the spindle / tooling arent a draw bar like on a bridgeport, they have
pullstuds in the back, which get grabbed by some kind of mechanism inside
the head, im still curious to see how it goes about doing it, I know its
spring tensioned and hydraulically released.
the amps look identical at a glance, im on lunch break so im tryin to keep
it quick. the motors are all directly connected to the amps, thats why i
thought to send the quadrature to both emc and the amp.
there are aluminum strips along the ways, i havnt seen any connectors on
them where they would be scales, but it's a possibility. If i go to the
town where the machine is I'll try to remember to get the camera and some
pictures.
Thanks again for all the help, its REALLY appreciated
Jim
