No Picture
For the grinding wheel cutting piece, I think everyone knows a little. The China cutting disc for metal cutting chip manufacturers come to talk about the storage of the different characteristics of the grinding wheel. In fact, the grinding wheel is the most important type of grinding in grinding. The grinding wheel is a porous body made by adding a binder to the abrasive, pressing, drying and roasting. Due to the different abrasives, binders and manufacturing processes, the characteristics of the grinding wheel are very different, so it has an important impact on the processing quality, productivity and economy of the grinding. The characteristics of the grinding wheel are mainly abrasive, particle size, binder, hardness, Factors such as organization, shape, and size are determined. The notes on the storage of different characteristics of the grinding wheel are as follows: 1. Large or thicker grinding wheels should be placed in an upright, slightly inclined position. 2. Thinner and smaller grinding wheels should be placed flat and the stacking height should not exceed 600mm. 3. Cup type, bowl type, butterfly type wheel are stacked bottom to bottom, the height of stacking should not be too high. 4. The organic binder abrasive should pay attention to moisture and oil-proof contact, otherwise, it will reduce the strength and grinding efficiency of the grinding wheel. 5. Abrasives of resin, rubber, and rhombohedral binder should strictly control the storage time to prevent storage for too long, resulting in a chemical change or aging of the abrasive bond, which causes the bonding force to decrease, affecting the strength and durability of the abrasive tool. For more than one year, these types of abrasive tools must be re-inspected before they can be used. 6. The thin-plate grinding wheel of resin and rubber bonding agent should be stacked on a flat metal plate. The height should not exceed 300mm, and the upper part is pressed with a flat metal plate to prevent warping and deformation. 7. The grinding wheel handling process should be handled gently to prevent vibration, so as to avoid damage. The resin EN12413 cutting discs is transported to the machine tool by special handling tools (or plug-in battery cars). 8. The product certificate or another mark on the abrasive tool should be kept clear and complete.

In the grinding process, the blunt abrasive grains will be slightly broken and large broken under the effect of the thermal shock of grinding force, thus forming a new edge, and may also occur abrasive peeling so that new abrasive grains exposed. This continuous renewal of the abrasive cutting edge is called self-sharpening. In grinding, since the self-sharpening action along the surface of the fast working grinding wheel is roughly the same, there is no change in the surface shape of the grinding wheel, which is significantly different from other cutting methods. In the grinding process, fast working grinding wheel self-sharpening will only occur when the grinding wheel characteristic parameters are chosen properly. When the grinding wheel is too soft, the abrasive particle shedding is too fast, the wear of the grinding wheel is serious, and the shape accuracy is destroyed; when the grinding wheel is too hard, not only the wear surface of the top of the abrasive particle with a larger wear surface will not break and fall off, but also the blockage of the fast working grinding wheel will occur, which will deteriorate the grinding process and deteriorate the grinding quality.

Speaking of customized metal cutting disc, I don't know how much you know. Ultra-thin grinding wheels are of great help to the large machinery industry, such as the cutting of steel pipes. If there is no cutting piece, there is no way to cut them. Therefore, its application is also very much. Ultra-thin grinding wheel belongs to the grinding wheel and is also a kind of grinding tool. The common three processes for producing such a resin grinding wheel cutting piece are as follows. 1. Cold pressing process: the bonding agent used is a wetting agent and a powdery resin. It is usually used as a wetting agent for liquid phenolic resin, furfural, decyl alcohol, cresol, etc. The most used is a liquid phenolic resin. 2. Semi-hot pressing process: the pressing temperature is generally 50-65 ° C. At this pressing temperature, the viscosity of the liquid resin becomes small, and the powdery resin can be well integrated so that the fluidity of the entire resin system is improved. It is easier to fully penetrate the various spaces. Even if the pressure of the press is not too high, it can be molded well, and the holding time does not need to be too long. It is especially suitable for the automatic pressing production line for continuous operation. 3. Hot pressing process: The mixing requirement is different from the cold pressing process. Generally, the dry mixing method is used, or 1% of furfural less than the weight of the abrasive is used as a wetting agent to wet the abrasive, and then mixed with the powdered resin. Now, ultra-thin grinding wheels have been used for cutting stainless steel pipes, capillaries, glass tubes, quartz tubes, automobile exhaust pipes, brake wires, tungsten wires, molybdenum wires, copper wires, and other pipe and filaments. And the slotting of the workpiece has a good effect. What is easy to fall off? What does it mean that the abrasive grains are easy to fall off? Some people may not know much about this. In fact, the hardness of the grinding wheel is low. The hardness of the grinding wheel means that the abrasive grains on the surface of the grinding wheel are from the bonding agent under the action of cutting force. The difficulty of falling off. If the abrasive particles are easy to fall off, the hardness of the abrasive is low; otherwise, the hardness is high. The general principle of grinding wheel hardness selection is: grinding hard materials, soft grinding discs should be selected to keep it better "self-sharpness", improve the service life of grinding discs, reduce grinding force and grinding heat; grinding soft When using materials, the 6 inch es cutting disc should be used, which can keep the sharp edge of the abrasive grain sharper for a long time, which is good for cutting.

