What is the work scope of the fitter?

The types of fitters include assembly fitters, repair fitters and die fitters.

Manual work in cutting, mechanical assembly and repair operations is named because it is usually used to clamp workpieces on the workbench. 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 machinery manufacturing.

Some machining that is not suitable or can't be solved by mechanical methods can be done by locksmiths. Such as: scribing and precision machining in the process of parts processing (such as scraping templates and making molds, etc.). ), inspection and repair, etc.

When the machine fails, is damaged or its accuracy drops after long-term use, it should also be maintained and repaired by the assembler.

Extended data:

Starting with the basic knowledge of fitter's operation, this paper first introduces the basic knowledge of mechanical drawing, dimensional tolerance, shape and position tolerance and surface roughness, and tries to be concise and to the point.

Then the fitter's operation skills, such as marking, sawing, chiseling, filing, scraping, grinding, bending and correcting, drilling and reaming, assembly and repair, are described in detail. The book is simple, intuitive, easy to understand and consult, which can lay a good foundation for beginners to enter the working state and further study as soon as possible and provide useful help.

The professional knowledge of frustration, sawing, hole machining, grinding, mold design, mold assembly and adjustment, fixture design, gear hob manufacturing technology, typical workpiece process analysis and typical workpiece production is integrated into the practical operation, which fully embodies the vocational teaching characteristics of "learning by doing" and "learning by doing" and is "referring to national standards and close to professional norms".
