Laser quenching in cnc flame cutter is a relatively advanced repair method, which not only can restore the damaged parts to the outer dimensions, almost no deformation or less deformation, and no need to temper after quenching, the quenching hardness is higher than the conventional method. Laser quenching in cnc flame cutters has been widely used in aviation, petroleum, automotive, machinery manufacturing, shipbuilding, mold manufacturing and other industries.
Laser quenching in cnc flame cutter is also called laser phase transformation hardening, which belongs to the category of surface heat treatment. The laser quenching in the cnc flame cutter scans the surface of the workpiece by laser beam, so that the surface of the workpiece rapidly rises above the phase transition temperature and below the melting temperature, then stops or removes the laser beam. The heat is quickly transferred from the surface of the workpiece to the inside of the substrate, and the surface is rapidly cooled. The heat-receiving layer is rapidly cooled to below the martensite transformation point, thereby achieving phase transformation hardening of the workpiece.Laser quenching in cnc flame cutter has the following characteristics.
1.Cnc flame cutter heating is very fast and can be quenched by its own cooling. As long as the workpiece of the cnc flame cutter has sufficient mass, the cooling rate is also quite fast, so that ultra-fine grain structure can be obtained.
2.Cnc flame cutter has small internal stress and minimal distortion.
3.Cnc flame cutter has low surface roughness and does not require finishing.
4.Cnc flame cutter laser quenching can control the heating part very accurately, such as micropores, grooves, bottoms, corners and other parts of the quenching.
5.Can be cnc flame cutter surface alloying treatment.
6.Cnc flame cutter can accurately control the processing conditions, can realize on-line processing, and is easy to connect with the computer, which is convenient for automatic production.
