Counterbore 是一个工程和机械术语,指的是一种钻孔方法,用于在工件上制作一个具有较大直径的、与原孔相接的圆形凹槽,通常用来容纳一个螺钉头或其他紧固件,使其平齐或稍微低于工件表面。

Counterbore的音标:

英音:/ˈkaʊntəbɔːr/
美音:/ˈkaʊntərbɔːr/

Counterbore的翻译:

中文翻译:铣孔,倒孔,沉头孔

定义:是指在已有孔口上扩大孔口的直径,通常用于配合某种紧固件。

Counterbore的用法:

在机械加工中,Counterbore常用于使螺钉头部能够嵌入工件表面,避免其突出。这样可以确保螺钉或螺栓的头部与工件表面齐平,从而提高设备的安全性和美观度。

例句:

The technician used a counterbore tool to create a recess for the bolt head.

The counterbore was designed to hold the screw head below the surface of the material.

A counterbore is often necessary when installing a flush-mount fastener.

The machinist carefully drilled a counterbore to ensure a perfect fit for the component.

The new design required a counterbore to accommodate a larger fastening element.

A counterbore tool was inserted into the drill press to make the required recess.
