孕镶钻头金刚石出刃量,系指钻头在钻进中金刚石出露部分的顶点,与其根部胎体表面的高差。出刃量的大小直接影响着钻头的寿命与钻速。因此,研究金刚石出刃量和有关因素,对合理设计钻头,正确选择钻进参数,都有着重要意义。金刚石出刃量的测试方法一、样品制备对于大直径钻头,可垂直唇面切下一部分扇形胎块,并将两侧断面磨平,制成样品。直径小于47毫米的钻头,可直接进行测量。二、测试仪器 JGX—1型小型工具显微镜。三、测试方法 1.将仪器按要求安装调试好。 2.将扇形胎块试样横放在测量台上;试样如是小径钻头,可横放在事先备好的V型支架上。调正试样,使其轴线与横向滑板的移动方向一致。 3.转动目镜框作视度调节,直到分划板上的
Impregnated drill bit diamond blade amount, refers to the drill bit in the diamond diamond exposed part of the top, with the root of the surface of the carcass height difference. The size of the blade directly affects the life of the drill bit and drilling speed. Therefore, studying the amount of diamond blades and related factors, the rational design of the drill, the correct choice of drilling parameters, are of great significance. Diamond cutting edge test method First, the sample preparation For large diameter drill, the vertical lip can be cut part of the fan-shaped blocks, and both sides of the cross-section polished, made of the sample. Drills smaller than 47 mm in diameter can be measured directly. Second, the test instrument JGX-1-type small tool microscope. Third, the test method 1. The instrument installed and commissioned as required. 2. The fan-shaped block specimen horizontal placed on the measuring stage; sample is small-diameter drill, can be placed on the cross-V prepared in advance on the stent. Adjust the specimen so that its axis coincides with the direction of movement of the cross slide. 3. Turn the eyepiece frame for sight adjustment until it is on the reticle
