marble platform

Measurement method and use of marble platform:

The blank of the marble platform is first cut into the required size using a diamond circular saw blade. The machined surface usually goes through several processes of grinding and polishing with grinding wheels, and is manually ground using gray cast iron grinding tools and silicon carbide abrasives. When slotting, use the corresponding milling head, and when drilling, use a diamond core drill bit.

There are two methods for its detection: one is to use an electronic level with an accuracy of 0.5 μ m, which can detect straightness using displacement method and detect flatness using displacement method. The measured results are converted through algorithms to obtain specific values for straightness and flatness; Its characteristic is that the accuracy is not very high, but the measurement data is missing; 0' The problem of point drift is particularly suitable for online measurement and detection.

Another method of measuring straightness can be achieved by using a displacement method with a capacitance micrometer with an accuracy of 0.1 μ m, and the reading on the meter head is the error value of straightness; In this measurement, due to the inherent characteristics of the inductive micrometer; 0' The point drift is severe and requires a stable period of up to 24 hours for its value to be reliable, which increases the connection time between processing and measurement. Precision machining has precision detection methods. Currently, HP5528A or HP5529A dynamic calibrators are commonly used, with a display accuracy of 1nm. They can detect flatness, perpendicularity, straightness, time base, vibration, angular displacement measurement, diagonal measurement, and so on.

To achieve the measurement effect of marble slabs, it is necessary to pay more attention to the relevant issues during daily operation of the marble platform, especially in the maintenance process.

When operating on a marble platform, special attention should be paid to the handling and placement of the workpiece, and special care should be taken not to collide with the platform, as even small impacts may affect the measurement. Any defects should be promptly addressed.

2. The marble platform should always be kept clean, and the flat surface should not be damaged by impurities such as iron filings and sand.

To avoid deformation of the marble platform, the workpiece should generally be lifted down after inspection or marking, and should not be placed on the flat plate for a long time.

4. After use, it is necessary to take some time to clean the marble platform surface, promptly wipe off the working surface of the platform, and then apply a layer of rust proof oil. If it is determined not to use within the specified time, apply a layer of butter and then spread a layer of white paper. The casting of machine tool bed should undergo periodic inspection, and the inspection cycle should be determined according to the specific frequency of actual use, generally 1 year.

The use of a marble platform has a decisive impact on the measured values and directly affects the service life of the marble platform, so the operation is crucial.
