Repost: There is some knowledge that is obscure outside but is common sense in the workshop. Such common knowledge is hard to find even in books. As someone in the machinery industry, how many of these can you understand? 0 A/ C" X# j# H3 z; T& l+ U% ~ 2 R1 s% B% 1. “One millimeter” is a quite significant scale in the machinery industry, and even across the entire manufacturing sector. If one day you see an advertisement on TV with phrases like “accurate to the millimeter,” remember to block that company. 2. “Automation” is not the same as “robotization”; robots are typically used only in a small part of automated production lines. Why? Because it’s not necessary. - e$ A7 M- }4 U" S 3: Robots are rarely used directly in machining processes, especially in metal cutting. Because the reaction force from cutting metal can bend the arms of most robots, except for tasks like deburring that require precision. 4. Chrome plating (GE); those who study mechanical engineering generally know that it is pronounced as “du’ge”, as the pinyin for “du’luo” cannot be used to represent this character. But for everyday use, it is still du’luo, because chromium and cadmium need to be separated. 5. Quenching: In everyday industry terminology, the term “dip in fire” is commonly used, as it serves to distinguish it from \"annealing\". It’s noisy in the steel plant workshops, and it’s actually difficult to distinguish between quenching and annealing. As for why it is pronounced this way, it is actually related to the actual process of quenching; hot workpieces are dipped into the medium, which is why it is called \"dipping in fire.\" However, some say it was changed to avoid the character meaning \"brittle.\" 6. Over the past two years, despite the rapid development of artificial intelligence, in actual mass production it is still mostly limited to processing production data for now. - L0 Y4 z' B0 R$ w' M& T9 A! q 7. 3D printing (rapid prototyping) is a technology that actually originated over 30 years ago, and was later highlighted by some media outlets with ulterior motives. The current progress of this technology largely depends on advances in materials science. 8. Few machines function exactly as designed after being manufactured; in such cases, on-site adjustment is required. # d; f2 y# C: ]# @3 n 9 – After working with this for a while, it’s really possible to tell at a glance, without using a ruler, what the length of the bolts in use is, as well as what size wrench is needed. 0 M9 b4 `' }; {' M, b 10、「Light」refers to 「essence」, \"the last time\". For example, “light knife” refers to the tool used for finishing turning, while “final light knife” refers to the last pass in the finishing turning process. “The scope of “a final polishing step” is quite broad – terms like “precision grinding,” “precision milling,” and “precision turning” all refer to the last stage of processing where high precision is required. “\"Optical activation\" is used to refine the surface of workpieces, thereby improving their smoothness. 2 {- s1 _, R(B1 c7 y 11). The terms used for rough machining vary between the north and south; in the south, it is called “starting the roughing process”” ； In the northeast, it’s called “la huang”. 2 12. Thread selection, fastener selection: threading. * U1 T3 ? c& }2 { 13. Threaded sleeve: screw thread sleeve. $ V& J; k8 C/ m 14, Stalled flame: Tempering. 15. Shao (sào): Taper, slope; it refers to a workpiece that is larger at one end and smaller at the other. Most people pronounce it as . 16. Park: The form and position accuracy is unsatisfactory; for example, the plate is not flat, the disc is not round, there is rotational oscillation, and the coaxiality is poor. ' L’ L) H: D’ u, S1 G, L# z, c 17; Purple (pronounced shai): A pigment used by blacksmiths to coat the surface of workpieces to facilitate marking. 18. Blade wear: Due to compression deformation, the plastic deformation of the cutting tool prevents it from cutting; this term usually refers to milling cutters. 19. Blade breakage: The knife blade cracks and breaks apart. 20. Chipping tool: The cutting tool pierces into the workpiece, causing damage to it. 21. Le: It refers to precision machining at high speeds using cemented carbide tools; since the cutting process involved here is one of extrusion, it is called “le”. Generally, it functions as a verb and needs to be used within an appropriate contextual framework, for example: This work can be made smooth with just a quick cut using a cemented carbide tool. 22. Dao: 0.01 mm, northeast. 23. Silk: 0.01 millimeters, South. 24: units are millimeters; for example, 10 millimeters is referred to as 10 units. For instance, there are still 10 units of this work left. 0 C; e/ W/ h! \0 t) ~ 25, Milling tool: Reamer, though this term seems to be used less often. 26. Air mill: A rotating cutting tool similar to a milling cutter, mounted on an air grinder, used by fitters. 27. Bend ruler: Right-angled ruler. % L6 B$ }4 h% W) ^ 28. Pliers: The meaning is vague; it depends on who you are speaking to and on the other person’s understanding; mistakes often occur when borrowing things. For example, with pliers, anything that has the word \"plier\" in its name counts; fitters do not. 29. Air tank: A pressure vessel for air, somewhat similar in appearance to a gas cylinder. 30. Crank: Anything that rotates by hand counts, such as a handwheel. 31. Kilogram wrench: torque wrench. 32. Clamp: A device used to hold a stack of thin metal sheets together tightly; it functions similarly to vices, and its shape is similar to the letter D, with the vertical part being the screw. 33. Shell: Chip breaker groove. . `' a& y9 s% l% x+ z 34、Opening the shell (pronounced with the fourth tone): Grinding the chip flute on the cutting tool. " U3?# I l) d* 35: The key here is the word ‘rush’. It involves closed-loop servo control for hands and eyes, simultaneous movement of two axes, and step-by-step operation using both hands; the machine is controlled by manually turning handwheels to regulate the speed of various slides, thereby enabling the creation of relatively complex shapes. Ordinary lathes rely on spatial intuition and reference templates, while milling machines depend on lines drawn by fitters. Skilled operators can keep errors within 20 units, and highly proficient mold millers can even carry out processing with two and a half axes. 36. Turning the outer circle: Turning the outer surface of a circle. Turning the outer diameter of the rough blank is also known as removing the rough surface layer. 37. End plane: Turning plane. 8 Y8 X5 |! {0 S 38、Tapered tap for threading: Using a tapered tap to create threads (different pronunciation). 6 s# G# L) d. z! Y/ |7 |( H, s 39. The word \"bei shao\" should be pronounced as \"pei shao\". “\"Roasting\" refers to a heating process in which iron ore is heated to a temperature 200–300°C lower than its melting point; through this heating, chemical changes occur in the iron ore while it remains in a solid state, thereby improving its metallurgical properties. 40. “Jin chū” should be pronounced as “Qin chū”. For example, using blast furnace slag from steel plants as raw material, acid leaching and assisted leaching methods were employed to study the leaching rates of iron and aluminum. In fact, leaching is a commonly used process in hydrometallurgy; it is employed for the extraction of iron, as well as copper, zinc, and gold. Experienced professionals in this field generally do not use the term \"jin\" for it. 41. The term ‘cast billet’ (pi) is often pronounced as ‘cast billet’ (pei). A bloom is a product obtained by casting the molten steel produced in a steelmaking furnace using a continuous caster; it is not a finished product, and it must undergo rolling to become steel. Of course, on the mainland both pronunciations of \"cast ingot\" (pi) and (pei) are used, while in Taiwan it is pronounced as (pei). 2 R: j3 p9 V. O" m: ~ 42. Steel processed by rolling should not be pronounced as steel processed by pressing. Those who are not familiar with the steel industry may often encounter the character for \"rolling\" in words such as \"rolling roads,\" \"rolling production,\" and \"intrigue and oppression.\" However, in the metallurgy industry, this character is pronounced as \"zha,\" as seen in terms like rolling mills, steel rolling, and steel rolling machines.
