Greetings,
I had trouble today with our Kerr 4X6 centrifugal casting machine.
After about 20 flasks it wouldn’t wind up anymore. I removed the top
to check to see if the spring snapped but it was fine. It all seemed
intact. I made sure the small ball bearing was in place and replaced
the top. It worked one more time then would not wind a second time.
This time being a little frustrated and thinking the ball bearing was
stuck I took a leather mallet and mildly rapped on the top cover in a
few places. It worked again for a few times then stopped. Now it
seemed to start working again after each time I rapped on the top
cover. So could it be the centrifugal mechanism was overheating and
the bearing getting stuck, I am going to try ands use Krytox grease,
a high temp lubricant, and hopefully it will fix the intermittent
problem.
My question is has anyone else had this experience and if so how did
you fix it?
Regards,
James McMurray
