Yong Wei steel mold (Dongguan) Co., SK4 rod, SK4 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 workpiece machining accuracy and finish higher, when the need to use fine-grained grinding with, because the finer SK4, abrasive cutting, the more the residual number, the smaller the traces of the abrasive cutting, the surface roughness is smaller. Reasonable choice of abrasive hardness SK4 rod, is the key to get a good grinding effect. The most basic principle is to ensure that in the process of grinding the mill with the appropriate self-sharpening Shenzhen SK4, abrasive wear in order to avoid too large or burn the workpiece. Select soft abrasive grit generated during off razor, causing unnecessary wear and tear, this will cause unnecessary wear and tear. Meanwhile, Guangdong SK4, abrasive will follow the rapid growth of the world, mainly due to abrasive further expansion in China and other emerging market economies, and the sudden emergence of super-hard materials and products. The coated abrasives because of its growing technological innovation, it has the largest number of products in abrasives categories, but also because of the unique advantages of coated abrasives in the grinding process chain late, greatly promoted the coated Application of abrasive polishing.
