Bore Dial Gauge

 A bore dial gauge, also known as a dial bore gauge or bore gauge, is a precision measurement tool used to measure the internal diameter or bore of a cylindrical hole. It is commonly used in various industries, including manufacturing, engineering, and automotive applications.


The bore dial gauge consists of a measuring head or probe attached to a dial indicator, which displays the measurement on a dial face. The measuring head typically consists of two or three spring-loaded anvils or measuring arms that can be expanded or contracted to fit inside the bore being measured. The anvils make contact with the inner walls of the hole, allowing for an accurate measurement.


To use a bore dial gauge, the measuring head is inserted into the bore, and the anvils are expanded until they make contact with the inner walls. The dial indicator then displays the measurement, usually in units of thousandths of an inch (or millimeters). The user can then read the measurement from the dial face to determine the internal diameter of the bore.


One of the advantages of a bore dial gauge is its ability to measure both the size and roundness of a bore. By rotating the measuring head while taking measurements at different positions, it is possible to assess the concentricity and uniformity of the bore. This makes it a valuable tool for quality control and inspection purposes, ensuring that bores meet the required specifications.


Bore dial gauges come in different sizes and designs to accommodate a wide range of bore diameters. Some models have interchangeable anvils, allowing for flexibility in measuring various sizes of holes. They are typically made of high-quality materials such as hardened steel or carbide, ensuring durability and accuracy over time.


In addition to their use in manufacturing and engineering, bore dial gauges are commonly employed in automotive applications. They are used to measure the internal diameter of engine cylinders, ensuring proper fitment of pistons and rings. This helps maintain engine performance and efficiency.


Overall, bore dial gauges are essential tools for accurately measuring the internal diameter and roundness of bores. Their precision and versatility make them indispensable in a variety of industries, where precise measurements are crucial for ensuring product quality and performance.
