Granitan® machine bed

STUDER has been manufacturing machine beds from its own specially developed Granitan® mineral casting for decades. In comparison with machine beds made from iron-based materials, Granitan® machine beds have a more favorable thermal and better cushioning behavior. Temporary temperature fluctuations are largely compensated by the favorable thermal behavior of Granitan®. The excellent cushioning behavior of the machine bed ensures outstanding surface quality of the ground workpieces. Far fewer energy and raw material resources are consumed in the manufacture of Granitan®, in comparison with the manufacturing process for steel.

Very intriguing. I hope I get to see one of these in person someday.

So is Granitan better than natural granite of the same size and thickness?

[@car9167]

Natural granite has 20-60GPa modulus of elasticity while polymer concrete depending on formula and additives 20-30GPa. But how would you manufacture the machine bed from a huge chunk of granite and what the cost of that would be?
