How to customize grinding wheels? If you already have your own brand, or want to have a different product experience, then you can customize your own products. We can customize the appearance of the product: outer packaging, inner packaging, trademark layout and product color. Of course, we can also customize the performance, such as the use of different materials, we can customize different grades of grinding wheel.
Resin grinding wheel is a grinding wheel made of resin with high strength. It is used in cutting discs, double end faces, heavy-duty grinding wheels, polishing wheels and so on. It has certain elasticity, low heat resistance, good self-sharpening, easy production, and short process cycle. It is widely used for rough grinding, barren grinding, cutting and free grinding, such as grinding steel ingots, casting burrs, etc.
Resin grinding wheels are grinding wheels made of resin, such as phenolic, epoxy, polyurethane, polyvinyl alcohol, etc.. Resin grinding wheels have high strength and can add reinforcing fiber mesh and steel bars, such as cutting discs, grinding discs, and most of us. The resin grinding wheel is not waterproof and cannot be ground with grinding fluid. Of course, there are also some resin grinding wheels that need to be ground with grinding fluid, such as epoxy. The resin grinding wheel has good grinding smoothness and the workdisc is not easy to burn. The resin grinding wheel is used in cutting Discs, double-end faces, heavy-duty grinding wheels, polishing wheels, etc. The strength of resin bond grinding wheels is lower than that of metal bond and ceramic bond.
Resin bond is an organic bond. The grinding wheel manufactured by this bond has high strength, certain elasticity, low heat resistance, good self-sharpening, simple production and short process cycle. It can manufacture grinding wheels with working speed higher than 50 m/s and very thin grinding wheels. Its application range is second only to the ceramic bond, and it is widely used in rough grinding, barren grinding, cutting and free grinding, such as grinding steel ingots and burring castings. It can manufacture high-speed, high-finish grinding wheels, heavy-duty, cut-off and various special requirements.
At the same time, resin-bonded grinding wheels are a tool that is in greater demand. It is a tool made by gluing diamond or cubic boron nitride (CBN) abrasives and inorganic fillers using benzoic acid and polyamide or other resins as binders. This tool is being effectively used in various grinding operations, such as surface grinding, centerless grinding, slotting, and internal grinding. It is an ideal grinding tool for super heat resistant stainless steel, cermet, ceramic products, glass products, limonite, high speed steel, alloy tools and many other new superhard materials.
There are many kinds of special resin bonded diamond grinding wheels for rapid cold cutting. These grinding wheels are particularly suitable for grinding carbide tools (such as saws, cutting machines, drilling tools, end mills, etc.). In addition, these tools can also be used for precision grinding of cemented carbide molds, rollers and carbide wear parts. Resin bonded grinding wheels are the first choice for precision machining of ceramic products and for grinding tungsten carbide and thermal spray coatings on ceramic products. Resin bonded grinding wheels can also be used in combination with CBN to grind high-speed steel, tool and die steel, and super heat-resistant alloys above FtRC50.
In the production process, emery wheels are used to polish the belt. Generally, the grinding wheel should be removed and cleaned after 5-7 days of operation. (There are polished rubber crumbs on it, which adhere tightly to the surface of the emery after high temperature friction, and it is difficult to clean) Now we soak in acetone for 2 hours and then clean it with imported detergent. The effect is very good, but it is not environmentally friendly and energy-saving. Cleaning requirements: 1. To be environmentally friendly, free of ketones and not halogenated hydrocarbons. 2. Don’t damage the diamond wheel.
The grinding wheel must be carefully inspected and identified before installation. The steps of inspection and identification are: 1. Check whether the grade of the grinding wheel is correct and whether it meets the performance, shape and size of all selected grinding wheels. 2. Check and identify the appearance and structure of the grinding wheel. Use your eyes to observe whether the appearance of the grinding wheel is damaged (or cracked). Grinding wheels with appearance damage (or cracks) cannot be used. In addition, both ends of the grinding wheel are required to be flat without any obvious skew. 3. Check and identify the internal cracks of the grinding wheel. Hold the grinding wheel in your hand and tap the grinding wheel with a wooden hammer to listen to the sound. The grinding wheel without cracks emits a crisp sound, and the grinding wheel with cracks has a hoarse sound, which cannot be used.
Color of resin grinding wheel.There are so many colors of cutting discs, what are the specialties? The color of the abrasive itself will affect the color of the cutting discs. For example, the abrasive brown corundum is the black cutting disc, and the abrasive white corundum is the green cutting disc… You must not think of these colors. Let’s explore it with Damon Wheels.
One, increase the beauty of the cutting disc.
In order to improve the aesthetics of the dicing disc, the general manufacturer will add colorants in the production. One is to attract consumers’ desire to buy, and the other is that if the color of the cut disc is too light, colorants can be used to increase the appearance color.
The colorant itself will not affect the performance of the cutting disc itself. There are several types of colorants commonly used by cutting disc manufacturers: red iron oxide, chromium oxide green, iron oxide black, carbon black and carbon dioxide. These materials not only improve the appearance, but also protect the cutting discs and improve the grinding performance, which is profitable and harmless.
2. Adding colorants to increase the performance of the cutting disc
Adding coloring agents to the cutting discs, such as the heating of the cutting discs, the grinding performance, and the light appearance of the color can be effectively solved. Different colorants have different properties such as high temperature resistance, light resistance and tinting strength. It can be seen that many cutting disc colors on the market are divided into three categories: black, green and red. Not only the color of the abrasive, but also the colorant has great uses.
