Numerical control (abbreviation: NC) technology refers to a technology that uses digital commands composed of numbers, characters and symbols to control the motion of one or more mechanical equipment. Numerical control generally uses general-purpose or special-purpose computers to realize digital program control. Therefore, numerical control is also called Computerized Numerical Control (Computerized Numerical Control), or CNC for short. It is generally called CNC abroad, and the concept of NC is rarely used. What it controls is usually the position, angle, speed and other mechanical quantities and the switch quantity related to the flow of mechanical energy. The generation of numerical control relies on the appearance of data carriers and binary data operations. In 1908, a perforated sheet metal interchangeable data carrier came out; at the end of the 19th century, a control system with paper as a data carrier and auxiliary functions was invented; in 1938, Shannon conducted rapid 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. Numerical control technology is 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 machinery industry and promoted the development of automation.

Numerical control technology is also called Computerized Numerical Control (CNC, Computerized Numerical Control), which is a technology that uses computers to realize digital program control. This technology uses a computer to execute the sequential logic control function of the movement track of the device and the operation of the peripherals according to the control program stored in advance. Because the computer is used to replace the original numerical control device composed of hardware logic circuits, the storage, processing, calculation, and logic judgment of input operation instructions can be realized by computer software, and the microscopic instructions generated by the processing are transmitted to The servo drive device drives the motor or hydraulic actuator to drive the equipment to run.

Traditional mechanical processing is performed by manual operation of ordinary machine tools. During processing, the mechanical tool is shaken by hand to cut metal, and the accuracy of the product is measured by the eye with tools such as calipers. Modern industry has already used computer digitally controlled machine tools for operations. CNC machine tools can automatically process any products and parts directly in accordance with the procedures programmed by technicians in advance. This is what we call CNC machining. CNC machining is widely used in any field of all mechanical machining, and it is the development trend and important and necessary technical means of mold machining.

CNC lathes, also known as CNC lathes, are computer numerically controlled lathes. They are the most widely used CNC machine tools in China, accounting for about 25% of the total number of CNC machine tools. CNC machine tools are mechatronics products that integrate multiple technologies such as machinery, electricity, hydraulics, pneumatics, microelectronics and information. It is a machine tool 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 their percentage of metal cutting machine tool output and total ownership is one of the important indicators to measure a country's national economic development and the overall level of industrial manufacturing. CNC lathe is one of the main varieties of CNC machine tools. It occupies a very important position in CNC machine tools. For decades, it has been generally valued by countries all over the world and has been rapidly developed.

Since the advent of CNC lathes in the 1950s, due to the use of CNC lathes to process complex-shaped parts in single-piece production and small batch production, it has not only improved labor productivity and processing quality, but also shortened the production preparation cycle and reduced the skill of workers. Proficiency requirements. Therefore, it has become an important development direction for realizing technological innovation and technological revolution in single-piece, small-batch production. Countries around the world are also vigorously developing this new technology.

We know that for mass-produced parts, the use of automated and semi-automated lathes can already automate the production process. However, for single-piece, small-batch production parts, achieving automation has always been a problem. For a long period of time in the past, it has always been unable to solve the problem satisfactorily. Especially for parts with complex shapes and high precision requirements, they have been at a standstill on the road to automation. Although some application profiling devices have solved part of it, practice has proved that profiling lathes still cannot completely solve this problem.

The emergence of CNC lathes (machine tools) has opened up a broad way to fundamentally solve this problem, so it has become an important development direction in mechanical processing.

CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process the programs with control codes or other symbolic instructions, and decode them, so that the machine tool can operate and process parts.

Compared with ordinary machine tools, CNC machine tools have the following characteristics:

●High processing precision and stable processing quality;

●Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed;

●When machining parts change, generally only need to change the CNC program, which can save production preparation time;

●The machine tool itself has high precision and high rigidity, can choose a favorable processing amount, and has high productivity (generally 3~5 times of ordinary machine tools);

●The machine tool has a high degree of automation, which can reduce labor intensity;

●Higher requirements for the quality of operators and higher technical requirements for maintenance personnel.

Selection principle of CNC lathe

Preliminary preparation

Determine the process requirements of typical parts and the batch size of processed workpieces. The function that the CNC lathe should have is to make preparations and the prerequisite for the reasonable selection of CNC lathes: meet the process requirements of typical parts.

The process requirements of typical parts are mainly the structural size, processing range and accuracy requirements of the parts. According to the accuracy requirements, that is, the dimensional accuracy, positioning accuracy and surface roughness of the workpiece, the control accuracy of the CNC lathe is selected. Choose based on reliability. Reliability is a guarantee for improving product quality and production efficiency. The reliability of a CNC machine tool means that the machine tool runs stably for a long time without failure when it performs its functions under specified conditions. That is, the mean time between failures is long, even if there is a failure, it can be restored in a short time and put into use again. Choose machine tools with reasonable structure, excellent manufacturing, and mass production. Generally, the more users, the higher the reliability of the CNC system.

Machine tool accessories and tools

Machine tool accessories, spare parts and their supply capacity, cutting tools, are very important for CNC lathes and turning centers that have been put into production. When choosing a machine tool, carefully consider the compatibility of tools and accessories. Turning center

Control System

Manufacturers generally choose products from the same manufacturer, and should at least purchase control systems from the same manufacturer, which brings great convenience to maintenance. In teaching units, it is a wise choice for students to choose different systems and be equipped with various simulation software because they need to be knowledgeable and knowledgeable.

Choose between performance and price

Make sure that the functions and accuracy are not idle, not wasted, and do not choose functions that have nothing to do with your needs.
