Help needed, advice on dismantelking baring holder/ballscrew

[george uk]

Well, we eventually got it in the workshop. Now onto the servicing.

Any pointer on best way to service rails and blocks. They have grease nipples but are hammered with fine particles, I would rather not fully disassemble if possible. Am thinking

1. warm the block, ram loads more grease through, till it runs clear, wipe residue, repeat every 2 weeks untill no trace of particles.

anyone advise or opinion on this

2. basic soapy water for the rail and machine, clean up with pure alcohol .

Also, i wander if anyone could talk me through some electronics questions in relation to the supply to this.

The machine ( scm tech 95l ..1998 ) says 400w 3p on the cabinet. Plugged into that, separate, its what looks like a huge but basic inverter ( am guessing 240v 3p to 380v 3p ).

If i wish to run this off a large genny, what extra power should i consider ( above the machine draw )

It look like it would run from both 240v 3p and 380v 3p, but the box says 400v 3p. the possible genny outputs are 240v 3p 380v 3p and 415v 3p. I understand that if i run it at 240v 3p, it will be lower powered, but maybe thats not a problem for me, What i really dont understand is

1. Is ther any benefit/loss using the inverter to go from 240-380
2. if the genny outputs 415v, would i have to invert that down to 380v
3. any advice or opinions on using a genny with a large machine.

mm, thinking, i may need to check the inverter, as it may be 415-380, but i doubt it, it looks like 220v to 380v inverter. ( the inverter looks like its SMC branded and purchased with the original machine
