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 abrasive during use, when the abrasive blunt HPM31 circle. rods, partially due to its fragmentation or abrasive bond breakage, abrasive grit from the partial or complete loss of steel HPM31, while constantly working surface abrasives emergence of new cutting edge, or continue to expose new sharp grinding tablets, so abrasive within a certain time to keep cutting. abrasive such self-sharpening, is abrasive tool compared with the general prominent feature. Abrasives source of their raw materials, natural and artificial abrasive abrasive categories. Commonly used in machinery industry is only natural abrasive stone. Artificial abrasive characteristics according to the basic shape and structure of the distinction HPM31, there grinding, grinding, Whetstone HPM31 material, sand tile (above collectively bonded abrasives) and coated abrasives five. Moreover, the habits of the abrasive abrasive as a class. abrasive used by the abrasive can be divided into ordinary abrasive abrasive and superabrasive abrasive former general with corundum and silicon carbide and other abrasives, which are made of diamond and cubic boron nitride and other superhard abrasive. Try to improve the finish cold punch and die machining surface to improve the life of the mold. Suitable lubricants added periodically grinding the cutting edge. Note that when you select the appropriate grinding wheel, grinding into the amount and use enough coolant to avoid overheating and cracking grinding. WEDM wire walking should be used, de-stress after tempering process, grinding to remove WEDM metamorphic layers. For dimensionally stable line required precision molds, heat should provide relevant data.
