Some knowledge is unpopular in the outside world, but it is common sense in the workshop. This common sense is hard to find even in books. As an industry person, how can you not understand these things?
1. "One millimeter" is a fairly large scale in the machinery industry, even in the entire manufacturing industry. If one day you see an advertisement like "accurate to the millimeter level" on TV, remember to block this company.
2. "Automation" is not equal to "robotization". Those who can use robots are usually only a small part of the automated assembly line. Why? Because there is no need.
3. Robots are rarely used directly in processing procedures, especially metal cutting. Because the reaction force of cutting metal can break the arms of most robots, except for delicate tasks such as deburring.
4. Chromium plating (ge). Generally speaking, those who study mechanics know to read du'ge, because du'luo cannot be typed out with pinyin. But daily use is still du'luo, because it is necessary to distinguish chromium from cadmium.
5. Quenching (cui) fire, the daily spoken language in the industry generally uses "dipping fire", because it is to distinguish it from "annealing". Once a layman said that I read it wrong, and I just looked at him like this.
6. In the past two years, artificial intelligence, which has been watching every second, can only process production data in actual mass production.
7. 3D printing (rapid prototyping) is a technology that was actually produced more than 30 years ago and was dug up by some media with ulterior motives. Advances in this technology at this stage are largely dependent on advances in materials science.
8. There are very few machines that can work exactly as designed after they are made. At this time, it is necessary to on-site (xia) field (Ji) adjustment (er) test (zheng).
9. After working in this industry for a long time, you can really see the length of the bolts in your hand without taking a ruler, and how big a wrench you use.
10. "Light" refers to "fine" and "last time". For example, "Guang Dao" refers to "the knife of the fine car", and "Guang Yi Dao" refers to "the last knife of the fine car". The scope of "lighting" is too wide. "Finish grinding", "finish milling", "finish turning" and so on generally refer to the last time, which requires high precision. "Light living", finishing the surface of the workpiece to improve the smoothness.
11. The north and the south have different names for rough processing. The south is called "open rough"; the northeast is called "pull waste".
Quenching (cui) fire must be said as dipping (zhan) fire
"Quenching (cui) fire" is read as "dipping (zhan) fire" is actually to distinguish it from another opposite process "annealing". In the steel factory workshop, the sound is noisy, and it is actually difficult to distinguish between quenching and annealing. As for why it is called this pronunciation, it is actually related to the actual operation of quenching. In fact, the hot workpiece is dipped in the medium, so it is called "dipping fire", but some people say it was changed because of the taboo of "brittleness".
If you pronounce it as "cui (cui) fire" in a business setting, the other party will immediately know that you are a novice.
Roasting (bei) should be pronounced as accompanying (pei) burning
"Roasting" refers to a heating process in which iron ore is heated to 200-300°C lower than its melting temperature. Through such heating, iron ore undergoes chemical changes in a solid state to improve its metallurgical properties.
Of course, this word is pronounced (bei) in Mandarin, but the master craftsmen in the factory are used to pronouncing (pei) to burn, so let’s follow it.
Dioxin (wu) rather than "dioxin"
The Chinese name of the poisonous substance "Dioxin" should be "dioxin [wu fourth tone] ying", not "dioxin", but in fact, many news reports refer to this substance as "dioxin". Lah, that's not right.
Although evil and evil are similar in form and have the same pronunciation, they have different meanings. The English name of the substance is "Dioxin", where "Di" means "two", "ox" means "oxygen-containing heterocyclic compound", and "in" means that it is a "hexacyclic compound without nitrogen atoms". member ring". Dioxin expresses the meaning of "Dioxin" more accurately.
Dip (jin) out to read as dip (qin) out
For example: using blast furnace slag from iron and steel plant as raw material, use acid leaching method and leaching method to study the leaching (qin) yield of iron and aluminum. In fact, leaching is a commonly used process in hydrometallurgy. Whether it is iron, copper, zinc, or gold, it is a useful extraction process. Generally, the elderly in the industry do not read (jin).
Chromium (ge) must be pronounced as Luo (luo)
"Chromium" pronounced "Luo" is basically found in all fields, whether it is a factory master, a university teacher, or a steel trader. All college students majoring in materials science, metallurgy, and metallurgy may have this experience. At first, they wondered if the teacher mispronounced "chromium", but after listening to it too much, they let it go. They are often chromium (ge) Used interchangeably with luo.
Billet (pi) is often read as billet (pei)
Casting embryo (pei) is the product obtained after the molten steel smelted in the steelmaking furnace is cast by the continuous casting machine. It is not a finished product, and it needs to be rolled to become steel. Of course, the mainland reads billet (pi) and embryo (pei), while Taiwan reads embryo (pei).
Rolled (zha) steel should not be pronounced as pressed (ya) steel
picture
Those who have never been in the iron and steel industry may often see the word "rolling" in the words "rolling (ya) road", "rolling (ya) system" and "dumping (ya)", but once it comes to the metallurgical industry, this word has to be Read (zha), such as common rolls, rolling steel, rolling mills, etc.
1. Pick thread, pick buckle: car thread
2. Set buckle: screw thread
3. Dip in fire: quenching
4, smoldering: tempering
5. Tip (sào): taper, inclination, which means that the workpiece is large at one end and small at the other end
Most people read [ shāo ]
6. Piao: The shape and position accuracy is unqualified, such as the board is not flat, the disc is not round, the rotation swings, and the coaxiality is not good
7. Chromium: Pronounced "Luo"
8. Purple (pronounced shai): The paint used by the fitter to smear the surface of the workpiece to facilitate marking.

