polishing sisal wheel

Polishing sisal wheel, also known as hemp polishing wheel or hemp fiber polishing wheel. As a widely used grinding material in the polishing process, this product is widely used for grinding and polishing of hardware, stainless steel products, aluminum products, electroplating products, wood products, and leather materials. Types of sisal wheels 1. Hemp wheel: The main material is made of hemp cloth, strong toughness cotton thread, and oblique cut cotton cloth, which are sewn by a high beam sewing machine. The hemp cloth is sharp, and the cotton cloth is sticky to wax. Under the dual action, it shows special grinding force. 2. Oil hemp wheel: Made from high-quality domestic hemp as raw material, pressed by a sisal cart, and soaked in special oil treatment before air drying, it is wear-resistant, temperature resistant, and has strong cutting force. 3. Oil hemp cloth wheel: It is made by sewing two layers of cotton cloth with a layer of hemp cloth, and has the ability to cut and polish to a certain extent. It is mainly used on metal products. Production process The production process of sisal wheels has been used by manufacturers for decades to cut hemp cloth into the required size using traditional techniques, and is made by hand or machine layering sewing. There may be slight differences in standards or quality between individuals. The use of hemp wheels Ma Lun needs to be used in combination with polishing wax to better exert its polishing effect and achieve the desired polishing effect. polishing Solid wax is commonly used. Polishing workers need to choose different polishing waxes to match according to the requirements of different workpieces, and different types of polishing waxes will also use different colors for easy differentiation. Polishing workers also need to add polishing wax to the hemp wheel from time to time during the polishing process to avoid insufficient polishing wax affecting the polishing effect. At the same time, this also increases the workload of workers and reduces work efficiency. And the combination of solid polishing wax and sisal wheel due to insufficient adhesion can generate a large amount of dust during the waxing process, which can also pose serious health risks to the respiratory system of workers. In order to better solve the above-mentioned problems, many factories now use polishing liquid wax. The advantage of this technology is that it combines evenly and tightly with the polishing wheel, reduces waste, and can effectively cool the polishing wheel. However, the use of liquid polishing wax requires specialized equipment to spray onto the surface of the polishing wheel during use. It requires the use of a pressure bucket paired with a high-pressure spray gun, which uses timed and quantitative high-pressure spraying, automation, and no manual labor.

