Marble detection platform is a precision benchmark platform made of natural granite (such as Jinanqing, Mount Taishan Green) or synthetic marble, which is mainly used for dimensional measurement, shape and position tolerance detection and precision assembly of workpieces. Its core advantages include:
High precision stability: The flatness can reach 0.005mm/m (level 00), and the benchmark remains unchanged for a long time;
Anti environmental interference: The thermal expansion coefficient is only 1/3 of cast iron, suitable for constant temperature and humidity environments;
Low friction characteristics: The working surface roughness Ra is ≤ 0.4 μ m, reducing tool wear.
Classification and Characteristics of Marble Testing Platforms
1. Standard marble platform
• Structure: Smooth surface without grooves, bottom surface with supporting ribs;
• Applicable scenarios:
Laboratory precision measurement (such as gauge block calibration, coordinate measurement);
Flatness detection of optical components.
2. Marble platform with T-shaped groove
Design: The top surface has T-shaped grooves (such as 12mm × 12mm) with a spacing of 50-100mm;
• Features:
Fast installation of compatible fixtures and pressure plates;
Suitable for detection scenarios that require multi station positioning (such as gear tooth profile detection).
3. Marble platform with threaded holes
• Structure: evenly distributed M6-M16 threaded holes (spacing 50mm);
Locking method: fix the adapter plate or sensor bracket with bolts;
• Typical applications:
Installation and positioning of electronic components;
Multi directional detection of micro workpieces.
4. Combination marble platform
Function: Multiple small platforms are spliced together to form a large reference surface (up to 3m x 6m);
• Advantages:
Flexible expansion of detection range;
The built-in leveling mechanism compensates for splicing errors.
Installation and adaptation of marble detection platform
Installation method
1. Basic requirements:
Installed in a constant temperature and humidity environment (temperature 20 ± 2 ℃, humidity 40-60%);
Use shock absorbers or air springs to isolate vibrations.
2. Fixed method:
The bottom is connected to the foundation through expansion bolts;
When assembling multiple platforms, alignment pins are required.
Adaptation suggestions
• Compatibility of measuring tools:
Equipped with high-precision measuring tools such as micrometers, level gauges, laser interferometers, etc;
Avoid using magnetic tools (marble is non-magnetic).
• Workpiece adaptation:
Large workpieces require support blocks to disperse pressure;
◦ Precision testing recommends platforms with V-shaped grooves (for cylinder positioning).
Selection and maintenance suggestions
Key parameters for selection
• Material:
Natural granite (hardness HS70-80, strong wear resistance);
Artificial marble (low cost, suitable for non precision environments).
Accuracy level: According to GB/T 20428-2006, it is divided into level 00 (± 0.005mm/m) and level 0 (± 0.01mm/m);
Surface treatment: mirror polishing (Ra ≤ 0.2 μ m) or matte treatment (reducing reflective interference);
Attachment options: customizable protective fence, leveling feet, or dust cover.
Maintenance points
1. Daily maintenance:
Use neutral cleaning agents and a soft cloth to wipe and avoid corrosion from acidic substances;
Regularly calibrate the flatness with a laser interferometer (recommended once a year).
2. Anti damage measures:
Do not strike or place heavy objects on the platform (single point load ≤ 100kg);
Use specialized hangers during transportation to prevent corner collisions.
