The invention relates to a metal sheet processing machine, which comprises a supporting seat, a driving device, a supporting device, a rolling device and a vibrating device. The driving device and the supporting device are arranged on the supporting seat. The rolling device is arranged on the supporting device, and comprises a first roll wheel device and a second roll wheel device. The vibrating device is connected to the second roll wheel device in order to be matched with a slide rail. Thus the first roll wheel device and the second roll wheel device are driven by the driving device to rotate in opposite directions, wherein, the second roll wheel device even performs reciprocating movement with linear swinging by means of the vibrating device. The metal sheet processing machine ensures that the stress strain inside a material is subject to compression strain between two roll wheels and is also imposed with shearing strain by the two roll wheels to increase the plastic deformation of the material.