The stone crusher refers to a Stone Crushing Equipment with a particle size of more than three millimeters in the discharge, which accounts for more than 50% of the total discharge amount. Broken homework is often divided into coarse, medium and fine crushed according to the size of the feed and discharge. Commonly used sand and gravel equipment are jaw crusher (providing equipment: crusher), impact crusher, impact crusher, compound crusher, single-stage hammer crusher, ring hammer crusher Stone machine, conical crusher, double roller crusher, etc. What types of stone crushers can be divided into: The shovel type stone crusher is a crushing machine that uses two slabs to squeeze and bend materials, and to crush or break various hardness materials. The crushing mechanism is composed of a fixed jaw and a movable jaw. When the two jaws are close to each other, the material is broken, and when the two jaws are separated, the block smaller than the discharge opening is discharged from the bottom. Its crushing action is intermittent. This type of crusher is widely used in mineral processing, building materials, silicates and ceramics due to its simple structure, reliable work and ability to break hard materials. Conical stone crusher is used in gravel machinery for medium or fine broken homework. The average grain size of the middle and fine broken homework is generally higher than that required for the coarse crushing homework. Therefore, a parallel zone must be set at the lower part of the crushing cavity, and at the same time, the rotational speed of the crushing cone must be accelerated so that the material is in the parallel zone. Subject to more than one squeeze. The roller type Quarry crusher is a machine that uses the frictional force of the roll surface to bite the material into the crushing zone and to be crushed by crushing or splitting. When used for coarse crushing or when it is desired to increase the crushing ratio, teeth or grooves are often made on the roll surface to increase the splitting action. Roller crushers are usually divided into single-roll, double-roll and multi-roll crushers according to the number of rolls. They are suitable for coarse, medium or fine crushed coal, limestone, cement clinker and feldspar. The hammer-type stone crusher has the advantages of large crushing ratio, average grain size, less crushing and destruction, and low energy consumption. However, because the hammer head wears faster, it is limited in the application of hard material crushing; in addition, because the purlin is afraid of blockage, it is not suitable for crushing the material with high humidity and clay. This type of crusher is usually used to crush brittle materials below medium hardness such as limestone, shale, coal, gypsum and chalk. The counter-attack type stone crusher is a machine that utilizes the high-speed impact of the plate hammer and the rebound action of the counter-attack plate to cause the material to be crushed by repeated impacts. The hammer is fixed on the high-speed rotating rotor, and several counter-attack plates are arranged at different angles along the crushing chamber.

