The device for laser treating can be used for a shaped cutting of different materials, and also welding and heat treatment. The device includes the technological laser, beam transmitting system, control system, protective cabin, technological table for a sheet and rotary block, guiding beam from the laser to a workpeace. Distinctive feature of device is the moving block, located above a treated sheet, having a moving in horizontal plane drive, while the drive actuating mechanisms can have or no have contact with a treated sheet. The composition of moving block includes also technological lens with a rotary mirror, which is tied with a mirror of the rotary blockkinematically or optically, or with the help of own mirror electric drives. The security of moving block with power and process gases can be manufactured independently or with the help of a communications input unit . The given construction of device allows to eliminate mechanical devices of a drive, heavy moving blocks and, therefore, to simplify and lower the price, simultaneously to increase dynamic characteristics.
