Development of energy, nuclear, engineering, petrochemical and chemical industry requires very massive and large workpieces. Requirements for machining workpieces of these department is the necessary adapt to the design and construction of machine tools. Analyses were conducted to carry out the overhaul and modernization for heavy cutting machine SKODA W 200 HC with digital subtraction, turntable S 100 C from 0 to 360пїЅ, while the carrying capacity of the turntable 100 t. The complexity of the repairs consisted o...

The aim of this article is to describe the possibility of increasing the service life of the rod eye on a tilting platform that is used to tilt heavy barrels between the two differences in heights in transport lines. This mode of transport was selected for the lack of space in a given area of a production line, which does not allow the implementation of an inclined plane, which would be structurally easier. Rotating those barrels by 90пїЅ that is achieved during this way of transport, is desired for subsequent tec...

When building the foundations of a machine tool, demands must be placed on high quality and, above all, on their stability during their entire lifetime. In practice, however, it shows that these requirements are not always fully met on the customerпїЅs side when laying foundations. In the course of working, these foundations are subsequently damaged and their uneven decline occurs, which results in a change of the machine alignment, and thus it also influences the accuracy of production. For the supplier of the ma...

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...
