A cutting machine for sintered stones has a track base, a cutting device, and two clamping devices. The track base has at least one connecting portion and an anti-slip strip mounted in the at least one connecting portion. The cutting device is connected to the track base and has a cutter and two measuring seats. The cutter has a cutting wheel. The measuring seats are movably disposed on the track base respectively at two sides of the cutter, and each measuring seat has a positioning arm. The positioning arm has a reference board with an external side face. An imaginary extension line of the external side face of the reference board of each measuring seat aligns with a cutting edge of the cutting wheel. The clamping devices are connected to the track base, and each clamping device has a clamping mount and a pressing rod.
