hi Keith
about this build
i stuck with the DC spindle motor and drive (siemens as u say) as there is little wrong with them as plenty of power and fast response stopping etc
if the drive did fall over i think i might just grab a new DC drive for it in truth. control techniques or something i guess
Axis
one CHNC shown on page 1, stil has the stock Siemens as it was the first superslant i did, and at the time we talked about putting new AC motors on it but we just needed it back up and running as both machines where out of action at the time from the PSU issue
Siemens they are ok, but not grate and are on there last legs, the brush housing are warn which gives problems plus the drives them self's are abit on there last legs too. and pricy to fix most of the time.
the Green superslant on this thread or a new one we fitted new AC motors and drives fitted, 1KW units and 1:1 gearing not the stock 2:1 so now does 10m/min rapids not 5m
not much in the machining time tho when you keep tings close to the spindle tooling wise. but runs alot smoother with ACs soon i will update the other machine to AC motors also
if changing motors the trick is finding a motor that will fit on the X slide on the top, i had to mount it facing up,, not like stock motor facing down .. even then it was close on the guard ill get motor dimensions for you later might help you
as for my background,
yes i had studied electronics in education but also i had fixed the boards in these and other machines many times so had a good background in the working and understanding of the machine and how things worked before i started
so if u can follow a wiring diagram and understand what is what and how to wire to it you will be fine i would say.
plus u have the benefit someone has already done it and knows what is what
also i had done our VMC Leadwell 550 before which was probably worse than the superslant as i had very little wiring diagrams and no interface info for the drives (mirsubishi) as they did not help at all..
all my machines where done on a as time permitted while doing other things in the workshop as we are a CNC machine shop, probly spent afew hours aday on it, longest job on the superslant is the rewire i did on the 25pin sockets to interface to it some what nicely. try make it abit more plug and play... depends what you try and do with all the mass of cables in the control cabinet
