Abstract
A dust collector for a laser drilling machine is provided between a lens table and a workpiece to be processed and includes an upper inlet port and a lower inlet port arranged on one side of a space defined by four side walls, and an exhaust port arranged opposite the inlet ports. The total amount of air supplied from the two inlet ports is 30 to 70% of the exhaust rate. The lower inlet port has an air supply capacity 1.5 to 4.5 times that of the upper inlet port.