add to favorites 6 categories of grinding wheel polishing l/mile No $
The main raw material of the resin EN12413 cutting discs is high-quality silicon carbide, which has the advantages of high hardness, self-sharpness, and high efficiency. The grinding wheel can have many types of polishing when it is working. The sharp and durable cutting wheel manufacturers have summarized six types for us. 1) Ultrasonic polishing: The workpiece is placed in the abrasive suspension and placed together in the ultrasonic field, and the abrasive is ground and polished on the surface of the workpiece by the action of ultrasonic waves. Ultrasonic machining has a small macroscopic force and does not cause deformation of the workpiece, but it is difficult to manufacture and install the tooling. Ultrasonic processing can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is applied to stir the solution to dissociate the dissolved products on the surface of the workpiece, and the corrosion or electrolyte near the surface is uniform. The cavitation of the ultrasonic wave in the liquid can also inhibit the corrosion process and facilitate surface illuminating. 2) Fluid polishing: Fluid polishing relies on high-speed flowing liquid and abrasive particles carried by it to wash the surface of the workpiece for polishing. Common methods include abrasive silicon carbide injection processing, liquid jet processing, hydrodynamic grinding, and the like. Hydrodynamic grinding is hydraulically driven to cause the abrasive-carrying liquid medium to flow back and forth across the surface of the workpiece at high speed. The medium is mainly made of a special compound which flows at relatively low pressure and is doped with an abrasive. The abrasive can be a silicon carbide powder of abrasive material. 3) Magnetic grinding and polishing: Magnetic grinding and polishing is the use of magnetic abrasive to form an abrasive brush under the action of a magnetic field to grind the workpiece. This method has high processing efficiency, good quality, easy control of processing conditions and good working conditions. With a suitable abrasive, the surface roughness can reach Ra 0.1 μm. 4) Mechanical polishing: Mechanical polishing is a polishing method that removes the polished convex portion by plastic deformation of the surface of the cutting material to obtain a smooth surface. Generally, oil stone strips, wool wheels, sandpaper, abrasive belts, nylon wheels, etc. are used, For the main parts, special parts such as the surface of the rotary body, auxiliary tools such as a turntable can be used, and the method of super-fine grinding can be used for the surface quality. Ultra-fine grinding and polishing is a special grinding tool made of abrasive. In the polishing liquid containing abrasive, it is pressed against the machined surface to perform high-speed rotary motion. It is relatively high in various polishing methods. This method is often used in optical lens molds. 5) Chemical polishing: Chemical polishing is a process in which a material which is slightly convex on a surface of a chemical medium is preferentially dissolved in a concave portion, thereby obtaining a smooth surface. The main advantage of this method is that it can polish a workpiece with complex shapes without complicated equipment, and can polish many workpieces at the same time with high efficiency. The core issue of chemical polishing is the formulation of the polishing fluid. 6) Electropolishing: The basic principle of electropolishing is the same as chemical polishing, that is, the surface of the material is selectively fused to make the surface smooth. Compared with chemical polishing, the effect of the cathode reaction can be eliminated, and the effect is better. The electrochemical polishing process is divided into macro leveling and micro leveling. The six types summarized by the hot sale cutting wheel are relatively complete, and the conditions, advantages, and disadvantages of the polishing type in our daily application are described in detail, hoping to help the friends who need polishing work to make a suitable choice.

add to favorites Four effective ways to avoid surface burns on the workpiece 6.00 l/mile No $ 6.00
Since the cause of burns is high temperature, the main method of avoiding burns is naturally to reduce the generation of heat and accelerate the heat transfer. That is to say, reducing the action time of grinding heat and heat can avoid high temperature and burn on the surface of the workpiece. In production, the main methods to avoid surface burns on the workpiece of the customized metal cutting disc are: 1. Choose the right grinding wheel: the hardness of the abrasive itself is high and the brittleness is better. Such abrasives are not easily blunt during the grinding process, and the abrasive grains after blunt wear are also easily broken to form a new sharp edge, thereby keeping the abrasive grains from cutting the workpiece, instead of rubbing against the workpiece to avoid grinding. A lot of heat is generated. For example, grinding a hardened steel with a white corundum grinding wheel and grinding a hard alloy with a diamond grinding wheel is not easy to burn the workpiece. 2. The use of resin bond grinding wheel is one of the effective measures to reduce burns. The resin binder burns off under the action of the temperature in the grinding zone, and it is not easy to burn the workpiece. For example, in a vertical flat grinding, a resin bond grinding wheel (or sand tile) is used in a high-gloss grinding process using a resin binder and a graphite fine-grained grinding wheel. 3. The use of loose or atmospheric hole grinding wheels, their "self-sharpness" is good, cutting performance is strong, and heat dissipation conditions are good. At the same time, the grinding wheel is also beneficial to the internal cooling method, which greatly reduces the temperature of the grinding area and reduces the risk of burns. 4. Reduce the hardness of the grinding wheel: it can reduce or avoid the burn of the workpiece. Because the hardness of the grinding wheel is too high, that is, the proportion of the bonding agent is large, and the bonding agent itself has no cutting ability, and only causes friction with the workpiece, so that the workpiece generates a large amount of frictional heat. The 6 inch es cutting disc is made of glass fiber and resin as the reinforced bonding material. It has high tensile strength, impact resistance, and bending strength. It is widely used in the production of ordinary steel, stainless steel metal and non-metal.

