However, as machine sizes continue to grow, Hardinge finds that using Harcrete bases for bigger machines makes them too heavy, Don Thomason, an application engineer at Hardinge, said. So, for its larger size machines, Hardinge developed a base design that has reduced weight, yet with the same levels of rigidity and dampening qualities as a Harcrete base.

@DaBit said in Making an epoxy granite machine base: I used epoxy concrete to cast the gantry of my CNC machine. Idea was to cast on a flat surface so I had a fairly accurate plane to mount the linear rails. Did not work out that way, but hence the epoxy concrete. I did one thing different from the standard processing: I used very little epoxy.

06-09-2020· Machine bases made of epoxy granite most often exhibit outstanding working qualities, which often far exceed those of traditional materials. For example, the material features internal damping characteristics up to ten times better than that of cast iron, three times better than natural granite and almost 30 times better than steel.
