In order to give full play to the role of diamond, it is necessary to increase the holding force of the bonding agent on the diamond and improve the bonding strength of the depressed grinding disc in stock. The single-layer high-temperature brazing super-hard abrasive depressed grinding disc in stock can overcome the shortcomings of the electroplated grinding wheel, and can realize the chemical metallurgical combination between the diamond, the bonding agent and the metal matrix, and has high bonding strength, and only needs to maintain the thickness of the bonding layer in the grinding. 20% to 30% of the height of the grain can firmly hold the abrasive grains in high-load high-speed and high-efficiency grinding, so that the abrasive height of the brazing wheel can reach 70% to 80%, thus increasing the chip space. The grinding wheel is not easy to block, and the use of abrasive is more sufficient. Under the same processing conditions as electroplated grinding wheels, the single-layer high-temperature brazing super-abrasive grinding wheel has lower grinding force, power loss, and lower grinding temperature, which means higher working speed can be achieved, which is 300-500m/s. The above super-high speed grinding has special significance.

In the conventional industry, the polishing technique is a process of cutting the surface of a metal part by means of the rotation of a customized metal cutting disc to which the abrasive adheres. With the development of the industry, grinding technology is also constantly improving. When the traditional cutting piece is polished in stainless steel, the grinding will not deteriorate, but the red part on the surface will be deteriorated. If the original color is restored after polishing, it will not deteriorate, because the deterioration has been worn away. However, in the polishing, our operators should also pay attention to the fact that the intergranular body of the cutting piece will definitely change, that is, the bending or the tube will cause the intergranular body to be misaligned, which is only slight and will not seriously change the material. If there is a phenomenon of sharpening the transition, it will lead to a change in the composition of the tempering. The stainless steel cutting piece contains less than 18% ferritic stainless steel, which has good cutting performance because its structure is slightly brittle and the chips are easily broken. In terms of machinability, these steels are attributed to low carbon martensitic stainless steels. Stainless steel cutting sheets are difficult to cut because they are vicious and have long chips, and these steel grades are similar to cutting austenitic stainless steels. Grinding After the dicing sheet is used, the surface of the diced silicon wafer has a certain degree of damage and deformation, and since the precision of the feeding of the microtome is limited, the thickness of the silicon wafer is dispersed, so that the grinding is necessary after the dicing. Grinding the silicon wafer essentially causes the silicon surface to constantly rub against the abrasive under a certain pressure, and removes the damage layer on the surface of the silicon wafer by mechanical grinding. The measurement is generally about 60P, and the silicon wafer is produced when cutting. About 50 u after injury. By studying the silicon wafer, it is more uniform than the cutting and reaches a predetermined thickness. Therefore, the selection of a suitable motion form and the use of a suitable abrasive can improve the quality of the polishing sheet. In addition to abrasives, a suitable abrasive ratio is also critical. Abrasive size and particle size all affect the surface roughness.

In the grinding wheel, there is split type grinding wheels and disc type grinding wheels. The flat grinding wheel is mainly used for cutting, so it is also called a cutting piece, or a resin EN12413 cutting discs. If it has special requirements, it can also have an ultra-thin cutting piece. The disc type grinding wheel is mainly used for grinding and grinding. Grinding and grinding discs are called grinding discs. Grinding discs are usually thicker and can be more durable and wear resistant in grinding. There are more and more people who use the grinding wheel because the grinding wheel has a very high-cost performance. For saw blades with the same effect, the grinding wheel is not only cheaper but also has other advantages in other aspects. The same price is better than quality, the same quality than price, this famous saying is indeed the truth. Strictly speaking, the grinding wheel is a new type of hardware product. It has only developed in China in recent years. The development process is mixed, so many manufacturers have closed down. The manufacturers that can successfully adhere to it must be very rich. Experience and advanced technical strength. Because of the objective factors such as raw materials and technology, we can't rely solely on theoretical data to complete quality stability and new product development. More practical experience and continuous experimentation are required to ensure product quality and continuously develop new products. The use of phenolic resins as binders for resin wheels is almost universally consistent. Except that the benzene ring resin (an epoxy-modified phenolic resin) is used in the most heavy-duty steel billet grinding wheel, the phenolic resin is basically used, and the formulation and process of the basic resin have been finalized. The binders mentioned here are broadly defined, and in addition to the binder itself (phenolic resin), fillers and additives are included, and the additives are highly varied. The composition of the additive ingredients actually represents what the 6 inch es cutting disc manufacturer has mastered, but the basic bonding agent has not changed much.

