The 3D marble platform is mainly used for high-precision 3D printing and precision measurement. Its high flatness and stability ensure accurate printing process, and it is also used as a measurement reference surface in fields such as machine tool inspection and equipment installation accuracy testing.
core functionality
3D printing support: Improve printing accuracy through high flatness and stability, withstand load impact without deformation, and ensure the quality of printed parts.
Precision measurement benchmark: used for dimensional accuracy detection in mechanical processing, calibration of machine tool straightness/unevenness, and calibration of instruments and meters.
The flatness inspection of the 3D marble platform is based on the ideal plane of the flat working surface, which is compared with the actual surface being measured to determine the size of the error. The common methods are as follows.
1. Coloring method: Coloring method is used to test flatness by using a flat plate as an ideal plane and coating it with red lead powder. Then, the tested surface is attached to it, and after back and forth grinding, the tested surface is removed to observe the distribution of red lead powder attached to the tested surface. The flatness of the tested surface is judged by the number of (25 × 25) mm coloring points.
When inspecting, the flatness error value of the selected inspection plate must be three to five times higher than the flatness error required by the side, otherwise the inspection result is unreliable.
The advantage of coloring method is that it is simple and easy to operate. The disadvantage is that it can only determine whether the tested surface plane is qualified or not, and cannot measure its specific value.
2. Marking method: Marking method is to place the measured workpiece and indicator on a reference flat plate, that is, to use the reference flat plate as the ideal plane. When measuring, the indicator should be moved point by point or several straight lines against its reference plate to measure the flatness error value of the measured surface.
Precautions for use
Environmental control: Avoid direct sunlight and drastic temperature changes. It is recommended to maintain a constant temperature environment (temperature fluctuations ≤ 1 ℃/h).
Cleaning and maintenance: Regularly wipe with a dust-free cloth to avoid using corrosive cleaning agents; Professional lifting equipment is required during transportation to prevent collisions.
Accuracy testing: Use a laser interferometer or electronic level to test the flatness every six months to ensure long-term stability.
