Описание: Machine tools are power-driven machines used to cut, shape, or form metal and other materials into precise parts needed in manufacturing.�� They are the backbone of modern production, enabling accurate, repeatable machining operations like turning, milling, drilling, and grinding.��Basic definitionA machine tool is a stationary, power-driven device that removes material (or sometimes forms it) to give a workpiece an exact shape, size, and surface finish.��These machines use cutting tools, workholding devices (like chucks and vises), and controlled motions along one or more axes to achieve precise dimensions and tolerances.��Main typesTurning machines (lathes, CNC turning centers) rotate the workpiece while a tool removes material to create cylindrical parts and threads.��Milling machines move a rotating cutter against a stationary or moving workpiece to produce flats, slots, pockets, and complex 3D shapes.��Drilling machines create and enlarge holes using rotating drills, reamers, and boring tools.��Grinding machines use abrasive wheels to achieve high-accuracy dimensions and fine surface finishes on hardened materials.��Presses and punch/forging machines shape metal by applying high force, often without chip removal (cold or hot forming).�Conventional vs CNCConventional machine tools are manually operated, with the operator controlling feeds, speeds, and movements by handwheels and levers.��CNC machine tools use computer numerical control to move axes, change tools, and execute complex machining programs with high repeatability and automation.�Common machine tool examplesLathe, milling machine, drill press, grinding machine, shaper, planer, power saw, and various gear-cutting and broaching machines.���Modern multitasking machines combine turning, milling, drilling, and sometimes grinding in a single CNC platform for higher productivity.��If you share what level you want (basic theory vs. detailed classification, or CNC-focused), the explanation can be tailored more to your machining background.
