とするレーザ加工ヘツド。 In the laser processing head, the assist gas is supplied to a high pressure chamber formed between the exit surface side of the lens and the nozzle at the tip, and the laser beam focused by the lens and the assist gas are emitted from the nozzle. A pressure sensor is provided at a position in contact with the lens to measure the pressure applied to the lens due to the gas pressure in the high pressure chamber, and when the measured value of this pressure sensor exceeds a predetermined value, the supply of assist gas to the high pressure chamber is stopped. A laser processing head characterized in that it is equipped with a supply stop means for stopping the supply.
