我车间化工用泵的维修,每更换一个U型密封圈,要丢掉一套不锈钢圈座,浪费极大。用聚四氟乙烯高温硬模压制法加工U型圈,要建立一整套塑料加工用的设备。我们不是专业厂,此方法行不通。在不断摸索中,找到了一种比较简便的加工方法,即用大前角组合刀具的方法,可以较好地完成聚四氟乙烯的密封圈加工任务。刀具装夹及加工方法如下: 用一对组合刀具,一次在四方刀架上装好五把车刀,再将聚四 I workshop chemical pump maintenance, every replacement of a U-ring, to lose a set of stainless steel ring seat, a great waste. Polytetrafluoroethylene high-temperature hard-pressed method of processing U-ring, to establish a complete set of plastic processing equipment. We are not a professional factory, this method does not work. In continuous exploration, found a relatively simple processing method, that is, with a combination of large-angle tool method, can be completed PTFE sealing ring processing tasks. Tool clamping and processing methods are as follows: with a pair of combination of tools, once installed in the four turret five lathes, and then poly four