The theoretical heat (the standard enthalpy) of Artificial Sand Making Plant Design reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient. The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns. The first were simple shaft kilns, similar in construction to blast furnaces. These are counter-current shaft kilns. Modern variants include regenerative and annular kilns. Output is usually in the range 100-500 tonnes per day.

Counter-current shaft kilns

The fuel is injected part-way up the shaft, producing Stone Crushing Equipment Sale maximum temperature at this point. The fresh feed fed in at the top is first dried then heated to 800C, where de-carbonation begins, and proceeds progressively faster as the temperature rises. Below the burner, the hot lime transfers heat to, and is cooled by, the combustion air. A mechanical grate withdraws the lime at the bottom. A fan draws the gases through the kiln, and the level in the kiln is kept constant by adding feed through an airlock. As with batch kilns, only large, graded stone can be used, in order to ensure uniform gas-flows through the charge. The degree of burning can be adjusted by changing the rate of withdrawal of lime. Heat consumption as low as 4 MJ/kg is possible, but 4,5 to 5 MJ/kg is more typical. Due to temperature peak at the burners up to 1200cin a shaft kiln conditions are ideal to produce medium and hard burned lime.

operation of regenerative shaft kilns

These typically consist of a pair of shafts, operated alternately. Fitst ,when shaft A is the primary and B the secondary shaft, the combustion air is added from the top of shaft A, while fuel somewhat below via burner lances. The flame is top-buttom. The hot gases pass downward, cross to shaft B via the so called channel and pass upward to exhaust of shaft B. At same time in both shafts cooling air is added from the buttom to cool the lime and to make exhaust of gases via the buttom of the kiln impossible via maintaining always a positive pressure. The combustion air and cooling air leave the kiln jointly via exhaust on top of shaft B, preheating the stone. The direction of flow is reversed periodically (typically 5-10 times per hour) shaft A and B changing the role of primary and secondary shaft. The kiln has three zones: preheating zone on the top, butning zone in the middle, and cooling zone close to the buttom. The cycling produces a long burning zone of constant, relatively low temperature (around 950C) that is ideal for the production of high quality soft burned reactive lime. With exhaust gas temperatures as low as 120c and lime temperature at kiln outlet in 80c range the heat loss of the regenerative kiln is minimal , fuel consumption is as low as 3,6 MJ/kg. Due to these features the regenerative kilns are today mainstream technology under conditions of substantial fuel costs. Regenerative kilns are built with 150 to 800 t/day output, 300 to 450 being typical.

The high quality grinding disc has a wide range of applications Due to the characteristics of diamond abrasives, diamond abrasive tools are an ideal tool for grinding hard and brittle materials and hard alloys in grinding process, which not only has high efficiency, high precision, but also good roughness, less abrasive consumption and long service life. Long, but also improve working conditions. Therefore, it is widely used in low-iron content metal and non-metal hard and brittle materials which are difficult to process in ordinary abrasive tools. It is widely used in optical processing, sapphire, watch lens, glasses, glass products, precision ceramics, ferrite, automobile and motorcycle parts, and beauty. , aviation, military, labor cutting tools and other industries. Such as cemented carbide, high alumina porcelain, optical glass, agate gemstones, semiconductor materials, stone and so on. So far only ceramic bond high quality grinding discs can be trimmed on the machine. When grinding with this grinding wheel, there is too much wear and the feed rate is too low. Recently, however, a resin bond grinding grooved grinding disc has been developed which has a high material removal rate and can be trimmed on production equipment.
