Yong Wei steel mold (Dongguan) Co., Ltd. | HPM31 Rods | HPM31 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 industrial energy conservation long way to go. As a special abrasives industry HPM31 materials, abrasive smelting problems exist in terms of energy saving. Currently corundum situation exists overcapacity HPM31, the next focus will be the elimination of national policy corundum industry backward production capacity, shutting down part of the production of energy-intensive small and medium enterprises corundum, out of a small power smelting furnace, encourage competitive enterprises to do bigger and stronger. Corundum overcapacity caused by price competition is the main reason, some companies get rid of the current popularity of production HPM31 rod, according to the market demand for targeted production of marketable products, abrasives calcined plated iridium, etc., have mass market to meet abrasive production needs, not only improves the efficiency HPM31 sheet, returned high-grade production of abrasive materials provided. Workpiece machining accuracy and finish higher, when the need to use fine-grained abrasive, because the finer the grit, the more the number of residual abrasive cutting, cutting traces of the smaller, the surface roughness is smaller. Reasonable choice of abrasive hardness, is the key to a good grinding effect. The most basic principle is to ensure that in the process of grinding the mill with the appropriate self-sharpening to avoid abrasive wear too much or burn the workpiece. Select soft abrasive grit generated during off razor, causing unnecessary wear and tear, this will cause unnecessary wear and tear.