Surface polishing treatment of aluminum products

Surface polishing treatment of aluminum products In our daily lives, aluminum products have been increasingly integrated into our lives, ranging from lipstick casings to automotive accessories. These large and small aluminum products need to undergo surface treatment before they can enter normal use. There are various methods of surface treatment for aluminum products, and most companies require a bright effect, so polishing is the best choice. Below, we will briefly introduce the commonly used polishing treatments for aluminum products. The commonly used polishing method for aluminum products - mechanical polishing The principle of mechanical polishing: After adding polishing solid compound to the polishing buff wheel, polish the surface of aluminum parts on a high-speed rotating polishing machine. The high-speed rotating polishing buff wheel generates high temperature due to friction with the workpiece, causing plastic deformation on the metal surface, thereby smoothing out the convex and concave points on the metal surface. At the same time, the extremely thin oxide film on the metal surface generated instantly under atmospheric oxidation is repeatedly ground down, making it increasingly bright. Why do we need polishing? In the processing of aluminum products, anodizing is usually used as the last step to protect the aluminum parts. Because aluminum alloys are generally prone to oxidation, although the oxide layer has a certain passivation effect, long-term exposure can cause the oxide layer to peel off and lose its protective effect. Therefore, anodizing treatment utilizes its easy oxidation characteristics to control the formation of the oxide layer through chemical methods, in order to prevent further oxidation of aluminum and increase its surface mechanical properties. But before anodizing, it is necessary to determine whether the workpiece has defects. If there are scratches, anodizing treatment should still be carried out, and the marks cannot be covered and may even become more prominent. The main function of polishing is to remove surface defects such as burrs, scratches, corrosion spots, sand holes, and pores from the workpiece surface. At the same time, further remove minor unevenness on the surface of the workpiece to give it a higher gloss. Examples of polishing applications for aluminum products Our company uses century old brand technology in surface treatment technologies such as polishing, and we provide customers with various surface treatment solutions and high-performance materials for a long time. If you have any needs, please feel free to contact us. Below is an introduction to our company's polishing solutions for two common aluminum products, aluminum lipstick shells and aluminum pots. The polishing materials required in the polishing process can be directly used from our company's products. Aluminum lipstick shell polishing: The polishing process of the aluminum lipstick shell includes rough polishing and fine polishing. The rough polishing process can be carried out using our specially processed polishing hemp wheels combined with our specially designed cutting force polishing yellow wax, and then polished with a mouth shaped polishing machine. After rough polishing, the stretching lines generated during aluminum processing can be removed, improving surface smoothness and glossiness. The fine polishing process can use efficient black BK chemically treated oblique cutting cloth wheels combined with polished yellow wax for fine polishing and polishing, which can remove the hemp wheel patterns generated during rough polishing, forming a flat and bright surface. Aluminum Pot Polishing: The polishing process of aluminum pots includes rough polishing, intermediate polishing, and fine polishing. Rough polishing: We can use our company's specially treated large wave hemp cotton cloth wheel with yellow polishing wax for rough polishing, which can remove residual marks on the surface of aluminum processing and improve the glossiness and flatness of the surface. Middle polishing: The middle polishing adopts a slanted cutting cotton cloth wheel combined with our company's characteristic sizing cloth and yellow polishing wax for polishing, to remove the hemp wheel pattern generated during rough polishing and further improve the surface glossiness and smoothness. Fine polishing: Fine polishing is carried out using oblique cutting cotton cloth wheels and white polishing wax. After fine polishing, the surface of the aluminum pot becomes very smooth and has a good glossiness. Aluminum parts can obtain a clean surface after polishing, improving the quality of surface decoration; Improve product grade; Obtain good epigenetic conditions.

