我们车间过去加工图1所示薄壁管件,系在 C318型六角车床上进行,用卡管夹持约600毫米长的管料,工人一手托着高速旋转的管料,一手握住带定位块的无齿铣刀进行切割(如图2示)。这种割料方法虽然工具和设备简单,但由于管件壁薄,往往割扁或划伤,割口毛刺较大,废品率高达百分之十左右。特别 Our workshop used to process the thin-walled pipe fittings shown in Figure 1, which was made on the C318 hexagonal lathe. The pipe was used to hold about 600 mm long pipe material. The workers held the pipe material rotating at a high speed in one hand and the pipe with the positioning block Of toothless cutter cutting (Figure 2). Although this tool cutting method and equipment is simple, but the pipe wall thin, often cut flat or scratched, cutting burr larger, rejection rate of up to about 10%. especially
