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. Attachment: b1.jpg Attachment: b2.jpg Attachment: b3.jpg |

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 |

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, |

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 |

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.
