What are the characteristics of laser quenching?

1, the laser quenching thermal cycle process of quenched parts is fast, medium carbon steel, large shaft.

2. Hardly damage the surface roughness, and use thin coating with oxidation protection, die steel and various dies.

3, laser quenching does not crack, accurate quantitative numerical control quenching, cold working die steel, mold, tool.

4, local, groove, groove quenching, precise positioning of CNC quenching, medium carbon alloy steel, shock absorber.

5. Laser quenching is clean and efficient, and does not need cooling media such as water or oil, cast iron materials and engine cylinders.

6. The quenching hardness is higher than the conventional method, and the quenching layer has fine structure and good strength and toughness, and the material is high-carbon alloy steel and large rolls.

7. Laser quenching is rapid heating and self-excited cooling, without furnace insulation and cooling liquid quenching. It is a pollution-free and environment-friendly heat treatment process, which is easy to uniformly quench the surface of large molds.

8. Because of the fast laser heating speed, small heat affected zone and surface scanning heating quenching, that is, instantaneous local heating quenching, the deformation of the treated mold is very small.

9. Because the divergence angle of the laser beam is very small and has good directivity, the die surface can be locally quenched accurately through the light guide system.

10, and the depth of laser surface hardening layer is generally 0.3 ~1.5 mm.
