The sharpness of the grinding wheel is the main type of grinding tool in the grinding process. The appearance of the grinding wheel has certain advantages, but the grinding wheel has occurred in the event of injury, so the safety performance of the grinding wheel has also received extensive attention. Henan abrasive grinding tool manufacturers Remind that you need to be aware of the following issues when using the grinding wheel. 1. Please check carefully before installing the sharp and durable cutting wheel to confirm whether the cutting wheel has deformation, crack, and collapse. 2. When the flange is too small or the precision is poor, it is easy to damage the cutting wheel, please use it after improvement. 3. When the cutting wheel is marked with the direction of rotation, it must be consistent with the direction of rotation of the machine tool. On the contrary, the cutting is not sharp, it is difficult to play the performance of the cutting wheel. 4. If the cutting wheel that does not match the cut workpiece is used, it is prone to abnormal wear, poor sharpness, abnormal heat, etc. 5. If an abnormality is found during the cutting process, stop immediately. 6. In the sharp and durable cutting wheel rotation, it is strictly forbidden to cut by hand, and it is not allowed to touch the grinding wheel by hand or body. 7. The cutting wheel is strictly prohibited for operations other than grooving or cutting, to avoid abnormalities due to uneven force. 8. When the cutting is not sharp, the grinding wheel should be trimmed and edged. If it continues to be used, it will overheat and overload and the grinding wheel will be damaged.

The circumferential speed of the grinding wheel has a close relationship with the grinding amount of the customized metal cutting disc. Whether the selection of the grinding amount is reasonable is not only related to the production efficiency, but also has a great influence on the surface finish of the workpiece, the processing precision and whether it is burned. Therefore, we need to select large values ​​according to the specific processing conditions and ensure the processing quality, so as to improve the production efficiency. So what is the peripheral speed of the grinding wheel? Henan abrasives manufacturers to answer your questions: 1) For workpiece materials with high hardness and toughness, the peripheral speed of the grinding wheel should be higher. For example, the grinding steel material has a higher speed than the grinding iron. However, for high-strength alloy steel materials, the speed should be lower to avoid the grinding debris sticking to the grinding wheel. On, affecting the grinding effect. 2) Manual feed should be lower than the speed of automatic feed, because the automatic feed is uniform, the wheel load is stable. The rough grinding should be lower than the fine grinding speed. The dry grinding should be lower than the wet grinding speed, because the dry grinding heat condition is poor. 3) The speed of the hard grinding wheel is lower than that of the soft grinding wheel to avoid strong heat generation. 4) The enamel bond grinding wheel has lower dead knot strength than the resin bond or rubber bond grinding wheel, so the circumferential speed is low. When the limit of the circumferential speed of the grinding wheel is not indicated on the grinding wheel, the circumferential speed of the ceramic bond grinding wheel should not exceed 35 m/s, and the circumferential speed of the rubber bond grinding wheel should not exceed 40-50 m/s. In this case, the circumferential speed of the grinding wheel is constant, but in the use of the 6 inch es cutting disc, the wear speed is gradually reduced, and the circumferential speed is decreased. When the circumferential speed is reduced to a certain degree, so that the finish is not required, Must be replaced with a new grinding wheel.
add to favorites Protection Principle Of Galvanized Coil Hot-Dip Galvanized Layer   No  
Why hot dip galvanized steel coil for sale is very popular, why steel sheets are subject to heat by zinc because zinc can form a film with good corrosion resistance on the surface in a corrosive environment. It not only protects the zinc layer itself but also protects the steel base. Therefore, the steel after the heat is passed through the zinc. Greatly extended service life. The service life is related to the coating and the environment in which it is exposed, as evidenced by atmospheric corrosion tests on hot-dip galvanized sheets. Hot-dip galvanized sheets have different corrosion rates in different ambient atmospheres. Theoretically, such corrosion may be carried out in two different ways, namely chemical corrosion and electrochemical corrosion. Chemical eclipse is a direct chemical interaction between the metal and the surrounding plate. For example, dry (absolutely moisture-free) gases and non-conductive liquid media (non-electrolytes), the chemical action on zinc is called typical chemical corrosion. Hot-dip galvanizing is currently showing a dynamic development. Hot tin plating is in the process of being replaced by electroplated tin. The same is hot-dip, so there are different prospects, determined entirely by their use and characteristics. Tinplate is mainly used indoors, such as cans, tea boxes, etc., so it does not require too thick plating. In addition, the tin plate is cathodic protection, and once the iron is dropped, the layer is completely lost in protection. Therefore, like a tin plate, it is often required to be uniform and non-porous and thin, and the characteristics of the electric arc are just to meet these requirements. Galvanized sheets are mainly used outdoors, and their corrosive environment is relatively harsh, so thicker slope layers are required. In addition, the zinc layer belongs to the anode protection, and the layer is not uniform. The problem is not big. The thicker the reservoir layer, the longer the service life, and the characteristics of the hot money zinc can meet these requirements. The electro-galvanized coating is uniform, and it is firmly combined with the right, and the surface of the well is less, but the thickness of the layer is thin. It is only one-fifth to one-seventh of the thickness of the hot-dip zinc layer. If the zinc plating of the electric slope is thickened, not only the power consumption is large, but also the residence time in the electrolyte needs to be increased so that the equipment should be increased accordingly. The layer thickness of the electric zinc is generally up to about 18 g/m, so the use range of the pillow is limited. Moreover, its production cost is high and its production is low. It is seen that the production capacity in the world is only about one-seventh of that of hot zinc. Although the production of electricity by zinc is constantly increasing, it is not a strong enemy of heat development by zinc.
add to favorites Cause of cracking of the cutting piece l/mile No $
No Picture
The rupture of the cutting piece occurs from time to time, and the rupture of the resin EN12413 cutting discs poses a certain threat to people's safety. Then why is this happening? First, the rupture when the machine is idling: the cutting piece is idling for one minute when it is used in the cutting table. There are two main factors in the process of rupture. One is that the cutting piece is inferior. The product itself does not reach the cutting line speed. In addition, the cutting piece aperture And the cutting table shaft is not equipped, there is a large stress during assembly. Second, the cutting piece breaks during use: we often see that the cutting piece is normal when it is used. When the cutting is performed in the normal 1/3 state, the grinding wheel is broken. The analysis may be due to the following reasons: the flatness of the cutting piece is poor, cutting The sheet structure is uneven, the hardness of the cutting piece is high, and the resin of the cutting sheet lacks toughness. 1. When the flatness of the cutting piece is poor, the cutting surface is curved. As the cutting depth increases, the cutting piece is subjected to lateral stress increase. When the round trip is repeated, the grinding wheel will be cracked and cause "soft film". Cracked. 2. When the cutting piece is unevenly organized, with the torque force, thermal stress, tremor and other factors of the cutting process, the stress will accumulate in the weak tissue, leading to cracking. 3. When the hardness of the cutting piece is high, the radial torque force of the cutting piece will increase. Since the thickness of the China cutting disc for metal is usually less than 4 mm, the cutting piece will be broken. 4. When the cutting piece resin lacks toughness, since the grinding wheel piece is always in a negative pressure state during the cutting process, lateral stress is inevitably generated, and when the cutting piece cannot resist the lateral force, the grinding wheel piece is broken.

