Introduction and functions of parts of saw blade

03.热胀槽
可以降低噪音传播强度，起到消音的作用，且能够改善锯片的冷却效果，提高锯片刚性、保持良好的平面度，从而延长锯片的使用寿命。

03.Thermal expansion slot
Reduce intensity of noise transmission to reduce noise, improve cooling effect of saw blade,improve its rigidity and keep good flatness to prolong the service life.

04.铜钉
防止切缝因应力过于集中而 产生开裂;在止裂孔内镶嵌有铜钉作为填充材料，可很好的起到缓冲作用，降低在止裂孔处产生裂纹的概率;同时，利用铜与钢材的不同阻尼系数。

04.Copper nail
Prevent kerf from cracking due to concentrated stress; copper nail embedded in the crack-stopping hole asfilling material has
good buffering, and reduces probability of cracks in crack-stopping hole; meanwhile, use the different damping coefficients of copper and steel.

05.锯片散热孔
散热消音效果好、切割精度高、使用寿命长等优点。

05.Heat dissipation hole of saw blade
Good effect of heat dissipation and silencing, high cutting precision, long service life and so on

06.锯片消音线
解决了 膨胀问题，又减小了噪音，使锯片在工作中更加平稳，提高了切割精度。
06.Silencing string of saw blade
Eliminate expansion and reduce noise; improve stability and cutting precision of saw blade.

07.引力圈
控制锯片发热后的应力，使锯片不偏摆，从而保证更长的使用寿命和更好切削质量。
07.Circle stress
Enhance stiffness of saw blade,and guarantee longer service life and better cutting quality.
