Precision Granite Inspection Plate

1️⃣ Superior Dimensional Stability

Granite does not deform under internal stress like cast iron. No rust, no corrosion, no magnetic interference.

2️⃣ Precision Multi-Bore Configuration

The four-hole layout allows repeatable fixture mounting and modular assembly integration, ideal for:

•   CMM fixture bases

•   Optical alignment platforms

•   Automated inspection systems

•   Semiconductor component testing

3️⃣ High Density Black Granite (Not Marble)

Many low-cost suppliers substitute marble to reduce cost. Marble lacks hardness and long-term stability.

ZHHIMG® exclusively uses engineered black granite with higher density and superior physical performance compared to many European and American granite sources.

4️⃣ Exceptional Vibration Damping

Granite naturally absorbs micro-vibrations, making it ideal for:

•   Laser systems

•   Optical measurement

•   Battery testing systems

•   High-speed linear motor platforms

5️⃣ Micron-Level Flatness Control

Hand-lapped by master technicians with over 30 years of experience, achieving consistent micro-level removal accuracy.

Customers often describe our grinding specialists as “walking electronic levels.”
