我们在大修机床中,自制了一套镗削尾架孔的工具。这套工具如图所示,使用时将尾架固定在车床床面上,这样就减少了镗削时工件的自由浮动,提高了镗孔的精度。主轴套2的内孔要稍留余量,把主轴套装在主轴1上以后,再将套2的内孔精镗到与镗杆成滑动配合,固定座⑦夹在刀架上,将镗杆推入主轴套中,用百分表校正镗杆后,即可进行加工。 We overhaul the machine, made a boring tailstock hole tool. The tool shown in the figure, when used to the tailstock fixed to the lathe bed, thus reducing the free float when boring workpiece, improve the accuracy of boring. Main bore sleeve bore to a margin, the spindle set in the spindle after 1, and then set the inner hole of the sleeve 2 fine boring with the boring bar into a sliding fit, fixed seat ⑦ clip on the turret, the boring bar into In the main shaft sleeve, calibrate the boring bar with the dial indicator to finish the machining.
