What are the advantages of marble platforms compared to cast iron platforms

The main difference between cast iron T-shaped groove platform and marble T-shaped groove platform is the materials and processing methods used in their manufacturing. The cast iron T-shaped groove platform is a flat plate made of cast iron material.

The cast iron material used is fine-grained gray cast iron or alloy cast iron. The common processing method is the scraping method, and the scraped flat working surface can store lubricating oil and contain small dust particles in the pits, improving the stability of the benchmark.

After wear and tear, the T-shaped groove platform can be re scraped to restore its accuracy. The T-shaped groove platform can be used to inspect the flatness of parts using the coloring method, which has the advantages of accuracy, intuitiveness, and convenience. Pushing the gauge seat and workpiece smoothly on the scraped cast iron plate without any feeling of roughness facilitates measurement accuracy.

The cast iron quality and heat treatment quality of the T-shaped groove platform have a significant impact on the performance of the flat plate: or the working surface may deform due to residual large internal stresses; Or due to difficulty in scraping, roughness with small values cannot be obtained. Therefore, when using cast iron plates, pay attention to the selection of cast iron materials

Advantage:

The marble T-platform has a black luster, uniform texture, good stability, high strength, and can be maintained under heavy loads and general temperatures. It has the advantages of not rusting, not magnetizing, and being invariant. After long-term aging, the rock has a uniform organizational structure, linear expansion coefficient, and internal stress disappears without deformation. Marble T-shaped groove platform has good rigidity and minimal temperature deformation.

Marble T-shaped groove platform is not afraid of acid and alkali erosion, will not rust, does not need to be coated with oil, is not easy to stick to dust, easy to maintain, and has a long service life. The marble platform will not have scratches, is not hindered by constant temperature conditions, and can maintain temperature measurement accuracy at room temperature. The marble platform is not magnetized, and it can move smoothly during measurement without any roughness or being affected by moisture. The surface is properly weighed.
