A heat dissipating architecture for a machine tool is provided. The machine tool includes an accommodating space, a tool shaft mounted in the accommodating space, a counter balancing mass having a first balancing portion and a second balancing portion mounted on the tool shaft for causing an eccentric rotation stroke of the tool shaft, and an inlet communicating with the accommodating space. The heat sink is mounted on the counter balancing mass. The heat sink includes a first blade portion corresponding to the first balancing portion, a second blade portion corresponding to the second balancing portion, and a linking portion for connecting the first and second blade portions, such that during the rotation stroke of the tool shaft, the heat sink inhales air via the inlet, transmit the air from the first blade portion to the second blade portion, and then exhausts the air from the second blade portion.
