Make a few quick change knife holders, I think I found a better way!

Then, I tested each link in turn, and finally it was the conductive block that led to the interruption of high-frequency power supply, and indirectly led to the inaccurate signal of the detection voltage feedback to the system, so it could not be cut normally.
I decided to make a conducting electrode structure myself.

I decided to make a conducting electrode structure myself.
I happen to have some broken alloy drill bits, and only the shank part is intact. I cut it into short cylinders, and then I disassembled a fuse holder and took a conductive reed to use. In order to reduce the volume, I cut and solder the new reed.

The lathe turns the insulating rod into a supporting base, the file changes the round hole into a square hole, the reed is placed in and filled with sealant (preferably using insulating glue), and then waits for it to set and clean up.QQ截图20240515155513.jpg

The next day, the working arm of the machine is drilled, wired, installed, and then the alloy column is installed, and the test begins!

The spark becomes stable and the feed begins to advance steadily.
Test cutting 10 hours, make a knife slot, smooth and smooth, accurate size. The current state should be qualified,

Looks like you're making good progress. Those parts look nice. That's an amazing process.
