A lathe machine is a machine that mainly uses a turning tool to turn a rotating workpiece. Generally, the turning tool is fixed at a certain position on the machine tool. The workpiece rotates along the shaft under the grip of the clamp and is cut when approaching the cutting edge. Therefore, it is mainly suitable for machining axes, discs, sleeves and other workpieces with rotating surfaces. , is the most widely used type of machine tool in machinery manufacturing and repair factories. Rotary machining machines such as milling machines and drilling machines are all derived from lathes.
Milling machines refer to machine tools that mainly use milling cutters to machine various surfaces on workpieces. Usually, the rotary motion of the milling cutter is the main movement, and the plane movement of the workpiece and the milling cutter is the feed motion. That is to say, its object is fixed at a certain position of the machine tool, and the milling cutter performs high-speed rotary motion under the grip of the fixture. When contacting the workpiece, it processes the plane and groove on the surface, and can also process various curved surfaces, gears, etc. The milling machine is Machine for milling workpieces with milling cutters Machined planes (horizontal, vertical), grooves (keyways, T-slots, dovetails, etc.), toothed components (gears, spline shafts, sprockets) on the milling machine , Spiral surface (threads, spiral grooves) and various curved surfaces.In addition, it can also be used for the surface of rotary body, internal hole processing and cutting work, etc. Because of multi-knife interrupted cutting, the productivity of the milling machine is high
