I have a OS Walker chuck with a Minatron control that will not always release parts. I finished up a part the other day, had a really nice grind on both sides of a die detail, and it wouldn't let go. I wound up having to beat the thing off with a dead blow and scratched up my nice grind. That was AFTER turning it back on at 0.
To be completely honest, I do not know anything about electromagnetic chucks. I have always had a "mechanical" magnetic chuck in my shop, though I have used many surface grinders with electromagnets.... they always let go.
So where does one start?
I found several threads discussing WEAK magnets, which this is absolutely not.
One thread mentioned checking the connections. Will take it apart and check connections.
Control is 120v, 2amps, DC 0-115, 1.3amps
