Testing procedures for used machinery

[skyline]

I am contemplating about buying an old VMC for short production and prototype work. What procedures should I run the machine through to make sure I don't buy a lemon?

Here is a checklist I use during the initial inspection. Hope it helps.

Good Luck,

Thanks that was helpful. However, how do one check the to make sure the machine mech/electronics is in good running condition? Good alignment of the ways. Alignment of the spindle/runout and such. What is a good procedure to run the machine through it's paces and that it meets the specs stated? In terms of accuracy and such.
