Introduction to CNC Machine Tools

Numerical Control technology is also called computer numerical control (CNC, Computerized Numerical Control), which is the use of computers to achieve digital program control technology. This technique uses the computer to perform the function of controlling the motion trajectory of the equipment and the operation sequence logic of peripherals according to the control program stored in advance. Due to the use of computer to replace the original numerical control device composed of hardware logic circuit, the storage, processing, calculation, logic judgment and other control functions of input operation instructions can be completed by computer software, processing generated micro instructions are transmitted to the servo drive device to drive the motor or hydraulic actuator to drive the equipment to run.

Traditional machining is the manual operation of ordinary machine tools, processing with hand mechanical tools to cut metal, rely on the eye with calipers and other tools to measure the accuracy of the product. Modern industry has long used computer digitally controlled machine tools for operations, CNC machine tools can automatically process any products and parts directly in accordance with the program prepared in advance by technicians. This is what we call CNC machining. CNC machining is widely used in any field of all machining, but also the development trend of mold processing and an important and necessary technical means.

CNC lathes, also known as CNC lathes, that is, computer digital control lathes, is the largest domestic use, the most extensive coverage of a CNC machine tool, accounting for about 25% of the total number of CNC machine tools. CNC machine tools are mechanical, electrical, hydraulic, pneumatic, microelectronics and information technology as one of the electromechanical integration products. It is a working machine with the advantages of high precision, high efficiency, high automation and high flexibility in mechanical manufacturing equipment. The technical level of CNC machine tools and its percentage in the output and total ownership of metal cutting machine tools is one of the important indicators to measure the overall level of national economic development and industrial manufacturing of a country. CNC lathe is one of the main varieties of CNC machine tools, it occupies a very important position in CNC machine tools, for decades has been the world's general attention and has been rapid development.
