图1所示为利用切制内环槽工具加工油缸角度环形槽的加工示意图。角度环形槽与内孔D同轴,而与外圆d无要求。在钻床或车床上加工角度环形槽时,是用三爪卡盘夹紧油缸外圆,这样,当油缸内外圆不同心时就无法保证加工出的内环槽能与内孔同轴。为此,以前我们补加工外圆,使内外圆同轴,但因有的缸筒较长,同轴度很难保证。现在设计的切制内环槽工具安装在钻床上使用, Figure 1 shows the use of cutting the inner groove machining tank angle annular groove machining schematic. Angular ring groove and bore D coaxial, but no requirements with the outer circle d. In the drilling or lathe processing angle ring groove, the cylinder is clamped with a three-jaw chuck, so that when the cylinders do not have different inner and outer circle can not guarantee the inner ring groove can be coaxial with the inner hole. To this end, in the past, we make up the outer cylindrical work, so that the inner and outer circle coaxial, but because of the longer cylinder, coaxiality is difficult to guarantee. Now designed to cut the inner groove tool installed in the use of drilling machines,
