Laser Surface Hardening System

1. Lamp pump large energy electro-optical Q-switched laser 
2. Laser shock peening control system 
3, Six-axis automatic robot 
4, Special light guide arm and flexible optical path system

The Hercules serial lamp high energy electro-optic Q-switched laser is a high beam quality, high energy laser with high stability, high energy and high conversion efficiency.

Good applicability 
1. Suitable for surface strengthening of various metal materials 
LSP uses high power density laser to act on the surface layer of metal material, induces plastic deformation and grain refinement, and forms deep residual compressive stress. It is suitable for various metal materials (Cr/Ni/Ti/Al alloy, stainless steel, etc.). Surface strengthening.

2. The surface roughness has less influence 
After the LSP treatment, the micro-pits on the surface of the material are micron-scale, which is smoother than the traditional shot peening surface (the special process requires the mold LSP to be finely ground).

3. No heat effect on the workpiece 
LSP uses the "mechanical effect" of laser shock wave to modify the surface of the material to improve the fatigue resistance of the material. The processing process has no thermal influence on the workpiece.

Better effect 
1. The residual compressive stress layer is deeper 
The residual compressive stress has a depth of more than 1 mm (the residual stress of individual materials reaches 2 mm), which is 5-10 times that of conventional surface strengthening.

2. The residual compressive stress value is higher 
Taking typical materials as an example, the maximum residual compressive stress values of titanium alloy, stainless steel and superalloy after LSP treatment exceed 600,800,800 MPa respectively. 
3. The microstructure of the material is more compact and stable. 
LSP causes high-density dislocations and grain refinement, and has good stability under certain high temperature conditions, which can significantly improve the fatigue performance of the material.

Strong controllability 
LSPs can handle parts/parts that are difficult to handle in traditional processes by precisely controlling laser parameters and process parameters. 
1. Laser parameters are controllable 
The laser power density, spot, pulse width and other parameters can be precisely controlled. 
2. Process parameters are controllable 
It can accurately control the parameters such as the LSP's enhanced path, number of times, spot lap rate, and impact mode.

3. Complex parts/site reinforcement 
The LSP strengthening treatment can be performed on the ultra-thin members, the small hole side, the blade teeth, the leaf groove, the gear portion, and the like.
