Every day we use the products of the labor of a machine operator, but, as a rule, we do not notice them. Imagine turning on your computer in the morning, sitting comfortably in your swivel chair at your desk at work, and picking up drawing tools or a pen. It would seem that there is no connection with the profession of a machine operator in such normal day there is no ordinary person. In fact, there is a connection, and it lies in the details of which a computer or a pen is made. And who does all these details? That's right, machinist!

In real life, we use the products of the labor of a machine operator every day, but, as a rule, we do not notice them. Imagine, in the morning you turned on your computer, left the house, got into a car or a trolleybus, at work you sat comfortably on a swivel chair at your desk and picked up drawing tools or a pen. There seems to be no connection with machinist profession in such an ordinary day there is no ordinary person. But it only seems at first glance. In fact, there is a connection, and it lies in the details of which the computer, and the trolleybus, and the table, and the pen are made. And who does all these details? That's right, machinist!

So we can safely say that the work of a machine operator is not only necessary, but literally irreplaceable. At the same time, the work of such a specialist is hidden by a veil of secrecy, since he grinds details, both miniature and gigantic in size, in a workshop where only a narrow circle of people have access. Yes and in periodicals, books or films, the specifics of the work of a machine operator are practically not disclosed. Therefore, most of us only approximately know what machine operators do and what are the features of this profession. We decided to correct the "state of things" and introduce you to this mysterious, but so important profession for the development of society.

Who is a machine operator?

A specialist who, using special machines, manufactures parts for various mechanisms from the most different materials(usually wood or metal). Since the work of this specialist combines the activities of other working professions (for example, a miller, turner, grinder, gear cutter, etc.), he is able to work for the most different machines(milling, grinding, turning, etc.).

The name of the profession goes back to the Indo-European word "stan", which means "what is worth". Thus, it directly reflects the main activity of the machine operator: working with stationary fixtures. different levels difficulties. In its usual form, this profession appeared relatively recently - in the 19th century, when Europe was going through the times of the industrial revolution, and production became mechanized. However, the first machinists can be considered primitive people who carved tools and protection from wood or bone. It was only in the 20th century that automated machines, and the profession of a machine operator received the official status of a working specialty. At the same time, it was divided into several narrow specializations, which depend on the material with which the specialist works:

• woodworking machine operator- mainly engaged in drilling holes for fixing furniture parts, processing on lathe details, makes blanks for veneer and sews boards into boards on woodworking machines. Everything that accompanies these processes is also the professional duty of a woodworking machine operator: the choice of material, its rejection, the development and reading of drawings, the laying of blanks and finished products;
• machine tool operator - includes four specializations: turner, miller, driller and grinder. This division is due not only to differences in production activities, but also with the capabilities of machine tools. For example, if a turner grinds parts, then a milling machine processes workpieces (including cutting cavities ranging in size from microns to several meters). In turn, the driller makes through holes of various sizes and cuts threads, and the grinder performs the final processing of the metal, working on a grinding machine with abrasive materials. In addition to the main professional duties for working with metal, all metalworking machine operators must develop and read drawings, select material and determine its quality, clean up after work workplace;
• wide profile machinist- knows the technological chain of manufacturing parts and is able to work on almost all machines and other equipment. Respectively, professional activity such a specialist includes the duties of both a woodworking master and a metalworking master.

With the advent of large and complex machines with program management appeared at the machine operator and one more specialization - the operator of CNC machines. Job Responsibilities such a specialist includes: conducting the material processing process from the control panel, maintenance of multi-purpose machines and manipulators for mechanical feeding of workpieces, adjustment of mechanisms in the process.

What personal qualities should a machinist have?

The profession of a machine operator cannot be called easy - the specialist is almost constantly on his feet, while always in suspense, since the processing of both wood and metal is physically hard work. Besides, work of a machinist involves the exact observance and compliance of the parts manufactured by him with the drawings. Therefore, a specialist must have such personal qualities, How:

Note that the machine operator is also an intellectual profession. Therefore, a specialist must be able to read drawings, know mathematics and physics, the basics of chemistry and materials science, in particular the properties of wood or metals, in order to determine the time, processing method, and also to cull low-quality material.

Benefits of being a machinist

IN modern world production various parts and machines is constantly increasing and becoming more complex, so specialists in their manufacture are not only in demand, but vital. And this is the main the advantage of being a machine operator. By the way, in our country the situation with machine operators has taken a catastrophic situation: the old generation, with extensive work experience, is retiring, and the new one, not only does not yet have sufficient practical skills, is also small in number.

The result of this situation is that in the struggle for highly qualified specialists, employers are ready to offer them a decent level of remuneration. If even some 5-10 years ago, machine operators received an obscenely small salary, today, if they have the appropriate qualifications, they can count on remuneration for their labor in the range of 40-60 thousand rubles.

Well, the most important thing. The profession of a machine operator is a pronounced male profession which leaves an indelible imprint on a person. That is why experienced machinists are convinced that this work will turn any shy young man into a strong and confident man.

Disadvantages of being a machinist

Disadvantages of being a machinist mainly associated with the need to constantly maintain good physical shape. In this case, the ability to maintain a high degree of concentration and an accurate eye is especially important. If a specialist is not able to withstand work-related physical stress, then it is better for him to leave the profession, since fatigue in the workplace can lead to an increased risk of injury, and possibly chronic depression.

In addition, the workplace of the machine operator is very difficult to call comfortable and, since the manufacture of parts involves a large amount of production waste (chips, dust, grease, etc.). Safety regulations require the machine operator to wear protective clothing at all times at work and protective equipment. And it doesn't matter if it's hot in the shop or not.

Finally, this profession is categorically not suitable for those who do not want or cannot constantly improve. After all technical progress does not stand still, and in order to keep pace with it, the machine operator has to grow professionally, regularly monitoring and studying the latest achievements of science and technology in the field of machine tool building.

Where can you get a job as a machinist?

Get a job as a machinist can be in any specialized college or technical school that provides training in such specialties as "Woodworking Technology" or "Metalworking Technology". Well, if we take into account the high need for such specialists, then we can say with confidence that such educational establishments available in every Russian city. At the same time, the choice of a technical school or college is not of particular importance, since the level of training of workers in Russia has always been, is and, we hope, will be quite high.
