摘要
(WO2017113040) 一种​圆锯​片​及其​制造​工艺,特别是​一种​金属​冷热​切圆​锯片​及其​制造​工艺。该​圆锯​片​包括​锯片​片​体(1),锯片​片​体(1)的​外​圆周​设置​有​硬化​耐磨​层(3)。制造​工艺​是:锯片​片​体(1)下​料、片​体(1)热处理、片​体(1)校​平、片​体(1)准备、片​体(1)精​校​平、堆焊​或​熔​覆​位置​的​预加工、硬化​耐磨​层(3)的​制作、成品​校​平、侧​隙​磨削、齿形​加工、成品​精​平,使之​达到​工艺​要求​范围,具备​上​锯​使用​条件。该​锯片​片​体(1)的​外​圆周​内设​置​的​硬化​耐磨​层(3),使​锯片​在​工作​时​保持​两个​尖角​在​长时​间内​处于​锋利​状态,减少​锯​切​毛刺、延长​锯​切​时间,在​瞻​齿​钝化​后,仅​需要​修复​齿形,不需要​齿​尖​再​淬火,就能​恢复​使用​效果,尤其是​能够​满足​高强度、厚​壁​难​切​工件​的​加工。
