TOS-KURIM CNC Upgrade

You certainly know your stuff when it comes to this! Everything I have found dated suggests it was built in the 80s (1983 was the latest date I found) so its certainly not cutting edge technology in there!! I'm glad you said to bin it all, I'm sick of the sight of the inside of that cabinet!!

I'll have a play with the transformer today, if I don't get anywhere I'll look into something a bit more suitable..

so if I went single phase and got the 100Vac, would these do to get the DC:

If single phase is the best option, would you completely get rid of the 415V and us a VFD to power the Spindle motor? or Could I still use the 3 phase supply with a relay or something to switch spindle power on from the controller? I know the controller module I bought shows a VFD on the wiring diagram so that may have to be the way to go anyway..
