Instructions for Using Non woven Grinding Products
The significance of common specification representations
Sandpaper and cloth are divided into many varieties and specifications according to the type, particle size, and tissue density (hardness) of the abrasive.
Abrasive: Generally, corundum and silicon carbide are used. Corundum is commonly used for grinding metals, while silicon carbide is used for grinding hard and brittle materials or wood.
Particle size: The coarser the particle size, the higher the grinding efficiency, the rougher the surface texture, and the lower the smoothness. The corresponding mesh fiber structure is more fluffy.
The influence of organizational density on the surface quality of processed workpieces: higher density results in clearer patterns than lower density, and is less prone to pattern tilting or interruption.
Several parameters for using non-woven grinding wheels
The influence of the rotational speed of the grinding wheel on the processing results of the workpiece and the service life of the grinding tool: When the workpiece material is hard and the surface treatment effect requires high, a high rotational speed is needed, but the service life of the grinding tool will be correspondingly shortened; The workpiece material is relatively soft and low-speed is selected, resulting in relatively rough surface treatment results.
The influence of feed rate on local patterns of workpieces: the faster the feed rate, the shorter the time for local grinding, and the fewer the number of pattern segments; The slower the feed rate, the longer it allows for processing of local patterns.
The pressure when grinding the workpiece with a grinding wheel: When the pressure is high, it is easy to burn the workpiece, and the grinding wheel will change shape; When the pressure is low, the texture of the workpiece is not clear enough, and the efficiency is not high enough. Usually, the pressure on the wing shaped grinding wheel is relatively lower, while the pressure on the winding wheel is higher.
⑶ Environment of use
Non woven abrasive sheets can be used in environments with water, oil, or other corrosive agents, without worrying about issues such as rusting of steel wire balls and sanding of ordinary sandpaper. They can be used in conjunction with pallets or directly by hand.
When there are high requirements for the surface, grinding wheels are often used in conjunction with lubricants, which can effectively dissipate heat, improve surface color, and reduce dust.
Non woven abrasive products have the advantages of high efficiency, convenience, speed, safety, and environmental protection compared to traditional abrasive products. In the past, their prices were relatively high for a considerable period of time, and only foreign companies were able to produce them. Although the domestic market is still dominated by foreign brands, the production of sandpaper and sandpaper fabrics in China is developing rapidly, with many of these enterprises located in Guangdong and Jiangsu and Zhejiang provinces. With the gradual localization and rationalization of prices for sandpaper and cloth, it is believed that they will become more popular in the next 3-5 years.
