Which parts need fitter's operation in automobile maintenance?

Machining and repair need fitter operation.

The fitter's operations mainly include chiseling, filing, sawing, marking, drilling, reaming, tapping and tapping (see thread processing), scraping, grinding, correcting, bending and riveting. Fiddler is the oldest metalworking technology in mechanical manufacturing.

Main tasks: mainly divided into the following parts processing, equipment maintenance, manufacturing and maintenance.

Type of work:

Chief assembler: One who assembles, trims and processes parts.

Machine fitter: Mainly engaged in the maintenance and repair of various mechanical equipment. Tool fitter: Mainly engaged in the design, manufacture and repair of tools, molds and cutters.

Bench level:

Primary (national vocational qualification level 5), intermediate (national vocational qualification level 4), advanced (national vocational qualification level 3), technician (national vocational qualification level 2) and senior technician (national vocational qualification level 1).

Assessment methods: divided into theoretical knowledge examination and skill operation examination. The theoretical knowledge test adopts the closed-book written test method, and the skill operation test adopts the on-site practical operation method. Both the theoretical knowledge test and the skill operation test adopt the 100 scoring system, and the score above 60 is qualified. It is also necessary to comprehensively evaluate technicians and senior technicians.

The fitter's main task is to process parts: some processing that is not suitable or can't be solved by mechanical methods. For example: scribing in the process of machining parts, precision machining (such as scraping templates, manufacturing molds, etc. ), inspection and maintenance, etc. Assembly: according to the assembly technical requirements of mechanical equipment, the parts are assembled, adjusted, inspected and debugged to make them qualified mechanical equipment.
