I recently picked up this little Tupperware VF0 from a friends shop that was moving.

Serial number is in the 1800’s, very early machine.

Everything works after a couple adjustments and cleaning.
7k spindle, rigid tap etc.

This is mainly for my personal use. I have run haas machines for about 20years.

Ran my first real part and found issues with my “y” axis.

I interpolated a 7.13in diameter hole in a piece of aluminum.

“X” was dead on 7.13 but “Y” measure 7.148. Approx .018 large.

I still need to do a backlash test, and recently found that this machine has belt driven ball screws.

Could this be from stretch?

Thank you
Ken
