Help needed, advice on dismantelking baring holder/ballscrew

[GEOFFREY]

It is possible to get generators that will give a stabilized pure sine wave output, but I do not know if that would be economic with such a large power output. I think that even running a rotary inverter is likely to be too much for your normal domestic supply (I once ran a 3PH 4HP saw on my normal domestic single phase supply, saw worked fine, but whole house lights flickered on saw start up and I figured that the rest of my street that were on the same phase probably had the same problem!!!). Are you sure your Z axis is hydraulic? My machine has an air ram to counter balance the spindle and the auxiliary drilling heads have pneumatic plunge. The main Z axis has profiled rails and a ballscrew.Whilst I generally think "if it aint broke, don't fix it", as your usage seems to be very specialist I wonder if you would indeed be better off taking advantage of the super strong build quality of your machine mechanically and completely reconfigure the electronics to suit single phase, although that may mean downgrading the spindle power. I am glad to hear that you have good neighbours, moving that machine to the flat at the bottom of your site must have been quite difficult. G.
