我厂生产的普通车床的四方刀架是采用底面的弧形槽来定位的(如图1所示)。这种弧形槽原来的加工方法,生产率低,质量较差。为此。我们在立式铣床上作了一种专用靠模装置,用来加工这种定位槽,效果很好。它可使工件光洁度达▽6,等分误差在±5’的范围内,符合图纸加工要求,提高生产率10倍左右,在改换转盘后,还可以加工其他弧形槽。 I plant production of ordinary lathe square turret is the bottom of the arc slot to locate (as shown in Figure 1). This arc groove original processing methods, low productivity, poor quality. to this end. We have made a special type of vertical die-making machine, used to process this positioning groove, the effect is very good. It can make the workpiece finish up to ▽ 6, the error within ± 5 ’, in line with the drawings processing requirements, improve productivity about 10 times, after changing the turntable, you can also process other arc groove.
