轧花机、剥绒机锯片是棉花加工机械的主要易损件,全国每年大约消耗200至250万片,其中剥绒锯片占70～80%,耗用钢材2000～2500吨。目前我国生产的锯片是用65Mn或55钢进行调质处理的,硬度为HRA60～66。锯片表面进行镀锌或电泳涂漆处理,以防腐蚀。由于锯片系直径为320毫米,厚度为1毫米的薄片,经淬火处理后,变形极大。为了达到不平 Cotton ginning machine, stripping machine saw blade is the main wearing parts of cotton processing machinery, the national consumption of about 200-250 million per year, of which stripping cashmere saw blades accounted for 70 to 80%, consumption of 2000-2500 tons of steel. At present, China’s production of saw blades is tempered with 65Mn or 55 steel, hardness of HRA60 ~ 66. Saw the surface galvanized or electrophoretic paint treatment to prevent corrosion. As saw blade diameter of 320 mm, a thickness of 1 mm sheet, after quenching, deformation greatly. In order to achieve the uneven
