The expression “machine-tool” contains the definition in itself: a material intended to make the tool move by a transmission actuated by means of a motor. Instead of letting it be handled by the hand of the worker, the tool works itself through commands.
The possibilities of the worker, in possession of such a machine, are multiplied in a considerable way: his power is no longer limited to one-tenth of a horsepower, and the machine can operate continuously.
However, in the etymological sense, the word “machine-tool” means the mechanisms allowing to work with the most varied materials such as metals, wood, stone, leather, rubber, textile fibers, etc. Also, a machine tool is supposed to assemble, format and cut parts of these materials such as metalworking machinery do. In addition, they can also extract these materials from the ground in mines, quarries, etc.
The Origins of the Machine Tool
The history of the machine tool is intimately linked to the replacement of man by the machine for the execution of various tasks. By a persevering journey, that of technical progress, the machine has increasingly helped man, at the same rate of his efficiency and his power of action, while reducing his fatigue and his pain.
Importance of the Machine Tool
Located at the heart of industrial equipment, machine tools play a fundamental role in the development of a country. The economic importance justifies the attention paid to it by the production of the steam engine. The machine tool gave birth to the era of machinery, and the industrial era, from the beginning of the 19th century. It brought an unprecedented economic and social revolution by replacing teamwork, collective work, that of the craftsman, solitary and prime contractor.
The Tasks to be Accomplished By the Machine Tool
As mentioned above, the machines considered here are exclusively those intended for metalworking. These machines produce the desired parts, from the raw metal, either by removing material or by deformation. On the other hand, these parts fall into two main categories
- The parts of revolution, which are the most numerous
- The parallelepiped parts
The machines used for the machining of parts of revolution are essentially lathes, on which the work is carried out by cutting tools, and cylindrical grinding machines, on which the removal of material is carried out by abrasion by means of grinding wheels.
However, for parallelepipedic parts, milling machines, planers, boring machines, and drills are also used, which use cutting tools, and flat grinding machines equipped with grinding wheels.
Other categories of parts and works correspond to other types of machines.
Besides, to get Used Metalworking Machinery to utilize for your industrial needs, you must research properly to get all the features you want in it. Ensure that if you’re buying it from an online portal, you must meet the seller to observe their confidence in their product as well as to examine the product or machinery yourself.
