Round Head Aciera F4 Power Feed Motor Suddenly Not Running or AtLLING

drzipper · Mar 5, 2020

The power feed motor has functioned for the last 15 years. It periodically sounds like it is laboring particularly at the top of the Z feed but has always worked. There is a rise in the pitch of the motor sound. Tonight it cut out on the X axis. It has restarted after cooling off. I suspect a lubrication issue or gearing issue. Before digging in, I thought I'd ask to hear if anyone has dealt with a similar issue and what the solution was?

TIA,
David

If it's like my f5 it will have a double ended come clutch in the feed box to change between feeds and rapids. Mine has worn and started slipping so we are in the same boat. Need new friction surfaces made

Thank you,
Actually after O wrote the entire machine electrics went I traced it back to a contacter block not activation, once it contacted everything went back to normal, both motors worked.
