Industrial CT non-destructive testing puts forward extremely stringent requirements for the stability of bearing platforms. Minor structural deformation, subtle external vibration or temperature-induced displacement will create scanning artifacts, distort 3D reconstruction results and cause erroneous judgments on tiny internal flaws of tested workpieces. Against this industry challenge, ZHHIMG develops dedicated stable granite platforms, delivering trustworthy structural foundations for global industrial CT equipment manufacturers.
The granite platforms are fabricated from premium natural black granite featuring a density of approximately 3100kg/m³. This material boasts outstanding inherent vibration damping performance and minimal thermal deformation, outperforming ordinary marble widely used by many low-end suppliers. ZHHIMG always adheres to the principle of “No cheating, No concealment, No misleading” and firmly refuses to substitute granite with cheap marble, eliminating hidden precision risks for CT inspection equipment in long-term operation.
All finishing and precision inspection procedures are carried out inside our 10,000 ㎡ constant temperature and humidity workshop. The workshop floor is poured with ultra-hard concrete over 1000mm thick, enclosed by anti-vibration trenches with silent travelling cranes deployed inside. Such a well-built processing environment effectively isolates external vibration interference, laying a solid foundation for the long-term geometric stability of large granite platforms. Our senior polishing specialists with over 30 years of hand lapping experience conduct fine surface processing. Every technician receives systematic training on international metrology standards covering DIN, ASME, JIS, GB and other specifications, ensuring the flatness and positioning benchmark of each platform meet the assembly demands of industrial CT motion systems.
Supported by four Taiwan Nantou ultra-large grinding machines, each worth more than USD 500,000, ZHHIMG can customize granite platforms in diversified sizes, with the maximum processing length reaching 20 meters. Comprehensive quality verification is implemented throughout production. We deploy world-class inspection instruments including Mahr dial gauges, Mitutoyo precision measuring tools, WYLER electronic levels and Renishaw laser interferometers. All testing equipment holds calibration certificates issued by official metrology institutions, making measurement data traceable to national measurement standards. 
As the only manufacturer in the industry simultaneously possessing ISO9001, ISO45001, ISO14001 and CE certifications, ZHHIMG has obtained more than 20 international trademarks and patents registered in the EU, the United States, Southeast Asia and other regions. We maintain long-term technical exchanges with prestigious universities and metrology institutes across the globe, continuously optimizing the structural design of granite platforms for non-destructive testing scenarios.
Mounted under rotary fixtures and scanning modules of industrial CT devices, our granite platforms maintain stable precision during round-the-clock continuous detection, greatly lowering the frequency of equipment recalibration. The products have gained recognition from numerous equipment suppliers serving automotive, aerospace, electronics and new energy sectors. Guided by the quality policy “The precision business can’t be too demanding”, ZHHIMG will keep optimizing ultra-stable granite structural components and provide reliable customized solutions for the global non-destructive testing industry.
