The invention discloses a machine tool structure for weakening machine tool chatter. A lathe bed is sequentially provided with a first marble layer, a first elastic layer, a second marble layer, a second elastic layer and a third marble layer from top to bottom. The first marble layer, the second marble layer and the third marble layer are all made of artificial marble. The first elastic layer andthe second elastic layer are both made of viscoelastic damping materials. According to the machine tool structure, the manner and thickness of the viscoelastic materials implanted in the lathe bed ofa machine tool are obtained through analysis and calculation, and therefore the adverse effects caused by the chatter of the lathe bed of the machine tool are weakened to the greatest extent.
