add to favorites What is a high quality 9'' grinding wheel? How to use it? Pc  
There are three main types of high quality 9'' grinding wheel: one is ordinary abrasives, including corundum series and silicon carbide, resin abrasives, ceramic abrasives, etc.; the second is coated abrasives, including abrasive cloth, sandpaper, abrasive belt, etc.; Hard materials, mainly diamond grinding wheels, cubic boron nitride and products. Grinding is an irreplaceable and gradual expansion of machining methods in machining. Analysis of high quality 9'' grinding wheels, after the world entered the new century, grinding processing is still ranked third in the popular machining method. Although hard turning has replaced many grinding processes, due to advances in bonding technology and the use of advanced abrasives, diamond grinding discs remain an important part of the machining process. Grinding is material-driven today, and diamond grinding wheels may be difficult to compete with conventional machining materials for milling, planning and turning, but when it comes to a new generation of materials such as ceramics, cermets, composites, reinforcement Materials, and ultra-high temperature alloys do not have to compete. These materials can only be ground with diamond grinding wheels. The high quality 9'' grinding wheel use conditions: 1. The cutting line speed of the grinding wheel must be greater than 80 m / s. 2. The grinding wheel must be cooled with water when cutting. The cooling water flow is not less than 2.4 liters/min. 3. The new grinding wheel must be trimmed with a special correction plate before use. 4. The cutting depth of the high quality 9'' grinding wheel is determined according to the thickness of the grinding wheel and the cutting material. Generally, the large cutting depth is within 3 mm. 5. When selecting the grinding wheel, in order to ensure a good cutting effect, the grinding wheel with the corresponding abrasive grain size should be selected according to the different cutting materials. 6. The normal cutting speed of the high quality 9'' grinding wheel (the moving speed of the object to be cut) is determined according to the requirements of the cutting material and the cutting precision, and is generally within 0.5-200 mm/sec.

No Picture

In the stone grinding production line or stone grinding plant, to improve the technical efficiency means much for the improvement of ore beneficiation indicators. So how can we improve the technical efficiency of the SBM grinding plant? The answer is to adopt the closed circuit grinding technological process.

The reasonable grinding flow means that mineral grains should be discharged quickly from the grinder once they are ground and separated. For the existing stone grinders, its very difficult to realize the material grain gradation. Therefore, we usually adopt the classifier or fine screener to gain the qualified granularity grade and those coarse material grains will return to the grinding machine again. This process is called sand return.

In the closed circuit grinding flow, the grinder will add returning sand to the new materials. When more materials pass through the grinding machine, the grinder will run faster and the grinding time will be shortened. The closed circuit grinding process requires the unqualified materials moves into and out of the grinding machine again and again till they become qualified ones.

With a large amount of coarse sand fed into the grinder, the closed circuit grinding flow increases the coarse fraction content of the feeding materials. Besides, the proper sand return will remove the vibration of the new materials and bad influence on the granularity of minerals.

add to favorites Method for cutting grinding wheel by diamond grinding wheel Pc  

Using diamond abrasive as raw material, respectively, using metal powder, resin powder, ceramics and electroplated metal as bonding agent, the circular fixed abrasive with central through hole is called diamond grinding wheel.

First, the grinding wheel is easy to collapse when cutting in and out: When cutting the thin flat cutting disc with a tool with a large main angle, the cutting edge is easy to collapse. In order to solve this problem, a circular blade is used to change the main yaw angle, so that the cutting and cutting are smooth. When the feed amount is 1 to 1.5 mm, no chipping occurs.

Second, the chips are in powder form: the chips of the cutting wheel are powdery, and the form of tool wear is the flank wear, which mainly bears the wear of the diamond wheel abrasive.

Third, the cutting force and cutting temperature is low: the diamond composite sheet has a high thermal conductivity, 1.5 to 9 times that of the cemented carbide, and 2 to 6 times that of the copper, so that the temperature in the cutting zone is quickly transmitted. Therefore, the temperature of cutting a resin bond or a ceramic bond wheel with a diamond compact tool is many times lower than that of a cut metal.

4. With the traditional turning tools, the diamond composite sheet has almost no dust flying during the turning process, and the noise is effectively reduced. The working environment of the diamond grinding wheel is further improved, which is beneficial to the physical and mental health of the employees.

(1) Adhesive: This adhesive is different from the adhesive for producing a nonwoven felt, the former being an emulsion type adhesive and the latter being a solvent binder. In order to make the abrasive and the fiber firmly bond, and the heat generated in the polishing process, the surface of the polishing wheel is as high as 150~180 °C, so in addition to good bonding ability, it must be It has high heat resistance. At present, modified phenolphthalein resin, epoxy resin and polyurethane resin are generally used in foreign countries.

(2) Sticking sand: Generally completed on a special finishing equipment. In order to ensure the uniformity of the abrasive on the product, the abrasive application method is particularly important. At present, the dusting method is generally adopted. standard cut off wheel for metalThe structure is a hopper with abrasive material on the top. The hopper is equipped with a discharge roller with elastic card cloth. The discharge roller rotates, and the abrasive falls evenly into the clothing, on the side of the discharge roller. A vibrator with a wire brush is attached, and the abrasive falling into the card clothing is peeled off by vibration and falls onto the non-woven mat. Another method is sprayed onto the non-woven felt by a spray gun, but the uniformity of the abrasive is difficult to ensure, and the abrasive wears on the nozzle. After the abrasive is dusted or sandblasted, the adhesive is sprayed to make the abrasive and the fiber firmly adhered. The knot finally forms a grinding wheel of practical value.

