Responsibilities of a 3rd category carousel operator
This specialty is not suitable for people with hypersensitive skin, visual defects, chronic diseases of the musculoskeletal and cardiovascular systems, as well as the respiratory system. Therefore, the choice should be made carefully so that you do not have to make corrections later work book. Responsibilities of a rotary turner Varieties of work of this specialist: - processing of complex workpieces on specialized equipment or on a rotary machine using fixtures and tools; - precision turning, boring holes; - thread cutting; - turning surfaces of cylindrical (conical) shape, using several cutting tools; - plasma-mechanical processing of workpieces; - processing of solid-rolled wheels to a given size after rolling.
In production associated with machining on lathes, there must be a job description for a turner, which details the requirements for skill and operations performed in accordance with the qualifications of the machine operator. The document contains clauses on compliance with safe work rules, labor discipline and other worker duties. A separate paragraph lists his rights.
General document structure
IN work instructions turner, some points may vary, depending on the size and specifics of the enterprise. The rights and responsibilities of the machine operator are mandatory, depending on the category. Abilities and skills, requirements for professional standard a general-purpose turner and a low-skilled assistant. A standard document contains main sections.
- General situation. Includes information about the machine operator's subordination and educational requirements.
- Job responsibilities and work performed, taking into account qualifications.
- Responsibility of the performer of certain types of work.
- Machine operator's rights.
The job description is developed on the basis of the issued order of the chief manager. It regulates the conditions for the hiring and dismissal of a machine operator, his subordination. The list of responsibilities indicates what a turner of each category must know and be able to do.
As required by labor legislation, 1 copy of the instruction is kept by the chief manager of the enterprise, 2 copies by the head of the unit to whom the worker is directly subordinate. If desired, a copy of the instructions is made to the worker and given to him.
All the duties of a turner fit into 3 points.
- Preparing for work.
- Carrying out work in accordance with technical documentation and assignments.
- Checking the dimensions and class of roughness on completed parts. Self-control of quality.
For high-quality manufacturing of products, it is important to conscientiously perform the duties of a turner when preparing workpieces for processing. He must:
- check the markings on forgings and castings, or paint on rolled products;
- produce visual inspection for defects;
- make sure the sizes match;
- check the accompanying documentation.
If defects or discrepancies in size and material are detected, you must immediately inform your immediate supervisor without starting processing.
Machine operators with low qualifications and little experience are required to know their own and similar equipment and conscientiously sharpen parts on it. The instructions have expanded service job responsibilities universal turners. In addition to processing parts with a high accuracy class and complex configuration, they are required to train machine operators machine shop having 2nd and 3rd category. A general-purpose turner usually has assistants or apprentices. He conveys to them his processing experience, features different materials, basics of using devices and specialized tools. All this is written down in the job description of a machine operator with a high rank.
Only by independently checking the part in all dimensions can a turner of any level be confident in the correctness of its manufacture and hand over his products to the acceptance team or transfer them for further processing.
High-quality task performance is impossible without self-control.
The instructions for a 2nd category machine operator include responsibilities for chip removal. In addition, he has the right to undergo training and certification to obtain higher qualifications.
