Marble inspection platform , also known as marble platform, granite platform, granite slab, marble measurement platform, granite measurement platform, granite measurement platform and so on. The natural stone is machined and hand-finished by a precision benchmarking tool. Because of its high accuracy and stable physical and chemical properties, it is mostly used as a marble inspection platform , and it can also be used as a basic workbench for high-precision instrument optical instruments. If you don’t know much about marble yet, come with me to learn more about the marbles!
The formation of a marble platform
The marble platform is based on high-quality rock layers in the underground, and after hundreds of millions of years of natural aging, the form is extremely stable and there is no need to worry about deformation due to the normal temperature difference. After strict physical tests and selection of granite, crystal fine, hard texture, compressive strength of 2290-3750 kg / square centimeter, hardness of Mohs hardness of 6-7. Extremely wear-resistant, acid-resistant, alkali-resistant, highly resistant to corrosion, never rusting. Due to the non-metallic material of marble, there is absolutely no magnetic reaction and no plastic deformation. Its hardness is 2-3 times higher than cast iron (equivalent to HRC>51), so it has good accuracy retention. In use, even if rock tools are bumped by heavy objects, they will lose a few grains of stone at most, instead of destroying the accuracy due to deformation. It is superior to precision measurement reference parts made of high-quality cast iron and steel, and can obtain high and stable accuracy.
Marble platform origin
Marble materials required for marble platforms Domestically, there are stones of this material in Shandong and Inner Mongolia. Among them, Shandong has the best material, Inner Mongolia has no comparison with Shandong, and marble platform's main producing areas are in Botou and Shandong Gaotang. .
Marble platform advantages
The marble platform is made of high-quality natural marble material through mechanical processing and hand-finishing. Black gloss, structure, fine texture, good stability. High strength and high hardness. And has: no rust, acid and alkali, no magnetization, the same type, good wear resistance. Can maintain stability under heavy load and general temperature.
The marble platform is a precise benchmarking tool made of natural stone materials. It is an ideal reference surface for inspection of instrumentation, precision tools, and mechanical parts. Especially for high-precision measurement, due to its unique characteristics, the cast iron plate dwarfs.
Granite slabs, precision granite slabs, and granite inspection slabs and instrument platforms are made of high-quality "Jinanqing" stone by mechanical processing and hand-finishing. Black gloss, precision structure, uniform texture, good stability, high strength, high hardness, can maintain high precision under heavy load and general temperature, and has no rust, acid and alkali resistance, abrasion resistance, no magnetization, invariable type And so on. Granite slabs are suitable for measuring tools in mechanical factories.
Marble platform features
The marble platform is mainly characterized by stable accuracy and easy maintenance. This is because:
1 The marble platform has a dense structure, a smooth surface and wear-resistance, and a small roughness value;
2 After a long period of natural aging, marble has completely disappeared internal stress, the material is stable and will not be deformed;
3 acid, alkali, corrosion, anti-magnetic;
4 will not rust rusty, easy to use and maintain;
5 linear expansion coefficient is small, affected by the temperature;
6 When the work surface is hit or scratched, only pits will be generated, no ridges or burrs will be produced, and there will be no effect on the measurement accuracy.
The main disadvantage of rock slabs is that they cannot withstand excessive impacts, knocks, high humidity, deformation, and moisture absorption of 1%. Marble platform working surface requirements:
The surface of the marble platform shall have no defects such as sand holes, shrinkage, scratches, bumps, pores, cracks, slag rust, etc. which will seriously affect the appearance and performance of the work. The depressions or corners on the non-working surface of the marble platform allow repairs.
Marble detection platform
The standard inspection tool for the marble inspection platform is the electronic level meter, but this kind of instrument is expensive, few customers can equip it, and then it is tested with a dial gauge and dragged with a magnetic meter seat; then the laser range finder is The accuracy of the detection method invented by one of our customers is very high; some customers use the three-coordinates to check the flatness of the marble platform. This is actually a wrong practice. After research proves that the three-coordinate is only suitable for checking the flatness and Parallelism double-sided precision marble platform products; 00 stone detection platform needs to be tested in a constant temperature room, otherwise it will affect its accuracy error.
Before placing and adjusting the marble platform, by changing the heights of the three supporting points, the marble platform is roughly adjusted to the horizontal level by the level meter, so that the load of the flat plate is evenly distributed on each fulcrum. The increased supporting points of the large flat plate need to be cushioned and the horizontal surface cannot be damaged. With the level meter check, the marble platform itself is the measurement base surface, and its placement should be stable; with the auto-collimator inspection, the instrument and the flat panel are not on the same rigid body. The instrument stand firmness is particularly important. Therefore, the verification procedure requires that the verification site should be firm Stability, verification site should avoid vibration. This is because: the factory often put a small flat plate on the bench or table, poor stability and stability. The tester moves around the plate, the test tool moves on the plate, will produce different gravity The space position of the flat plate is changed, and the measurement result is unreliable. Therefore, when the flat plate is tested, the flat plate should be moved to a firm and stable site to avoid influence of gravity change on the measurement result.
For the movement of the verification personnel on the large marble platform, the stability of the verification site should be considered, and the effect of gravity change should be taken into account. For small plates below 400mm×400mm, especially rock plates, the plates are lighter in weight and certified. The tools (level gauges or reflectors and bridges) are heavy. When they are placed in different positions, the load on the three fulcrums of the flat plate will change unevenly, resulting in contact and deformation between the flat plate and the support. In addition to the timing, the verification location should be considered stable. In addition, the weight of the test tool should also be noted. If necessary, additional support should be added to enhance the firmness of the flat plate. The accuracy of the marble platform is guaranteed.
Marble platform maintenance
1. In the daily use of the marble platform, it is inevitable that there will be some areas that cannot be noticed. We must develop a habit of regular maintenance. Generally speaking, this cycle is so small that it needs to be checked and cleaned up every day, and it is necessary to focus on conservation once a week. After each use of the marble platform, clean the workbench. If there is any stain, clean it in time. When cleaning, wipe the cloth with alcohol to keep the marble platform clean and tidy. It is important.
2. After using the marble platform, we must remember to use a protective cloth cover on it, so that falling debris will fall on it. Be careful not to bump the platform when working, so as not to affect the next measurement and use. The surface of the clean marble platform is best cleaned with a neutral detergent to prevent corrosion of the worktable. It is also used in accordance with the operating specifications. It has reached the maximum working life of the working platform, reducing the cost of the enterprise, and at the same time developing this After the habit can also maximize the quality of work.
Editing summary: If ink droplets do not permeate, the water absorption is low. However, usually the marble platform surface is generally coated with a protective agent to prevent the penetration of stains. Sometimes we see that the ink droplets do not penetrate and may be a protective agent, not necessarily the performance of the marble platform itself. In general, the marble platform has a low water absorption rate, and the change of the humidity during use does not easily destroy the accuracy of the marble. Therefore, it can be said that the smaller the water absorption rate of the Dali plate is, the better the marble material is.