Finally, the grinding wheel is reworked into various types of polishing wheels, which can be divided into four types: shot type, laminated type, pleated type and attached type. Shot type: Cut the sand felt into long squares of the required size. Arranged radially around the wheel core. The inner ring is bonded with an thin flat cutting discand its density is increased from the outside to the inside.

Laminated type: The sand felt is cut into layers of the required size, and the product is laminated and compacted, and the density is uniform inside and outside. Pleated type: The sand felt is cut into long squares of the required size, folded into a circular ring and fixed with a hexagonal steel buckle.

Axis type: Cut the sand felt into long squares of the required size and arrange them radially around the wheel core and insert them into the center shaft. The sand felt has better precision on the working surface than the first and second grades of the fabric, the surface is flat, the wear is small, and the falling sand is small, which is suitable for the mass production of mechanization; the disadvantage is that the abrasive and the fiber are only bonded by the adhesive, bonding The point is small and there is some abrasive falling off.

add to favorites New thinking of forming grinding wheel Pc  

The emergence of new abrasive new binders continues to improve the processing efficiency and quality of thin flat cutting discs . In addition to micro-crushed abrasive grains, such as SPW, a new abrasive that combines single and multiple crystals, this high performance cutting disc also achieves very good results in the grinding of iron-based materials, except for the large resistance to grinding. In addition to the reduction in cutting force, the reduction in the dressing interval also increases the production efficiency. The HW mixed abrasive is a new breakthrough in the grinding wheel manufacturing technology. Since the different abrasive grain characteristics enhance the self-sharpening effect of the grinding wheel, it has exerted an unprecedented effect in the field of forming and grinding.

The lifting agent of the bonding agent is the key to the self-sharpening effect of the grinding wheel, and is also the main determinant of the hardness of the grinding wheel. In terms of forming and polishing, in addition to balancing the cutting force and the shape retaining force, if the heat dissipation and the grinding ratio can be further improved, the polishing efficiency will be greatly improved. With a unique technology, the amount of binder is reduced, and the grinding ratio is greatly increased. The reduced binder is also equivalent to the space for the pores, which increases the space for heat dissipation and reduces the chance of clogging.

The choice of the forming grinding wheel is not as high as the hardness, and it is necessary to avoid the blind spot of the grinding wheel hardness. In fact, more attention should be paid to the basic performance of the grinding wheel such as cutting force, uniform organization and heat dissipation, so that the most suitable product can be selected.

Molding and grinding refers to a method in which a grinding wheel having a certain shape and a workpiece are moved relative to each other, or a forming grinding wheel having a predetermined shape is used, and a grinding processing method by the same turning grinding process is used.

Molding and grinding is widely used in various types of cutting tools, mold parts and stencils. The grinding wheel plays a major role in the transformation. Therefore, the performance of the grinding wheel has a very important influence on the quality and efficiency of the forming grinding.

There are three main requirements for formingthin abrasive cutting disc for metal :

1 shape retention:

Since it is a form grinding, the most important thing is naturally the shape retention ability of the grinding wheel! Good shape retention ensures precision after grinding, while reducing dressing frequency and increasing machining efficiency!

2 surface roughness after grinding

Many molded and finished products are used to move parts to each other. Therefore, good surface roughness reduces the resistance to actuation and increases product life.

3 easy to trim

If the shape retention is good, but it is not easy to trim, it will also reduce the processing efficiency.

Mirror surface refers to a description of the good roughness that can be obtained after mechanical grinding. Just like a mirror, it is shiny and smooth, and it can be clearly called out the metal surface of the object.

Mirror surface grinding generally uses high-quality grinding wheels to achieve excellent surface roughness through precise grinding, while at the same time taking into account the good dimensional accuracy of the knife; the purpose is to effectively improve the mechanical life, reduce the cutting resistance, and in order to obtain a smooth finished product. Molds, etc. Usually the workpieces that are mirror-polished are mostly molds or workpieces that require friction to act on each other. Therefore, to achieve mirror polishing, high performance cutting discs are required. To achieve high performance cutting blades, the following requirements must be met:

Wear resistance: The rougher the surface, the smaller the contact area, the greater the pressure per unit area and the easier it is to damage.

Stable: uneven, unstable, as if driving on uneven roads.

Corrosion resistance: Roughness can easily corrode corrosive gases or liquids from the valleys, causing corrosion of the surface of the grinding wheel.

Anti-fatigue: When fatigue testing is concentrated at a certain point or part, it will amplify the fatigue strength of the grinding wheel.

Sealing: Roughness prevents parts from being tightly bonded, and gas and liquid penetrate through the gaps in contact with the surface of the grinding wheel.

Mirror surface grinding is a kind of precision grinding. The ground material can be placed on the grinding disc, the grinding wheel rotates, the correction wheel drives the workpiece to rotate, the gravity is pressed to press the workpiece, and the workpiece and the grinding disc are relatively operated to rub. Grinding and polishing purposes. The grinding disc dressing mechanism adopts the hydraulic suspension guide rail to reciprocate back and forth, and the diamond shaving cutter precisely trims the grinding surface of the grinding disc, so that the grinding disc obtains an ideal plane effect.

The mechanical processing methods for obtaining mirrors are: material removal method, no cutting method: the material removal methods mainly include: grinding, grinding, polishing, and electric spark. The material removal method must have a large amount of equipment investment; skilled and experienced technical workers; expensive grinding wheels and other prerequisites, mirror grinding still requires cost considerations without special needs.
