This knowledge, only in the workshop to know!

2020-05-21 15:26

There is some knowledge, which is unpopular in the outside world, but common sense in our machinery 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" in the machinery industry is a considerable scale, even in the entire manufacturing industry. If you see an advertisement like "accurate to millimeter level" on TV one day, remember to pull the company black.
2, "automation" is not equal to "robotization", will use the robot is usually only a small part of the automation pipeline. Why? Because there's no need.

Robots are rarely used directly for machining processes, especially metal cutting. Because the reaction force of cutting metal can push the arm of most robots, except for the fine work of deburring.

4, chrome plating (ge), generally learn mechanical know is to read du'ge, because reading du'luo can't type words in pinyin. But daily use is still du'luo, because it is to distinguish chromium from cadmium.
5, quenching (cui) fire, the industry's daily spoken language is generally "dipped in fire", because it is to distinguish from "annealing. Once a layman said I read it wrong, and I looked at him like this.
6. In the past two years, looking at the artificial intelligence in seconds, most of the actual mass production can only process the production data for the time being.
3D printing (rapid prototyping) is a technology that was actually produced more than 30 years ago and then dug up by some ulterior media. The progress of this technology at this stage basically depends on the progress of materials science.
8. Few machines can work as designed after they are made. At this time, it is necessary to adjust (er) the current (xia) field (Ji) and try (zheng).
9. After a long time in this line of work, I can really see the bolt specification and length in my hand and how big a wrench I use without measuring with a ruler.
10. "Light" means "fine" and "last time". For example, "light knife" refers to the "fine turning of the knife", "light knife" refers to the "fine turning of the last knife". The scope of "light" can be too wide, "fine grinding", "fine milling", "fine turning" and so on, generally refer to the last time, requiring higher precision. "Light live", finishing the surface of the workpiece to improve the finish.
11, the north and the south for rough processing is not the same, the south is called "open rough"; The northeast is called "pulling wasteland".


12, pick thread, pick buckle: car thread.
13. Clasp: thread of tooth clasp.
14, stuffy fire: tempering.
15, tip (sào): taper, slope, refers to the workpiece head big and head small, the average person let room read [shāo].
16. Park: The shape and position accuracy is not up to standard, such as uneven board, non-round disc, rotary swing, and poor coaxiality.
17, purple (pronunciation shai): fitter used to smear the surface of the workpiece to facilitate the marking of the pigment.
18. Leveling: Due to extrusion deformation, the cutting tool is plastic and cannot be cut. Generally, it refers to milling cutters.
19. Knife beating: the knife cracks and breaks.

20, Wei (tile) knife: the tool into the workpiece, so that the workpiece defect.

21. Le: Use hard alloy cutting tools for high-speed finishing. Because the cutting at this time is extrusion processing, it is called Le. Generally speaking, it is just a verb. It should be matched with appropriate language environment before and after. For example, this flexible alloy cutting tool will be used up in one go.

22. Road: 0.01mm, northeast.
23. Silk: 0.01mm, south.
24, mm: mm, for example, 10mm is 10, for example, there are still 10 in this job.
25. Mill: Reamer, but it seems less to say so.
26. Wind milling: a rotating tool similar to a milling cutter installed on a wind grinding wheel, for fitter use.
27. Bending ruler: square ruler.
28. Pincers: The meaning is broad. It depends on who you talk to and who you understand. You often make mistakes when borrowing things. For example, vise, as long as there is a clamp word, fitter does not count.
29. Air bag: air pressure container, which looks a bit like a gas tank.
30. Crock handle: hand-cranked rotation counts, such as handwheel.
31.Kg wrench: torque wrench.
32, card bar: used to fasten a stack of thin iron plates together, the function is similar to a vise, the shape is like a D, the vertical is a screw.
33, shell: chip breaking groove.
34. Shell opening (qiao four sounds): turning tool grinds chip breaking groove.
35. Catch up: The focus is on the word "catch up. Hand-eye closed-loop servo, 2-axis linkage, two-hand stepping, "human-controlled" machine tool shaking hand wheel with both hands, controlling the speed of each sliding board, and processing more complex shapes. Generally, lathes rely on space feeling and matching templates, milling machines rely on fitter lines, experts can control the error within 20 lanes, and tough gold milling workers can even semi-process in 2 axes.
36. Grabbing the outer circle: the outer circle of the car. The outer circle of rough car wool embryo is also called steak black skin.
37. End plane: car plane.
38. Tap thread: tap thread (different pronunciation).
39, baked (bei) burn all to read accompany (pei) burn. "Roasting" refers to a heating process in which iron ore is heated to a temperature 200 to 300°C lower than its melting temperature. By this heating, the iron ore undergoes chemical changes in the solid state to improve its metallurgical properties.
40, immersion (jin) out to read into immersion (qin) out. For example: iron and steel plant blast furnace slag as raw material, the use of acid leaching and leaching method to study iron, aluminum leaching (qin) rate. In fact, leaching is a commonly used process in wet smelting. Whether it is iron, copper, zinc or gold, it is an extraction process that is useful. Generally speaking, the elderly do not read it (jin).
41, cast billet (pi) is often read into cast billet (pei). The cast blank (PEI) is the product obtained by the continuous casting machine after the molten steel made by the steelmaking furnace is not a finished product, but also needs to be rolled to become steel. Of course, both cast blank (pi) and cast embryo (pei) are read in mainland China, while cast embryo (pei) is read in Taiwan.


42, rolling (zha steel) do not read as pressure (ya) steel. The common words "rolling" that may not have been exposed to the steel industry mostly appear in the words "rolling (ya) road", "rolling (ya) system" and "tilting (ya)", but once you get to the metallurgical industry, you have to read (zha) the word, such as common rolls, steel rolls, steel mills, etc.
