Metal-cutting machine tools is the transformation of human nature in the production of long-term practice, the continuous improvement of production tools based on the emergence and development of.
Since the 20th century, the emergence of transmission gears, so that the structure and performance of machine tools there has been a fundamental change. With the electrical control, hydraulic transmission, such as the emergence of science and technology and its application in the universal application of machine tools to machine tool technology have developed rapidly; In recent years, electronic technology, computer technology, information technology, laser technology, such as the development and applications in machine tools, machine tools has been so rapid development. The rapid development of new technologies and the objective requirements of the diversity, determined the variety of machine tool must, therefore, not only of modern machine tools to ensure accuracy, efficiency and high automation, there must be a certain degree of flexibility, that is flexibility, so that it can be easily like to adapt to changes in processing.
CNC machine tools in recent years for its high accuracy, high productivity, high flexibility to adapt to small and medium-sized wholesale production more and more attention. As the need for manual operation of CNC machine tools, but by a CNC machining process is complete the cycle, adjusting the convenience and flexibility to adapt to the product, making volume production of small and medium-sized automation possible.
CNC machine tool technology also changes the structure of the weight. Main drive system to adjust the use of DC or AC motor, the spindle to achieve stepless speed regulation and simplify the transmission chain. The use of AC variable frequency technology, speed range up to more than 1:10, spindle speed of up to 75000r/min. Machine tool feed system is usually driven by AC servo motor ball screw feed drive to achieve, to simplify the structure. In order to enhance work efficiency, fast-forward speed of the current up to 60m/min. Cutting feed rate has reached 6 ~ 10m/min. Japan developed the ultra-precision numerical control cars, and its resolution of 0.01um, roundness error of 0.03um. Machine Tool Machining Center is now positioning accuracy up to 1.5um table full itinerary, NC turntable control precision of one ten thousandth degrees. In recent years, continuously improve the reliability of CNC machine tools, numerical control devices working hours MTBF of 10,000 hours on. This shows that CNC rapid technical development. Application of CNC machine tools to improve the skill level of machine-building industry.
Skill level and performance in the gap is also evident. Abroad to do the 15-19 axis resolution in 0.1-0.01um, and can only do my 5-6 axis resolution in 1um, NC machine tools are not enough quality and reliability and stability, especially the development of advanced numerical control system and the need for further efforts to develop; basic theory and application of machine technology has clearly failed, the technical quality of staff can not catch up with the rapid development of modern machine technology needs.
China's CNC machine tools to the growing demand of domestic market demand, so China's machine tool enterprises must work hard to expand the technical team to improve the technical quality of learning and the introduction of foreign advanced science and technology in order to drive as soon as possible on the world's advanced level.
