What is a Inside micrometer?

The internal micrometer is a highly precise measuring instrument primarily used for measuring fine dimensions such as internal diameters and depths. Similar to a standard micrometer, it is designed to ensure accurate measurements of very small values, but its precision is even higher, typically achieving accuracy down to 1 micron (1/1000 millimeter).

An internal micrometer features a cone-shaped tip specifically designed for insertion into the internal surfaces of objects, allowing for direct measurement. Its application is particularly crucial in industries where the manufacturing of precision components requires stringent tolerances, such as in the aerospace and automotive sectors.

This device usually offers both analog and digital display options, making it easy for users to read measurement results. Internal micrometers are indispensable tools in quality control for precision instruments and are widely used in various fields, including research and development.

Application of Inside micrometer

１．Precision Manufacturing: In a factory that produces aerospace components, an internal micrometer is used to measure the inner diameters of tubular parts to ensure they meet strict specifications for assembly.
２．Quality Control: During the quality inspection process of automotive parts, an internal micrometer is utilized to verify the depth of threaded holes, ensuring they conform to required tolerances.
３．Research and Development: In a laboratory setting, engineers use an internal micrometer to measure the internal features of prototype devices, allowing for precise adjustments and enhancements in design.
