る。 Since it is a non-metallic hard material, it is difficult to increase the cutting accuracy, and if you try to improve the machining accuracy in cutting, the material must be made of a higher quality, which increases the cost, so tighten the inclined surfaces. By making them close together, processing accuracy is compensated for, and by configuring the inclined surface a, the direction of the impact load is changed, thereby compensating for the drawback of non-metallic hard materials that they are easily broken by impact loads.
