A machine tool is a mechanical equipment made to perform a use or other repetitive function, with an adapted power and precision. It is a production method made to hold a fixed, rotating or mobile machine, and to mark an action to it in order to deform or machine an assembly or a part held on a mobile or fixed table.
HISTORY
During the industrial revolution, the metal lathe played a leading role. Generally, the first machine tools were developed by French engineers in the 18th century. Some people saw the possibility of performing operations mechanically that the handicraft methods could not guarantee with determination. Others were motivated by the concern of a higher profit. The infinite expansion of machine making as well as the ever increasing precision are from this period an important theory of industrial machinismo. The thermal engines of cars, agricultural machines and trucks are the most astonishing examples of machines built in very great result and requires complex and numerous machinings.
TYPOLOGY
There are several types of machine tools, depending on their functions. First, there are the machine tools for the removal of substance as the mechanized saws also called debiteuses, the lathe, the milling machine, the grinding machine, the drill press, the vice fileurizer, and the transfer machine. And then there are the devices for assembly such as the screw machine. Otherwise, they can be classified into 2 main categories, one is conventional machine tool and the other is CNC machine tool or multi activity machining center. Often, a machine tool consists of a rigid frame designed with great determination, a table sliding along several axes, one or more figures equipped with spindle to ensure the tool, several motors and operating elements.
IMPORTANCE OF THE MACHINE TOOL
The machine tools play a vital role in the evolution of a country established in the heart of the industrial equipment. First, the economic importance justifies its attention. From the beginning of the nineteenth century, it gives birth to an industrial era or a machinismo era. It brings a social and economic change. The very high number of machine tool prospects develops the importance brought by it. Currently, the use of metals is massive in indefinite utilities of equipment and consumption. And then, in a political point of view, the machine tool is a key solution for a country that wants to increase its industry, since it constitutes a unique method to equip itself, realizing the least feasible calls abroad and to approve its singular technique. The machine tools are the work of an invention favored by the industrial development. The words sought by the customers with their traders are a suitable situation for the blossoming of the mechanical qualities, for a country, they are one of the industrial forces.
The standard machine remains the most practical in developing countries, as it is less expensive and instantly available.
