CUTTING METHOD FOR SYNTHETIC RESIN

摘要

PURPOSE:To cut synthetic resin instantly with the irradiation of the YAG laser beam having a specific wavelength by mixing the carbon black of a specified quantity in the synthetic resins material and irradiating said laser beam. CONSTITUTION:The synthetic resin material W to be cut is incorporated with 0.1-0.5wt% of carbon black Wa being a medium for absorbing the 1.06mum YAG laser beam. When the 1.06mum YAG laser beam Me is irradiated from a irradiation nozzle 5 on the synthetic resin work, auxiliary gas G is fed to a clearance 7a of a cylindrical material 7 and allowed to blow downward to seal the YAG laser Me as well as blow away molten synthetic resin downward.
