What is a fitter?

Fitter mainly uses hand-held tools to process workpieces, which is also an indispensable type of work in mechanical manufacturing. Its basic operations include scribing, chiseling, sawing, filing, drilling, reaming, countersinking and reaming, tapping and buckling, scraping, grinding, correcting and bending, riveting and assembly. Fitter can be divided into general fitter, marking fitter, die fitter, scraping fitter, assembly fitter, machine fitter and pipe fitter according to their professional nature.

The basic operation of locksmith is as follows:

The fitter's operations mainly include chiseling, filing, sawing, marking, drilling, reaming, tapping and tapping (see thread processing), scraping, grinding, correcting, bending and riveting.

The fitter is the oldest metalworking technology in mechanical manufacturing. /kloc-after the 0/9th century, with the development and popularization of various machine tools, locksmiths are still the basic technology widely used in the process of mechanical manufacturing, although most of their work has been gradually mechanized and automated. The reason for this is the following：

Up to now, there is no suitable mechanized equipment to replace 1, marking, scraping, grinding, mechanical assembly and other locksmith work;

2. Some of the most sophisticated templates, molds, measuring tools and mating surfaces (such as guide surfaces and bearing shells) still need to rely on the skills of workers for precision machining;

3. It is still an economical and practical method to manufacture some parts by locksmith in the case of small batch production, maintenance or lack of equipment.

Extended data:

First of all, assemblers are generally divided into two categories:

1, mechanical maintenance fitter.

2. Assembly fitter: senior fitter, mold fitter, tool fitter, maintenance fitter, machine fitter, marking fitter, electrical fitter, marking fitter, sheet metal fitter, installation fitter, etc.

Second, the fitter work content can be divided into:

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

2. Assembly: Assemble the parts according to the technical requirements of mechanical equipment assembly, and the parts are generally assembled, and pass the? Adjustment, inspection and debugging, etc. Make it a qualified mechanical equipment.

3. Equipment maintenance: When the machinery fails, is damaged or its accuracy is reduced after long-term use, it should also be maintained and repaired by the fitter.

4. Tool manufacturing and repair: manufacturing and repairing various tools, fixtures, measuring tools, molds and various professional equipment.

The fitter needs to master a lot of knowledge, mainly including mechanical foundation, mechanical drawing, metal materials and heat treatment, tool fitter, assembly fitter and other processes.
