What is the principle of selecting the material of nanometer sand mill:
(1)Note that the material of the nanometer sand mill is generally softer than the material of the workpiece. This can avoid the grinding process, grinding particles are embedded in the workpiece surface and affect the use of. Choosing the material of nano sand mill is much better than that of the workpiece material, which should be determined according to the different requirements of the sand grinding performance and the size of the abrasive particle size.If use nanometer sand mill material is too soft, grinding grain will be most or all embedded in the nanometer sand mill surface, make the abrasive cutting is lost. Secondly, the material is too soft nanometer sand mill wear quickly, easy to lose precision right. Besides, abrasive particles can be easily embedded into the surface of the nano sand mill, but it is not firm, so it can not be used as a fine grinding of sand. < /span>If the material is too hard, abrasive particles can not be embedded in the surface of nano grinding mill. It is not used, and it will accelerate the grinding and refining process of grinding grain, which can reduce the cutting ability and service life of the abrasive. Secondly, the material is too hard even grinding grains embedded is inclusive is small and easy to peel, the same can not be used for block sand fine grinding work. < /span>
When the abrasive particle size is large, the nanometer sand mill should choose the soft material, when the abrasive particle size is smaller, the nanometer grinding mill should choose the hard material. For example, block sand grinding star block with cast iron nanometer sand mill, in the coarse grinding, embedded white corundum research grinding particle size is W3.5, selection of hardness HB 110-140 better, in the fine grinding, embedded self corundum research grinding particle size is W1--W1.5, selection of hardness HB 130-180 is preferred. < /span>
(2)The material of nanometer sand mill should be suitable for the kind of abrasive material. When the selection of white corundum and Boron Carbide Abradant, often using cast iron, mild steel and copper material of nanometer sand mill. When the selection of chromium oxide abrasive, often using glass, asphalt, cast iron and felt material of nanometer sand mill; when the selection of diamond abrasive grinding powder or grinding paste), often using glass and cast iron material of nanometer sand mill.