Discussion on cotton Cloth Wheel Polishing

Among all grinding and polishing methods, cloth wheel polishing is a magical existence. Today we plan to introduce this unusual polishing method and discuss practical operating modes. What is cotton cloth wheel polishing Cloth wheel polishing is a polishing technique that uses a high-speed rotating polishing cloth wheel to remove grinding slurry and generate heat on the surface of the workpiece through friction. The surface hardness of the workpiece will temporarily decrease to a certain extent, and pressure will be applied at this time to significantly reduce the surface roughness of the workpiece. Although very traditional, it is very effective and economical, mainly used for metal materials. If the cloth wheel polishing technology is described in eight words, it would be as follows: "Friction generates heat and plastic deformation" The part of "heat generation through friction" does not need to be explained. What needs to be explained is usually the part of "plastic deformation". Take the clay that everyone played with when they were young as an example. Clay is a material that can easily shape itself by applying pressure to its surface, and this characteristic is called "plasticity". Materials with good plasticity can be easily shaped into various shapes. Due to the fact that the process of making rough surfaces smooth is also a form of changing shape, such characteristics are also utilized in polishing. Why does friction generate heat? Metal materials and thermoplastic materials only have lower hardness and better plasticity at higher temperatures. Therefore, in order to enable the material to smoothly change the surface shape of the workpiece through the application of external forces, friction heat generation is used to temporarily reduce the hardness of the material and improve its plasticity. If everything goes smoothly, you can see the process of easily changing the shape of the metal like clay. On soft metals with lower hardness, they can even be pushed back and forth like clay. About polishing machines What is a "polishing machine"? The so-called polishing machine is basically a motor, and then the polishing wheel is fixed on the motor spindle to rotate. In fact, there is not much difference between a polishing machine and a sanding machine. Friends who already have a sanding machine can directly install a suitable size of polishing wheel. If you want to buy a polishing machine, try choosing the longer the shaft, the better. A polishing machine with a short axis or a general sanding machine may be difficult to use when polishing large workpieces due to the impact on the motor casing. (The operable space is too small) Usually, the polishing machine used in the polishing workshop is floor standing, which drives a shaft as thick as a ball bat through a belt and opens a large hole in the center of the polishing wheel that matches this shaft. In general, a polishing machine is a fixed polishing wheel with a motor axis straight out. In addition, due to the friction of the workpiece against the wheel during polishing, the polishing machine must be firmly fixed on the ground or workbench. What are some things to pay attention to when using a polishing machine? It should be noted that the holes between the sanding machine axis and the grinding wheel, as well as the holes between the polishing machine axis and the polishing wheel, are not limited to a single size. However, in principle, they are all conventional sizes. Therefore, soft polishing wheels can enlarge the holes, and if the holes are too large, a sleeve can be added to the axis. (But a hard grinding wheel certainly cannot make the hole bigger) How to fix the polishing wheel on the polishing machine? There are two common ways to fix the polishing wheel of a polishing machine. One is the conical sleeve with screw teeth, commonly known as the "mouse tail". The advantage is that it can be directly inserted without the size of the pipe hole. The disadvantage is that there may be slipping teeth when polishing with a lot of force. Therefore, it is safer to lock the polishing wheel with a nut, but it is slightly more troublesome to replace the polishing wheel. Due to the large amount of dust generated during polishing, many polishing craftsmen use cardboard to make appropriate baffles. About polishing wheels A polishing wheel is a type of grinding wheel composed of various fabrics or fibers. Unlike various grinding wheels commonly used for grinding and polishing, the polishing wheel itself does not contain any abrasive material, so it does not have any grinding and polishing effect. The most important aspects of a polishing wheel in practical use are its hardness and density. As the polishing wheel becomes stiff due to centrifugal force during rotation, the resistance to friction with external objects is called hardness. A high hardness cloth wheel is equivalent to using force to press sandpaper against the surface of the workpiece for grinding, while a low hardness cloth wheel is equivalent to using slight force to grind. So the density of the stitching thread on the polishing cloth wheel of the same fabric will affect the hardness, and a part of the stitching thread can also be removed to create a softer version of the cloth wheel. For some people who have no concept at all, you can choose cloth wheels with different hardness to form a complete set of "coarse, medium, and fine". From high hardness to low hardness, they are: flat hemp wheel, sewing thread flat cloth wheel, and no sewing thread flat cloth wheel. About polishing wax The abrasive material in polishing wax generates heat due to high-speed friction with the surface of the workpiece. Although the abrasive itself has the ability to cut the workpiece, the grinding effect it can produce is very limited due to the fine scale of the abrasive material in the oil soil. It is generally best to understand it as a tool used to manufacture frictional heat. Although the abrasive in polishing wax has a specific thickness, the effect that a polishing wax can produce can vary over a large range. Therefore, we basically do not indicate the thickness of the polishing wax. In this case, the most accurate way to judge is to actually use it for grinding. Of course, the thicker the polishing wax, the greater the destructive power it can produce. There are generally several methods that are not absolutely correct but can be used as a reference to distinguish thickness, without spending money to buy: 1. The larger the packaging quantity, the thicker the (large strip) oil soil is usually considered, because all grinding and polishing consumables are thicker, and the larger the usage. The higher the unit price (usually smaller bars), the finer the grinding material, as the production cost of the finer grinding material is higher. Basically, it is completely free to match the hardness of the polishing cotton cloth wheel with the thickness of the polishing wax. In addition, the force of the workpiece friction cloth wheel can be changed over a large range (with your hands). Therefore, according to the principle of cloth wheel polishing, which is "friction generates thermoplastic deformation", corresponding adjustments can be made without being too rigid in finding the "correct" combination