In the production process of the cutting disc, due to the difference in heat resistance, the color changes under the influence of temperature. However, some colorants have good adsorption capacity, no matter how high the temperature is, their color will not be affected.
Three, bright colors help to distinguish
Because different companies of cutting objects also choose different colors of cutting discs. For example, for stainless steel special green cutting discs, ordinary steel can be black or red. Different colors not only help to distinguish the purpose, but also the different colors of the cutting disc can increase the work efficiency and reduce the burden on the operators.
Four, market selection, improve efficiency
The cutting discs on the market are available in yellow, pink, green, black and other colors. Black and green are mainly used in the Asian market, and black cutting discs are very popular in China, South Korea and other countries. For example, yellow cutting discs are used more in Africa and other regions. Yellow cutting discs are mainly made of yellow sand, which is low in price. India’s industrial development is developed, but it prefers to use cheap cutting discs.
The above is the understanding of the color of the cutting disc brought by the Damon grinding wheel manufacturer. It can be known that the color has a great relationship with the performance of the cutting chip. The colorant is only an auxiliary pigment and will not affect the cutting chip itself.
Where the cutting disc is used?
First, choose according to the different occasions where the cutting disc is used. The cutting disc can be divided into cutting type and polishing type from the way of use. Most of the cutting machines are fixed and mobile, and the power of the machine is divided into high power (>5.5KW) and low power (<3KW). The cutting speed can also be high-speed cutting (>80m/s) and ordinary cutting. In addition, there are many kinds of cutting materials when cutting, such as stainless steel, titanium alloy, ordinary steel, viscous metal, high carbon steel, non-metal and so on. Different use occasions have different performance requirements for the cutting disc, so it is very important to choose a reasonable cutting disc. We have to choose the cutting disc according to the occasions we use, which can increase the safety factor, improve work efficiency, and reduce our use cost.
The choice when using the cutting disc of ordinary cutting machine.
The ordinary cutting machine usually refers to a cutting machine with a fixed cutting table, a power <3KW, and a rotation speed of 2900 rpm. Ordinary cutting machines usually cut workdiscs with a diameter less than 50mm. However, due to the low cutting power in order to reduce the radial friction resistance, we usually choose a cutting disc with a thickness of 3.2mm. In this way, the cutting disc is thinner and has a certain degree of elasticity, and it will feel sharper when cutting. In order to reduce the lateral frictional resistance, the products of Changzhou Dome Abrasives Manufacture Co., Ltd. change the surface contact to point contact, and the formulation system adds a lubricant, which can greatly reduce the frictional heat generated during cutting and improve the durability and sharpness of the cutting disc.
High-power cutting machine cutting disc selection.
High-power cutting machines usually use cutting table power greater than 5.5KW, rotating speed of 2800 rpm, and cutting workdiscs with large diameters. Because the torque is relatively large during cutting, the damage to the cutting disc is also relatively large, so the cutting disc is required to have a certain degree of rigidity, we usually choose the thickness 3.8mm cutting disc. At the same time, due to the large cutting diameter, the resistance of the cutting disc will also increase, and the temperature of the cutting surface will be very high, so it is very important to reduce the cutting temperature. If possible, add water to cool when cutting. Experiments have proved that if water cooling is added during cutting, the durability of the cutting disc can be increased by 1.5-2 times. However, in some occasions, there is no condition to add water for cooling, so when Jixiang Abrasives produces high-power cutting discs, powdered coolant is added according to the formula to help reduce the temperature generated during cutting, and to improve the service life of the cutting discs
With the development of the machinery industry in the future, more and more cutting disc industries have begun to approach this market, and many companies have begun to update product technology, hoping to develop more good products.
So which specification of the grinding wheel is good? How can the grinding wheel work safely and efficiently?
1. Good uniform appearance and no cracks are the basic appearance of high-quality grinding wheel specifications;
2. Sophisticated packaging and printed anti-counterfeiting barcodes are the difference between genuine factory products and counterfeit goods;
3. The lower the static imbalance value of any grinding wheel, the better, of course, the more difficult it is to produce;
4. The general rule of cutting and grinding is that the amount of iron removal is small, the grinding wheel is too hard for low abrasion, and the material used is too poor for the less iron removal and large abrasion. The high-quality intrinsic quality is the least possible abrasion and the maximum amount of iron removal. At the same time feel good;
5. For carbon steel, alloy steel, cast steel, stainless steel, copper and aluminum, and glass stone, because their organization density and heating conditions are different, it is decided to choose a different grinding wheel; for glass stone, the market There are special glass and stone cutting and grinding tools; copper, aluminum and stainless steel solid materials should be cut or polished with lower thickness or based on zirconium corundum; hardness is required for cutting carbon steel and stainless steel profiles (not solid) A higher grinding wheel will greatly increase the life; but for solid round steel and forgings, the hardness of the grinding wheel should not be too high, otherwise it will not cut!
6. The choice of the grinding wheel is the material to be ground. The ideal grinding wheel should have good sharpness and hardness. When the abrasive particles are passivated, will they automatically fall off from the bonding agent and make the grinding wheel Good sharpness at all times is an important criterion for safe and efficient operation of grinding wheels.
