Machine tool and machine tool system

A machine tool system comprising:

• at least first and second machine tools, each of the first and second machine tools comprising:
• a respective right side and a respective left side,
• a base;
• a table installed on the base;
• a column having at least a front surface, a height extending in an up-down direction, and a width extending in a right-left direction;
• a main spindle proximate the front surface of the column, to which a tool is mounted, the main spindle being caused to approach a workpiece on the table along the up-down direction;
• and
• a trunnion unit including a cradle rotatably holding the table on which the workpiece is placed, the cradle having a rotation axis that extends in a front-rear direction, and the trunnion unit being linearly movable in the right-left direction;
• wherein the rotation axis intersects the front surface of the column, and
• wherein the right-left direction and the front-rear direction extend perpendicular to one another;
• wherein the trunnion unit of the first machine tool is linearly movable in the right-left direction between a right position proximate the right side thereof and a left position proximate the left side thereof, and the trunnion unit of the second machine tool is linearly movable in the right-left direction between a left position proximate the left side thereof and a right position proximate the right side thereof,
• wherein a sum of a first distance between the right position of the trunnion unit of the first machine tool and the right side of the first machine tool, plus a second distance between the left position of the trunnion unit of the second machine tool and the left side of the second machine tool, plus a third distance between the right side of the first machine tool and the left side of the second machine tool, is less than or equal to a fourth distance between the trunnion unit of the first machine tool in the right position and the trunnion unit of the second machine tool in the left position, and
• when the trunnion unit of the first machine tool is in the associated right position and when the trunnion unit of the second machine tool is in the associated left position, the workpiece is able to be handed off from one of the trunnion unit of the first machine tool and the trunnion unit of the second machine tool to the other one of the trunnion unit of the first machine tool and the trunnion unit of the second machine tool.
