Research On Cutting And Assembling Technique Of GMB20m5× Gantry Moving 5-axes Maching Center

Gantry CNC machine tool (GCNC-MTs) products of China are lack of competitive capacity all the time. So the industrial requirement for GCNC-MTs depends on imports long-term. According to the statistics from China Customs, The cost for the purchase of gantry CNC machine tools is about 42% of the total China's annual imports of CNC machine tool. The GCNC-MTs are concerned with China's national defense and security. In the current international situation, it is of strategic significance to encourage and require the enterprises of machine tools in China develop gantry CNC machine tools. The project is of great importance for Liaoning to upgrade his prestige in the country and revitalize the old northeast industrial base.At the present, several machine tool enterprises in China have developed 5-axis linkage CNC machine tool, which has broken the blockade of foreign technologies. However, the 5-axis linkage CNC machine tools made in China are still unable to answer for the practical application in terms of precision, performance and reliability, and even impossible to compete with foreign developed countries. Therefore, such a kind of machine tools relies on import long-term. On the other hand, the import of this kind of machine tools is limited by the developed industrial countries for the purpose of the blockade. Meanwhile, the price of machine tools is very expensive. These factors greatly constrain the development of the manufacturing technology in China, and also make a serious impact on the further development of aviation, aerospace, military, mould, scientific research, precision instrument, a high-precision medical equipment etc.. To break this pattern, China should instantly develop 5-axis linkage machine tools with high quality as soon as possible. Meanwhile, to revitalize old industrial bases in the northeast of China, our enterprise resolve to develop the 5-axis GMB20m5x gantry machining center with the world's advanced level. The successful design of the gantry CNC machine center tool will improve the manufacturing level of CNC machine tool, will also make the contribution to raising the overall level of China's equipment manufacturing industry.The development of 5-axis GMB20m5x gantry machining center requires a extremely high performance in process, assembling and etc. The machine center is the basis of performance, accuracy and reliability of machine tools. The thesis mainly researches the technology processing and the assembly aspects of the 5-axis GMB20m5x gantry machining center.
