Abstract
A sand-belt finishing machine having a reciprocal movement mechanism includes a main body, a swingable support rack, a finishing device, and an eccentric device. Thus, the eccentric unit of the eccentric device produces a driving force to pull and push the first roller of the finishing device, so that the first roller is oscillated successively and produces a vibration or shock force on the sand belt of the finishing device, so as to remove and clear the powder chips attached on the surface of the sand belt.
