In the late 1950s, the United States established a world machining center. Today, the machine tool manufacturing industry has entered the era of CNC machine tools. In terms of scientific research, design, production and application of CNC machine tools, the United States, Germany and Japan are the best in the world, and they also have the richest work experience. Because of their different levels of social development, each has its own characteristics.
1. The time of using CNC machine tools in the history of the United States
The government attaches great importance to the production of machine tool industry. Due to the needs of national defense, the Ministry of Foreign Affairs and other departments have constantly clarified the development prospects of machine tools, scientific research development, surplus assets, and excellent talents in the Internet era. They attach great importance to "high efficiency", "independent innovation", and scientific research in basic disciplines. As a result, machine tool technology innovations, such as the development and design of the world's first CNC machine tool in 1952, the establishment of a processing management center in 1959, the FMS in the early 1970s, and the first open CNC machine tool in the 1980s.
In the last century, there was specific guidance from the government under pressure in the 1980s, which led to slow growth in the output of CNC machine tools. By 1982, they were replaced by backward Japan and imported in large quantities. Since the early 1990s, past mistakes have been corrected, the maturity of CNC machine tool technology has improved, and the output has gradually increased.
2. The development of German CNC machine tools in history
On many levels, the German government attaches great importance to and vigorously supports the production of machine tool industry, and has important strategic significance. After the successful development of the first CNC machine tool in 1959, Germany attached great importance to scientific experiments, closely integrated theoretical research, and also attached great importance to basic scientific research and applied science and technology research.
Germany attaches great importance to the innovation and application of CNC machine tool servers and components. Its mechanical, electrical, hydraulic, pneumatic, optical, CNC blades, precision measurement, CNC machine tools, and various functional components rank first in the world in terms of quality and performance. For example, Siemens PLC CNC machine tools are among the best, vying to buy.
3. Japanese CNC machine tools in history
The relevant departments of the Japanese government attach great importance to the development trend of the machine tool industry. Starting from the overall planning, policies and regulations (such as "Equipment Vibration Law", "Mechanical Engineering Law", "Machinery Processing Law", etc.), the development trend of the machine tool industry has been carried out. Specific guidance. The focus of learning for Germans is the learning and training of outstanding talents and machine tool parts, and the learning and training of quality control and CNC machine tool technology for Americans, even getting rid of Biyulan.
Since the first development of CNC machine tools in 1959, the output of CNC machine tools in 1978 (7342 units) has surpassed the output of the United States (5688 units), and the output and output have been ranked first in the world (46604 units in 2001, 27409 units exported, export 59%).
4. China's current situation
At present, the development trend of CNC machining technology in China originated in the 1950s. Through the introduction of CNC machining technology during the "Sixth Five-Year Plan" period and the organization, digestion and absorption of the scientific and technological innovation plan during the "Seventh Five-Year Plan" period, excellent results have been achieved in China's CNC machining technology and CNC machine tool manufacturing industry.
In recent years, China's CNC machine tool industry has developed rapidly. From 1998 to 2005, the output and consumption of CNC machine tools in China increased by 39%, 3%, and 34% annually. Nevertheless, the development potential of imported machine tools is still great. Since 2002, China's CNC machine tools have become the world's most consumed machine tool for three consecutive years.
The CNC machine tool performs fully automatic processing of parts in accordance with a predetermined processing procedure. Put the processing route of the part, the main parameters of the processing technology, the trajectory of the CNC blade, the offset, and the main parameters and functions of drilling together. Types of CNC blades for CNC machine tools.
According to the instruction code of the CNC machine tool and the program flow file format, write the program flow into the program flow sheet, and record the content of the program flow sheet on the operating materials, and then input the CNC machine tool equipment of the CNC machine tool to process the parts of the machine tool. Give specific instructions. CNC machine tools are the general term for CNC machine tools. Fully automated machine tool and program control system software. The automatic control system can logically decode and encode the program flow through operation codes or other label commands, so that the machine tool can move and solve part problems.
Compared with ordinary machine tools, CNC machine tools have the following characteristics:
CNC machine tools have high processing accuracy and stable processing quality; CNC machine tools have smooth coding.
It can carry out multi-coordinate number linkage, and can process complicated-shaped parts; intelligent CNC carpenter machine tools.
The change of machining parts generally only needs to change the program flow of the CNC machine tool, which can save management time on the production site;
The machine itself has high precision and good rigidity. You can choose a machine tool with a large amount of processing and high production efficiency (generally 3 to 5 times that of ordinary machine tools); German CNC machine tool processing video.
The degree of automation of machinery and equipment is high, and labor productivity is reduced;
The quality of employees is high, and the technical level of maintenance personnel is also high. Two machining center shelves can be configured:
Unique stand: developed and designed by the CNC lathe manufacturer, the use of a rocker is also unique.
General purpose special tool framework: Based on some general specifications, the machining center manufacturer can choose the configuration of the machining center according to the role of the specification.
