The advantages of laser cutting machine laser phase transformation strengthening

by：Transon 2020-10-28

Laser phase transformation strengthening the advantages of laser phase transformation strengthening laser cutting machine is mainly used in surface treatment, compared with other surface treatment, has the following characteristics: ( 1) High energy laser beam, the surface of the workpiece quick heating, cooling fast, martensite hardened layer is thinner, compared to the conventional quenching hardness high 15% 20%. ( 2) Only a small amount of metal workpiece surface for heating, less energy consumption, little deformation, deformation of workpiece, can save straightening and fine grinding process, such as local surface quenching for precision parts. ( 3) To the side of the inner hole or groove and the bottom of the quenched and complex partial quenching on the surface of the workpiece, and it is difficult to solve with other methods. ( 4) Because of the focused beam depth of focus is quite big, can allow a considerable roughness of workpiece surface, convenient for spline shaft, gear quenching. ( 5) Hardening depth and area can be precise control. ( 6) Laser quenching in addition to the thin pieces are usually can the cold hardening, quenching medium, such as oil, water, no pollution. ( 7) Because of its simple process, quenching time is short, quenching process can be arranged in a line.
