1. CBN cutting disc and SDC cutting disc are trimmed with copper blocks. This kind of repairing method is like grinding the workpiece. Generally, it can be rubbed onto the copper block without rubbing (0.05~0.1). The thickness of the cutting disc can be observed to the copper block. (Water should be added when the cutting disc is trimmed). 2. Trim the customized metal cutting disc with diamonds. Diamond repairing knives are single-point and multi-point, and we usually use single-point. Selection of single-point diamond repairing knives: It can be divided into three types: rough, medium and fine diamonds. Rough diamonds are generally used when grinding the outer frame. (1), repair the bottom of the cutting disc: put the diamond seat on the clean platform, magnetize the cutting disc to the upper part of the diamond, the horizontal view of the eye, the smaller the gap between the cutting disc and the diamond, the better, when two After the contact, each time the knife is 0.02~0.1mm, the Y-axis is trimmed before and after (Z-axis is not moving). When roughing, the Y-axis can be shaken faster. When the cutting disc is very thin, the X-axis lower knife should be Less (0.001~0.003mm), while the Y-axis shaking speed should be slowed down, you can walk a few times. After the cutting disc is repaired, you can feel it by hand. Use your thumb to place the cutting disc cover in the lower right corner of the cutting disc cover, and then gently touch the cutting disc surface with your index or middle finger to feel its thickness. (2) Repair the side of the cutting disc: Place the diamond seat on the platform, magnetize it, and cut the disc to the lower part of the side of the diamond. Slowly shake the Y-axis (front and rear direction) to perform side-to-side knives, then digitally return to zero, then shake. The Z-axis handle moves left and right, and the Y-axis feed is small. It can be seen at 0.02~0.1 each time. At the same time, it should be noted that the height of the side surface of the trimming disc can be larger than the required grinding step to reduce the unnecessary waste of the cutting disc. The same is true when trimming the groove cutting disc. 3. Trimming of the forming cutting disc: the cutting disc should be modified when grooving. When the width of the cutting disc is less, the side of the cutting disc is trimmed as in the second point, and the right side is made of diamond in a single point. When trimming the other side, use the cutting disc centimeter to measure the sand width. When approaching the required size, slice it for trial cutting to prevent the sand width from being too large (because the cutting disc is in operation when the machine spindle motion is not in the same horizontal circle) The width of the cutting disc will be slightly larger than the width of the cutting disc. When the width of the cutting disc is wider than the required groove, and the remaining material is more, the roughing diamond is used for the side trimming with the repair method, that is, the Y-axis is 0.05 mm, and the X-axis is raised. 0.1mm high, finishing with medium or fine diamonds for finishing

