The equipment uses advanced lasers, industrial robots and control systems to form a multi-axis linkage automated laser processing system. Customized tooling and loading and unloading devices are developed according to the customer’s part shape and process requirements. It can realize automated laser quenching, automatic loading and unloading and other functions for workpieces.

Advantages of laser quenching process

The laser quenching process is a quenching technology that uses laser to heat the surface of the material to above the austenite phase transition point. As the material cools itself, the austenite is transformed into martensite, thereby hardening the surface of the material. Laser quenching has high power density, fast cooling speed, and does not require cooling media such as water or oil. Compared with induction quenching, flame quenching, and carburizing quenching processes, laser quenching has a uniform hardened layer, higher hardness, small workpiece deformation, easy control of the heating layer depth and heating trajectory, and is easy to automate. It does not need to design corresponding induction coils according to different part sizes like induction quenching, and the processing of large parts does not need to be limited by the furnace size during chemical heat treatment such as carburizing quenching. Therefore, in many industrial fields, laser quenching processes are gradually replacing traditional processes such as induction quenching and chemical heat treatment. It is especially important that the deformation of the workpiece before and after laser quenching can be almost ignored, which is particularly suitable for surface treatment of parts with high precision requirements.
