A milling machine is a machine tool that uses a milling cutter to process workpieces. When the milling machine is working, the workpiece is installed on the workbench or indexing head and other accessories. The milling cutter rotates as the main motion, supplemented by the feed motion of the workbench or milling head, and the workpiece can obtain the required machining surface. Due to intermittent cutting with multiple cutters, the productivity of milling machines is relatively high. In addition to milling flat surfaces (horizontal and vertical surfaces), gear teeth, grooves (keyways, T-grooves, dovetail grooves, etc.), spline shafts, and spiral surfaces (threads, spiral grooves), milling machines can also process more complex surfaces, with higher efficiency than planers. They are widely used in mechanical manufacturing and repair departments.
A lathe is a machine tool that primarily uses turning tools to perform machining on rotating workpieces. On the lathe, corresponding machining can also be carried out using drill bits, reamers, reamers, dies, taps, and knurling tools. Lathe is mainly used for machining discs, shafts, sleeves, and other workpieces with rotating surfaces. It is a widely used type of machine tool in mechanical manufacturing and repair factories. The rotating processing machinery such as milling machines and drilling machines are all extended from lathes.
Both types of machine tools are programmed to follow the cutting path, which is called CNC mode. Adding the word CNC before its name means automated machining.
