An ice shaving machine includes a base, a main body mounted on the base and having a platform provided with a shaving blade, a limit module mounted on the platform, and a rotation disk mounted in the main body. The limit module has an inner periphery provided with a receiving space. Thus, the ice block is limited by the limit module so that the ice block will not produce vibration during rotation to keep the stability and safety of the ice shaving machine during operation. In addition, the limit module has a central point the same as that of the platform so that when the ice block is received in the receiving space of the limit module and is shaved by the shaving blade, the force from the ice block is distributed evenly and smoothly on the shaving blade.
