Precision Granite Base

✅ Superior Material Quality

Our granite is sourced exclusively from high-grade natural stone, meticulously selected for uniformity, low porosity, and minimal internal stress. Unlike many competitors who use cheaper materials like marble or composite stones, ZHHIMG uses only genuine black granite — the gold standard in metrology and ultra-precision machinery.

✅ Ultra-Precise Machining & Finishing

Manufactured using Taiwan-made Nantec grinding machines (each over 500,000 USD) and processed in our 10,000m² temperature-controlled, vibration-isolated workshop, every surface achieves sub-micron flatness. Our skilled craftsmen — with over 30 years of hand-finishing experience — can detect changes down to micro-levels by touch alone, earning them the nickname "walking electronic levels."

✅ Exceptional Dimensional Stability

With a coefficient of thermal expansion as low as 6.5×10⁻⁶ /°C, this granite base maintains its geometry under varying environmental conditions. Whether in cleanrooms, semiconductor fabs, or outdoor testing environments, it resists warping and thermal drift — ensuring consistent performance over time.

✅ Customizable Design & Integration

Available in various sizes, thicknesses, and mounting configurations, this base supports integration into:

•   CNC machine beds
•   Coordinate Measuring Machines (CMMs)
•   Laser alignment platforms
•   Semiconductor handling stages
•   Optical inspection tables
•   Industrial CT scanners

The integrated T-slots and mounting holes allow quick tooling setup, while the precise edge alignment ensures perfect fitment with linear guides, air bearings, or motorized drives.
