THE TECHNOLOGY OF THE LASER BEAM CUTTING ON A CNC MACHINE

(STEF92 Technology, 2018-06-20, Lukáš Kudrna)

Show more

The technology of cutting with a laser beam today is a widespread solution for thermally cuttable materials. In mechanical engineering laser technologies currently, belong among the most progressive ways how a person can act on materials within the production process. Machining and processing materials using a laser is based on the conversion of light energy into heat energy. According to the active environment, a distinction can be made between three basic types of lasers - gas, solid state and semiconducting. Th...

THE TECHNOLOGY OF THE OXY-FUEL CUTTING ON A CNC MACHINE

(STEF92 Technology, 2018-06-20, Lukáš Kudrna)

Show more

The technology of oxy-cutting is a widespread solution for thermally cuttable materials nowadays. This article discusses the use of oxy-cutting technology on CNC machines. This technology is particularly suitable for unalloyed and low-alloy steels and cast steels. With the help of this technology, it is possible to cut sheets ranging from 3 to 1000 mm. For sheets with a thickness of 20 mm it is preferable to use a laser or plasma technology. When cutting with an oxy-fuel the workpiece it is initially heated on the...

THE TECHNOLOGY OF THE PLASMA CUTTING ON A CNC MACHINE

(STEF92 Technology, 2017-06-20, Lukas Kudrna, Jiri Fries)

Show more

The technology of cutting with a plasma arc is today a very advanced solution for thermally cuttable conductive materials. Plasma or also the plasma arc is composed of positively and negatively charged particles, excited and neutral atoms and molecules. As it contains free particles, it is electrically conductive and thus subject to the effects of an electric and magnetic field. This article discusses the use of plasma cutting technology on a CNC machine. The resulting quality of the plasma cutting is determined b...
