Stone Calibrating Machine breaks through traditional designing concept of stone calibrating machine. It adopts double milling heads tocalibrate the surfaceof stones. And the stones are moved by the feeding belts. Two processing steps are finished at one time. Therefore, the calibrating efficiency improves two times and the calibrating effect of stones leaps seriously.
