What does a fitter do?

The fitter is a kind of physical labor in cutting, mechanical assembly and repair, so it is named because it often clamps the workpiece with a vise on the workbench.

The fitter's operations mainly include chiseling, filing, sawing, scratching, drilling, reaming, tapping, tapping, scraping, grinding, correcting, bending and riveting. Fiddler is the oldest metalworking technology in mechanical manufacturing. The fitter's main task is to process parts. The fitter can do some machining that is not suitable or can't be solved by mechanical methods. Such as marking, precision machining, inspection and repair in the process of parts processing.

The fitter also needs to assemble and assemble the parts according to the assembly technical requirements of mechanical equipment, and only after adjustment, inspection and debugging can it become qualified mechanical equipment. When the machinery fails, is damaged or its accuracy drops after long-term use, it should also be maintained and repaired by the fitter.

Safety matters of fitter operation

1. The file is a right-handed tool and should be placed on the right side of the vice. When placed on the vice, the handle of the file should not be exposed outside the vice table, so as to avoid touching the ground and hurting the foot or damaging the file.

2. A useless file with a handle or a file with a cracked handle cannot be used, and the file cannot be used as a tool for disassembly, knocking and prying to prevent the file from being broken due to fragile materials.

3, when filing, the file handle can't touch the workpiece, so as to avoid accidents caused by the file handle falling off. When filing, use one side of the knife first, and then use the other side when this side is dull. When filing, make full use of the effective working face of the file to avoid local wear.

4. You can't blow filings with your mouth to prevent iron filings from entering your eyes, and you can't wipe the surface of filings with your hands.

5. Files should not be used as crowbars or hammers. In order to prevent the file from wearing too fast, do not file the hard skin of the blank or the hardened surface of the workpiece with a file, but use other tools or the indented front end and side teeth first.