15. Light knife: finishing tool, generally refers to the spring finish knife of lathe
16. Light work: finishing the surface of the workpiece to improve the finish.
17. Le: finish machining with carbide tools at high speed, because the cutting at this time is extrusion processing, so it is called Le. Generally speaking, it is just a verb, and there must be an appropriate language environment before and after, for example: this Use an alloy knife to strangle it and it will be light
18. Road: 0.01 mm, northeast
19. Silk: 0.01 mm, South
20. Units: millimeters, for example, 10 millimeters are called 10 pieces, for example: there are still 10 pieces in this job
21. Miller: reamer, but it seems that there are relatively few people who say that
22. Wind milling tool: a rotating tool similar to a milling cutter installed on a wind grinding wheel, used by a fitter
23. Curved ruler: square ruler
24. Pliers: The meaning is broad. It depends on who you are talking to and understanding with the other party. You often make mistakes when borrowing things. For example, vise, as long as it has the word pliers, it is counted, and the fitter is not counted.
25. Wind bag: air pressure container, which looks a bit like a gas tank
26. Crank handle: all of which are hand-cranked and rotated, such as handwheels

31. Shell opening (qiao4): Turning tool grinding chip breaker
32. Catch up: the focus is on the word "catch". Hand-eye closed-loop servo, 2-axis linkage, stepping with both hands, "man-controlled" machine tool shakes the handwheel with both hands, controls the speed of each slide, and processes more complex shapes. Ordinary lathes rely on the sense of space and the alignment of the template, while milling machines rely on the lines drawn by the fitter. Experts can control the error within 20 lines, and powerful metal millers can even do 2-axis semi-machining.
33. Wei (tile) knife: The knife penetrates into the workpiece, causing the workpiece to be damaged. ——We can also call it "Zha Dao"
34. Grilling the outer circle: car outer circle. The outer circle of rough car embryos is also called black leather.

36. Tap Gongsi: tap tapping. (pronounced differently)
Noun explanation "light": verb. Generally refers to "fine" and "last time". For example, "Guang Dao" refers to "the knife of the fine car", and "Guang Yi Dao" refers to "the last knife of the fine car". The scope of "lighting" is too wide. "Finish grinding", "finish milling", "finish turning" and so on generally refer to the last time, which requires high precision.