While continuing to maintain the rapid growth of the industrial economy, how to reduce or avoid further damage to the environment has become a topic of common concern to the whole society, and green manufacturing has naturally attracted more attention.
The concept of green manufacturing has been proposed for many years. Especially in foreign countries, China cut off disc green manufacturing has been widely regarded as an important means to achieve sustainable development of the manufacturing industry. Some mature green cutting technologies have also been widely promoted and applied.
In China, while manufacturing prosperity has contributed to economic growth, resource waste and environmental pollution have followed, and the consequences have begun to emerge. Now, while continuing to maintain the rapid growth of the industrial economy, how to reduce or avoid further damage to the environment has become a topic of common concern to the whole society. Green manufacturing has naturally attracted more people's attention.
The general trend of energy saving and emission reduction
According to statistics, 70% of environmental pollutants come from manufacturing. While modern manufacturing has brought unprecedented material civilization to mankind, it has also brought more wastes such as waste gas, waste residue and waste liquid to society.
From a certain perspective, the impact of the industrial manufacturing sector under the general trend of energy conservation and emission reduction is obviously the biggest. Such a large pressure is passed on to the industrial manufacturing enterprises themselves, which is unrealistic by simply limiting the number of enterprises and affecting normal production. After all, the goal of achieving energy conservation and emission reduction at the expense of the number and scale of industrial manufacturing companies can only solve the temporary itch and cannot solve the problem fundamentally.
Then to find a solution from the manufacturing process, green cutting technology as a sustainable manufacturing model has become one of the choices of manufacturing companies.
Traditional manufacturing models have a big impact on the environment
The reason why the traditional manufacturing mode can not meet the requirements of energy saving and emission reduction is because the cutting fluid is used in a large amount in the processing process, which brings harm to the environment and the human body itself.
In the field of machining, waste liquids produced using cutting fluids are the main contaminant products. Until now, traditional metal cutting still relies heavily on wet cutting of cutting fluids.
The use of cutting fluid can achieve lubrication, cooling, cleaning, auxiliary chip removal and rust prevention performance, and has a significant effect on improving cutting quality and efficiency, reducing tool wear and the like. The cutting fluid has developed to the present day, and it is widely used in the mechanical processing industry, and it is widely used, and it has become a wide variety of industrial products with a wide range of products.
However, the use of cutting fluids also poses a hazard to the environment and human health. If the waste liquid of the cutting fluid is improperly treated, it will cause serious pollution to water resources, and its biodegradability is poor, and it stays in water and soil for a long time. Even with the strictly treated waste liquid, long-term accumulation can cause pollution, and the toxic chemical components remaining on the chips can also pollute the air.
Oil mist generated during the use of cutting fluid and irritating odors may cause harm to the operator's respiratory system. Long-term exposure to chemicals added to it can cause cancer, so people who have been exposed to poor cutting fluid for a long time are prone to respiratory diseases.
Obviously, the traditional manufacturing mode can not bear the requirements of green environmental protection, and green cutting without using cutting fluid becomes an inevitable choice.

Diamond cutting discs are the most widely used processing tools in grinding technology. Diamond cutting discs according to different bonding agents can be generally divided into resin bonding diamond cutting discs, ceramic bonding diamond cutting discs and metal bonding resin EN12413 cutting discs. Resin bond diamond cutting discs mostly use thermosetting resin, which has the advantages of low curing temperature and relatively simple preparation. It is mainly used for sharpening tool measuring tools, grinding holes, cylindrical grinding and surface grinding. The metal bond diamond cutting disc has strong bonding strength and good toughness and can withstand large loads. It has been applied in the fields of profile grinding, precision and ultra-precision grinding of complex profiles of brittle and hard materials. Ceramic bond diamond cutting disc has high modulus of elasticity and low fracture toughness. Its bonding strength is higher than that of resin bond diamond cutting disc. Its self-sharpness is superior to metal bond diamond cutting disc, which is widely used in processing. Composite sheets, hard alloys, glass, ceramics and other materials. This paper aims to make a brief review of the research work on resin bond diamond cutting disc, ceramic bond diamond cutting disc and metal bond diamond sand raft in recent years. Although the research on resin bond diamond cutting disc, ceramic bond diamond cutting disc and metal bond diamond cutting disc has made progress in recent years, these three types of cutting discs are random due to the shape of the abrasive grains and their distribution. Sexuality, resulting in high ratio of normal force to tangential force during grinding, high grinding specific energy, high grinding temperature, high requirements on the rigidity of the grinding machine, and the abrasive particles are only mechanically embedded and embedded in the bonding agent layer. The holding force is not large, the abrasive grains are easy to fall off during the grinding process, especially the super-abrasive cutting disc has low utilization rate of abrasive grains, resulting in a large amount of waste of resources; at the same time, in order to ensure the effective embedding of the binder layer by the binder layer, grinding The granules generally have a low exposure height and a small space for chipping. The clogging of the swarf is easy to occur during the processing, and the cutting disc needs to be regularly trimmed and sharpened, thereby affecting the processing quality and the grinding productivity. Therefore, how to improve the process, combine the advantages of ceramic bond, metal bond and resin bond, and develop a new type of diamond cutting disk is an urgent need of modern processing industry.

add to favorites Grinding wheel five characteristics -abrasive   No  

Abrasives are generally sharp, hard materials used to grind softer surfaces. Abrasives are available in two categories: natural abrasives and synthetic abrasives. According to the hardness classification, there are two categories of super hard abrasives and ordinary abrasives. Abrasives range from softer household detergents, gem abrasives to the hardest material diamonds. Abrasives are essential for making every precision product. Many natural abrasives have been replaced by artificial abrasives. In addition to diamond, the performance of natural abrasives is not stable, but it still has its value. Diamond is the hardest abrasive, mainly in South Africa, accounting for 95% of the world's total production, followed by Brazil, Australia, Guyana and Venezuela. Industrial diamonds range from off-white to black.China supply 7" cut off disc After milling, they can be used to make grinding wheels, abrasive belts, polishing wheels and abrasive powders.

