Laser processing head


Modular design, powder supply nozzle with integrated optical components, for external coating and versatile design suitable for various applications

Designed for reliable and stable processing in high-power EHLA and LMD processes

The integrated cooling and gas channels can improve efficiency and process control, suitable for precise powder feeding of various powder materials, including iron, nickel, cobalt-based, ceramics, etc., using ACunity powder feeders.

The modular design of the cladding nozzle is easy to replace, suitable for different application scenarios, and has a flexible range of spot sizes - it can adapt to various spot sizes and compatibility with various laser sources.


Laser quenching head


Quenching quality is uniform and controllable: Laser phase change hardening usually has a hardness 5 to 20% higher than conventional phase change hardening, and can obtain extremely fine hardened layer structure. Using high-power lasers, the depth of the hardening layer can reach 2mm.

Small processing deformation: Due to the fast laser heating speed, the heat affected zone is small, and the stress and deformation of phase transformation hardening are small.

Quenching area optional: It can be used to harden parts with complex shapes and parts that cannot be processed by other conventional methods, such as parts with grooves.

High degree of automation: The process is easy to achieve computer control and has a high degree of automation, which can be incorporated into the production line.

Inner Laser Cladding System

Inner Laser Cladding System

ACunity's newly launched inner cladding processing system boasts high integration, precision, and adaptability. It facilitates efficient and high-quality laser processing of the inner surfaces of various types of parts, achieving accessibility that traditional optical heads cannot. The system allows multiple processing applications such as internal hole cladding, repair, hardening, welding, and additive manufacturing. Depending on application requirements, different types of sensing systems can be equipped to ensure the stability of processing quality and enable real-time monitoring during the manufacturing process. Additionally, we customize special specifications of inner wall processing equipment for clients, which, when combined with ultra-high-speed laser cladding technology, can simultaneously process the inner and outer walls of products like hydraulic cylinders and columns.

By replacing the front nozzle, it can meet the processing requirements of laser cladding, repair, welding, hardening and quenching of different parts' inner walls and cavities. Due to limited visibility during the inner hole machining process, the machining head can be optionally equipped with a visual sensing and lighting system.
