A method and apparatus for processing a slotted sleeve. The processing method includes the following steps: spiral slot ablation, where a laser head emits laser light radially from a cylindrical rod to ablate it; the laser head moves parallel to the axial direction of the cylindrical rod, which rotates around its central axis, and the laser ablates a spiral slot on the outer circumferential surface of the rod; slag blowing, where a nozzle of an air blowing device approaches the spiral slot and blows air onto the laser-ablated area within the slot, blowing the slag generated during laser ablation out of the spiral slot. The nozzle can move with the laser head. The nozzle of this air blowing device can blow the slag generated during the laser ablation process out of the spiral slot, allowing for a deep and unobstructed spiral slot. Furthermore, laser processing of deep slots eliminates the need to consider the strength of the cutting tool, resulting in high processing efficiency. Four nozzles can be moved back and forth, ensuring that slag is not blown into other nozzles when one nozzle blows air.
