Claim:
A bidirectional cross airflow machine tool, comprising: a machine tool including a housing chamber to hold a tool spindle, the tool spindle being coupled with a balance weight member which includes a first balance weight portion and a second balance weight portion arranged in an up and down manner so that the tool spindle generates eccentric rotation against the machine tool, the machine tool also including air inlets and air outlets at two sides in an up and down fashion; and a radiator which is located on the balance weight member and rotates synchronously with the tool spindle including a first vane set located on the first balance weight portion and a second vane set located on the second balance weight portion, the first vane set sucking air via the air inlets at one side of the machine tool during rotation of the tool spindle, the air being conducted from the first vane set to the first balance weight portion and the second balance weight portion and then being discharged via the second vane set through the air outlets at another side of the machine tool to form cross cooling airflow.
