我们单位使用的是沈阳无线电二厂生产的DSK—618型数控线切割机床。去年,装上了无触点开关来控制贮丝马达的换向,效果很好。在这基础上,我们又增添了贮丝马达的可控硅无级变速和能耗制动(断电自停)装置,方便了操作,进一步完善了数控线切割机床的走丝系统。下面分三部分来谈谈我们的体会,供有关方面的工作人员参考。 Our unit is using the DSK-618 CNC WEDM machine manufactured by Shenyang No.2 Radio Plant. Last year, equipped with a non-contact switch to control the storage motor motor commutation, the effect is very good. On this basis, we have added a SCR motor CVT and energy braking (power off stop) device to facilitate the operation and further improve the CNC wire cutting machine tool wire system. Here are three parts to talk about our experience, for the reference of the staff concerned.
