Detailed Installation Guide and Precautions for Marble/Granite Precision Platform Components

The installation process of Marble/Granite precision platform components must strictly follow specifications to ensure their accuracy and stability. The following are detailed installation steps and precautions:

I. Pre-installation Preparations

1. Site and Environmental Requirements

• Space Conditions: The installation site should be spacious to facilitate component handling and installation operations, with no strong vibration sources (such as stamping machines, large motors, etc.) around to avoid affecting accuracy.

• Ambient Temperature: The ideal temperature is 20±2℃, and the temperature fluctuation must be controlled within ±0.5℃/h to prevent Marble/Granite from deforming due to thermal expansion and contraction.

• Cleaning Requirements: The site must be cleaned in advance, with no dust or oil stains on the ground to avoid impurities affecting the component placement accuracy.

2. Tools and Materials Preparation

• Measuring Tools: High-precision level (accuracy ≤0.005mm/m), dial indicator, laser interferometer (for high-precision calibration).

• Support Components: Shock-absorbing support feet (usually metal with leveling function), support pads (hardness lower than Marble/Granite, such as rubber or nylon).

• Auxiliary Tools: Wrenches, feeler gauges, dust-free cloths, alcohol (for surface cleaning).

3. Component Inspection

• Check whether the Marble/Granite platform surface has defects such as cracks or chipping. Use a dial indicator to measure the flatness of the working surface to ensure it meets the factory accuracy requirements (e.g., flatness of grade 00 platform ≤0.005mm).

• Verify that accessories such as support feet and connectors are complete and undamaged.

II. Installation Steps

1. Installation of Support Structure

• Determine Support Point Positions: Mark the installation positions of support feet according to the platform size, weight, and design drawings (usually evenly distributed to avoid stress concentration). For example, a 1000mm×1000mm platform can have 4-6 support points, and large platforms require more support points.

• Install Support Feet:a. Place the support foot base at the marked position and initially level the base with a level (error ≤0.1mm/m).b. Connect the support foot body to the base and tighten the fixing bolts to ensure the support foot is perpendicular to the ground.

2. Positioning of Platform Main Body

• Handling and Placement:

◦ Use special lifting equipment (such as vacuum suction cups) to handle the platform to avoid collisions or deformation caused by manual handling.

◦ Gently place the platform on the support feet, ensuring the platform edges align with the center of the support feet to avoid overhang.

• Temporary Fixing: Slightly fix the platform to the support feet with temporary connectors (such as pressure plates) to prevent movement.

3. Rough Leveling

• Use a level to measure the horizontal and vertical directions of the platform working surface, and adjust the platform level by rotating the leveling bolts on the support feet.

• Rough adjustment target: Levelness error ≤0.05mm/m to ensure no obvious tilting.

4. Precision Calibration (Key Step)

• Flatness Calibration:c. Fix the dial indicator on a magnetic base, move the base in a grid pattern (e.g., 200mm×200mm spacing) along the platform working surface, record readings at each point, and draw a flatness error map.d. According to the error data, fine-tune the height of support feet: lower the corresponding support foot for bulges and raise it for depressions, adjusting repeatedly until the flatness meets the requirement (e.g., ≤0.005mm for grade 00 platform).

• Fine Leveling:

◦ Use a laser interferometer or high-precision level to measure multiple times along the platform diagonals and horizontal/vertical directions, fine-tuning support feet to make the levelness error ≤0.01mm/m.

◦ Pay attention to the mutual influence of support points during adjustment to avoid overall deviation caused by local adjustments.

5. Fixing and Vibration Damping Treatment

• Final Fixing: After confirming the accuracy meets the standard, tighten the fixing bolts between the support feet and the platform, ensuring uniform force to avoid platform deformation.

• Vibration Damping Measures:

◦ Install damping pads (such as rubber or spring dampers) at the bottom of support feet to reduce external vibration.

◦ If installed on a floor, lay a damping concrete foundation between the support feet and the ground to enhance stability.

6. Cleaning and Protection

• Wipe the platform surface with a dust-free cloth dipped in alcohol to remove oil stains and fingerprints left during installation.

• Install protective rails or dust covers to prevent hard object collisions or dust accumulation.

III. Installation Precautions

1. Stress Release: The Marble/Granite platform must stand for at least 24 hours after installation to allow full stress release before final precision calibration.

2. Avoid Temperature Difference Effects: Do not directly touch the platform surface with hands during installation to prevent local thermal deformation caused by body temperature; if the ambient temperature changes, wait for the temperature to stabilize before adjusting the accuracy.

3. Uniform Force on Support Points: Ensure each support foot is uniformly stressed during adjustment, and use a feeler gauge to check the fit clearance between the support pad and the platform bottom (≤0.01mm).

4. Regular Calibration: Record initial accuracy data after installation, and calibrate regularly every 3-6 months during use. If accuracy decreases, adjust the support feet in a timely manner or contact professional personnel for maintenance.

IV. Common Issues and Solutions

Following the above steps and precautions ensures the installation accuracy and stability of Marble/Granite precision platform components, meeting high-precision measurement or processing requirements. For large or special-specification platforms, professional on-site guidance is recommended.
