1、 1 The design of 350 CNC machine Tailstock Hydraulic system Abstract: The main purpose of the research is based on 350 CNC machine tools to design requirements, designed to match its hydraulic Tailstock to meet the rotation accuracy, rigidity, temperature rise, and so on seismic requirements, to enh

2、ance the overall performance of machine tools. To accomplish this design, I collected and analysed the information before the design, including domestic and international development of CNC machine tools; hydraulic system of hydraulic technology and the basic information; equal hydraulic machine Tai

3、lstock the drawings and information . Then is tentatively determined the overall layout of hydraulic Tailstock, including the allocation of form, layout and the hydraulic system of hydraulic energy, and select the appropriate matching components, such as. This was followed by the main Tailstock the

4、design and calculation. CNC machine Tailstock top tight and movement is basically manual control, in the conventional process, the change required manual. Therefore, in the process of CNC machine tools in efficiency is not high, workers in labor intensity and great. Therefore, the issue of the Insti

5、tute to achieve the desired results in the 350 CNC lathe processing, when the need to use Tailstock, the use of this issue by the Tailstock design can improve the process of mechanization and automation level, increase production efficiency and reduce Workers in the labor intensity. Key words：Numeri
