Machine Introduction

What is laser hardening technology?

Laser hardening is a hardening technology that uses a laser to heat the surface of a material above the phase transition point. As the material itself cools, austenite transforms into martensite, thereby hardening the surface of the material.

 

Advantages

I. High and uniform hardness: After laser hardening, the surface hardness of the material is increased by 15% -20% compared to conventional hardening, and the hardness distribution is more uniform. For example, after laser hardening, the surface hardness of 45 steel can reach HRC55-62, while the hardness of conventional hardening is generally HRC40-50.
 

II. The heat-affected zone is small: the laser energy is concentrated, and the heating and cooling speed is extremely fast. The heat-affected zone is usually only a few tens of micrometers to several hundred micrometers, and the workpiece deformation is small, especially suitable for processing parts with high precision requirements. For example, laser hardening of precision gears can basically not affect their original accuracy.
 

III. The depth of the layer can be controlled accurately by adjusting parameters such as laser power, scanning speed, and light spot diameter. Generally, the depth of the layer is between 0.2-2mm.
 

V. High process flexibility: It can harden parts with complex shapes and local areas, and can also achieve selective hardening, such as hardening and strengthening the local wear parts of mold edges and shaft parts.
 

VI. Environmental protection and energy saving: Compared with traditional hardening methods (such as salt bath hardening), laser quenching does not require the use of a large amount of hardening medium, has no waste liquid discharge, and has a high energy utilization rate, which meets the requirements of environmental protection and energy saving.

 

Machine Applications

Laser hardening uses a high-energy density laser beam to scan the surface of the workpiece at an extremely fast speed. During this short period of time, the surface of the workpiece absorbs laser energy, and the temperature rapidly rises above the phase transition point and below the melting point of the material, causing the surface material to austenitize. When the laser beam is removed, due to the thermal conduction of the material matrix, the surface layer at high temperature undergoes self-cooling hardening at an extremely fast cooling rate, thereby transforming the surface structure into hardened structures such as martensite, achieving surface strengthening, and improving the hardness, wear resistance, corrosion resistance, and fatigue strength of the material surface.

1. High and uniform hardness: Compared with conventional hardening, the surface hardness of the material after laser hardening can be increased by 15% -20%, and the hardness distribution is more uniform. For example, after laser hardening of 45 steel, the surface hardness can reach HRC55-62, while the hardness of conventional hardening is generally HRC40-50.
    
2.

3. The depth of the quenched layer is controllable: By flexibly adjusting parameters such as laser power, scanning speed, and light spot diameter, the depth of the quenched layer can be accurately controlled. Generally, the depth of the quenched layer is between 0.2-2mm.

Machine Specifications

 

 

 For mold hardening, we generally recommend customers to use a 6000W laser hardening machine and a FANUC robot. The tooling equipment needs to be determined according to the customer's own needs.
