The invention provides an automatic
cutting,
grinding and
polishing machine for a PCB. The automatic
cutting,
grinding and
polishing machine comprises a
machine body, a working region, a clamping jaw, an action executing unit and a control panel, wherein the machine body is provided with a horizontal plane and a
vertical plane which is perpendicular to the horizontal plane and is positioned at one side of the horizontal plane; the working region is arranged on the horizontal plane, and comprises a
polishing disc, a
grinding disc, a
cutting disc and a
laser aligning device; the action executing unit is arranged on the
vertical plane, and the clamping jaw is connected with the action executing unit and is driven by the action executing unit to move in the
vertical plane; and the control panel is arranged on the machine body and is positioned at one side of the working region. The automatic cutting, grinding and polishing machine for the PCB provided by the invention can realize advanced determining as well as automatic continuous cutting, grinding and polishing treatment of the PCB, is accurate in cutting position, is high in
processing efficiency, is good in continuity, and sufficiently meets the needs, on product structure checking, of a laboratory of the PCB.
