Warco/ Myford mill problem

[Michael LeechParticipant @michaelleech30848]

Thank you David as you can see I can now post.

I have a Warco KF VO A1S turret mill which I think is an identical design to a Myford VM-E.

I have a squealing sound coming from the spindle pulley set. The nut holding the pulley set is circular with four indents cut in the edge at 90 degree intervals. I have tried tightening/ loosening this nut with no success. Part of the difficulty is created by the fact that the machine has no spindle lock.

Has anyone dealt with this problem before as I could do with some help with this.

I have spoken to both Warco and (new) Myford but they claim that the machine is so old they no longer have any staff that can give advice.

Squealing is usually more a sign of a slipping belt than a loose pully. Could be a dry bearing, what does the spindle turn like by hand with no belts in place.

If you have no spindle lock put a bit of 1/2" bar in a collet and hold that in the machine vice, failing that hold the collet/Autolock spanner in the vice while its engaged in the tool holder

With the belt removed and turning the pulley by hand I still get the squeal so as you suggest it may be a dry bearing, although I do lubricate at regular intervals. However I will try yor sugestion re locking the spindle.

Many thanks

Mike
