You are right that it is fairly big and heavy. From another site: Swing over bed: 14" Swing over carriage: 8" Between centers: 12" Collet size: 16C Spindle bore: 1-5/8" HP: 7 Dims: 100" x 66" x 84" Weight: 5500 lbs It would NOT need ballscrews. It was built from the ground up to be a CNC machine, and already has ballscrews, motors, encoders (or maybe resolvers), etc. The only way it would need ballscrews was if it was used hard and is clapped out. And in that case, run away, don't plan on repairing it. Screws for that class of machine are NOT cheap. And if the screws are worn out then the ways and spindle bearings are also probably worn.
