摘要
文中制做了Φ180、Φ230、Φ350mm的Cu-Ni-Fe基刀头型激光焊通用锯片和Φ180、Φ250、Φ350mm的Cu基热压陶瓷片。通过切割花岗石、水泥和瓷砖,考察了锯片中金刚石浓度对锯片的锋利度和切割寿命的影响。指出:在锯片能正常运转的情况下,金刚石浓度越高,锯片寿命越长;而锯片的最大切割速度则随着金刚石浓度的增加而呈抛物线规则变化,先增后减,有一最大值,并且对应这个最大切割速度的金刚石浓度随锯片直径、被加工材料的不同而不同。文中结论对于配方设计具有指导意义。
Abstract：Cu-Ni-Fe-based laser welding general saw blades of ФP180,ФP230, ФP350mm in diameter and Cu-based hot pressing ceramic blades of Ф180.Ф250,Ф350mm in diameter were made. The effects of diamond concentration on sharpness and durability of diamond saw blades were studied by cutting granite, cement and ceramic tiles. The results indicate that the higher the concentration of diamond, the longer life of saw blade under normal circumstances. The maximum cutting speed of saw blade varies with the concentration of diamond in parabola rule, increasing at first and then decreasing, with a peak value which corresponds to the concentration of diamond varying with different diameters of saw blade and processed materials. The conclusion provides a reference to composition design of the saw blade.
