Double-side or one-side machine tool

A machine tool comprising:

• a first support disk comprising a clamping surface;
• a first working disk fastened to the first support disk, wherein the first working disk comprises a clamping surface;
• a counter bearing element, wherein a working gap dimensioned to accept a flat workpiece is defined between the first working disk and the counter bearing element;
• a first clamping arrangement comprising a plurality of clamping screws configured to clamp the clamping surface of the first working disk to the clamping surface of the first support disk, wherein the clamping surface of the first working disk faces away from the working gap;
• and
• at least one decoupling element configured to reduce friction between the first support disk and the first working disk and enable thermally induced movement of the working disk from an original position relative to the support disk and a return of the working disk to the original position after the thermally induced movement, wherein the at least one decoupling element comprises:
• at least one bearing arranged between the clamping surface of the first working disk and the first support disk, wherein the at least one bearing comprises at least one rolling bearing, and
• a plurality of elastic spring washers, each spring washer of the plurality of elastic spring washers is positioned between a screw head of each of the plurality of clamping screws and a surface of the first support disk facing away from the first working disk, wherein each elastic spring washer of the plurality of elastic spring washers is configured to prestress the first clamping arrangement;
• wherein the first working disk and the counter bearing element are configured to be driven to rotate relative to each other by at least one drive shaft, and wherein the first working disk and the counter bearing element are configured to machine at least one side of the flat workpiece.
