Hardinge Lathe CNC Retrofit/Conversion

[Chaz]

So started to look at the lathe in a bit more detail today.

The servo motors will be a direct fit exchange, courtesy of some spacers that Gary had already made. I'm not sure if the cables can be routed without taking connectors off (motor and encoder).

The spindle pulley wont work for the new spindle motor. Shaft size is now 38mm whereas on the old DC motor its around 36mm (or the nearest imperial size to that).

Found a replacement pulley / bushing which should work.

Was trying to remove the spindle 'mounting' system, removed all bolts, cant get it out. There's clearly some adhesive in places like a sealant, could be that. I'm hopeful making a adapter plate for the slightly smaller motor should be straight forward - just need to get one of my mills up and running.

I'd like to replace the V belts - any idea on how much work is involved to get them out - do I need to mess with the spindle (hopefully not).

Was fortunate to find a wiring diagram (and some notes) in the door, thanks Gary. Was looking for the limits / end stop but not found them yet - at least the drawing gives a massive help as wires / terminal blocks are marked. I believe these are all hall effect sensors so need to work out how to wire them up. I note too that there is X Coarse Home and X Fine Home marked in pencil, first time Ive seen that ..... will need to work out how to use these.
