Application of wire grain scale in measurement and detection

First, the basic overview of the line rule

Line ruler is a length measurement and positioning element made of metal or glass and accurately engraved with equal spacing parallel lines on the surface, also known as line ruler. It is mainly divided into three categories: reference line grain scale, standard line grain scale and working line grain scale. The reference line grain and standard line grain are mainly used for the transmission of the measurement value of the length measurement to ensure the accuracy and consistency of the measurement results. The working line gauge is widely used in various measuring instruments and precision machine tools, as a key component of measurement and positioning.

Second, the application of line rule in measurement and detection

Calibration elements in length measuring tools:

Working line gauge is used as a key element in measuring and calibrating optical components in length measuring tools such as length comparator, length measuring machine, universal tool microscope and universal measuring machine. It is used in conjunction with the reading microscope, optical reading head or photoelectric microscope in these tools to achieve accurate measurement of the object under test.

Positioning elements in precision machine tools:

In the precision machine tools such as jig boring machine and coordinate grinding machine, the working line rule is used as the optical positioning element to ensure the high-precision positioning in the machining process of the machine tool. This is of great significance for improving machining accuracy and ensuring product quality.

Quantity transfer and calibration:

The reference line grain and the standard line grain play a key role in the transfer of the value of the length measurement. They serve as a standard for calibrating other measurement tools, ensuring accuracy and consistency throughout the measurement system.

Other applications:

Line scale is also widely used in surveying and mapping science, remote sensing precision measurement and other fields, which provides a strong support for scientific research and technical progress in these fields.

Third, the precision and error control of the line rule

The precision of linear grain scale is an important index to measure its measuring accuracy. Different types of wire rule have different accuracy requirements. For example, the allowable calibration error of the reference line grain is ±0.2 micron /1000 mm; The accuracy of the working line grain can reach ±1 micron /1000 mm or higher. In order to ensure the accuracy of the wire rule, it is necessary to carry out regular verification and calibration, and find and correct errors in time.

Iv. Summary

To sum up, the wire scale plays a vital role in measurement and detection. It is not only used as calibration element in length measuring tools and positioning element in precision machine tools, but also widely used in quantity transmission and calibration and other scientific research and technology fields. In order to ensure the accuracy and reliability of the wire rule, it is necessary to strictly control its accuracy and error, and carry out regular verification and calibration work.
