Case Study: Supplying Ultra-Precision Components for Aerospace Inspection Systems
Aerospace inspection systems operate under some of the tightest tolerance requirements in industrial manufacturing. A single out-of-spec granite base, ceramic fixture plate, or mounting component can propagate error through an entire CMM or optical inspection line — resulting in scrapped parts, f...Read more -
How to Identify Stone Quality for Granite Gantry Components: Avoid Industry Shoddy Material Phenomena
As a benchmark enterprise in the ultra-precision stone industry, ZHHIMG has long been engaged in the R&D and production of ultra-precision components including granite, ceramic, metal and glass parts.

2026 Trends in Ultra-Precision Manufacturing: The Rise of Artificial Granite (Polymer Concrete)
For decades, natural granite has been the default choice for precision machine bases, CMM structures, and surface plates. Its low thermal expansion and excellent damping properties are well documented and trusted across the metrology industry. But as precision manufacturing pushes toward larger m...Read more -
Overcoming Thermal Expansion: Why Precision Glass and Zerodur are Critical for Optical Metrology
In optical metrology, the smallest thermal fluctuation can become the largest source of measurement uncertainty. A reference mirror, interferometer optic, or wavefront sensor mount that expands or contracts by even a fraction of a micron under normal ambient temperature swings can silently invali...Read more -
From Raw Stone to Micron Precision: The Manufacturing Process of Large-Scale Granite Gantry
For quality control engineers and metrology lab managers, few decisions carry as much long-term weight as the selection of a coordinate measuring machine (CMM) base or gantry structure. A gantry that drifts even a few microns under thermal load, vibration, or self-weight can quietly undermine an ...Read more -
Why Zero Porosity Black Granite is the Gold Standard for Semiconductor Equipment Components
Semiconductor equipment depends on mechanical stability that is often measured in microns—or, in critical stages, fractions of a micron. Wafer inspection systems, lithography subsystems, laser-processing machines, metrology platforms, precision motion stages, and optical assemblies can all lose r...Read more -
Why Do Metrology Laboratories Prefer Natural Granite Worktables?
As core authoritative venues for traceability of precision values, instrument calibration and accuracy testing, metrology laboratories undertake key tasks including industrial metrology calibration, scientific research data verification and product precision inspection. They impose extremely str...Read more -
Full Process Control Points of Precision Granite Worktables: From Raw Stone Selection to Finished Products
The nanometer-level accuracy, long-term stability and zero-decay performance of precision granite worktables cannot be achieved through a single processing procedure. They rely on a full-process standardized control system covering raw stone selection, blank material pretreatment, precision mach...Read more -
Corrosion-resistant and aging-resistant: ZHHIMG black granite serves as the core base material for precision equipment
Introduction: The Unseen Enemy of Precision In the pursuit of nanometer-level accuracy, engineers and quality managers often focus on the most visible components: the linear scales, the high-resolution probes, and the sophisticated control software. However, the ultimate limit of a precision mach...Read more -
