Ray, do you know anyone that might want a Bridge port mill? This is a ball screw machine that was a two axis CNC. All the old electronics were bad. It is a very good manual machine or can be retrofitted to be a Mach3 driven 2 axis CNC. I will sell without the drives , power supplies and motors (brand new) for what I paid which is $1800. Or with all the new electronics for $2300.

Ooooh Tool porn!
I love my little mill, that one probably weighs about 3000lbs, nice mill and good price. _________________ It's never too late to be a bad example. I spent all my money on Bikes, Broads, and Booze, the rest I wasted. |

Hi Scott..you want tool porn?
In my (very) small shop I can take pictures that ought to make you drool... BTW, very nice price on the Bridgeport. But aren't the ball screws hard to use manually? Cheers Erik _________________ Paused building - bought a "flying GoldWing" to learn on |

All I have ever used was a manual mill, I thought I was living large the first time I got to use a DRO!
(digital read out) I think Jake is on the totally manual thing too... I like cool tools, _________________ It's never too late to be a bad example. I spent all my money on Bikes, Broads, and Booze, the rest I wasted. |

Yes, they are used for CNC because they are slop-free.
But AFAIR, a ballscrew is much more coarse. (my mill is manual also) One revolution goes a longer way than on a manual mill. So it's harder to move the table than on a manual mill. Cheers Erik _________________ Paused building - bought a "flying GoldWing" to learn on |

They are only more coarse if you order them that way.
I just put ball screws on one of my Bridgeports. The new ball screws are 200 thousandths per revolution just like the oem lead screws rcflier wrote: Yes, they are used for CNC because they are slop-free. But AFAIR, a ballscrew is much more coarse.