Since the 1970s, artificial abrasives have been produced in large quantities, the most important of which are tantalum carbide and alumina. Carbide is commonly known as silicon carbide. It is prepared by mixing pure vermiculite with coke and adding a small amount of wood chips, then placing it in an electric furnace and baking at 2,200-2,480 °C for about 36 hours. Alumina is commonly known as corundum. It is commonly used in the industry to heat and melt aluminum bauxite. It is used as a heat-sensitive metal abrasive in black and white, and it is used to process castings and steel. Synthetic diamond wheels are the hardest abrasives and are necessary for the sharpening of carbide tools. Synthetic diamonds can also be made into tools of various shapes and sizes for cutting glass and ceramics. Boron carbide has a higher hardness than tantalum carbide and is not suitable for making grinding wheels. It can be used to replace expensive diamonds when polishing hard materials. Cubic boron carbide has twice the hardness of tantalum carbide and 2.5 times that of alumina, and it is effective to grind certain tool steels.

One of the important properties of an abrasive is its hardness, which must be harder than the material to be processed. The Mohs hardness tester is commonly used to determine the hardness of various abrasives. Another important property of abrasives is toughness or volume strength. The mixing amount, purity, particle size, and crystal structure of the raw materials can be changed to control this property to suit various applications.

For the manufacture of abrasive products, all raw materials need to be crushed and screened except for powdered talc and iron oxide. The screening particle size should be 4 to 900, that is, the diameter is about 6 mm (millimeter) to 6 μm (1 mm in millimeters). One) or finer. The grinding wheel is the most important abrasive product. It is mixed by abrasive and binder in a certain proportion, sintered by compression molding, and finally must be shaped, balanced and overspeed tested. Abrasive cloth and sandpaper are another kind of abrasive products with a large output. They are bonded to the base material (cloth or paper) by abrasive grains and dried to cut into different specifications. Others are powder or granular abrasives. After screening, they need to be processed by certain processes, such as grinding or polishing abrasives, usually with mineral grease or wax to meet the needs of different working conditions.

4 inches China grinding disc factory describes how to prevent abrasive particles from falling off In the grinding process, the grinding machine basically carries the whole grinding process with a single layer of abrasive. The abrasive grains wear or fall off, and no backup abrasive grains continue to grind, so a limited number of abrasive grains are used for this layer. It is particularly important. How to prevent the shedding of abrasive grains and improve the grinding effect of each particle is an important topic for the research and development of abrasive tools researchers and manufacturers. At present, the following methods are adopted: calcination treatment and alkali treatment. Treatment of coated metal salts. Treatment of coated ceramics. Treatment of coated resin. Treatment with silane. The following 4 inches China grinding disc factory mainly introduces alkali treatment: The abrasive is immersed in a 2% NaOH solution for about 30 minutes, then cleaned and dried. It can be used after drying. The alkali has a certain corrosive ability to the abrasive, thereby increasing the roughness of the abrasive surface and improving the capillary action of the abrasive surface. It is beneficial to the bonding effect between the abrasive and the binder so that the abrasive grains are not easily detached from the surface of the abrasive tool, thereby improving the grinding effect and durability of the abrasive tool. Since the alkali has a certain etching effect on the alumina, this The method is better for the abrasive effect of the corundum series.

