How To Prevent Vertical Lathe Deformation?
The thermal characteristics of the Vertical Lathe are one of the important factors that affect the machining accuracy. Due to the speed of the Vertical Lathe, the feed speed is much higher than that of the ordinary machine, and the hot cutting caused by the large cutting amount has much more influence on the heat conduction of the workpiece and the machine tool parts than the ordinary machine, and the influence of the thermal deformation on the machining precision is often difficult Revision. Therefore, measures to reduce the thermal deformation of Vertical Lathes should be given special attention.
Commonly used measures are the following: 1, to improve the Vertical Lathe layout and structural design: such as the heat is relatively symmetrical use of the thermal symmetry structure; Vertical Lathe with inclined bed, flat bed and inclined skateboard structure; some Heavy-duty Vertical Lathes are thermally balanced due to structural constraints.
2, control the temperature rise: the Vertical Lathe heating parts (such as the spindle box, hydrostatic rail hydraulic oil, etc.) to take heat, air cooling and liquid cooling and other ways to control the temperature rise to heat the heat source, The use of more type of lathe to reduce the impact of thermal deformation of the countermeasure.
3, the cutting site to take a strong cold measures: in the large cutting amount of cutting, fell on the table, bed and other parts of the hot chip an important heat source. Modern Vertical Lathes, especially machining centers and Vertical Lathes, generally use multi-nozzles, large flow coolants to cool and remove these hot chips, and cool the coolant with large capacity circulation or cooling with cooling to control the temperature Rise.
4, thermal displacement compensation: prediction of thermal deformation law, the establishment of mathematical models stored in the computer for real-time compensation.
Machinery manufacturing industry after years of development, has made great achievements, of which, economic Vertical Lathe processing for the development of machinery manufacturing industry provides a favorable basis. Modern mechanical processing and manufacturing of economic Vertical Lathe put forward higher requirements, the need for economic Vertical Lathe with automatic processing function under the premise, but also with the reliability of protection, therefore, to strengthen the analysis of Vertical Lathe, Can improve the stability of the machine running, and thus can promote the development of China's machinery manufacturing industry.
The processing of economical Vertical Lathe can effectively improve the efficiency of mechanical parts manufacturing, its reliability affects the development of mechanical manufacturing technology, advanced machinery manufacturing technology, not only need to improve the use of Vertical Lathe also need to improve the Vertical Lathe Reliability, can ensure that processing can achieve a reasonable processing results, while improving the safety of processing and reduce the cumbersome operation of the steps. Improve the reliability of economic Vertical Lathe, can better promote the cause of CNC and mechanical manufacturing development, and thus can promote the development of China's industrialization process.
Economic Vertical Lathe technology affects the overall ability of our comprehensive technology, so we have to continuously improve the accuracy of Vertical Lathe processing, so as to improve the overall strength of China from all aspects.
Economic Vertical Lathe as the strategic equipment of national defense industry, is the most important means of manufacturing weapons and equipment, is an important guarantee for the modernization of national defense and military equipment. In the market demand, driven by China's Vertical Lathe industry demand will continue to maintain high growth, the domestic demand for high-end machine tools gradually more than low-grade machine, the average annual compound growth rate of 37.4%. Vertical Lathes have become the mainstream of machine tool consumption, the rapid growth of Vertical Lathe needs of the huge demand for CNC system.
In the economic development, strong support for national policies, the revitalization of upstream and downstream industries under the background, China's Vertical Lathe industry demand will continue to maintain high growth, especially the economic Vertical Lathe will usher in greater market space, the future 3 - 5 years, China's Vertical Lathe industry market growth rate will reach 12 or so. Which will drive China's domestic Vertical Lathe and its CNC system and related functional components of the market development, but also undoubtedly for the domestic CNC system manufacturers continue to develop their own technology, expand the market provides an excellent opportunity.
