What do fitters do in general? What does a fitter do

All kinds of metalwork were made by blacksmiths of the time (similar to today's casters and blacksmiths). With the continuous development of society and production technology, the casting and forging processes have also developed, so there is a new division of labor in the process. In the 14th and 15th centuries, the fitter process became independent from the casting and forging process and became a specialized type of work.

In the beginning, fitters could only make simple metal products by hand, such as locks and rings, but later they became more complex and now they are able to make machine parts and assemble machines. Fitter is an important type of work in modern industry.

The fitter operation is mainly carried out with hand tools on the vise, so it is called a fitter. This kind of work is more complex and detailed, and the specific operations include: part measurement, scribing, chiseling, filing, sawing, drilling, holes, reaming, tapping and threading, straightening and bending, riveting, scraping, grinding, tinning and soldering, bearing alloy casting, simple heat treatment (quenching), sheet metal blanking (thin plate), etc.

Fitter operations are mostly done by hand, sometimes mechanically.

During the war, the infantry always said to their comrades-in-arms of other arms: "Cannons cannot be loaded with bayonets, and it is up to us infantry to solve the battle." It can be said that the fitter is the most basic of all the machining processes. It is the "infantry" in various crafts.

Fitter basics.

First, the fitter overview.

Fitter is one of the important types of work in machinery manufacturing and plays an important role in the process of machinery production.

Fitter is a method of cutting metal surface with hand-held tools, and in the processing process, the use of vices, hand saws, files, drilling machines and various hand tools to complete the work that cannot be completed by current machining. The work of the fitter is characterized by flexibility, mobility, and is not limited by the position of the feeder, even if the emergence of various advanced equipment is inseparable from the fitter.

Second, the work content of the fitter.

The basic operations of the fitter include: marking, sawing, filing, drilling, reaming, countersinking, tapping and threading, scraping, grinding, assembly and disassembly.

There are three main aspects of the fitter's scope of work:

1. The surface that cannot be processed by the processing machine, such as the inconvenient surface inside the machine, the model with high precision, the mold, etc.

2. In addition to processing, the assembly of the machine can also be carried out.

3. Debugging and maintenance of machines or equipment.

I'm a mechanical major. Let's not talk about the definition in the book, I'll just say something intuitive!

Assembly fitter: the assembly and disassembly of mechanical equipment, for some complex machinery and equipment can understand the assembly process designed by engineers, and in some occasions with tolerance requirements, it can meet the external requirements of assembly.

Maintenance fitter: Carry out daily maintenance and repair of machinery, and solve problems by themselves without technicians for general mechanical failures. Ability to read drawings of complex parts and understand common mechanical failures.

Universal fitter: can carry out a variety of fitter operations. Including special parts processing, the realization of special processes, drilling and tapping buckles and so on. In short, all the parts you can imagine fitters can do ......

Fitter is a kind of machining worker, mainly engaged in the production and processing of metal products. They use a variety of hand and power tools, such as milling machines, drilling machines, CNC machine grip machines, etc., to cut, rotate, mill, drill, and shape on metal or other materials to produce parts and products of various shapes. Fitters often need Shan Jingqing to read drawings and blueprints, make measurements and mark-ups to ensure that the parts made meet the required specifications and quality standards.

In addition, they need to carry out machine maintenance and component repair work. The work of a fitter can be widely used in many different industries, such as Zezen manufacturing, automotive, aerospace, construction, etc.

<> pliers work mainly includes chiseling, filing, sawing, scribing, drilling, reaming, tapping and threading (see threading), scraping, grinding, straightening, bending and riveting. Fitter is the oldest metalworking technique in mechanical manufacturing.

There are three major advantages of fitter work, which are flexible processing, complex shapes and high-precision parts, and small investment, and the two major disadvantages are low production efficiency and high labor intensity, and unstable processing quality.

Fitters are mainly divided into machining parts, equipment maintenance, manufacturing and repair.

Machining parts: some machining that is not suitable or can not be solved by mechanical methods can be completed by fitters. Such as: marking in the process of parts processing, precision machining (such as scraping, frustration and making molds, etc.), inspection and repair, etc.

Assembly: The parts are assembled according to the technical requirements of the assembly of mechanical equipment, and the components are assembled and matched, and adjusted, inspected and tested, etc., so that they become qualified mechanical equipment.

Equipment maintenance: When the machinery fails during use, is damaged or the accuracy is reduced after long-term use, which affects the use, it should also be maintained and repaired by fitters.

Manufacturing and Repair: Manufacture and repair all kinds of tools, fixtures, gauges, molds and all kinds of professional equipment. Lee teased envy.

<>1. Responsible for the processing of the company's impulse current and DC accessories, and the assembly and installation of DC silicon stacks;

2. Familiar with the ability of punching, tapping, differential fitting, welding, flat grinding, milling, sawing and other assembly processes for assembly;

3. Assemble the product in strict accordance with the assembly process, and feedback the problems in the assembly to the designer in time;

4. The assembled products should be neatly placed in the identification area according to the regulations, and it is strictly forbidden to place them indiscriminately;

5. Abide by the safety operation procedures to ensure safe production;

6. Complete other tasks assigned by superiors temporarily.

Fitters have three major advantages (flexible processing, complex shapes and high-precision parts, small investment), and two major disadvantages (low production efficiency and high labor intensity, unstable processing quality).

1. Flexible processing In the occasion that is not suitable for machining, especially in the maintenance of mechanical equipment, fitter processing can obtain satisfactory results.

2. Skilled fitters with complex shapes and high-precision parts can process parts that are more precise and smooth than those processed by modern machine tools, and can process parts with very complex shapes that can not be processed even by modern machine tools, such as high-precision measuring tools, models, and molds with complex beginnings.

3. The tools and equipment used in the processing of small fitters are cheap and easy to carry.

4. Low production efficiency and high labor intensity.

5. The amount of processed orange liquid is unstable, and the level of processing quality is affected by the technical proficiency of workers.

1. Ordinary fitter: the person who assembles, trims and processes parts.

2. Mechanic fitter: mainly engaged in the maintenance and repair of various mechanical equipment.

3. Tool fitter: mainly engaged in the design, manufacture and repair of tools, molds, and round mascot knives.

Clamping work mainly includes chiseling, filing, sawing, scribing, drilling, reaming, tapping and threading (see threading), scraping, grinding, straightening, bending and riveting. Fitter is the oldest metalworking technique in machine building.

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

Type of work:Ordinary blade fitter: a person who assembles, trims and processes parts.

Mechanic fitter: mainly engaged in the maintenance and repair of various mechanical equipment. Tool fitter: mainly engaged in the design and manufacture of tools, molds, knives and repairs.
