What 'decent' Milling machine?

[Chaz]

Depends on how old and what's inside.? Often if converting your better just replacing control and the drives with modern stuff. You'll have a far better performing machine.

The AC Transformer can be re-used but often the Caps and Bridge rectifier are on one of the boards your removing so you'll need to make a little board with new caps etc or use another PSU.
For this reason I prefer to use a new often higher voltage toroidal supply has the steppers are often well under performing. Along with smaller Switch mode PSU for Relays etc to save messing around with differant size Caps etc for differant DC voltages required. The stock transformer gives several AC voltages.

The Spindle speed controller can be re-used but you'll need Controller or BOB that can provide 0-10V signal.

The Contactors and Relays can often be reused, as can most of the other bit's n bobs inside.!

Not difficult to do but Not something I'd encourage anyone who as NO experience to take on.!!

Thanks. Understood. I'm happy to do the electronics, sounds like a perfect match for a lot of new kit.

Trying to find some details of the spindle etc to see if it matches what I need in terms of speed / power.
