A research institute from Novosibirsk has developed an automated laser beam machine for material cutting, welding, heat treatment and laser-powder surfacing. The laser beam machine has a special self-filtered resonator achieving high quality radiation at power up to 10 kW. The machine can operate at technical purity gases and the CO2 – Air mixture (without N2 и He). The authors are interested in technical cooperation, commercial agreements with technical assistance or license agreements.
The automated laser beam machine consists of a laser with power of 1,5 – 5,0 kW, a portal type technological table with an operational field varying from 1,5 m x 2 m to 2,5 m x 6 m and an automated control and power unit. The machine allows performing the following operations: 1) Laser cutting metallic sheets, wood, plastics, paronite, glass, ceramics and other materials; 2) Laser welding metallic parts; 3) Laser heat treatment for manufacturing self-sharpening tools, hardening cylinder barrels of engines and restoration of worn mill roller surfaces (in combination with mechanical processing); 4) Laser-powder surfacing for manufacturing cutting tools with highly solid cutting surfaces.
