With the rapid development of science and technology and social production, mechanical products are becoming increasingly complicated, and the requirements for the quality and productivity of mechanical products are getting higher and higher. The automatic CNC machining process is the most important means to intelligently adapt to the above development characteristics. Among the industries such as aerospace, military industry, and computers, parts have high accuracy, complex shapes, small batches, regular changes, difficulty in processing, low production efficiency, large labor intensity, and difficult to guarantee quality.
1. CNC machine tool
The composition of CNC machine tools is mainly divided into three parts: machine tool body, transmission system and CNC system.
The main body of the machine
The main part of the machine tool is the main component of the machine tool, the hardware of the machine tool, an important mechanical attachment of the machine tool, and the part that is easy to see intuitively with the naked eye, including the bed and base casting, the spindle and gearbox, guide rail and sliding, lubrication, crumbs, crumbs, crumbs, and ducts. And cooling, etc.
Transmission system
The transmission system is an important context of CNC machine tools. The work tasks of machine tools are completed, including tools, transmission machinery and auxiliary power systems.
(1) The tool part includes a protective device, a knife library and a knife change device.
(2) As a part of the second part of the transmission system, the transmission machine includes the three parts of the roller script, the straight wire guide and the association.
(3) The auxiliary power system includes two parts: hydraulic system and starting system, which is the power of CNC machine tools.
CNC system
CNC systems can be said to be the soul of CNC machining tools, the perceptual part of the entire machine tool, and the essence of various functions and operations of the machine tool. CNC systems are basically divided into two categories:
(1) Driving device includes high -speed spindles, rectangular motors, linear motors, ordinary motors and step motors;
CNC machine
2. CNC machine tool technology chain
CNC machine tool technology chain is composed of six parts: real -time nuclear nuclear technology, direct driving processing control technology, servo motor processing control technology, linear sensor resolution technology, angle sensor resolution technology, and CNC system on -site bus technology
3. CNC machine tool product chain
The product chain of CNC machine tools is longer than other links, including processing centers, metal cutting, special processing, molding, etc.
CNC machining center: multi -axis linkage and flexible processing unit.
Metal cutting: CNC lathes, CNC milling machines, CNC beds, CNC drilling machines, CNC grinding machines and CNC punch.
Special processing: Electric flame cutting machine, electric spark molding machine, flame cutting machine, laser processing machine, high -voltage water cutting machine, CNC automatic welding equipment.
Molying machine tools: CNC punch, CNC shear, CNC bending machine, CNC bending machine, multi -coordinate measuring machine.
Others: automatic drawers, industrial robots and special CNC systems.
4. downstream industrial chain of CNC machine tools.
The downstream industrial chain of CNC machine tools reflects all the functions of CNC machine tools as the parent, and is widely used in various industries in the manufacturing industry. Generally, it includes the following points:
National Defense Forces: Aerospace, nuclear industry, ship industry, weapon manufacturing.
Petroleum chemical industry: petroleum, petrochemical, chemical industry, etc.
Shipbuilding: Ship repair is related to the ship.
Mechanical industry: mechanical manufacturing.
Automotive industry: body processing, cylinder processing, transmission, clutch, shaft parts, etc.
Other industrial manufacturing areas.
The number of machine tools in a country reflects the level of the national machine tool industry and machinery manufacturing industry, and it is also one of the important signs to measure scientific and technological progress in a country. It is of great significance to realize the automation of production process, promote scientific and technological progress, and accelerate modernization. Developed countries visual control technology are the strategic focus of the development of the machinery industry, and vigorously promote and develop CNC machine tools.
