A micrometer is a precision measuring tool that achieves high-precision measurement through the precise thread matching of a screw and a sleeve. It is mainly used for dimension detection in the field of mechanical processing, with an accuracy of up to 0.01 millimeters. ‌

classification

Micrometers are divided intoElectronic digital displayformula Two categories. Mechanical measurement is based on the principle of spiral pair transmission, while electronic digital display supports wireless transmission, data locking and other functions, with higher accuracy. ‌

structural principle

The main body consists of a micrometer screw, a fixed sleeve, and a movable sleeve. When the screw rotates, it converts linear displacement into rotational motion through a threaded pair, and finally displays the measurement results through a dial. ‌

measurement range

The conventional measurement range is 0-150 millimeters, and different specifications of micrometers (such as 0-25mm, 25-50mm, etc.) can be adapted to different needs by replacing the micrometer head. ‌

Accuracy and Error

Mechanical micrometers typically have an accuracy of ± 3 micrometers, while electronic digital displays can achieve a resolution of up to 1 micrometer. During measurement, it is necessary to keep the object being measured parallel to the anvil to avoid errors caused by excessive force.
