On the ordinary lathe machining of the slender shaft is improving measures

On the plain lathe processing improvement measures of slender shaft is 2020 - 04 - 22 jisco spare parts in the work of factory Lu Yaoxing slender shaft is a kind of low rigidity parts, is one of the most difficult problems in mechanical processing, in the process of turning slender shaft due to weight of cutting force and the effect of rotating centrifugal force generated when such as, when turning easy bending, taper and circle bamboo-shaped defects. And turning processing continuous cutting time is too long, the tool wear is very big, difficult to get good machining accuracy and surface roughness, machining a slender shaft no matter on the precision of cutting tools, auxiliary tools, cutting parameter and the selection of cutting parameters, and process design, experience level have higher requirements, the processing method of this kind of parts and tolerance grade, length to diameter ratio has a direct relationship, also depends on its processing cost. A slender, existing problems of turning slender shaft or tube artifacts, in inertial effect and high speed machine tool, because of the cutting force, cutting heat generated by the radial force component parts bending and produce strength inside, result in bending deformation of workpiece. Due to concerns about bending deformation, rotational speed can only use low speed, low machining efficiency. Second, improve the methods and steps to design a spacer, uniform in diameter 3 threaded hole, using three bolts to adjusted to the journal, using threaded spindle back itself, on the shaft sleeve to pick on internal thread, use of internal thread, fixed and centering effect, spacer can use spiral reached a fixed tension and centering, thus ensuring the concentric and supportive. Three, after implementing effect after design, applied to the daily processing of slender shaft, solved the long slender shaft overhanging the unsafe hidden danger caused by bending, because of the increased rigidity, after some shorter, and speed can be filed, machining efficiency is improved, based in the event of slender shaft and 10 h - About 20 h, using this form when JiaGongTai province nearly half, machining efficiency is greatly improved, thus cutting tool consumption is reduced, also reduced Labour costs to a great extent, can promote the use. （ Source: utilizing the west hit the guest)
