As a beginner in the machining industry, do you often get confused by the "slang" in the mouth of some "old drivers"? "Light", as mentioned in the title of this article, is a typical representative. "Light" usually refers to the last process of finishing. The source of this usage is said to be the surface finish of the workpiece. Its derivatives include "light knife" (finishing tool) and so on. The scope of "light" is very wide, which can refer to the final step of fine grinding, fine milling or fine turning process in processing. In the implementation of "light once", there are high requirements for machining accuracy. How about the "slang" in the machining industry? Isn't it simple? There are many examples like this. Let's make a simple inventory.
"Pulling waste" and "opening up rough"
The words "waste pulling" and "rough opening" have the same meaning and refer to the rough machining steps in machining. Compared with finish machining, rough machining requires less precision and higher machining speed. The word "reclaiming wasteland" may come from "reclaiming wasteland" or "reclaiming wasteland". It is thought to be relatively grounded. It is widely used in the machining industry in Northeast China. The word "bold" is popular in southern China.
"Dip in fire" and "stuffy fire"
"Dip in fire" is what we usually call quenching, "quench fire" is what we usually call tempering. These are important processes in heat treatment. The quenching stone austenitizes the steel and then cools it at an appropriate rate to make the workpiece undergo martensite and other unstable structural transformation. Tempering is a heat treatment process in which the quenched workpiece is heated to an appropriate temperature below the critical point for a certain time, and then cooled by a certain method to obtain the required structure and properties.
"Tao", "silk" and "Ge"
Literally, these words should represent a certain unit. Indeed, they are all length units, "Dao" and "silk" refer to millimeters, while "Ge" refers to 1mm. Among them, the rough name "Dao" is more popular in the machining field in Northeast China, just like the forthright character of northeast people; And "silk", a kind of elegant calling principle, is popular in the machining field in the south, which reminds people of the softness of southerners.
"Milling" and "air milling"
These two are about machining tools. "Milling" does not mean milling cutter, but reamer. It is a rotary tool with one or more cutter teeth, which is used to cut the thin layer of metal on the surface of the machined hole. It is a rotary finishing tool with a straight edge or a spiral edge, which is often used for hole enlarging or hole repairing. "Air mill" is a rotating tool similar to a milling cutter installed on the air wheel, which is usually operated and processed by fitters.
"Le Dao", "Da Dao" and "Wei Dao"
These three words are all some faults of cutting tools in the process of machining. Because of extrusion deformation, the "cutting tool" has plastic deformation and can no longer be used for cutting. This kind of accident usually occurs in milling cutters. "Cutting" means that the tool has cracked or broken, and it can no longer be used. It is not the tool that is damaged, but the workpiece. It refers to that the tool plunges into the workpiece, causing the workpiece to be damaged.
In addition to the above, there are many "slang" in machining, which is difficult to summarize. All beginners of machining should slowly understand their meanings through their own learning and accumulation, so as to better integrate into your circle.
