Laser column crystal is a very special kind of VUV grade LiF optics column. It is characterized by the ability to concentrate energy, expand and resonate through the entire crystal column, and then emit it from its tip. This is the energy emission of other crystal columns. The way is very different. Its shape is generally flat and narrow, slender, gradually gathered upward from the bottom of the wholesale LiF optics, just like a sword. The length ranges from a dozen centimeters to tens of centimeters. Its texture is generally relatively transparent compared to other crystal columns, most of which are concentrated in the middle and lower parts, sometimes crystal and texture will form some special symbolic patterns and patterns, and its top It is very clear. The color is generally common in white and brown crystal columns, rarely seen in purple, if one day you see the natural purple laser column crystal, then it is absolutely a coincidence, this is a rare treasure, is Every instrument that every spiritualist dreams of is to buy it anyway. So how do you choose a suitable laser column crystal for yourself? 1 Shape Length, thickness should be moderate. In general, fifteen centimeters to twenty-five centimeters of procurement customizable large size optical Window are enough to deal with common types of things. The thickness should be well held by hand. Because in actual use, there are often a lot of large-scale movements, so it is too long and too thick crystal column, not suitable for practical use and carrying, it is only used in some large-scale ceremonies. 2 Texture In my personal experience, the part that is held in the hand is preferably some crystal, which can play a role in aura filtering. The tip must be pure, because this is where the energy is concentrated and there is no impurity. As for the middle part, it is more casual. If there are texture patterns that form a special symbolic meaning, it is the best. Such a crystal column has a much stronger aura than a pure crystal column. 3 The common white and brown crystal columns are good choices. For the spiritualist, in order to better exert the power of the crystal column, it is necessary to have its own internal repair as the basis. It should be played with the organic cooperation to exert its greatest spiritual power. A lot of things don't have a crystal that is worth a price.

Introduction of cutting disc 1 Abrasive is a sharp, hard material used to grind the surface of the material. Abrasives are available in two categories: natural abrasives and synthetic abrasives. Many natural abrasives have been replaced by artificial abrasives. Generally, alumina, zirconia, silicon carbide, etc. are commonly used. 2 Cutting discs are tools for grinding, grinding and polishing. Most of the cutting disc for stainless steel are artificial cutting discs made of abrasive plus binder, and natural cutting discs directly processed from natural mineral rock. In addition to being widely used in machinery manufacturing and other metal processing industries, cutting discs are also used in the processing of food processing, the paper industry, and non-metallic materials such as ceramics, glass, stone, plastics, rubber, and wood. Here we mainly talk about the widely used cutting discs, which usually include two types: ordinary cutting discs and superhard material cutting discs: A common cutting disc refers to a cutting disc made of ordinary abrasive. According to the abrasive combination form, it is divided into a fixed cutting disc and a coated cutting disc, which can be divided into ceramic cutting discs and resin cutting discs according to different bonding agents. 2 superhard material cutting disc, mainly made of metal powder, metal oxide or CBN superhard material as filler, resin bond or ceramic bond or metal bond.