Pressure should be applied gradually during grinding to prevent the cutting piece from being impacted and to prevent the cutting piece from bursting. 5. The end of the work grinding should be kept at 20 mm or more from the hand end. 6. The amount of grinding should be appropriate for each grinding to prevent accidents caused by the workpiece running with the cutting piece. 7. When grinding for a long time, cold water should be provided next to the cutting machine to prevent heat and burns when the workpiece is ground. 8. Steel parts with strong fractures cannot be ground on the cutting piece to prevent the workpiece from rupturing. 9. The workpiece should not be ground perpendicular to the upper plane of the cutting piece, that is, the workpiece cannot be polished on the side of the cutting piece. 10. Grinding workpieces should be less than 500 mm in length. For workpieces over 500 mm, other grinding tools, such as angle grinders, should be used for grinding. 11. In the cutting machine used, the difference between the diameters of the two cutting pieces is not more than 20%. 12. Turn off the power immediately after each work is completed. other request: 1. In addition to replacing the cutting piece and repairing and dismantling, the cutting machine protective cover is strictly prohibited to be removed to ensure safety. 2. When the diameter of the cutting piece is worn off by two-thirds, the new cutting piece should be replaced. The cutting piece should be balanced during installation. The soft gasket device between the cutting piece and the receiving plate should be tightly attached. The nut should not be tightened too much to prevent the resin EN12413 cutting discs from being broken. Finally, the protective cover must be installed. 3, bearing grease, generally lubricated with molybdenum disulfide grease, once every six months, once a year for inspection, the cutting machine should be completely dismantled, remove internal dust and oil, clean or replace the bearing, Replace the grease. After disassembly and repair, the cutting machine still needs to check whether the operation is light, whether the bearing runs with no abnormal sound, whether the coil is short-circuited, and finally the no-load operation is about 30 minutes. 4. Before use, measure the insulation resistance with a multimeter, the value is ≥ 2 megohms.

In order to achieve a surface roughness of Ra0.02--0.04 μm for the ground workpiece, the following two methods are used to finely and finely cut the cut piece twice. It is very difficult to grind out Ra0.02--0.2μm by refining with a diamond pen and then using a cutting wheel to fine-tune the wheel after finishing the car. However, if it is refined with a diamond pen and then repaired with a cutting disc for stainless steel after finishing the car, this requirement can be fully achieved. The TL60#ZR1--ZR2 cutting piece can be used for fine repair, and the diameter is about φ100mm. First clamp the cutting piece on a mandrel and then finish the outer circle on a precision lathe to eliminate the yaw. After that, the surface grinding machine is used to finely cut the cutting piece, that is, the cutting wheel is used to finely sand the office wheel. When the cutting piece is trimmed, the head frame is rotated, and the rotation speed is low. The Ministry of Economy and Trade is 80--100r/min, the feeding time is small, the reciprocating economic and trade department is 0.002mm, and the reciprocating speed of the table is less than 0.3m/ Min, it needs to be reciprocated several times. The trimming cutting piece and the trimmed aluminum abrasive cutting disc rotate in the same direction, that is, the line speeds of the contact points of the two are opposite. The coolant should be sufficient to flush the floating sand to prevent the surface of the workpiece from floating on the sand during the grinding process. After the cutting piece is finely and finely trimmed, more contour micro-blades can be trimmed on the abrasive grains of the cutting piece. After the cutting piece is finished, the sand particles on the surface of the trimmed cutting piece are removed by a brush. The coolant should be rigorously filtered before grinding. When grinding, the coolant should be sufficient to prevent burns on the surface of the workpiece. Adjust the gap between the main shaft of the cutting blade and the bearing bush Coloring and bearing bushing on the spindle diameter of the cutting piece, scraping the bearing surface of the bearing pad with a scraper, the contact spot should reach the point of 12--14 points (25×25) mm, and then the installation adjustment will be carried out to cut the spindle of the cutting piece. The clearance of the bearing bush is adjusted to 0.0025--0.005mm. In this way, the drawback of the occurrence of ridges in the workpiece during grinding can be overcome. Balance cutting blade spindle motor and cutting piece Since the vibration of the spindle motor of the low price disc for metal has a great influence on the surface roughness of the workpiece, the spindle motor of the cutting piece needs to be balanced, and the cutting piece should be balanced twice; after the cutting piece is trimmed with a diamond pen, a rough balance is performed, and then the stone is used or After the roughing, the cutting piece is finely trimmed to make a fine balance.
