Introduction To CNC Lathe Mechanism

Numerical Control (English name: Numerical Control for short: NC) technology refers to the technology that uses digital instructions composed of numbers, characters and symbols to realize the action control of one or more mechanical equipment. Numerical control is generally achieved through the use of general-purpose or specialized computers for digital program control, hence CNC, also known as Computerized Numerical Control (CNC), is commonly referred to as CNC in foreign countries, and the concept of NC is rarely used again. It usually controls mechanical quantities such as position, angle, speed, and switch quantities related to the flow of mechanical energy. The emergence of CNC relies on the emergence of data carriers and binary data operations. In 1908, perforated metal sheet interchangeable data carriers were introduced; At the end of the 19th century, control systems with auxiliary functions were invented using paper as a data carrier; In 1938, Shannon conducted rapid data computation and transmission at the Massachusetts Institute of Technology in the United States, laying the foundation for modern computers, including computer digital control systems. Numerical control technology has been developed in close combination with machine tool control. In 1952, the first CNC machine tool was introduced, becoming a landmark event in the history of the world's mechanical industry and promoting the development of automation.
CNC technology, also known as Computerized Numerical Control (CNC), is a technology that uses computers to achieve digital program control. This technology uses computers to perform logical control functions on the movement trajectory of devices and the operation timing of peripherals based on pre stored control programs. Due to the use of computers to replace the CNC devices originally composed of hardware logic circuits, various control functions such as storage, processing, calculation, and logic judgment of input operation instructions can be achieved through computer software. The generated micro instructions are transmitted to the servo drive device to drive the motor or hydraulic execution component to drive the equipment to run.
Traditional mechanical processing is done by manually operating ordinary machine tools. During processing, the mechanical tools are shaken by hand to cut metal, and the accuracy of the product is measured using tools such as calipers with the eyes. Modern industry has long used computer digitally controlled machine tools for operations, and CNC machine tools can automatically process any product and component according to pre programmed programs by technicians. This is what we call CNC machining. CNC machining is widely used in any field of mechanical processing, and it is also a development trend and an important and necessary technical means for mold processing.
CNC lathe, also known as CNC lathe, is the most widely used and widely covered CNC machine tool in China, accounting for approximately 25% of the total number of CNC machines. CNC machine tools are electromechanical integrated products that integrate multiple technologies such as mechanical, electrical, hydraulic, pneumatic, microelectronics, and information technology. It is a machine tool in mechanical manufacturing equipment that has the advantages of high precision, high efficiency, high automation, and high flexibility. The technical level of CNC machine tools and their percentage in the production and total ownership of metal cutting machine tools are important indicators to measure a country's national economic development and overall level of industrial manufacturing.
