Abstract:
1. A machining machine comprising: a base; a carrier including a seat, a rotary shaft, and a fixing holder, the seat being configured to move relative to the base in a Z axis direction, the rotary shaft being fixed on the seat so as to project from the seat laterally with respect to the Z-axis along an A-axis, and the rotary shaft driving the fixing holder to rotate about the A-axis, the fixing holder being coupled to an end portion of the rotary shaft to fix a workpiece on the fixing holder for rotation with the rotary shaft; a tool changing mechanism including a mount and a monitor, the mount being mounted to the rotary shaft so as to rotate with the rotary shaft, and the mount including a plurality of slots to each receive a respective tool, the monitor being fixed on the seat to measure a length of the tool clamped on a tool driving spindle; a working head moving above the carrier and the tool changing mechanism, the working head configured to move along X and Y axes that extend orthogonally to the Z axis and each other, and the working head including the tool driving spindle mounted on a lower end thereof to rotate a tool about an axis in order to machine a workpiece mounted on the fixing holder, and the lower end of the driving spindle configured to engage and disengage one of the tools of the tool changing mechanism to exchange a tool between the tool driving spindle and the mount.
