Cast Iron Material Properties: The graphite structure within cast iron acts like a natural shock absorber, effectively absorbing vibrations and impacts generated during processing and reducing their impact on processing precision. At the same time, the high hardness and wear resistance of cast iron make it resistant to wear during long-term use, maintaining the precision of the platform's reference surface.

Platform Structural Design: Scientific rib layouts and box-type structural designs greatly enhance the rigidity and load-bearing capacity of the platform. This structural design can evenly distribute load pressures, allowing the platform to remain stable and resistant to deformation even under heavy loads.

2.3 Classification of Mainstream Products

Classification by Precision Grade: It covers multiple precision grades such as Grade 0, Grade 1, and Grade 2. Grade 0 has the highest precision and is suitable for ultra-precision measurement and calibration. Grade 1 meets the high-precision processing requirements of precision instrument manufacturing. Grade 2 is suitable for general mechanical processing and assembly operations.

Classification by Usage: It includes measuring platforms, scribing platforms, assembly platforms, etc. Measuring platforms emphasize high-precision flatness and are used for accurate measurement of workpiece dimensions. Scribing platforms highlight the wear resistance of the working surface to facilitate scribing operations on workpieces. Assembly platforms focus on strong load-bearing capacity to support the assembly of large components.

2.4 Analysis of Key Technical Parameters

Flatness: Flatness is a key indicator for measuring the precision of a cast iron platform, reflecting the flatness of its working surface. The higher the flatness, the more precise the reference provided for the workpiece, and the smaller the processing error.

Load-bearing Capacity: Load-bearing capacity is determined by the material, structure, and size of the platform, indicating the maximum weight the platform can withstand. In actual use, it is necessary to select a platform with an appropriate load-bearing capacity according to the weight and force conditions of the processed workpiece to ensure safety and stability.

Hardness: Appropriate hardness enables the cast iron platform to effectively resist friction and impacts from workpieces while facilitating precision repair when necessary. The hardness index directly affects the service life and maintenance cost of the platform.

III. Core Functions of Cast Iron Platforms in Mechanical Processing

3.1 Providing a Stable Reference to Ensure Processing Precision

In mechanical processing, precision is the lifeline of product quality. Cast iron platforms, with their high flatness and stable performance, provide precise reference surfaces for measuring tools. Whether using a dial indicator to measure the geometric tolerances of workpieces or a caliper to measure dimensions, cast iron platforms can ensure the accuracy of measurement results, thereby providing a reliable basis for subsequent processing, effectively controlling processing errors, and guaranteeing product precision.

3.2 Supporting Workpieces and Complex Processing Operations

During mechanical processing, the clamping and processing of workpieces require stable support. The strong load-bearing capacity of cast iron platforms can withstand the weight of heavy workpieces and the cutting forces generated during processing. In processes such as milling and grinding, the platform provides a stable support for workpieces, allowing the processing equipment to operate smoothly, ensuring the smooth progress of the processing process, and also contributing to improving the service life of the equipment.

3.3 Assisting in Workpiece Positioning and Fixing

The surface of a cast iron platform is designed with T-slots, bolt holes, etc., enabling it to be used in conjunction with various types of tooling fixtures to achieve rapid positioning and firm fixing of workpieces. In batch processing or the processing of complex workpieces, precise positioning and fixing can reduce the clamping time of workpieces, improve production efficiency, and also ensure the processing consistency of workpieces in the same batch.

3.4 Shock Absorption to Reduce Equipment Wear

Processing equipment generates vibrations during operation. These vibrations not only affect processing precision but also accelerate the wear of the equipment. The shock-absorbing properties of cast iron platforms can effectively buffer the vibrations generated by processing equipment, reducing their impact on the equipment and workpieces. This not only helps to improve processing quality but also extends the service life of processing equipment, reducing the enterprise's equipment maintenance costs.

4.2 Scribing Operation Scenarios

In the preliminary preparation stage of mechanical processing, scribing platforms play an important role. Technicians use tools such as scribing needles and height gauges on scribing platforms to draw processing contour lines, center lines, etc., on the workpiece surface according to design drawings. The wear resistance and good flatness of the scribing platform's working surface ensure the accuracy of scribing, providing clear guidance for subsequent processing.

4.3 Component Assembly Scenarios

In the assembly process of mechanical products, assembly platforms are used to support and fix components, ensuring the accurate relative positions of various parts.
