Features and applications of sanding belts

In conventional coated abrasive grinding, the abrasive particles are uniformly distributed on the surface of the substrate in a single layer. Uniform particle size is an important factor for efficient and cold grinding of coated abrasives. The typical difference between sanding belt and grinding wheels is that the former operates by improving grinding stress rather than by increasing the belt speed. The linear speed of the abrasive belt is usually between 15m/s-35m/s. At present, coated abrasives are developing in the direction of special purpose, high precision and high efficiency, and have the characteristics of high-speed, strong and heavy-duty grinding. To date, coated abrasives such as sanding disc ,belt and velcro sanding paper has been used in the automotive industry, shipbuilding industry and tool manufacturing.

 

There are advantages of sanding belt grinding: First of all, it can solve large area grinding and complex surface grinding that other abrasive products cannot solve. In addition to the materials that can be processed with grinding wheels, abrasive belt grinding can also process non-ferrous metals such as copper and aluminum, as well as non-metallic soft materials such as wood, leather, and plastic. The "cold" grinding effect during processing of heat-resistant and different abrasive materials makes belt grinding even more unique. Secondly, the sanding belt’s efficiency is high, the heat storage is small, and the workpiece is not easy to burn. The high-quality abrasive belt is reflected in the small surface roughness and no small flaws on the surface. Besides, belt grinding equipment is simple and safe to operate with low noise and dust. Due to the light weight of the belt, it is easier to control the balance than the wheel. In addition, the flexible grinding effect of the abrasive belt can greatly reduce vibration and shock. What’s more, belt grinding has low power consumption, energy saving and environmental protection. The higher the belt grinding force, the higher the power availability and grinding efficiency of the machine.

 

Shanghai Binic Abrasives Co., Ltd., headquartered in Vanke Hongqiaoyun, Minhang District, Shanghai, is an industrial and trade enterprise specializing in the production and sales of sanding disc and polishing sanding paper; it has been exported to more than 20 developed and developing countries abroad. The company always adheres to the business tenet of "quality first, customer first, cooperation and win-win", and wholeheartedly welcomes overseas customers to come to negotiate business

How To Use A Ceramic Velcro Sanding Disc

  Ceramic Velcro sanding discs  are a type of  abrasive tool  that are designed for use with angle grinders or orbital sanders. They are versatile, durable, and suitable for a wide range of sanding and  grinding  tasks. To use a ceramic Velcro sanding disc, follow these steps: 1.  Choose the appropriate   c eramic v elcro s anding disc: Make sure to select the correct ceramic Velcro sanding disc for the job. Consider the material you will be sanding , the desired finish, and the disc’s grit. 2.  Attach the disc: Attach the ceramic Velcro sanding disc to your angle grinder or orbital sander. Velcro sanding discs are designed to be easy to attach and remove, and can be secured in place using a Velcro backing. 3.  Adjust the speed: Make sure the speed of your angle grinder or orbital sander is set to the recommended speed for the ceramic Velcro sanding disc you are using. Too high a speed can cause the disc to wear out quickly, while too lo...

What is the Difference between Asphalt and Concrete Blades?

图片
   When it comes to construction and renovation projects involving roads, driveways, and other paved surfaces, the choice between asphalt and concrete is crucial. Equally significant is   selecting the appropriate blade for cutting and shaping  these materials. In this article, we will delve into the key differences between asphalt and concrete blades, considering their bond, design, price, and various applications.   Bond of the Blade: The bond of a blade refers to its ability to hold the diamond segments together. In the case of  asphalt  diamond  blades , a softer bond is used. Asphalt is a relatively softer material compared to concrete, and a softer bond ensures that the blade cuts through the material more effectively. This bond allows the diamond grits to wear out more rapidly, enabling the blade to maintain its cutting efficiency throughout the project. On the other hand, concrete diamond blades require a harder bond to withstand the abras...

Best Way to Sand Veneer and Lacquer

图片
   Veneer and lacquer are two popular finishes used in woodworking projects. While both provide a beautiful and durable surface, they require different approaches when it comes to sanding. In this guide, we will explore the differences between veneer and lacquer, and provide step-by-step instructions on how to properly sand both types of surfaces. VENEER VS. LACQUER: WHAT SETS THEM APART? Veneer and lacquer are two distinct types of finishes commonly used in woodworking. Understanding their differences is crucial to ensure  proper sanding techniques . Veneer  is a thin slice of real wood that is typically applied to a less expensive wood or composite substrate. It allows the appearance of expensive wood species without the cost. Veneered surfaces are often used in furniture, cabinetry, and decorative applications. Since veneer is made of natural wood, it can be sanded and refinished multiple times. However, sanding veneer requires delicate handling to prevent damage ...
