Who has a lesson plan for fitter crafts! Relief!

I have written textbooks, which I can buy at bookstores

Fitter technology.

Chapter 1 Overview of Fitters.

1. Fill in the blanks.

1. Most of the fitters are used.

tools) and often perform manual operations on (vices).

2. When mechanical equipment is generated (malfunction).

Occurrence (damage) or accuracy (deterioration) after long-term use

When it affects the use, it is necessary.

Maintenance and repairs are carried out by (fitters).

3. The basic operations that fitters must master are: marking

Chiseling) (sawing).

Filing) drilling, reaming, countersinking, reaming.

Holes, tapping threads and (sleeve threads).

Scraping and (grinding).

Correction and (bending).

Riveting and (brazing).

Assembly, technology. Surgical measurements with simple (heat treatment) etc.

4. Fitter is one of the earliest and most technical types of work, and its main task is: marking (marking) on the workpiece

Machining zero. pieces), (assembly) and commissioning of machines, installation and (repair) of equipment, as well as (manufacturing) and (repair) of tools. 5

The equipment commonly used by fitters is (fitter table).

vice) grinder,

bench drills), vertical drills, etc.

6. The vice is a general fixture used to clamp the workpiece, and its specifications are expressed by (jaw width).

2. True/False Questions (Correct Drawing, Wrong Drawing).

1. All on the machine; The parts must be machined.

The manufacturing methods of parts blanks include forging, casting, and welding.

Parts that can be made by machining methods can be completed by fitters.

Ordinary fitters are mainly engaged in the production and repair of tools, molds, fixtures, measuring tools and samples.

The movable surfaces such as vice screws and nuts should be cleaned and lubricated frequently to prevent rust.

After the grinding wheel is started, it is possible to start grinding without waiting for the grinding wheel to rotate smoothly.

During grinding, the operator should stand on the side or diagonally opposite the grinding wheel, not directly opposite.

There are two types of vices: fixed and movable.

The cross-reticulation on the jaws is designed to prevent the workpiece from slipping and to make the clamping reliable.

When working vigorously on a vice, the direction of force should be towards the movable vise.

When grinding, the operator should stand on the side or opposite of the grinder to facilitate the work. （×

Hello, seeing that your question is about to be squeezed out of the list of questions by new questions, and if the question is not answered, points will be deducted and bounty points will be forfeited after the expiration date!

It's been a long time ago, no.

I have, that's the version I learned in school. But how do you give it to you? Do you want an electronic version?

Cutting depth when drilling: ap=d drill bit 2 24 2=12mm;

Cutting depth during reaming: ap (d reamer drill d drill bit) 2=(;

Cutting depth when hinging: AP (D D reamer drill) 2 (40 ;

Spindle speed during reaming: n 1000 vc d rpm and another feed f is a useless known condition.

The library is there! A lot!

If you like to be active and love to make small improvements in your skills, learn fitters. Fitters are generally in good health.

If you like to use your brain and are an analytical person, study electrician. Electricians are generally flexible.

Electricians are divided into strong electricity and weak electricity, strong electricity to test the qualification certificate, operation certificate, special attention to electricity safety.

The weakness is to engage in electronic control, generally through professional learning to get started, modern enterprises need this kind of people, the mind must be smart in order to learn to achieve good results.

It is more difficult for an electrician to learn well, and there is a certain amount of danger. The fitter is relatively simple and has a low risk factor. If the electrician is proficient in money, the fitter's income will be dwarfed.

In fact, to learn electrician, you must also know some fitter technology, as the saying goes, electromechanical is not separated.
