Anybody know how involved it would be to covert to cnc control please ?

[Jim Dawson]

It would be a lot of work and a lot of custom parts. It is possible, but maybe not practical. If you have other machine tools to build parts it might be an interesting project.

Not practical for what reason ?. I dont have any tools with me atm. But have a price from someone I know (1400 nzd$) for all parts except motors/belts, electronics which i can do

Not sure if its poss to add a Variable speed control to it though ?

[Jim Dawson]

It's an old slow speed machine. That in itself is not horrible but won't have the performance Bridgeport style machine. It looks like the vertical spindle is fixed so the only Z movements possible are by the knee. On the other hand, take off the vertical spindle and use the horizontal spindle and you can do some serious metal removal with that old beast.

Don't know what you are going to get into when installing ball screws in that, but you will want to use ball screws that are at least as big as the lead screws that are in it now.

It is certainly possible to add speed control by using a VFD.
