Granite (marble) precision platform is a reference measurement and precision assembly base platform made of granite as the base material, which has been precisely processed and strictly inspected. With the excellent physical stability of the material itself, it has become the core basic component of high- manufacturing, metrology inspection, and precision equipment, with high precision, high stability, and long life as its core advantages, supporting the continuous improvement of industrial precision.
I Material characteristics: born stable, for precision
Extremely strong dimensional stability
The natural granite structure is dense and has low internal stress, which hardly produces plastic deformation under normal temperature conditions does not warp or deform over long-term use, and ensures lasting and reliable reference precision.
Extremely low coefficient of thermal expansion
It is affected very little by temperature changes and compared to metal platforms, the dimensional error caused by temperature fluctuations can be negligible, especially suitable for high-precision measurement and detection scenarios.
It does not rust, is-resistant, and wear-resistant
It is not corroded by acid, alkali, oil, water, and other media, does not rust, does not magnetize, does conduct electricity, and has strong adaptability to the use environment and simple daily maintenance.
Smooth surface, not easy to scratch the workpiece
After precise grinding and pol, the surface has high glossiness, uniform and hard texture, which can ensure measurement accuracy and is not easy to damage precision workpieces and measuring tools.
II. Core advantages
High flatness/straightness precision
It can achieve high-level precision such as 00 grade, 0 grade, K grade (laboratory reference grade, etc., meeting the full-scene precision needs from the workshop site to the metrology room.
No internal stress, no rebound, no warpage
After sufficient aging, internal stress is eliminated, and no deformation will occur during use due to force, time, and environment.
Stable and reliable measurement reference
As a planar reference, vertical, and angular reference, it can be used with equipment such as differential indicators, percentage indicators, height gauges, projectors, etc., to complete high-precision testing,, assembly, and marking.
III. Environmental adaptability and control points
Small temperature effect
Suitable for use in constant temperature workshops (20℃±2℃, and can still maintain far superior stability to metal platforms in ordinary environments.
Humidity control is key
The plate itself is not affected by humidity, but high humidity can cause rust on accessories, surface dew, and increased measurement errors, and it is recommended that the relative humidity of the environment be 40%～60%.
ong anti-interference ability
It is not easily affected by vibration, magnetic field, slight collision, etc., to ensure stable and reliable measurement and assembly process.
. Typical application scenarios
Precision parts flatness, parallelism, and verticality testing
Calibration and inspection benchmark for tools, gauges, and instruments
Prec machine tool, automation equipment, optical instrument installation benchmarking table
Mold, aerospace, semiconductor, 3C electronic and other high-precision manufacturing and testing
Standard benchmark for metrology laboratories
V. Usage and maintenance advantages
No need for rust prevention treatment, just dust prevention, moisture prevention, and protection from severe impact
Precision not deteriorate over long-term use, and the service life is far longer than metal platforms
Low maintenance cost, easy cleaning, and suitable for long-term continuous operation
In summary:
Granite platforms are based on material stability, guaranteed by precision processing, and aimed at long-term reliability. They are the core carrier of “precision and” in industrial manufacturing and provide irreplaceable reference support for high-precision measurement, assembly, and calibration
