Has anyone wound a compression spring using Mach 3/4?
The general steps would be to snag the 2mm piano wire on the spring winding arbor that is in the spindle, start the spindle and then use a threading code to move the tool post to get the required spring pitch. The problem is that it takes at least 10 seconds for S TRUE to reach the required rpm that matches my spring feeder tool post feed rate. In that span of time, the wire coils around the arbor many times before the tool post even starts to move. I tried building a rod to snag the wire so that when the correct S TRUE was reached I would insert the wire and hit CYCLE START. But, the wire is just being deflected at that speed. The only alternative is to groove the thread on the arbor and then hand wind the coil to fit the grooves. Any ideas?
