There is some knowledge that is unpopular in the outside world, but common sense in the workshop. These common senses are hard to find even in books. As a driver, can you read a few? Welcome to share! 1. "One millimeter" is a considerable scale in the machinery industry, even in the entire manufacturing industry. If you see an ad like "accurate to the millimeter" on TV someday, remember to blacken the company. 2. "Automation" is not equal to "robotization". The robots that are used are usually only a small part of the automated pipeline. why? Because it is not necessary. 3. Robots are rarely used directly in machining processes, especially metal cutting. Because the reaction force of the cutting metal can give up the arm of most robots, except for the deburring. 4, chrome (ge), the general learning of machinery is known to read duge, because reading duluo with Pinyin can not hit the word. But the daily use is still duluo, because it is to distinguish between chromium and cadmium. 5, quenching (cui) fire, the industry's daily spoken language generally uses "bonfire", because it is to distinguish from "annealing." In the steel mill workshop, the sound is noisy, it is difficult to distinguish between quenching and annealing. As for why this pronunciation is called, it is actually related to the actual operation of quenching. In fact, it is called "bonfire" when taking hot objects, so some people say that it is changed because of avoiding "crunchy". 6. In the past two years, the artificial intelligence of the second and second seconds, in the actual mass production, most of the time can only deal with the processing of production data. 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 progress of this technology at this stage is basically dependent on advances in materials science. 8, very few machines can be made to work in the same way as the design, this time you need on-site debugging. 9, this line has been working for a long time. I can really see the length of the bolt in the hand without taking the ruler, and how much wrench is used. 10. “Light†refers to “fine†and “last timeâ€. For example, "light knife" refers to "the knife of the fine car", and "light knife" refers to the "last knife of the fine car." The scope of "light" can be too wide, "fine grinding", "finishing", "fine car", etc., generally refers to the last time, requiring higher precision. “Lightingâ€, finishing the surface of the workpiece to improve its smoothness. 11. The name of rough processing in the north and south is different. The south is called “opening roughâ€; the north is called “raising wastelandâ€. 12, pick thread, pick: thread. 13, the buckle: the wrench thread. 14, smoldering: temper. 15, tip (shà o): taper, slope, refers to the workpiece is big and small, the average person has read into [ shÄo ]. 16. Park: The accuracy of the shape and position is unqualified. If the board is not flat, the disc is not round, the swing is swung, and the coaxiality is not good. 17, purple (pronounced shai): the fitter used to smear the surface of the workpiece to facilitate the marking of the pigment. 18, Le knife: Because of the deformation of the extrusion, the tool can not be cut by plastic deformation, generally multi-finger milling cutter. 19. Knife: The tool is cracked and broken. 20, å´´ (Watt) knife: The tool is inserted into the workpiece to make the workpiece defective. 21, Le: high-speed finishing with carbide tools, because the cutting is extrusion processing, so called Le, generally speaking, it is just a verb, before and after the appropriate language environment, such as: this It’s light to use the alloy knife. 22, Road: 0.01 mm, northeast. 23, silk: 0.01 mm, the south. 24, a: mm, such as 10 mm, said 10, for example: this activity has 10 quantities. 25, milling: reamer, but it seems that there is less. 26. Wind milling: Rotary cutters similar to milling cutters installed on wind-grinding wheels are used for fitters. 27, curved feet: square. 28, pliers: broad meaning, to see who said, and the other side to understand, borrowing things often mistakes. For example, the vise, as long as there are clamps, the fitter does not count. 29, wind bag: air pressure capacity, looks a bit like a gas tank. 30, the handle: hand cranking are counted, such as the hand wheel. 31, kg wrench: torque wrench. 32. Card Barrier: The thing used to fasten a stack of thin iron plates together. It functions like a vise. The shape is like a d-shape. The vertical is a screw. 33, shell: chip breaker. 34, open shell (qiao four sounds): turning knife grinding chip breaker. 35, catching up: focus on a 'catch' word. Hand-eye closed-loop servo, 2-axis linkage, two-step stepping, "human control" machine tool shakes the handwheel with both hands, controls the speed of each slide, and processes more complicated shapes. The general lathe depends on the space and the model. The milling machine relies on the line of the fitter. The master can control the error within 20 channels, and the powerful gold miller can even process the two axes. 36. The outer circle: the outer circle of the car. The outer circle of the rough car's hair is also called the black skin. 37, end plane: car plane. 38, taper: silk tapping tapping (different pronunciation). 39, baking (bei) burning pass to read as (pei) burning. "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 such heating, the iron ore undergoes a chemical change in a solid state to improve its metallurgical properties. 40, dip (jin) out to be dip (qin) out. For example, the blast furnace slag of steel plant is used as raw material, and the rate of iron and aluminum immersion (qin) is studied by acid leaching method and assisted immersion method. In fact, leaching is a commonly used process in wet smelting. Whether it is iron or copper, zinc or gold, the extraction process is used. Generally, the elderly are not reading (jin). 41. The slab (pi) is often read as a slab (pei). The pei is a product obtained by casting a molten steel made from a steelmaking furnace through a continuous casting machine. It is not a finished product and needs to be rolled to become a steel. Of course, the mainland reads both the slab (pi) and the pei (pei), while Taiwan reads the pei. 42. Rolling (zha steel) should not be read as pressure (ya) steel. The words “rolling†that have not been exposed to the steel industry are often found in the words “rolling (ya) roadâ€, “rolling (ya) system†and “rolling (ya)â€, but once in the metallurgical industry, the word Read (zha), such as common rolls, steel rolling, rolling mills, etc.
The Angle Grinder is a power tool used mainly for surface and circumference grinding (abrasive cutting or cut-off grinding) on various materials, but mainly metal. The mini angle grinders come with a speed of 10000RPM and 115/125mm disc diameters; large angle grinders are designed for heavy duty applications. They feature 180 or 230mm disc diameters and 1200 to 1500 watt.
