\ud83c\udfaf Core Advantages<\/p>\n
The advantages of granite mainly stem from its natural and stable physical properties:<\/p>\n
\u00b7 Longterm precision and stability
\n\u00b7 Characteristics: After billions of years of natural aging, the internal stress of the rock has been eliminated, and it hardly deforms. The of thermal expansion is extremely small, and it is insensitive to temperature changes.
\n\u00b7 Advantages brought: It can maintain a working precision of microns or even higher for a time (for example, the flatness can reach 2 microns), making it an ideal reference measuring surface and equipment base.
\n\u00b7 Excellent physical and chemical properties
\nCharacteristics: High hardness, wear resistance; non-conductive, non-magnetic; resistant to acid and alkali corrosion.
\n\u00b7 Advantages brought: Long service life suitable for electromagnetic sensitive environments; no need for oiling to prevent rust, simple maintenance.
\n\u00b7 Excellent damping and shock-absorbing properties
\n\u00b7 Characteristics: The internal structure can effectively absorb and attenuate vibrations.
\n\u00b7 Advantages brought: Significantly reduce the vibration of the equipment itself and external interference, and improve the stability of precisionining and measurement.<\/p>\n
\ud83d\udee0\ufe0f Main Application Fields<\/p>\n
Based on the above advantages, granite components play a central role in many high-precision and cutting-edge fields:
\n\u00b7 Precision measuring instruments
\n\u00b7 Typical equipment: Workbench, guide rail, and beam of the three-coordinate measuring machine; various granite plates, straightedges, and gauges, etc., as reference measuring tools.
\n\u00b7 Role: As a geometric reference for measurement, its stability directly determines the measurement accuracy of the instrument.
\n\u00b7-end manufacturing and testing equipment
\n\u00b7 Typical equipment: Base and workbench of high-precision CNC machining centers, laser equipment, and optical equipment; frame of optical inspection equipment.
\n\u00b7 Role: Provide a super stable and vibration-resistant “foundation” for the equipment, ensuring that the machining and testing processes are not.
\n\u00b7 Semiconductor and electronic industries
\n\u00b7 Typical equipment: Wafer air-floating platform, precision positioning platform, PCB drilling machine body.
\nRole: In a cleanroom environment, its dust-free, low thermal expansion, and highly stable characteristics are key to ensuring nanometer-level process precision.
\n\u00b7 Other precision
\n\u00b7 Typical equipment: Precision motion truss systems that require ultra-high repeat positioning accuracy (such as below 6 microns).
\n\u00b7 Role: Used high-rigidity and high-damping mechanical structural components to improve the dynamic performance of the system.<\/p>","protected":false},"excerpt":{"rendered":"
