Ultra-Precision Granite Surface Plates & Platforms for Global Industry Leaders
Founded in Jinan, China, ZHHIMG® has spent decades perfecting the art and science of precision granite components. Our journey began with a simple observation: the world's most demanding industries needed granite platforms that exceeded existing standards—and no one was delivering that consistently.
Today, we operate the most advanced granite processing facility in Asia. Four Taiwanese Nantex ultra-large grinding machines—each valued at over $500,000—stand ready to mill surfaces up to 6,000mm in length with micron-level precision. Our 10,000m² climate-controlled workshop, designed with specialized vibration isolation channels, ensures that thermal expansion and ambient vibrations never compromise your tolerances.
When you choose ZHHIMG®, you're not just buying a granite plate—you're investing in 20+ years of materials science expertise, 2M+ in German and Swiss metrology equipment for quality verification, and a supply chain partnership with industry titans like GE, Samsung, Apple, and Oracle who trust our components in their most critical applications.

1. The granite is after a long-term natural aging, the organizational structure is uniform, the expansion cofficient is small, the internal stress completely disappeared.
2. Not afraid of acid and alkali corrosion, will not rust; do not need oiling, easy to maintain, long service life.
3. Not limited by the constant temperature conditions, and can maintain the high precision at room temperature.
No be magnetized, and can move smoothly while measuring, no tight feeling, free of the affect of moisture, good flatness.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)
1. Documents together with products: Inspection reports + Calibration reports(measuring devices) + Quality Certificate + Invoice + Packing List + Contract + Bill of Lading(or AWB).
2. Special Export Plywood Case: Export fumigation-free wooden box.

A:How do I determine the right flatness tolerance for my application?
Q:Flatness tolerance selection depends on your measuring or machining requirements. For laboratory-grade coordinate measuring machines, Grade 00 tolerances (≤2μm per meter) are typically specified. Production inspection equipment usually requires Grade 0 (≤5μm per meter), while general machining fixtures can utilize Grade 1 tolerances (≤12μm per meter). Our applications engineering team can recommend optimal specifications based on your equipment type, operating environment, and budget constraints.
A:What are the key advantages of granite over steel or cast iron bases?
Q:Granite offers several distinct advantages: First, superior vibration dampening—the material naturally absorbs harmonic frequencies that steel amplifies. Second, thermal stability—granite's low thermal expansion coefficient (5.5×10⁻⁶/°C) means minimal dimensional drift during temperature variations. Third, corrosion resistance—granite will never rust or corrode, even in humid environments. Fourth, wear resistance—the Mohs 6.5-7.0 hardness maintains surface integrity over decades of use. Fifth, non-magnetic properties—critical for semiconductor and metrology applications where magnetic interference is unacceptable.
A:Can ZHHIMG manufacture custom configurations with specific hole patterns?
Q:Absolutely. We specialize in application-specific custom manufacturing. Our CNC-controlled grinding and drilling systems can produce virtually any geometric configuration—including through-holes, blind holes, T-slots, mounting pads, and recessed features—to your exact specifications. Standard lead time for custom configurations is 3-6 weeks depending on complexity and current production scheduling. We also offer rapid prototyping services for unique requirements.
A:How is flatness verified and certified for export shipments?
Q:Every precision granite platform undergoes comprehensive metrology verification before shipment. Our calibration chain includes German Mahr electronic comparators (0.5μm resolution), Swiss WYLER electronic levels for flatness mapping, and UK Renishaw laser interferometers for dimensional traceability to international standards. Each shipment includes a detailed inspection report with actual measurement data, environmental conditions during testing, and calibration certificates traceable to national standards.
A:What packaging and logistics arrangements are available for international delivery?
Q:We utilize specialized industrial crating with foam cushioning, moisture barriers, and reinforced timber framing designed for heavy machinery transport. All shipments are marine-grade packaged to withstand containerized ocean freight conditions. We coordinate with major freight forwarders for door-to-door delivery worldwide, handling customs documentation, certifications of origin, and all regulatory compliance paperwork. For large-scale orders, we offer consolidated container loading to optimize shipping costs.
