Ok let the spending vast amounts of money begin...
Ive decided to get a new mill...is this a good idea? Anyways for £3.5k I can get a BP copy - see this link:

Ive ordered 4x Reliance Electric DC Servo motors (3 for the machine, one for the rotary table when I decide to spend more money) from a guy in the states who will ship them over to me - $509 They have 500line quad encoders. Does that mean 500 pulses per rev? They spin at "Nominal Speed Rating: 1750 RPM" so geared 2:1 that make 875rpm at the leadscrew. What would that mean in terms of IPM?
OT: Whats a VFD?
They have a torque Constant, kt = 5.5 lb/in/Amp so Im looking at Geckodrives to power them at 7A max, 38.5lb/in (616oz/in) if all is good.
Im on the Nook Industries website...what specific ballscrew am I looking for?
I have also found a supplier of aluminimum stock near to me so when I get the machine I can cut parts for the conversion
Im feeling more confident now about what I need and how to get it.
Cheer,s
