more B/S was Re: Ball screws

Hi,

Forgot to add that repeatability costs MUCH less than ACCURACY and is
quite good with rolled screws on this class of machine. If you get
parts that TRULY need better accuracy, you can "modify" the CNC
toolpath to get it, in most or many cases... Here you will be helped
by a good CAM s/w, so again it is a tradeoff and a choice needs to be
made if funds are limited. There's a lot of ways to climb a mountain.

P.S. Be sure you know the difference between resolution,
repeatability, and accuracy. And also that you understand how truly
ELUSIVE real ACCURACY is!
