Spindle drive support

A workpiece processing machine comprising:

• a processing tool movable to engage a workpiece with a force applied along a tool drive axis;
• a force transmission member coupled to the processing tool and having two helical spindle drive threads spaced apart along the tool drive axis, through which drive threads tool forces are transmitted;
• and
• one or more drive motors operable to move the force transmission member by applying force through the spindle drive threads to displace the force transmission member and the tool along the tool drive axis,
• wherein the force transmission member is coupled to the two helical spindle drives so as to distribute the tool force between the two spindle drive threads, with each spindle drive thread bearing only a portion of the tool force.

A machine for processing workpieces, the machine comprising:

• a spindle drive having a first spindle drive unit and a second spindle drive unit;
• a force introduction element coupled to the first spindle drive unit and the second spindle drive unit;
• and
• a force transmission element configured to transmit a force associated with a processing tool to the force introduction element, wherein the force introduction element is configured to distribute the force between the first spindle drive unit and the second spindle drive unit.
