如何鉴别**的硬质合金锯片？How to identify high quality carbide saw blades?

　　硬质合金锯片由锯板和硬质合金锯齿两部部组成。硬质合金锯齿目前基本上是进口的。**锯片所用的合金颗粒较厚、较大，因为这样的合金锯齿可经多次刃磨，使用寿命长，硬质合金的焊接质量也十分重要，焊缝要薄并且均匀，这样锯齿上能承受更大的切削力。锯片锯板的质量是十分重要的。因为锯片调整旋转，它既要传递切削力又要保持工作的稳定性。优良的锯片不仅具有静态几何尺寸和精确度，更重要的是它的动态特性。当锯片连续切削时，合金锯齿切削所产生的热会传导给锯板，使锯板的温度升高，**的锯板在这种情况下还能保持表态的精度，而质差的锯片就会发生锯板翘曲，影响锯切精度。锯板的动态稳定性对于几片锯片成组使用的精况尤为重要。当多片锯设备使用一组不稳定的锯片又如何能保证纵向开料的质量。锯板和刀头是**锯片不可分割的组成部分。

The carbide saw blade consists of saw blade and carbide saw blade. Carbide serrated teeth are now largely imported. High quality saw blades used in the alloy grain thicker, larger, because such alloy blade by grinding for many times, service life is long, hard alloy welding quality is also very important, weld thin and uniform, it can bear larger cutting force on the sawtooth. The quality of saw blade is very important. Because the saw blade adjusts the rotation, it needs to transfer the cutting force and maintain the stability of the work. Good saw blade not only has static geometry size and precision, but also its dynamic characteristics. When saw blades for cutting, alloy blade cutting generated by heat conduction to sawing plate, make sawing plate temperature, high-quality sawing plate in this case also can keep the precision of position, and poor quality of the saw blade sawing plate buckling occurs, affect the cutting precision. The dynamic stability of saw blade is especially important for the precision of several saw blades. How to ensure the quality of longitudinal cutting when a set of unstable saw blades is used in multi-blade sawing equipment? Saw blade and tool head are integral parts of high quality saw blade.
