, and the milling cutter moves in different directions and cuts according to the pre-set path to achieve the machining of the workpiece. Below is a video of a CNC milling machine working on an injection mold for an automotive part.：
3: Moving path of tools and workpieces
CNC turning: the workpiece rotates, and the turning tool moves along a straight line or curve.
CNC milling: the milling cutter rotates, and the milling cutter moves along a straight line or curve.
