After cleaning and degreasing my new mill I made some measurements to test X and Y axis using simple tools:
an indicator (metric 0,01mm/div)
an extension about 12,5 cm (5”) and
a small mirror to read the indicator when rotates and faces the mill column.
The procedure is quite simple. Place a surface plate on the mill table, put indicator in a collet (or in the drill chuck), zero it to a corner and then rotate it a full circle BY HAND writing down each corner reading.
To manage this procedure without a surface plate I used a piece of glass from an old scanner (as the flattest think in possession).
I found mill column to lean 0,2mm to the front and 0,4 mm to the left so I decided to shim the column.
Initial efforts using paper (0,06 mm thickness) failed miserably, so I looked for better and more robust shims.
Most convenient of all available materials was beer tin (nasty habits, I know) at a thickness 0,1 mm and kitchen aluminum foil at a thickness of 0,01mm.
After several trial and error settings I managed to make table stand vertical and the best readings I had were:
X axis 0,01 mm end to end
Y axis 0,02 mm end to end.
I’m quite happy with that and I can start use the mill now.
