Precision Granite V-Blocks – Engineered for Ultra-Precise Metrology & Industrial Alignment
In ultra-precision manufacturing, even microns matter. That’s why leading metrology labs, semiconductor fabs, and aerospace manufacturers trust ZHHIMG® granite V-blocks — not just as tools, but as foundational elements of their quality control ecosystem. Crafted from our proprietary ZHHIMG® black granite (density ≈3100 kg/m³), these V-blocks outperform conventional marble or steel alternatives in thermal stability, wear resistance, and long-term dimensional integrity. Unlike mass-produced imitations, each pair is hand-lapped by master craftsmen with over 30 years of experience — professionals our clients call “walking electronic levels” for their ability to feel micron-level deviations by touch alone.

- • Unmatched Material Integrity: Our ZHHIMG® black granite is denser and more stable than European or domestic marble — resisting warping, moisture absorption, and thermal drift.
- • Hand-Lapped Precision: Each V-groove is finished by artisans who can detect sub-micron errors by feel — ensuring repeatability no machine can replicate.
- • Certified Accuracy: Every unit comes with calibration certificates traceable to national standards, meeting DIN 876, ASME B89.3.7, and JIS B 7511 requirements.
- • Thermal & Vibration Damping: Ideal for use in constant temperature and humidity environments — our granite absorbs vibrations better than steel, critical for nanometer-level measurements.
- • Global Compliance: Trusted by GE, Samsung, Bosch, and national metrology institutes — we meet the strictest international standards.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Q: Can I order custom sizes or angles?
A: Absolutely. We specialize in non-standard customization — whether you need 60°, 120°, or special mounting features, our engineers will design and manufacture to your exact specs.
Q: How do I maintain the V-blocks?
A: Clean with lint-free cloth and isopropyl alcohol. Store in a dry, temperature-controlled environment. Avoid dropping or impacting — granite is hard but brittle.
Q: Do you provide calibration certificates?
A: Yes. Every shipment includes full calibration reports from Jinan or Shandong Metrology Institutes, traceable to NIM (China) or equivalent national bodies.
Q: What’s the lead time for standard vs. custom orders?
A: Standard sizes ship within 7–10 days. Custom orders typically take 15–25 days depending on complexity.
