Yong Wei steel mold (Dongguan) Co., Ltd. _ Japan Datong S7_S7 provided by Yong Wei steel mold (Dongguan) Limited. We are a steel mold, Dongguan City, An Yongwei shop (www.dgyongwei.com) located at: Dongguan specializes in: mold steel, DC53, SKD11.SUS440C, SUS420 abrasive grinding abrasives can play a role in the most fundamental factor, abrasive The species is very large, chosen to be consistent with the principles of the material properties of the workpiece to be machined. In the choice of S7, also need to consider when abrasive grinding abrasive materials and abrasive workpiece thermal stability between chemical reactions and abrasives etc. To select the desired particle size and the grinding efficiency considering the roughness of the working surface. When a large surface contact area abrasive and bows, or when it is large grinding depth S7 mold, you should choose the coarse granularity of abrasive. Coarse granularity friction surface is less abrasive and Japan Datong S7, heat is also small. Currently, there is excess capacity in the state of corundum, the next step will be the focus of national policy alumina industry backward production capacity, closure of some high-energy small alumina producers S7 sheet, out of a low-power smelting furnace encourage competitive enterprises bigger and stronger. Coated Abrasives in energy conservation policy, environmental pollution has become the most important of coated abrasives production process. While in the production process of the coated abrasive energy and pollution is not the most serious, but the production process of air pollution particles in the waste water and industrial waste water pollution and damage to the environment.
