When the abrasive discs are finished and passed the quality inspection, they can be packaged and shipped. The packaging of abrasive discs includes inner packaging and outer packaging. The inner packaging includes cartons, iron boxes, plastic barrels, etc. Its forms and materials are very diverse, and can be freely customized according to customer needs, even the size and appearance can be freely customized. The outer packaging is generally made of kraft paper and color boxes, which can be customized according to the size of the actual product.

There are many kinds of packages for resin bonded grinding wheels. Generally, we use plastic film to plastic seal the abrasive discs after they are completely cooled. Because the size and thickness of the abrasive discs are different, we believe that the number of plastic discs is different when plastic sealing. For example, for the grinding wheel with a thickness of 1.0mm, our factory usually adopts the method of 25 pieces of plastic packaging or 50 pieces of plastic packaging. For some cutting pieces with a thickness of 3.0mm, we usually laminated them into 10 pieces or 5 pieces. Like angle grinding discs, if the thickness is more than 6.0MM, we usually use 5 pieces for plastic packaging. Of course, this is based on the needs of customers. Some ultra-thin film customers need 20 pieces of plastic packaging, and some need 15 pieces of plastic packaging. We will try to meet customers’ needs if the machine allows. The molding here refers to the complete molding of the grinding wheel. Of course, there is no such large molding machine in China for 14 inch and 16 inch grinding wheel, so these two models usually adopt the semi molding form. After plastic sealing, we will put the grinding wheel pieces into the proper size inner boxes. These inner boxes are white kraft paper boxes, and there are two kinds of kraft paper boxes. Some models have different packaging. For example, the 4-inch cutting pieces have plastic barrels of different colors, and some 4.5-inch and 5-inch cutting pieces have iron boxes for supermarkets. Of course, some customers have special requirements, such as iron bucket, white fresh-keeping bucket, or display box. This is also based on the actual situation.
What’s resin bond grinding wheel?
Resin grinding wheel is made of resin, such as phenolic, epoxy, polyurethane, polyvinyl alcohol, etc; Resin bonded grinding wheels have high strength and can be added with reinforced fiber mesh and steel bars, such as cutting discs and grinding discs. Most of our resin bonded grinding wheels are not waterproof and cannot be grinded with grinding fluid. Of course, some resin bonded grinding wheels that need to be grinded with grinding fluid, such as epoxy bonded grinding wheels, have good grinding finish and are not easy to burn. Resin bonded grinding wheels are used for cutting discs, double end faces, heavy load grinding wheels, polishing wheels, etc, The strength of resin bonded wheel is lower than that of metal bonded wheel and ceramic bonded wheel.
Resin bond is an organic bond. The abrasive discs manufactured by this bond has high strength, certain elasticity, low heat resistance, good self sharpening, simple production and short process cycle. It can be used to manufacture grinding wheel with working speed higher than 50m/s and very thin grinding wheel. Its application scope is second only to ceramic bond, and it is widely used for rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots, casting burring, etc. It can be used to manufacture high speed, high finish abrasive discs, heavy load, cutting off and various grinding wheels with special requirements.
At the same time, resin bonded grinding wheel is a tool in great demand. It is a tool made by bonding diamond or cubic boron nitride (CBN) abrasives with inorganic fillers using benzoic acid, polyamide or other resins as adhesives. This tool is being effectively used in various grinding operations, such as surface grinding, cylindrical centerless grinding, grooving and internal grinding. It is an ideal grinding tool for super heat-resistant stainless steel, metal ceramics, ceramic products, glass products, limonite, high-speed steel, alloy tools and many other new superhard materials< BR>There are many kinds of resin bonded diamond wheels specially made for rapid cold cutting. These grinding wheels are especially suitable for grinding carbide tools (such as saws, cutting machines, drilling tools, end milling cutters, etc.). In addition, these tools can also be used for precision grinding of carbide dies, rollers and carbonized wear parts. Resin bonded grinding wheel is the first choice for precision machining of ceramic products, grinding tungsten carbide and thermal spraying coating of ceramic products. Resin bonded grinding wheel can also be used together with CBN for grinding high speed steel, tool and die steel and super heat-resistant alloy above FtRC50.
Cleaning method
During the production process, emery grinding wheel shall be used to grind the belt. Generally, the grinding wheel should be removed and cleaned after 5-7 days of operation. (There are rubber scraps polished on it, which are tightly attached to the emery surface after high temperature friction and are difficult to clean.) Now we soak it 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. Environmental protection, no ketone, no halohydrocarbon. 2. Do not damage diamond grinding wheel.
Installation requirements
The grinding wheel blades must be carefully inspected and identified before installation. The steps of inspection and identification are as follows: 1. Check whether the brand of the grinding wheel is correct and whether it conforms to the performance, shape and size of all selected grinding wheels. 2. Inspect and identify the appearance and structure of the grinding wheel. Use eyes to observe whether the appearance of the grinding wheel is damaged (or cracked). The grinding wheel with appearance damage (or cracks) cannot be used. In addition, it is required that the two ends of the grinding wheel should be flat and free from obvious deflection. 3. Check and identify the internal cracks of the grinding wheel blade. Hold the grinding wheel by hand and tap the grinding wheel with a wooden hammer to listen to its sound. The grinding wheel without cracks makes a crisp sound, while the cracked grinding wheel is hoarse, which cannot be used.
