Vertically movable tool magazine system

A vertically movable tool magazine system disposed on a machine tool having a worktable and at least one spindle, the vertically movable tool magazine system comprising:

• a vertically movable tool storage device comprising a vertical movement unit movable along a Y-axis, the vertical movement unit having a plurality of tool holder seats arranged from top to bottom thereof, each of the tool holder seats having at least one tool, each of the tool holder seats being switchable between a plurality of tool storage positions and a tool holder seat changing position by being lifted and lowered through the vertical movement unit;
• and
• a tool changing device configured to release the tool holder seat located at the tool holder seat changing position and drive the tool holder seat to be moved from the tool holder seat changing position to a tool changing position along at least one of an X-axis and a Z-axis, thereby allowing the spindle to remove or return the tool from or to the tool holder seat, or to return the tool holder seat to the vertical movement unit at the tool holder seat changing position along at least one of the X-axis and the Z-axis, thereby allowing the tool holder seat to resume moving between the plurality of tool storage positions along a Y-axis.
