The use of marble platforms and cast iron platforms, classified and distinguished by material

Classification and differentiation of marble and cast iron platforms based on their uses and materials

1. Usage classification

(1) Marking platform: a reference plane used for marking operations.

(2) Assembly platform: It serves as a foundation for mechanical installation, or a temporary foundation for assembly adjustment and test drive, or a temporary foundation for assembly adjustment and test drive.

(3) Inspection platform: a reference plane for inspection or measurement.

(4) Platform for tapping: A work surface used for tapping sheet metal operations.

2. Classify by material

(1) Cast iron platform: made of cast iron, with reinforcing ribs below the platform to reduce weight and enhance its strength; The countertop needs to undergo JINGMI grinding or scraping procedures. Its advantages (properties) are:

1. Good shock absorption.

2. Good lubricity.

3. NAIMOXING is doing well.

4. Easy to process and shape.

5. The price is cheap.

Its disadvantages are:

1. After prolonged use, there are often scratches on the surface, which not only create depressions but also protrude on both sides of the scratches; If measuring tools are used on this surface, the base is often scratched.

2. Although the platform has been subjected to XIAOCHU stress for a long time, there may still be some warping due to the influence of surrounding environmental factors such as temperature and vibration, resulting in surface errors.

(2) Marble Platform; The surface is flat and smooth; Marble is produced in nature and its surface is polished and processed into a precise plane.

Its advantages (properties) are:

1. YINGDUGAO: The hardness of marble is about twice that of cast iron, and it has a long service life.

2. Less affected by temperature: Due to its coefficient of thermal expansion of approximately 1.05Kcal/m.h. ℃, which is much lower than the 45Kcal/m.h. ℃ of cast iron, it is less affected by temperature changes.

3. Non deformable: Marble is formed by the solidification of melted strata, and after long-term natural phenomena, the material is stable and not easily deformed.

4. No burrs or chamfers: After impact, the scratch particles become finer grains without affecting the flatness; The surface of the cast iron platform not only has depressions but also immediately forms raised burrs, damaging its flatness.

5. High corrosion resistance: The surface of marble does not rust and can resist 5% sulfuric acid. Its acid resistance is more than 57 times that of cast iron

6. NAIMOXING is about 7.5 times stronger than cast iron..

7. Not adhesive: Its surface has been polished, so it is smoother than JINGXI and will not stick to the measuring tools on it, so it slides smoothly.

8. Not reflective and dazzling: Due to its dull color, it is not dazzling and does not cause eye fatigue.

9. Easy to clean: Simply wash with water and soap, the surface of the platform will not fade or be damaged.

10. Easy maintenance: No need to add rust proof oil on the surface, reducing maintenance costs.

11. Non magnetic: Granite is an insulator, WANQUAN is not magnetic, and magnetic equipment can be used.