Resin bonded grinding wheel is generally divided into ordinary resin bonded grinding wheel and superhard resin bonded grinding wheel according to the abrasive. Ordinary resin bonded grinding wheel is mainly composed of white corundum, brown corundum, silicon carbide and other ordinary abrasives, while super hard resin bonded grinding wheel is mainly composed of diamond or CBN.
The common resin abrasive wheels are commonly used in the market, including common resin cutting discs and common resin grinding discs.
1. During the handling and storage of grinding wheel blades, care should be taken not to collide. Resin bonded grinding wheel blades and ceramic bonded grinding wheel blades are prone to notch and fracture after collision.
2. Do not contact with corrosive gases and liquids, especially resin bonded diamond abrasive discs. Contact with corrosive chemicals will change the performance of the resin.
3. Due to the influence of resin aging, the storage life of the grinding wheel should not exceed one year, otherwise, its normal use will be affected. If it must be used, relevant safety inspection must be carried out again.
4. When the grinding wheel is not in use, the coolant shall be washed away immediately to keep the surface of the grinding wheel clean and prevent the oil coolant from penetrating into the grinding wheel, which may cause the imbalance of the grinding wheel when it is used again.
5. The grinding wheel shall be stored at room temperature as far as possible to avoid contact with high or low temperature.
What are the different characteristics between resin grinding wheel and ceramic grinding wheel?
1. In terms of color, ceramic grinding wheels are generally blue, white, red, green, black, etc. according to different materials, and the resin is generally dark brown.
2. In terms of smell, ceramic grinding wheel is generally odorless, and resin grinding wheel has tartaric acid odor of resin.
3. In terms of sound, the ceramic grinding wheel generally makes a crisp sound when knocking, while the resin grinding wheel makes a mute and deep sound.
4. Resin grinding wheel and ceramic grinding wheel are different from each other. As far as the nature of the bond is concerned, ceramic bond is inorganic bond, while resin bond is organic bond.
As a result, the properties and uses of the two grinding wheels are different:
1) Ceramic grinding wheel: because its bond is ceramic, its chemical composition is stable, heat resistant, water resistant, strong, but brittle. For example, for cylindrical grinding machines and surface grinding machines, because the grinding wheel will generate a lot of heat when it is working, it is better to use a ceramic bond to wash and cool it.
2) Resin grinding wheel: resin is an organic bond, so it has high elasticity and strength. But the firmness, heat resistance and corrosion resistance are poor. When the grinding wheel is used for end grinding, resin type grinding wheel is selected; Thin resin bonded grinding wheel can be selected for material cutting; Resin bonded grinding wheel shall be selected when the grinding wheel speed is high.
The raw materials of Dome grinding wheel are directly supplied by international and domestic high-quality manufacturers to ensure the stability of the materials. The production and heat treatment are all completed by our factory. The stability of the size, characteristics and life of the products can be ensured through the whole process control.
First of all, let’s take a look at the polishing disc. It is made by planting fine abrasive particles (aluminum oxide or silicon carbide) on the high-strength polyester film with the help of high-voltage electrostatic field force, so that all the sharp knives of the abrasive particles face outward and cut sharp, which can provide higher grinding efficiency and bright and delicate polishing effect, and then it is processed by backing and cutting. The abrasive grains of the grinding disc are arranged in a directional manner, and the product surface is sharp, ensuring good grinding efficiency of the abrasive belt. Its product surface is evenly distributed with abrasive particles, combined with special adhesives to prevent deep and irregular lines, and its good chip removal capacity is not easy to cause blockage. In general, the function of this consumable is to grind the workpiece.
Let’s take a look at the cutting disc. The cutting disc is a thin piece made of abrasives and binder resin, which is used to cut ordinary steel, stainless steel metal and non-metallic materials. It mainly uses glass fiber and resin as reinforced bonding materials, and has the characteristics of high tensile, impact and bending strength. Therefore, it is widely used in the production and blanking of ordinary steel, stainless steel metal and non-metallic materials. The cutting disc is thinner than the grinding disc. If we do not know these two consumables, we can distinguish them by their thickness.
Let’s look at the grinding wheel. It can also be called grinding wheel. After all, its role is also polishing. Disc sand is a round grinding disc made of sandpaper. It can be divided into two types: velvet and double-sided adhesive tape. It is used to polish hardware accessories, plastics or automobile accessories. It is faster than ordinary sandpaper when used. The grinding wheel is a very common abrasive tool in the grinding process. It is usually made by adding a bond to the abrasive and pressing, drying and baking it. Its characteristic parameters mainly include abrasive, viscosity, shape, hardness, bond, size, etc. According to the abrasive, the grinding wheel can be divided into ordinary abrasive (corundum and silicon carbide, etc.) grinding wheel, natural abrasive super hard abrasive and (diamond and cubic grinding wheel boron nitride, etc.) grinding wheel; According to the shape, the grinding wheel can be divided into flat grinding wheel, cup grinding wheel, cylindrical grinding wheel, bevel grinding wheel, disc grinding wheel, etc; According to the bond, the grinding wheel can be divided into metal grinding wheel, rubber grinding wheel, resin grinding wheel, ceramic grinding wheel, etc.
