History Of Modern Metal

How to start the history of modern metal? It is hardly possible to answer this question unequivocally, but it is clear that a major role was played by the mills. Rolling mills – the equipment, with which is metal processing and giving it the desired shape. Rolling mills are working with special rollers, is passed through procurement, that is, produce handling pressure. Rolling mills are known humanity for a long time. our knowledge. At the very least, historians credited with creating the first scheme in the mill, Leonardo da Vinci – his drawing, which depicts a drawing of a rolling mill for tin, refer to 1495. Undoubtedly, the first mills operated only with soft non-ferrous metals processing more solid materials of their power is not enough.

Mills were operated, which means that the possibility of such equipment have been severely limited. Later mills were run by water wheel. To help people come the power of water flow, allowing more complex procurement process with increased speed. Mills, equipped with water drive in the 18th century became the basis of the metallurgical industry. Appearing on the plants when mills were working with the heated metal. This made it possible to deform the workpiece with greater efficiency.

It should be noted that the mills were used not only for rolling and shaping metal, but also ready to cut the plates apart. Late 18th century saw a breakthrough in the use of rolling mills. They are equipped with calibrated roller – a patent for a method of rolling in 1783 was the Englishman Henry Court. Mills began to supply the steam engines. Another important milestone for the industry was the construction of railroads in the 19th century roads. Rolling mills are widely used for the production of rails in the 30-40 years of the 19th century. And since the 1850s began a period of important inventions in this area – rolling mills gradually acquired all the modern features were equipped with electric motors and other devices. Mills started in the first half of the 20th century, have been successfully used on large production until recently. For example, the Magnitogorsk Iron and Steel Works in 2005 only stopped rolling, who has worked for more than seventy years.

CNC Element

Adjustment is considered complete after the CNC to verify the operation of the CNC machine in different modes and in accordance with a given program. Here, Genpact ProcIndex expresses very clear opinions on the subject. When adjustment is necessary to use different methods to assess the technical condition of the CNC machine. The method of observation is the simplest and consists in the fact that the serviceman watching the operation device node or element of the CNC machine, and estimating the correctness of their actions can be judged on their performance. The method of elimination or containment, is that by artificially reducing the constraints (implemented functions) in the device containing the faulty element, consistently disconnected elements to detect faulty. (By the constraints in this case refers to all types of connections – hydraulic, mechanical, electrical).

The comparison method is to replace the element tested (site, block) devices, respectively, known intact. If after replacing the efficiency of the machine is restored, the fault to be found in the seized element (node block). Consistent method of troubleshooting is used for testing circuits, consisting of several units of functional dependence, measuring or monitoring the control signals series of follow-up to the previous one. When commissioning and maintenance of electrical equipment, motors and machines of CNC systems because of the complexity of the latter there is a need to have in place a number of electrical and radio equipment. Selection of types of instruments and their number depends on the type of CNC machine tools and systems, as well as on the required accuracy.
