摘　　要： 通过实验研究了环形电镀立方氮化硼线锯在轮胎断面切割中的性能。线锯的基材为直径2mm的环形钢丝绳,立方氮化硼的粒径为120~140μm。切割参数为:切割线速度为20 m·s^(-1),进给速度为20mm·min^(-1),分别对12.00R20全钢子午胎和195/65R15半钢子午胎进行了断面切割实验。实验结果表明:切割过程中不会对轮胎断面结构造成破坏,切割断面能反映轮胎原始结构。切割断面平整,无需打磨就能观察出橡胶层的分布及钢帘线、帘布线的分布。 The performance of endless electroplating CBN wire saw in the tire section cutting processing was studied in this paper.Endless steel wire ropeΦ2mm diameter was used as substrate.The grain size of CBN was 120—140μm.The cutting speed of the saw was 20m·s^(-1),and the feeding speed was 20mm·min^(-1).The all-steel radial tire 12.00R20 and half-steel radial tire 195/65R15 were cutted in the experimental research separately.The results showed that the sectional structure of tire was not damaged in the cutting process,and the cutting section could reflect the original structure of tire.The cutting section was smooth,and the distribution of rubber layer,steel cord and cord line could be observed clearly without polishing.