Diamond cutting sheet properties First, the diamond cutting piece has high grinding efficiency, and the cutting piece consumes relatively slowly. The China cutting disc for metal has a certain elasticity, which is beneficial to improve the roughness of the surface of the workpiece and is mainly used for the processes of fine grinding, semi-finishing, knife grinding and polishing. Moreover, the diamond cutting piece has good self-sharpness, and the heat generation during grinding is small, which is not easy to block, and the work burn phenomenon occurs during grinding; The resin bond diamond cutting piece of the diamond cutting piece is low-temperature curing, the production cycle is short, the equipment and the supply process are relatively simple, and the cutting piece of the complex surface is easy to be formed because of the fluidity of the resin. It can be selected according to the product model (parallel cutting piece, parallel arc cutting piece, double-sided concave cutting piece, double bevel cutting piece, bowl type cutting piece). Their use: parallel cutting piece: mainly used for cylindrical grinding and edge machining of cemented carbide; parallel arc cutting piece: mainly used for forming grinding of hard alloy and forming grinding of circular arc surface. The above is a brief introduction to the main features of the diamond cutting blade introduction process Cutting sheet characteristics The characteristics of the cut piece include six elements of abrasive grain, particle size, binder, hardness, shape, and size. Common abrasive grains are corundum and silicon carbide. Corundum is suitable for grinding steel and general tools. Black silicon carbide is used for grinding cast iron parts, and green silicon carbide is used for grinding hard alloys. The size of the abrasive particles is expressed in terms of particle size. The larger the particle size number, the smaller the particle size. Coarse particles are used for roughing and fine particles are used for finishing. The binder for the partial abrasive grains is a ceramic binder, a resin binder, a rubber binder, a metal binder, etc., and a ceramic binder is commonly used. The hardness of the cut piece refers to the difficulty of peeling off the abrasive grains at any point on the surface of the cut piece under the action of an external force. Softer cutting discs should be used for grinding harder materials, and harder cutting materials should be used for grinding softer materials. The harder the abrasive grains on the cut piece, the higher the hardness of the cut piece.

What are the finishing steps? 1. The hand grinder table is fed longitudinally to the hand wheel to bring the diamond close to the end face of the slice. 2. Install the grinding section on the round hole of the grinding wheel dresser perpendicular to the axis, adjust the position of the round bar of the slice dresser, make the diamond tip lower than the center of the polishing plate 1-2mm, and fasten the bracket. 3. After the diamond is in contact with the end face of the slice, the longitudinal feed of the table is stopped, and the hand slicer is fed laterally to the hand wheel to reciprocate the diamond back and forth at the end face of the slice. After multiple feeding and trimming, the end surface of the slice is ground into a concave plane, and the edge of the slice transmission line is left with a clip H=3 mm. Pay attention to the correction of the polished sheet: 1. Pay attention to the rigidity of the diamond rod to prevent the diamond from vibrating during correction. 2. When the correction is made, the manual feed of the table should be slow, and pay attention to the width of the control clip. 3. Generally, the end face of the grinding wheel should be trimmed first, and then the circumferential surface of the grinding wheel should be trimmed.

The ZENITH1214 counter-type sand making machine is driven by a motor with a power of 132 kW. The hammer in the crushing chamber breaks the stone entering from the upper inlet by the rotational force. The counter-operating sand making machine is provided with a warning indicator for the operation of the machine. If the rotating part of the counter-type sand making machine motor is unbalanced, it causes the entire motor to vibrate when rotated. Vibration causes damage to the bearings, the feet and the motor itself. In order to eliminate the vibration, the rotating part should be balanced. The balance is divided into static balance on the prism and balance of the balance of the part when rotating. The centrifugal force generated by the rotation of the rotor of the counter-type sand making machine motor is large, which will generate pressure on the bearing and cause vibration of the motor. Such an imbalance can be eliminated by static equilibrium on the prism. The journal of the rotor's bearing is placed on a carefully calibrated horizontal prism, which of course is the heavy half that is turned downwards. Put such a heavy lead block in the special groove above, so that the prism of the rotor can stay in any position. After the balance is good, the lead block is usually replaced by the same heavy steel block, which can be safely welded to the rotor or nailed to the rotor.
