Precautions for using marble slabs

Apr 15,2024

Precautions for the Use of Marble Platform The use of marble platform should protect the operation of dedicated service personnel, pay attention to observe the subtle changes after each use, conduct technical communication with manufacturers in a timely manner, and make amendments and reasonable plans. Do not affect the service life of the platform due to small losses.

Inspection before use:

1. The platform shall be provided with qualified marks, excellent service life or other certificates.

2. The measuring surface of the marble platform shall be free of burrs, scratches, bumps, rust and other defects that affect the measurement results.

3. The tested part of the tested part shall be free of burrs, scratches, bumps, scratches, rust and other defects.

The temperature of the marble platform and the measured piece should be as consistent as possible to prevent measurement errors.

5, before use, should be checked according to the specified requirements and methods, qualified before use.

Marble platform in the natural temperature measurement matters needing attention

When the marble platform is measured at natural temperature, the measurement error caused by the change of temperature is also very common. Here are some precautions for everyone;

1. The flatness of the working surface of the marble platform ranges from 3μm-15μm, which is generally used in the laboratory, and the working temperature is 20 ℃ ± 2 ℃. However, due to certain factors, it is also commonly used in manufacturing plants at natural temperatures.

2, the installation position of the marble platform should avoid sunlight, away from the heat source and vibration environment.

3, because the marble platform and the measured workpiece have different thermal expansion coefficients, when the temperature changes, they usually extend or shrink in different proportions. If you believe the measurement results, they will drift over time, but they will be affected by the relative size. Large parts. Therefore, the measurement should be repeated several times at different time difference temperatures to compare the measurement results.

4, in a few weeks as long as the repeated measurement and recording of the same parameter of the workpiece, it is easy to determine the change in measurement accuracy caused by temperature changes, the use of a thermometer can also record the ambient temperature of each measurement, compare these measurements, you will see their differences.

Nothing!
