卧式机床用金属带锯条:钜齿数的选定
Selection of Teeth:
Metal Band Saw Blades for Cut Off Machine

对于被锯工件的长度,钜刃部齿距过大且锯齿数较少,刚会使切割不稳定,又由于每一锯齿的切割负荷增加,则容易使钜刃崩损;相反,如果钜刃齿距过小,则容易产生钜屑堵塞现象,并可能再使用后不久即出现磨耗与损伤。切割韧性良好且较质软的工件时,应尽量使用粗锯齿的锯条,如果希望得到良好的切割面,则应选择使用细锯齿的锯条,根据被锯工件形状的不同,也有必要选择适当的锯齿数,对于形钢、柱建、管件等切割长度急剧变化的被钜工件,建议采用不同齿距的带锯条。

Nonferrous materials such as brass,bronze and aluminum repquire a large chip areamAlow TPI,or"coarse"pitch,prevents the chips from clagging and bunding together in the gullets,which can diminish sawing and damage the blades.

Coarse pich blades are suitable for tough work material,Better finish can be obtained by finer pitch blades,On thin walled pipe or tubing,tooth type of VL is recommended.The features of VL is re[etition of different tooth pitch and much samaller vibration and remarkable ectension of blade life.
