1. "One millimeter" is a fairly large scale in the machinery industry, and even in the entire manufacturing industry. If you see an advertisement like "accurate to the millimeter level" on TV one day, remember to blacklist this company.
2. "Automation" does not mean "robotization". Robots are usually only used in a small part of the automated assembly line. Why? Because it is not necessary.
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 work such as deburring.
4. Chrome plating (ge), generally those who study machinery know that it is read as du'ge, because the pronunciation of du'luo cannot be typed in pinyin. However, it is still du'luo in daily use, because it is to distinguish chromium from cadmium.
5. Quenching (cui), the daily spoken language in the industry generally uses "dip fire" because it is to distinguish it from "annealing". In the noisy workshop of the steel plant, 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, it is to dip the hot workpiece into the medium, so it is called "dipping fire", but some people say that it was changed to avoid the taboo of "brittle".
6. In the past two years, artificial intelligence has been seen to be faster than the sky and the earth, but in actual mass production, most of it can only process production data for the time being.
7. 3D printing (rapid prototyping) is a technology that was actually produced more than 30 years ago and then dug up by some media with ulterior motives. The current progress of this technology basically depends on the progress of materials science.
8. Few machines can work exactly as designed after they are made. In this case, on-site debugging is required.
9. After working in this industry for a long time, you can really tell the length of the bolt in your hand without measuring it with a ruler, and what size wrench to use.
10. "Light" refers to "fine" and "the last time". For example, "light knife" refers to "the knife for fine turning" and "light knife" refers to "the last knife for fine turning". The scope of "polishing" is too broad. "Fine grinding", "fine milling", "fine turning", etc., generally refer to the last time, which requires higher precision. "Fine work" means finishing the surface of the workpiece to improve its smoothness.
11. The names of rough processing are different in the north and south. The south is called "roughing"; the northeast is called "pulling roughing".
12. Picking threads, picking buckles: turning threads.
13. Buckles: threading.
14. Tempering: tempering.
15. Sào: taper, slope, refers to the workpiece with one end larger than the other. Most people read it as [shāo].
16. Pu: unqualified shape and position accuracy, such as uneven boards, non-round discs, rotation and swing, and poor coaxiality.
17. Purple (pronounced shai): a pigment used by fitters to apply to the surface of workpieces to facilitate marking.
18. Le knife: Due to extrusion deformation, the tool plastic deformation can no longer cut, generally refers to milling cutter.
19. Beat knife: The tool breaks and breaks.
20. Wai (wa) knife: The tool pierces the workpiece, causing the workpiece to be defective.
Picture
21. Le: Use carbide tools to finish at high speed. Because the cutting at this time is extrusion processing, it is called Le. Generally speaking, it is just a verb, and there must be appropriate language environment before and after, such as: This active alloy knife is leash and it is light.
22. Dao: 0.01 mm, Northeast.
23. Silk: 0.01 mm, South.
24. Ge: millimeter, for example, 10 mm is called 10, for example: This work still has 10 quantities.
25. Milling: reamer, but it seems that this is less said.
26. Wind milling: a rotating tool similar to a milling cutter installed on a wind grinding wheel, used by fitters.
27. Bend ruler: a right angle ruler.
28. Pliers: a broad term, depending on who you are talking to and how the other person understands it. People often make mistakes when borrowing things. For example, vise, anything with the word "pliers" is considered, but not "fitters".
29. Wind bag: an air pressure container, which looks a bit like a gas tank.
30. Crank: anything that can be turned by hand is considered, such as a handwheel.
31. Kilogram spanner: a torque spanner.
32. Clamp: something used to fasten a stack of thin iron plates together, similar in function to a bench vise, shaped like the letter D, with the vertical part being a screw.
33. Shell: chip breaker.
34. Shell opening (qiao, fourth tone): grinding chip breaker on a lathe tool.
35. Rush work: The key is the word "rush". Hand-eye closed-loop servo, 2-axis linkage, two-handed stepping, "human-controlled" machine tools use both hands to shake the handwheel to control the speed of each slide and process more complex shapes. Generally, lathes rely on spatial sense and templates, and milling machines rely on the lines drawn by fitters. Experts can control the error within 20 passes, and strong metal mold milling workers can even process 2 and a half axes.
36. Roughing the outer circle: turning the outer circle. Rough turning the outer circle of the rough blank is also called black skin.
37. End plane: turning the plane.
38. Tap tapping: tap tapping (different pronunciation).
39. Baking (bei) should all be read as accompanying (pei). "Baking" refers to a heating process in which iron ore is heated to 200-300℃ lower than its melting temperature. Through such heating, the iron ore undergoes chemical changes in a solid state, improving its metallurgical properties.
40. Leaching (jin) should be pronounced as leaching (qin). For example: using blast furnace slag from a steel plant as raw material, acid leaching and assisted leaching methods were used to study the leaching (qin) rate of iron and aluminum. In fact, leaching is a commonly used process in hydrometallurgy, and it is an extraction process used for iron, copper, zinc, and gold. Generally, old people in the industry do not pronounce it (jin).
41. Casting (pi) is often pronounced as casting (pei). Casting (pei) is the product obtained by casting molten steel from a steelmaking furnace through a continuous casting machine. It is not a finished product and needs to be rolled to become steel. Of course, both casting (pi) and casting (pei) are pronounced in mainland China, while Taiwan pronounces casting (pei).
42. Do not pronounce rolling (zhagang) as pressing (yagang). Those who have not been exposed to the steel industry may know that the word "轧" often appears in words such as "轧(ya) Malu", "轧(ya) System", and "垮(ya)". However, once you enter the metallurgical industry, this word has to be pronounced (zha), such as the common rolling roller, rolled steel, rolling mill, etc.