The basic concept of ordinary abrasive tools 1-1 the meaning of ordinary abrasives Abrasives are tools that bond abrasives to certain requirements, such as sharp and durable cutting wheel, and tiles, oilstones, grinding heads, abrasive pastes, etc., for grinding, grinding, and polishing workpieces. 1-2 structure of ordinary abrasive tools The grinding tool consists of three elements: abrasive grains, binders, and pores. The abrasive body is the main body of the grinding tool. The workpiece is exposed as a cutting edge by a shuttle angle exposed on the surface of the grinding tool. Bonding agent-bonding material, It acts as a fixed abrasive to give the tool shape, sufficient strength, and the required hardness. The vent is the gap inside the grinder, which has the effect of chip evacuation and the containment of coolant. The volume relationship of the three is: V abrasive ten V combined with punishment ten C vent: 100% In order to improve the cooling, lubrication and roughness properties of the abrasive tool, the substance filled with the impregnating agent in the pores of the grinding tool (such as sulfur immersion and wax immersion) may also be referred to as the fourth element. 1-3 characteristics of ordinary abrasive tools Abrasives include abrasives, particle size, hardness, texture, bonding, shape, and size. 1-4 classification of ordinary abrasives Due to the grinding method, the nature of the processed materials, the conditions of use, and the technical requirements of the workpieces, there are many types of abrasive tools and the classification of commonly used ordinary abrasive tools Methods as below: 1.4.1 by an abrasive fraction Oxide abrasives: such as brown, white corundum, etc. 0 carbide abrasives: such as black and green silicon carbide. 1.4.2 by a binding agent <1. Inorganic binder abrasives: There are ceramic binders and rhombohedral binder abrasives. <2. Organic binder abrasives: There are resin binders and rubber binder abrasives. 1.4.3 according to the basic shape and method of use There are grinding wheels, oil stone, and tiles, grinding heads, etc. 1.4.4 According to the manufacturing method There are pouring, hot wax injection, pressing abrasives, etc. 1.4.5 by special purpose There is a high-speed grinding wheel, atmospheric hole grinding wheel, grinding steel ball grinding wheel, grinding thread grinding wheel, rice grinding wheel, diamond dressing grinding wheel, honing oil stone, dental grinding wheel and so on. 15 general abrasive use Abrasives are tools used to grind workpieces. In terms of its cutting effect, The abrasive grains on the 230*3*22 sharp cutting off wheel are like countless sharp multi-blade tools, which fully exploit their characteristics during the grinding process: 1 〉 can achieve high processing accuracy (1~2 grade) and better surface roughness <1~0.012 〉 2> can process hardened steel and other high-hard materials; 3 〉The processing allowance is small, which can save a lot of materials; 4> can process complex profiles such as spheres, curved surfaces or other irregular surfaces; 5> Easy to implement automation, automatic line processing, etc. Therefore, abrasive tools are indispensable grinding tools for steel, aerospace, marine, automotive, instrumentation, electronics, measuring tools, cutting tools, bearings, agricultural machinery, electrical machinery, precision machinery, and other mechanical processing industries.

In recent years, the development of society is achievable. Our social level is constantly developing, and people's lives are becoming more and higher. Therefore, all industries in the society are developing better and better. Then the development of the machinery industry, more mechanical products need to be processed, each product processing needs to be formed by cutting sheet, the grinding wheel cutting piece is widely used in the current production, the installation of the 230*3*22 sharp cutting off wheel is directly related to the production process. Security issue, The spark generated when the grinding wheel is working is very large, so it must be noted that it is burnt. Generally, the following matters should be noted when working on the grinding wheel: 1, can not be placed around flammable and explosive materials; 2, do not wear polyester clothing, polyester is a by-product of petroleum, is flammable; 3, do not wear short sleeves but should wear long trousers. The grinding wheel is not rubbed to produce high temperature to burn the contact part, but to generate a sharp angle when rubbing, thereby cutting the hard metal material. Those sparks are only the phenomenon after the angle of interest, not the high temperature generated by friction. Melt the workpiece. Speaking of abrasive tools, I don’t know how much people know about it, but it’s indispensable in our lives. Abrasives are tools for grinding, grinding and polishing. Most of the abrasive tools are made of the abrasive plus binder. Artificial abrasive tools, also used as natural abrasive tools directly processed from the natural mineral rock. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in food processing, paper industry, and ceramics, glass, stone, plastic. , processing of non-metallic materials. The choice of abrasive grain size is mainly related to the surface roughness and productivity of the machined surface. When rough grinding, the grinding allowance is large, and the required surface roughness value is large. Thicker abrasive grains should be used. Because the abrasive grains are thick and the pores are large, The grinding depth can be large, the 125*1*22 EN12413 cutting disc is not easy to block and heat. When grinding, the margin is small, the roughness value is required to be low, and finer abrasive grains can be selected. Generally speaking, the finer the abrasive grains, the surface roughness is ground. The better.
