摘要
高速磨削因其能成功越过磨削热沟的影响,获得较高的磨削效率而得到广泛应用。对转向架构架采用柔性砂带打磨和无齿盘打磨后的焊接接头进行分析测试,结果表明,无齿盘精磨后表面粗糙度明显降低,表面平整,且其近打磨面的微观组织和硬度并未受到打磨的影响,未出现淬硬组织或回火组织,不存在加工硬化现象。
High-speed grinding is used in many fields because it can solve the problems caused by the hot Groove. The welded joints of the bogie are tested after grinding by flexible abrasive belt and gearless disc. The results show that grinding decreases the roughness and increases the flatness of the surface. Quenched structure or tempering structure does not appear,and there is no work hardening.
