Against the backdrop of the rapid development of Industry 4.0 and intelligent manufacturing, 3D intelligent measuring instruments, as the core equipment for precise detection, have reached an unprecedented height in terms of measurement stability and accuracy. The ZHHIMG granite platform, with its natural material advantages and exquisite processing techniques, has become a key supporting component for 3D intelligent measuring instruments to achieve high-precision measurement, providing reliable guarantees for quality control in fields such as semiconductor manufacturing, aerospace, and precision molds.
Ultra-low coefficient of thermal expansion, stable measurement reference
During the long-term operation of the 3D intelligent measuring instrument, both the heat generated by the device itself and changes in environmental temperature will affect the measurement accuracy. The traditional metal material measurement platform has a relatively high coefficient of thermal expansion and is prone to dimensional changes under temperature fluctuations, resulting in the offset of the measurement reference. The coefficient of thermal expansion of the ZHHIMG granite platform is only (4-8) ×10⁻⁶/℃, which is less than one-third of that of metal materials. In the semiconductor chip manufacturing workshop, the ambient temperature may fluctuate by about 5℃ due to the start and stop of air conditioning. At this time, the metal platform may undergo a deformation of 60μm, while the deformation of the ZHHIMG granite platform is only 20-40 μm. This extremely small dimensional change can ensure the stability of the coordinate system of the 3D intelligent measuring instrument, keeping the measuring probe always in its precise initial position and avoiding measurement errors caused by thermal deformation. It is particularly suitable for the measurement of chip structures with strict requirements for nanoscale dimensional accuracy.
High rigidity and uniform structure, resistant to external force interference
During the 3D intelligent measurement process, when the measuring probe comes into contact with the object being measured, a certain force will be generated. At the same time, the mechanical movement of the equipment will also cause vibrations. The internal mineral crystal structure of the ZHHIMG granite platform is dense and uniform, with a hardness as high as 6-7 on the Mohs scale and a compressive strength exceeding 120MPa, enabling it to easily withstand various external forces during the measurement process. Even under frequent probe movements, rapid scanning and other operations, the granite platform will not undergo elastic or plastic deformation. Its uniform structural characteristics can also effectively suppress the vibration transmission caused by external forces and prevent vibration from interfering with the precise positioning of the measurement probe. For instance, in the measurement of complex curved surfaces of aerospace components, the ZHHIMG granite platform can still maintain stability in the face of uneven forces caused by irregular shapes, ensuring the reliability of the measurement data.
Outstanding damping performance eliminates the influence of vibration
Vibration is one of the important factors affecting the accuracy of 3D intelligent measuring instruments. The operation of other equipment in the workshop and the movement of personnel may all generate vibrations. If these vibrations are transmitted to the measuring equipment, they will cause the measuring probe to shake, resulting in data acquisition deviations. The ZHHIMG granite platform has a natural high damping characteristic. The mineral particles and tiny pores inside can rapidly convert vibration energy into thermal energy and dissipate it. When external vibrations are transmitted to the platform, it can attenuate over 90% of the vibration energy within one second. Compared with the 3 to 5 seconds of a metal platform, this significantly shortens the time for the equipment to return to stability. In the 3D contour measurement of precision molds, this excellent damping performance can ensure the smooth operation of the measurement probe, obtain continuous and accurate point cloud data, thereby improving the measurement efficiency and data quality.
Non-magnetic and chemically stable, ensuring a pure measurement environment
Some 3D intelligent measuring instruments use inductive, magnetic grid and other sensors that are sensitive to magnetic fields. The magnetism of the metal platform can interfere with the normal operation of the sensors. The ZHHIMG granite platform is a non-metallic material, non-magnetic and non-conductive, and will not cause any electromagnetic interference to the sensor, creating a pure electromagnetic environment for the measuring equipment. In addition, granite has stable chemical properties and is resistant to acid and alkali corrosion. Even in complex environments such as humidity and corrosive gases, it can still maintain stable performance and will not be affected by surface corrosion or oxidation in terms of measurement accuracy, thus extending the service life of 3D intelligent measuring instruments.
After many enterprises replaced the metal platforms of 3D intelligent measuring instruments with ZHHIMG granite platforms, the measurement accuracy was significantly improved. After a certain precision machinery manufacturing enterprise introduced the 3D intelligent measuring instrument equipped with the ZHHIMG granite platform, the measurement error of complex gears was reduced from the original ±15μm to within ±5μm, and the reliability of product quality inspection was significantly enhanced.
The ZHHIMG granite platform, with its inherent advantages such as an ultra-low coefficient of thermal expansion, high rigidity, excellent damping performance, non-magnetism and chemical stability, provides a stable and reliable measurement foundation for 3D intelligent measuring instruments, helping various industries achieve high-precision and high-efficiency quality inspection, and has become an important force promoting the development of intelligent manufacturing.