Polishing cottoncloth wheel structure

The structure of polishing cloth wheels is mainly divided into the following three types: 1. Sewn thread cloth wheel This type of cloth wheel is generally cut from raw materials such as twill cotton, coarse fabric, non-woven fabric, and fine plain fabric, and is sewn with strong sewing. The sewing thread is generally in the form of concentric spiral and direct radiation, which has relatively strong grinding force. The specifications can be produced according to the size provided by the customer. 2. Wind turbine (air-cooled cloth turbine) This type of cloth wheel generally uses fine count cotton fabric as the raw material, and there are also cotton heavy-duty fabrics or canvas as the raw material, cut using a 45 degree angle cutting method, and the overall shape is circular wrinkles, with a central iron installed in the middle. Due to its 45 degree oblique cutting, the fibers will not fall off, resulting in high cutting efficiency during polishing. This type of cloth wheel has moderate hardness and good flexibility, suitable for polishing flat surfaces or products with high and low drops, irregular wrinkles, and cooling effect during the polishing process. 3. Buckle cloth wheel (non sewn whole cloth wheel) This type of cotton cloth wheel is generally made of fine soft cotton fabric, and the buckle cloth wheel is generally divided into two types: poplin and anti feather cloth. The difference is that the anti feather cloth has higher hardness and density than poplin, greater grinding force, and more wear-resistant. This type of cloth wheel is generally used for the final polishing process - mirror treatment, which has good flexibility and slight grinding force. It is suitable for polishing complex shaped workpieces or for precision polishing of small workpieces. *Precautions for using polishing cotton cloth wheels 1.In order to achieve the best effect of the polishing buff wheel, the required polishing cotton cloth wheel should be configured according to the material and size requirements of the polishing machine. 2.The size of the polishing wheel is determined by the power of the polishing machine motor, and the aperture of the polishing wheel needs to match the motor shaft. 3. The polishing buff wheel should be placed in the center of the shaft and must be tightened with a wrench, otherwise accidents may occur during high-speed rotation. 4.To ensure the polishing effect, the surface linear speed of the polishing wheel should be uniform. Therefore, if too large a polishing wheel is used with a smaller motor, the linear speed will significantly decrease during polishing, and the polishing effect will also be affected.

What are the types of polishing buff wheels

What are the types of polishing buff wheels 1. Brush polishing wheel The brush polishing wheel is made by fixing bristles of different materials and thicknesses onto the wheel core. The brush polishing wheel is mainly used for removing surface rust, removing oxide skin, polishing and other operations. Due to the rigidity, material, and length of brushes, they exhibit different effects on different surfaces and working environments. For example, when polishing metal surfaces, metal bristles can make the surface shiny and not damage the surface, while cloth bristles are suitable for areas with narrow contours, paint surface carving, and fine mold deburring. 2.cotton Cloth wheel polishing buff wheel The cotton cloth wheel polishing wheel is woven from cloth strips of different materials and is commonly used for grinding and polishing soft metals such as copper, aluminum, and zinc. The fine weaving structure of the cotton cloth wheel allows the polishing compound to easily and uniformly adsorb, diffuse, and release, thereby achieving rapid and uniform removal of surface oxide layers, metal rust, and other issues. 3. Velvet polishing wheel The velvet polishing wheel is similar to the cotton cloth wheel, but has a fine and soft surface texture in the selection of fabrics. Compared with cloth wheels, velvet polishing buff wheels are more suitable for cleaning and processing materials that require high gloss surfaces, such as polishing glass, gemstones, and other materials. 4. Sponge polishing wheel Sponge polishing wheel is a design similar to a mop, which is composed of sponges of different sizes and is suitable for surface polishing and processing. The appearance of the sponge polishing wheel is similar to that of a brush polishing wheel, but because the sponge is not easily deformed, it can save more time when used.
