Laser beam machine comprising a burr removal device

摘要

The invention provides a laser beam machine comprising a burr removal apparatus, which removes burrs (Wb) formed on the top surface of a workpiece (W). When pilot holes (PH) are produced in a workpiece (W) by a laser machining tool (60), molten particles scatter to form whisker-like burrs (Wb) on the top surface of the workpiece (W). A whisker-like burr removal apparatus (700) has a machining head (710) which is raised and lowered by a cylinder (720). It removes the whisker-like burrs (Wb) with a machining tool (730).