Metal grinding tools should be a device that everyone is familiar with in our lives. Of course, it plays an important role in life, but many users don't know the principle. So today, Aurora abrasives manufacturers describe China abrasive tools for metal . Information about the principle of the tool equipment. With the continuous improvement of the automation degree of grinding tools, the structure of machine tools has become more and more complicated, and the technical requirements for equipment management and operators have become higher and higher. Therefore, many resin grinding wheel enterprises have experienced the shortage of senior technicians. Maintenance technology can't keep up. Moreover, with the improvement of raw material performance, the increase of labor costs, the further development of market environment and the mutual merger and expansion of large and medium-sized companies, fully automatic resin grinding wheel equipment will also be widely used. When it is used, the company faces more sophisticated production equipment. If it can't deal with the problem quickly, it will have a bad impact on the tight and rapid production environment. Especially in the flow mode, if the technician can recover the machine one minute earlier. Production is a kind of benefit for the enterprise. We use professional and power to protect our production equipment. Equipment management personnel - the company's steel guards. Many factory equipment management personnel will complain about the heavy workload, management is a false name, just A maintenance worker. The reason for the company system is actually the responsibility of the maintenance personnel. Facility managers have to wait until the machine is broken before going to work, always passive repair, do not know how to take the initiative to prevent, it can only be called a maintenance man, can not be called device management.

Thefree sample cutting disc is a commonly used cutting device and is popular among users in the market. However, most people do not know much about its basic composition and structure. Let me introduce you to the free sample cutting disc today. Basic analysis. The cutting disc is a fixed abrasive which is fixed by a bonding agent into a certain shape and has a certain strength. It is generally composed of an abrasive, a bonding agent and a pore. These three parts are often called the three elements of the fixed abrasive. According to the different classification of bonding agents, common ceramic grinding wheel, resin grinding wheel, rubber grinding wheel. The cutting discs are made of high-strength resin and special abrasives, which allow large linear speeds, all exceeding 50 m / s, which are not easy to be brittle. The cutting is sharp, the cutting heat is extremely small, and the heat of the cutting disc sample is shallow, thus limiting Reduce the interference. The cutting disc is widely used in machinery, automobile, ship, metallurgy, chemical industry, etc. It can also be used in the decoration and equipment repair of modern house and factory.

