Product Introduction

The Foundation Behind Ultra-Precision Manufacturing
In ultra-precision industries, every micron matters.
A machine can only achieve its designed accuracy when its structural foundation remains stable over time. The ZHHIMG® Precision Granite Component is engineered as a high-performance mechanical foundation for advanced equipment where rigidity, thermal stability, vibration control, and dimensional accuracy are critical.
Unlike ordinary structural materials, precision granite provides natural advantages for high-end applications. Its dense crystalline structure delivers excellent vibration damping and long-term geometric stability, making it an ideal choice for semiconductor equipment, coordinate measuring machines (CMM), optical inspection systems, laser processing equipment, and precision automation platforms.
Manufactured from ZHHIMG® high-density black granite with a density of approximately 3100 kg/m³, these custom granite components are precision machined and measured under controlled environmental conditions to ensure reliable performance in demanding industrial environments.

Core Advantages

1. High-Density Black Granite for Superior Stability

Not all granite materials provide the same performance.

ZHHIMG® selects high-density black granite with excellent mechanical stability, helping reduce:

• thermal deformation
• structural movement
• vibration influence
• long-term accuracy drift

This makes it suitable for precision equipment operating continuously in demanding environments.

2. Excellent Vibration Damping Performance

Precision equipment is highly sensitive to vibration.

The natural damping characteristics of granite help absorb external vibration energy, improving:

• measurement repeatability
• positioning accuracy
• image inspection stability
• machining consistency

3. Custom Engineering According to Customer Drawings

Every precision system has different requirements.

ZHHIMG® provides customized granite components based on:

• CAD drawings
• STEP files
• equipment specifications
• tolerance requirements
• assembly interfaces

Available machining options include:

• precision holes
• embedded inserts
• mounting surfaces
• complex pockets
• customized structures

4. Professional Metrology-Based Quality Control

Precision cannot be manufactured without accurate measurement.

ZHHIMG® follows a measurement-driven manufacturing philosophy:

"If you cannot measure it, you cannot produce it."

Each component can be inspected using advanced measurement equipment including:

• Mahr precision indicators
• Mitutoyo measuring instruments
• WYLER electronic levels
• Renishaw laser interferometers

Inspection reports and calibration documents are available for customer verification.

Quality Control

We use various techniques during this process:

● Optical measurements with autocollimators

● Laser interferometers and laser trackers

● Electronic inclination levels (precision spirit levels)

Quality Control

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.
