I am looking at buying a sherline 5400 with the rotary table and tail stock. I already understand some of the issues with tolerances of these small mills and the grow of backlash over extedned periods of use.

This is the servo system I am considering using. I did not see this in the description, but does anyone know if it is closed or open loop? And has anyone had any experience with this company? I will be using mastercam 8 or 9. There might be another program I can get through my work, but the name of it ecapes me at the moment.

Also, those of you with similar setups, anythoughts on flood cooling? Any luck?

Thanks in advanced.
