电火花计时器同电磁打点计时器相比,使用方便、性能稳定,但使用时能节约耗材就更好了,我们对电火花计时器进行了小小的改动就达到了这一目的。取下电火花计时器导电纸的上盖,取出导电纸,如图1所示,A、B是同一电极,B还有导电纸转轴的作用,C孔内约1mm处有另一电极。工作时A和B接通导电纸,导电纸和C孔内的电极在高电压的作用下放电,电火花在纸上留下灼烧的痕迹。
Compared with the electromagnetic striking timer, the EDM timer is easy to use and has stable performance. However, it is better to save consumables when it is used. We have made small changes to the EDM timer to achieve this goal. Remove the upper cover of the EDM timer conductive paper, take out the conductive paper, as shown in Figure 1, A, B is the same electrode, B and the role of the conductive paper shaft, C hole is about 1mm at the other electrode. During the work, A and B are connected to the conductive paper, the conductive paper and the electrodes in the C hole are discharged under the action of high voltage, and the electric spark leaves burning marks on the paper.
