Laser Surface Hardening Machines

Machine parts ranging from large to minute size can be hardened. The resulting hardness is governed primarily by the materials carbon content. Commonly hardened components include shafts, journals, guide rails and parting plane surfaces.

This machine is used to repair the mold parts using wire feeder. It is used in die cast industry,automobile industry,biomedical industry.

Surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material’s surface, forming a thin layer of a harder alloy. Selective hardening processes can be done by flame, induction, electron beams and laser beam. Flame hardening is widely used in deep hardening for large substrates. Induction hardening is suitable for small parts in production lines. Electron beam and laser beam hardening are sometimes not distinguished from in from those in hard facings or high-energy treatments. These processes are applicable only to steels that have sufficient carbon and alloy content to allow quench hardening. Diode laser can be used to harden the material in localized area, so that only the stress zones of a part can be harden.

Features:

• Highly defined energy deposition and hardness possibility to adjust its spot ideally to the center require hardening and therefore to achieve extremely high throughput
• Dry process know quench self cooling through thermal conduction crystal hardening structure controllable process contactless temperature measurement using pyromatry, no need for surface preparation as well as environmental compliance costs associated with emission and depositional of the chemical utilized in the painting process
• Low installation cost. High reliability, low maintaining cost
• Low operating cost, increased efficiency, selective hardening both is depth and location. Low or negligible distortion precision heating and control. Environmentally friendly very high process speed hardening of larger verity of space higher hardness, no post processing is required. Fatigue life of components treated improved, a chemically cleaned light source delivers precisely controlled energy to localized region
• Fiber optics beam delivery system and robot manipulation capabilities enable the process to be easily automated and provide remote axes to the component. Low heat input process gives precision control of geometry and composition of modified material

We have developed a Robotic & CNC type laser hardening work station which allows us to perform large scale projects and hardening of parts with mass over 12.5 tonnes on the customers premises.
