A high-precision, high-efficiency automated machine tool. Equipped with multi-station turret or power turret, CNC lathe, turning center. The machine tool has a wide range of processing performance. It can process straight-line cylinders, slanted cylinders, arcs, and various complex workpieces such as threads, grooves, and worms. It has various compensation functions for linear interpolation and arc interpolation. It has played a good economic effect in mass production. Numerical control (English name: NumerControl abbreviation: NC technology refers to a technology that uses digital instructions composed of numbers, words and symbols to realize the motion control of one or more mechanical equipment.
Numerical control generally adopts a general-purpose or special-purpose computer to realize digital sequence control, so numerical control is also called computer numerical control (ComputerNumerControl referred to as CNC abroad, generally referred to as CNC). CNC is rarely used. The concept of NC is often used to control CNC machine tools. It usually controls the position, angle, Mechanical quantities such as speed and switching quantities related to the flow of mechanical energy. The occurrence of numerical control depends on the presentation of data carriers and data operations in binary form.
In 1908, a perforated metal foil interchangeable data carrier came out; at the end of the 19th century, a control system that used paper as a data carrier and had auxiliary functions was invented; in 1938, Shannon conducted fast data calculation and transmission at the Massachusetts Institute of Technology in the United States. Laid the foundation of modern computers, including computer digital control systems.
CNC technology was developed in close combination with machine tool control in 1952. The first CNC machine tool came out, which became an epoch-making event in the history of the world’s machinery industry and promoted the development of automation. At present, the numerical control technology is also called computer numerical control technology (CNCComputerNumerControl). It currently uses a computer to realize digital sequential control technology. This technology uses the computer to execute the sequential logic control function of the device’s movement trajectory and peripheral operations in accordance with the control sequence stored in advance.
Because the computer replaces the numerical control device originally composed of hardware logic circuits, the storage, disposal, operation, logic judgment and other control functions of the input operation commands can be realized by computer software, and the micro instructions generated by the disposal are transmitted Drive the servo motor or hydraulic actuator to drive the equipment. Conservative mechanical processing is done by manually operating ordinary machine tools. During the processing of the machine, the machine tool is cut by hand and the metal is cut. The precision of the product is measured by calipers and other tools. Modern industry has long used computerized digitally controlled machine tools for CNC machine tools. The technical staff automatically edited any products and parts directly in advance. This is called CNC machining. “CNC machining is widely used in any field of mechanical machining, and it is also the development trend of mold machining and important and necessary technology. means.
