Patent ID: 8333536

Claim:
A machining machine comprising: a base including a working room in which to move and rotate a tool and a workpiece; a working head including a driving spindle rotatably disposed on a lower end of the working head, for rotating the tool, and a lower end of the driving spindle clamping the tool; a carrier including a seat configured to move relative to the base in a vertical Z-axis direction, a rotary shaft, and a fixing holder, the seat being fixed on one side of the working room, the rotary shaft mounted on the seat so as to project laterally with respect to the Z-axis along an A-axis and the rotary shaft being configured to be driven relative to the seat to rotate about the A axis, the fixing holder being connected to an end portion of the rotary shaft so that the workpiece is fixed to the fixing holder; a lateral driving device disposed on the base and located on one side of the working room spaced in a horizontal direction from the carrier in order to drive the working head to move in an X axis and a Y axis that are orthogonal to the Z axis; a vertical driving device disposed on the base and located on a side of the working room spaced from the working head in a horizontal direction and configured to drive the seat to move in the Z axis direction; wherein the machining machine further includes a dust collecting mechanism disposed on a lower side thereof to collect chips produced from machining the workpiece with the tool, the dust collecting mechanism includes a groove, a tank, a suction device for collecting dust, and a switching device, wherein the groove is disposed below the working room, and is formed in a funnel shape to receive the chips falling from the working room, wherein the groove is in operative communication with a pipe that has a first outlet configured to route the chips to the tank and that has a second outlet configured to route the chips to the suction device, and wherein the switching device is operable to pivot relative to the pipe to selectively close the first outlet to route the chips to the suction device via the second outlet and to pivot relative to the pipe to alternatively selectively close the second outlet to route the chips to the tank via the first outlet.
