n.劈痕；截口；切口
Kerf is slick with high precision. 锯口精度高、光滑平整。
Application of kerf and rock bolt in Jinyuan Gold Co., LTD. 切缝加锚杆综合措施在金圆公司的应用。
Adopt special structure saw blade , The kerf is smooth and beautiful. 采用特殊结构锯片，切口光滑美观。
Starting saw with blade against material to be cut or pushed forward into kerf can result in kickback. 锯齿靠着被切割的材料启动或者启动中推入锯口会导致反冲（后坐）。
At higher frequencies, the spacing is small and this in turns limits the kerf width between two adjacent channels. 另外，压电材料的厚度亦正比于波长，故在高频时由于材料太薄而使得切割易造成碎裂。
The y are characterized by narrow kerf, high accuracy and productivity, energy and material saving. 具有切口窄、切割精度好、生产效率高、节能和节材等优点。
