ML35-0XX-LD125.250 fiber laser cutting machine with linear motor positioning gantry stage

New series of fiber laser cutting machines with linear motor-driven positioning stage of own manufacture was launched in 2007. The series comprises the latest achievements of laser engineering and the 20-year experience of its manufacturer Lasers and Apparatus TM Scientific and Production Centre in the field of design, production and maintenance of hundreds of laser systems used by Russian companies of different profiles.

APPLICATION AND GENERAL INFORMATION

General information:

A workpiece or a sheet of material is fixed on a stationary workpiece stage or on a special quick-fixing arrangement in the machine work zone. The gantry moves by means of two linear synchronous motors along the Y axis over the metal sheet or the workpiece. Linear X-axis drive of the gantry moves the carriage with the Z-axis drive and the optical cutting head along the X axis. Stepper motor Z positioning stage equipped with an optical collimator moves along the Z axis. Standard size of the positioning stage 1250x2500x100. Laser machines are available with positioning stages of different sizes - 1250mm 850mm 100mm, 1250mm 1250mm 100mm, 1250mm 1500mm 100mm, 1500mm 3000mm 100mm and others. The use of linear synchronous motor drives and fiber lasers enables to considerably increase the machine reliability, to improve technical capabilities and production capacity and to achieve higher quality of machining.

The standard package includes Ytterbium fiber lasers manufactured by IPG with the output power of 0.7, 1.0, 1.5 and 2.0 kW. The control system allows to modulate the laser radiation power. Laser output power, pulse repetition rate and duration have a wide adjustment range, which allows to choose an appropriate mode of operation and achieve higher quality of machining.

Capacitance sensor and a microprocessor-based visual monitoring system of the cutting head provide automatic regulation of the clearance between the protective nozzle of the cutter and the workpiece during the cut.

The machine has an automatic supply system of air, oxygen and assist and protective gases to the work zone, which protects the focusing optics and improves the speed and quality of cutting.

ML35-0X0-LD machines have:

  • Components from the worlds leading suppliers: IPG (fiber lasers), AEROTECH (CNC-controllers); HIWIN (ball-bearing guides); RENISUAW (contactless encoders); CAMOZZI (pneumatic system components); IGUS (cable-carriers)
  • Patented linear motors of own manufacture
  • Design solutions that suit ergonomic requirements, offer extra functions through the use of options and modernization of the machine modules, ensure excellent durability and minimum maintenance service and have other advantage
