取芯钻头原理

取芯钻头原理
English:
A core drill bit, also known as a hole saw, operates on the principle of removing a core of material from the workpiece being drilled. The core drill bit consists of a hollow steel tube with diamonds embedded on the cutting edge. When the core drill bit is rotated and pressed against the workpiece, the diamonds on the cutting edge grind away the material, creating a cylindrical hole. The core of material removed from the workpiece is referred to as the "core sample." This method is commonly used in construction, mining, and geological exploration to obtain samples of the earth's crust. The core drill bit can also be used to create holes in materials such as concrete, brick, and stone, making it a versatile tool for various applications.
中文翻译:
取芯钻头，也称为套孔钻头，其原理是从被钻孔的工件中移除物料的核心。

取芯钻头由一个带有切割边缘上镶嵌有金刚石的中空钢管组成。

当取芯钻头旋转并压在工件上时，切割边缘上的金刚石磨掉物料，从而形成一个圆柱形孔。

从工件上取下的物料核心称为“取芯样本”。

这种方法通常用于建筑、
采矿和地质勘探，以获取地壳样本。

取芯钻头还可用于在混凝土、砖和石材等材料中钻孔，使其成为各种应用的多功能工具。
