Abstract

The invention relates to a laser cutting method which mainly solves the problems in the prior art that when a laser cutting machine processes a pipe with a small diameter, the produced heat damages parts and chips are not easily removed. The laser wet cutting method comprises the following steps that the pipe to be cut is fixedly arranged on the rotary shaft of the cutting machine, a water guiding pipe of the water guiding system of the cutting machine is inserted from one end of the thin-wall pipe to be cut, the laser cutting machine is started so that the pipe to be cut rotates, the water guiding system of the laser cutting machine is started so that the water guiding pipe rotates, the water circulation module of the laser cutting machine is started, and the cutting head of the laser cutting machine is started to cut the pipe. Due to the adoption of the technical scheme, the problems are well solved, and the laser cutting method can be used in the industrial production of laser cutting machining.

Description

[0001] technical field [0002] The invention relates to a laser wet cutting processing method for thin-walled pipes, in particular to a laser wet cutting processing method with a pre-spray water guiding system. Background technique [0003] Laser cutting technology is widely used in the processing of metal and non-metal materials due to its advantages of reducing processing time, reducing processing costs and improving workpiece quality, and laser cutting processing is gradually replacing traditional cutting tools. [0004] Laser micromachining has become the main method for thin-walled pipe processing due to its high processing efficiency, less cutting residue, non-contact processing, and easy automation of the processing process. The laser cutting of thin-walled pipe is to move the overlapping laser pulse points along the cutting line on the pipe, and at the same time input high pressure oxygen to assist melting and cutting. The material at the laser focus point is melte...
