Re: [CAD_CAM_EDM_DRO] Pratt Whitney 5 axis NC

You need to do some research first. First of all, what do you want the
machine for? Is it for 24/7 machining, a small business or home use?
Take a good look at the machine. Are the screws and slide ways in good
condition? Is it currently running? If so move all axes. If not, try to
manually move the motors. Is there any rumbling from the screws? Does
the spindle work? Are the spindle bearings ok? Parts for machines like
this are very expensive. If there is much wrong with it, it won't be
worth repairing.

As far as retrofitting it is concerened there are two main routes. You
can buy a commercial retrofit kit. This will be quite expensive but
relatively easy to fit. Alternatively you can do it yourself. This is a
lot cheaper but also a lot more work. If you are scared of wiring this
is definitely not for you! If this is for industrial use I would say go
with the retrofit kit. If it is for hobby use and you don't mind
spending many hours working on it then do it yourself. There are lots of
knowledgeable people on this list so if you have any questions, probably
someone will have an answer for you.
