The function effect of waterproof abrasive sandpaper is grinding: Make use of different size and different sand grains in sandpaper to polish the products that need polishing. It makes the products more delicate and smooth. For the grinding function of waterproof abrasive paper, China's sedimentation history is not particularly long, but the development is very strong.
With the invention of the first boring machine for steam engine cylinder, gasoline engine, diesel engine, high-speed gear and bearing appeared one after another. After World War II, steam engine, missile and satellite developed one after another, and the manufacturing precision of parts increased rapidly. The development of metal materials is also closely related to the development of products. Initially, the materials used are mainly low carbon steel and cast iron. However, modern steam turbines must have heat-resistant, wear-resistant, corrosion-resistant and alloy steel composite materials. In the development of space shuttles and satellites, titanium and titanium alloys, other high strength steel and other materials have appeared. The ultimate tensile strength has almost increased by more than ten times.
So abrasive paper sheet is suitable for grinding of various parts of new materials. The performance of grinding machines and wheels has also been further developed. On the basis of the basic type, there are the precision and high precision, semi-automatic, oblique grinding wheel, numerical control, wide grinding wheel, multi-sheet grinding wheel, high-speed, multi-grinding wheel frame, strong grinding and so on.
With the continuous development of modern mechanical processing and the emergence of various new materials, the requirement for surface roughness of water sandpaper processing accuracy is getting higher and higher, and the corresponding grinding loss is constantly appearing to meet the continuous development of modern industry. Over the years, waterproof sandpaper grinding technology is developing in this direction. With the development and promotion of new, super-hard abrasive tools, ultra-precision grinding, efficient grinding technology and development, it is applied in high precision, high rigidity grinding machine and grinding process.