Because of its high efficiency, convenience, economy, and other unique properties, the flat abrasive cutting disc has been widely used in many industries, but many people do not have a clear understanding of the specific properties of the cutting piece and the use of different cutting pieces. The grinding wheel cutting chip manufacturers are based on Years of experience to share with you the correct choice and use of the cutting piece: Cutting blades can be divided into cutting and grinding. Most of the cutting machines are fixed mobile. The power of the machine is divided into high power (>5.5KW) and low power (<3KW). The cutting speed also has high speed. Cutting (>80m / s) and ordinary cutting. In addition, cutting materials are varied, such as stainless steel, titanium alloy, ordinary steel, vicious metal, high carbon steel, non-metal, etc. The requirements are different, so it is important to choose a reasonable cutting piece. Ordinary cutting machines usually refer to fixed cutting machines, cutting machines with power <3KW and rotation speed of 2900 rpm. Ordinary cutting machines usually cut workpieces with a diameter less than 50mm. However, due to the small cutting power in order to reduce the radial frictional resistance, this When we usually choose a cutting piece with a thickness of 3.2mm, the cutting piece is thinner and has a certain elasticity, and it will feel sharper when cutting. Sanxiong Abrasives Co., Ltd. changes the surface contact into point contact in order to reduce the lateral frictional resistance. And the formulation system incorporates a lubricant, which can greatly reduce the frictional heat generated during cutting and improve the durability and sharpness of the cutting blade. High-power cutting machines usually use a cutting power of more than 5.5 kW, a speed of 2800 rpm, and a large diameter of the cutting workpiece. Because the torque is large during cutting, the damage to the hot sale 9" cutting off wheel is also large, so the cutting piece is required. To have a certain rigidity, we usually use a 3.8mm thick cutting piece. At the same time, due to the large cutting diameter, the cutting piece will be increased in resistance, and the cutting surface will have a high temperature. Therefore, it is very important to reduce the cutting temperature. If conditions are met, water should be added for cooling when cutting. The experiment proves that if the water is cooled during cutting, the durability of the cutting piece can be improved by 1.5-2 times.

With the development of the machinery industry, more mechanical products need to be processed, and each product processing needs to be formed by customized metal cutting disc. The grinding wheel cutting sheets are widely used in the current production. The installation of the grinding wheel cutting sheets is directly related to the production process. In the safety issue, we need special attention. Now Henan abrasives are simple to say that the lower grinding wheel needs to be handled during use: 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. The grinding wheel piece we just said is that when the friction is generated, the sharp angle is generated. The hard metal material is cut off, and the grinding wheel cutting piece is very sharp. If the operation is improper, it is very easy to cause an accident, so we need to pay attention to the operation. The following points: 1. Before driving, you must carefully check whether the operating handles or buttons are in the correct position. The various movements of the grinding machine are normal. 2. Before using the new grinding wheel, first idle for 5 minutes. After confirming that the operation is normal, first fix the outer and outer surfaces of the grinding wheel, then remove it together with the flange, and then perform a static balance. 3. When grinding, the workpiece grinding wheel should be fed again under normal running condition (the feed cannot be too strong); also, it must be retracted before parking. 4. The operator should wear full-length overalls and wear a mask to avoid inhaling dust and grinding liquid mist beads. Female workers should wear work hats and wear protective glasses when trimming the grinding wheel to prevent debris from flying into the eyes. 5. Before stopping the vehicle, the liquid supply system should be cut off, and the 6 inch es cutting disc should be idling for 1-2 minutes to remove the grinding wheel and absorb the grinding fluid.

I believe that the problems that we often discuss after a meal are nothing more than news stories, fashion trends, entertainment gossip, etc. If it is not a participant in the abrasives industry, we can hardly imagine it. What is a grinding wheel cutting piece and what is a grinding machine? So what exactly does this have to do with us? The first thing we should know about cutting piece is that the resin EN12413 cutting discs belongs to the grinding wheel and is made of abrasive and binder resin for ordinary steel. Stainless steel metal and non-metal sheets, which are widely used in the production and cutting of ordinary steel, stainless steel metal and non-metal, so what special classifications and characteristics do we have? Let's take a look! The cutting sheets are mainly classified into fiber resin cutting sheets and diamond cutting sheets according to materials. 1. The resin cutting piece is made of resin as a bonding agent, combined with various materials, and the cutting performance is particularly remarkable for difficult-to-cut materials such as alloy steel and stainless steel. Dry and wet cutting methods make the cutting precision more stable. At the same time, the choice of material and hardness of the cutting piece can greatly improve your cutting efficiency and save your production cost. 2, diamond cutting sheet is a cutting tool, widely used in stone, concrete, prefabricated panels, new and old roads, ceramics and other hard and brittle materials processing. The China cutting disc for metal is mainly composed of two parts; the base body and the cutter head. The base body is the main support part of the bonding cutter head, and the cutter head is the part which is cut during use, the cutter head is continuously consumed in use, and the base body does not, the cutter head can cut The role is because it contains a diamond, which is the current hard material, which rubs the object to be processed in the cutter head. The diamond [1] grain is wrapped in metal inside the cutter head.

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.
