Re: [CAD_CAM_EDM_DRO] Re: Taig CNC mill .......and Emco

Refering to the extract below, we have some emco machines at work after
taking over another small firm. They are red and grey..... the servo lathes
are ok, a small 5 phase stepper lathe works ok but two FB100 mills with
similar controls to the stepper lathe still dont work despite sent away
professionaly repaired driver boards (sent back again still no go) They just
pop power fets, we had there engineer in but no joy. any new list members
got any clues? (these two mills worked in there previous location but were
never switched off, something to do with a generaly damp area and
condensation.) there is also a third which is kept for spare parts. If my
boss gives up on them ill make an offer for one but I am sort of moraly
obliged to help get them going although its not realy my job. I think to be
of use at work they would need to go at least as fast and accurate as
original spec. I have said its possible to retrofit them but I dont think
they would go for it (pressures of time and getting work out) so any similar
problems with a solution? or should I just start clearing a space in my shed
in anticipation :-)
One had soluble leaked into y axis motor but still blew a fet after swapping
the motor, I think it realy needs info on how they current limit and exactly
what happens on switch on, how they decide to zero themself etc, I didnt get
a chance to talk to the engineer but if he knew they should be fixed anyway.
(I believe they were made in the 1980s)
