Hi
I was machining a ballscrew and the carriage was kicking up and down as the tool was cutting. After checking out
the machine I see that the saddle gib is loose. I could slide a credit card under the gib. To me it looks like the gib
is not adjustable for wear. I did a search online and its mentioned that tooling pressures are usually down so a loose
gib is not a issue. To my eye it seems like it is a issue. It seems in the case of cutting a ballscrew the helix places
a up and down force on the carriage.
I was going to add three setscrews with brass pins that would take up the clearance under the gib. Re-machining the
gib looked like a pain. Most of the surfaces are un-machined. Need some ideas for a fix.
Regards barry
