Granite inspection platforms are typically made of granite, with a surface precision-machined to ensure high flatness, hardness, and stability. Granite, a rock with excellent properties such as hardness, wear resistance, and stability, is suitable for manufacturing high-precision inspection tools. Granite platforms are widely used in industries such as machinery manufacturing, mold making, precision machining, and optical instrumentation, primarily for supporting, securing, and performing precise measurements to ensure the dimensional accuracy of parts and products.
The main features of granite inspection platforms are as follows:
1. Hard and wear-resistant material: Granite’s high hardness allows it to withstand significant pressure and impact, making it suitable for long-term, heavy-load inspections.
2. Excellent stability: Granite has a low coefficient of thermal expansion, maintaining high accuracy and resisting deformation even in environments with large temperature fluctuations.
3. Strong corrosion resistance: Granite has excellent corrosion resistance and is resistant to chemicals and oils, ensuring a long service life in industrial production.
4. Smooth surface: The finely machined granite platform’s smooth and flat surface provides a precise measurement reference, making it suitable for high-precision inspections. 5. Moderate weight and easy processing: Granite has a high density, so the platform is generally heavy, which helps reduce vibration interference with measurement results and increases operational stability. Furthermore, granite is easy to process, allowing it to be manufactured into inspection platforms of various sizes and shapes to meet specific needs.
Application Areas:
1. Machining Industry: In machining, granite is primarily used for dimensional inspection, assembly, and surface inspection of parts. Accurate measurement ensures that mechanical parts meet design requirements, improving processing accuracy and product quality.
2. Mold Manufacturing: Mold manufacturing requires extremely high precision, and granite provides a reliable reference surface for dimensional measurement, positioning, and assembly of mold parts, ensuring mold product accuracy.
3. Precision Instruments: Precision instruments such as optical and electronic instruments require granite platforms as a reference surface during production and inspection, enabling high-precision measurements and ensuring instrument accuracy and stability.
4. Quality Inspection: In various quality inspections, granite platforms can be used in various environments as a testing tool to measure product geometry, surface finish, and tolerances. Purchasing Guide:
1. Size Requirements: Select an inspection platform of appropriate size based on actual work needs. The platform should be larger than or equal to the size of the part being inspected and provide ample operating space.
2. Accuracy Grade: There are different accuracy grades, typically categorized as A, B, C, and D. The higher the accuracy grade, the better the platform surface flatness, making it suitable for more demanding inspection tasks. Select a platform with the appropriate accuracy grade based on actual use.
3. Surface Flatness: Platform surface flatness is one of the most important performance indicators of a granite platform. A good platform should have very precise surface flatness, providing a stable measurement reference.
4. Stability: The stability of the platform directly affects measurement results. When selecting a platform, consider its load capacity, wear resistance, and deformation resistance to ensure it will not shift or deform over time.
5. Material and Processing: The granite material determines the platform’s durability and measurement accuracy. High-quality granite should have a low coefficient of expansion, high hardness, and be free of cracks and impurities. The machining process of the platform is also crucial. The surface finish must be high and free of obvious defects.
6. Additional Features: Some platforms can also be equipped with additional features, such as precision leveling devices, digital displays, and air-floating supports, which can improve work efficiency and measurement accuracy.
Maintenance Measures for Granite Inspection Platforms:
1. Regular Cleaning: After use, the platform surface should be cleaned promptly to remove dust, oil, and other impurities to prevent these from affecting measurement accuracy.
2. Avoid Violent Impact: Although the surface is hard, severe impact can still cause damage or cracks. Therefore, care should be taken to avoid impact during use.
3. Keep Dry: Although granite has good corrosion resistance, excessive moisture can still affect its surface condition. Therefore, the platform should be kept dry and avoid prolonged exposure to humid environments.
4. Regular Calibration: Over time, the platform surface may show slight wear. Regular accuracy calibration should be performed to ensure that the platform still meets the required measurement standards.
