The test done that way is a fake. Steel has a higher thermal conductivity, so the heat spreads faster. The two materials should be compared at the same final temperature. Then we see that the metal column has a welded lid, which means that it is empty. In practice, the thermal capacity is several times lower than that of the entire block of granite, accentuating the phenomenon of thermal expansion.
ok u got me,i sub.now i got some question.im considering building mineral casting cylindrical grinder and im interested in STUDER desighn.im wondering what drives x axis-hydrolic or ball screw?and what materil are the guide ways?
The question is what was the heating temperature? If your heat is high enough to reach the Tg of the epoxy, what will be the effect on the machine. Will the frame completely drop in its rigidity? Some machining work required to solder/braze/weld while the workpiece is still fastened to the machine to maintain the reference.

No,the rigidity will not drop.
