Have you ever wondered how this miracle technology works? The proper operation and safety of the automatic design equipment is ensured by every detail that is included in its package: bolts, nuts, bushings, couplings, etc. All these components are the result of the hard work of a human turner, from labor activity on which scientific and technological progress as a whole depends.
Profession turner
A lathe is a specialist who is engaged in mechanical processing of parts from a variety of hard materials (metal, plastic, wood, etc.) through mastering the skills of working on a lathe.
The word “turner” itself has Proto-Slavic roots and in translation means “to sharpen”, “turning”. If you look at it, the beginnings of this profession appeared in ancient times, when people realized that the necessary part could be made from any material.
A turning specialist works on machines, which, depending on the type of material used, can be metalworking or woodworking.
Based on the fact that lathes are different types, and the work that can be performed on them is different, there are several specializations:
- carousel turner;
- head turner;
- revolver turner;
- turner-sharpener;
- lathe-borer;
- turner-miller;
- universal turner
It is worth noting that the responsibilities of a turner include not only working on machines, but also with workpieces, selecting the best ones and rejecting them, preparing the workplace and cleaning it after completion of the labor process.
The carousel turner is
The mechanical engineering industry cannot imagine its existence without such a specialist as a rotary turner. He specializes in the manufacture of cylindrical and cone-shaped objects, on the surface of which there are various holes, grooves, and one or another type of thread. Such a specialist works on a rotary machine operating on high voltage. The unit contains metal parts that are hot and rotate quickly. Therefore, special attention is given to compliance with safety regulations.
Operating principle: part processing is carried out through the interaction of a rotating workpiece and cutting tools, which move at a given speed and at an appropriate angle.
A carousel turner is a specialist whose responsibilities include:
- processing of complex workpieces using specialized equipment;
- grinding with a high degree of precision;
- boring holes;
- turning surfaces shaped like a cylinder or cone using several cutting tools;
- cutting various types of threads;
- processing of workpieces by plasma-mechanical method;
- processing of solid-type rolled wheels according to clearly established dimensions after running in.

Front turner - who is he? Such a specialist works on turning machine tools. The responsibilities of the windshield mechanic include processing of bodies and semi-finished parts. Heat-resistant stainless steel is used in the work). Such specialists are indispensable in aviation production.
Revolver turner
A turret lathe operator is a worker who maintains turret lathes and specializes in processing parts of varying levels of complexity depending on the level of professionalism. Processing involves the use of cutting tools and various devices.
What does a revolver do? He cuts the outer and internal thread various shapes(two-way, rectangular, semicircular, sawtooth, single-way, trapezoidal); performs complete processing of screws for micrometers; trims, drills, bores and taps caliper nuts with a cutting length of more than 50 mm; processes discs for universal chucks of metalworking machines; grinds and bores benches and ball joints with a radius of more than 100 mm according to a template; processes cylindrical gears of various diameters and bearing shields.
Features of the profession of a lathe-borer
A lathe-borer is an important person in an enterprise. Its main task is the processing of elements - blanks, from which various parts are subsequently assembled. The raw material can be wood, metal, plastic, etc.
The specialist also determines the depth of the details. A specific one is selected depending on the individual characteristics (properties) of the raw material and the parameters of the cutter. The boring machine fixes the part and begins processing it. The output should be a workpiece, the dimensions of which fully correspond to the specified parameters indicated in the drawing and in terms of reference. Only in this case the work of a lathe-borer is considered productive and effective, but otherwise it is useless work.
In his work, the boring machine uses not only the machine mechanism, but also complex measuring instruments. The latter include indicators and micrometers.
Another variety
A turner working on a milling machine is a milling machine operator. It processes hard materials (metal, wood, etc.) through the operation of a cutter. IN production process In any factory or enterprise, this employee plays a key role.
Tasks performed by a turner:
- operations related to processing parts according to ordered parameters;
