Marble ruler manufacturerPrecision testing is a professional and meticulous process that mainly involves measuring key indicators such as flatness and perpendicularity. The following are the general steps and methods for precision testing of marble rulers:

1、 Preparation for testing

Environmental requirements: Ensure a stable testing environment, free from interference factors such as vibration and temperature changes, to ensure the accuracy of the testing results.

Tool preparation: Prepare high-precision measuring tools such as optical parallelizers, vernier calipers, photoelectric micrometers, micrometers, etc. These tools need to be calibrated to ensure their accuracy meets the testing requirements.

2、 Static detection method

Place a ruler: Place the marble ruler on a horizontal plane to ensure its stability and stability.

Check parallelism: Use an optical parallelizer to check if the surface of the marble ruler is parallel to the horizontal plane. By adjusting the angle and position of the optical collimator, small deviations of the ruler surface can be observed.

Measurement error: Use a vernier caliper to measure the length of the ruler along its surface and record readings at multiple measurement points. Then, calculate the error value of the entire marble ruler according to national standards.

3、 Dynamic detection method

Straightening ruler: Straighten the marble ruler along its length to ensure that it does not deform during the measurement process.

Measuring height differences: Use high-precision measuring instruments such as photoelectric micrometers to measure the height differences at different positions on the ruler surface. These differences reflect the unevenness of the measuring surface.

Calculate the error value: Based on the height difference data obtained from the measurement, calculate the error value of the marble ruler.

4、 Verticality detection

Place a flat ruler and a square ruler: Place a marble flat ruler on a flat surface with one side in contact with a standard square ruler.

Installation of dial gauge: Install a gauge holder with a division value of 0.001 millimeters on the dial gauge and fix it on a standard square ruler with a standard round rod.

Reading: Place the dial gauge holder close to one side that is level, and the reading of the dial gauge is the perpendicularity error of that side. Similarly, detect the perpendicularity error of the other side and take the maximum error as the final result.

5、 Precautions

Avoid damage: During the testing process, it is necessary to avoid external force damage to the marble ruler to avoid affecting its accuracy.

Regular calibration: Regularly calibrate measuring tools to ensure their accuracy meets the testing requirements.

Recording data: Detailed recording of various data during the testing process for subsequent analysis and processing.

In summary, the accuracy testing of marble rulers needs to follow certain steps and methods, and pay attention to relevant matters to ensure the accuracy of the testing results. Through professional testing methods and techniques, it is possible to evaluate whether the accuracy level of the marble ruler meets the requirements for use.
