为减少核工业热室遥控操作更换卧式铣床用圆锯刀的工作量,以及降低报废刀具的清洁解控成本,自制了激光表面淬火强化圆锯刀,将其与M2普通圆锯刀、TiN涂层圆锯刀、氮化圆锯刀作为研究对象,进行了主轴转速为190 r/min、纵向进给量为160 mm/min切削条件下高速干切削316L不锈钢管材的干切削实验,结果表明:氮化圆锯刀的耐用度最好,TiN涂层圆锯刀次之,而经激光表面淬火强化的圆锯刀的耐用度反而不及普通圆锯刀。结合显微组织及其特性阐述了TiN涂层、氮化圆锯刀的干切削磨损机理;结合表面形貌、显微组织、显微硬度分析了激光表面淬火强化圆锯刀的干切削磨损机理。论述了4种圆锯刀高速干切削316L不锈钢的...

In order to reduce the workload of replacing circular saws for horizontal milling machines by remote operation in the hot chamber of the nuclear industry,and to reduce the cleaning and scrap cost of tools,a laser surface hardening strengthened circular saw is made.Compared with M2 ordinary circular saw blade,TiN coated circular saw blade,nitrided circular saw blade,dry cutting experiments of high speed dry cutting of 316L stainless steel pipes with a spindle speed of 190r/min and a longitudinal feed of 160 mm/min are performed.The results show that:nitrided circular saw blades have the best du...
