Key Lapping and Processing Techniques for Flatness of Granite Inspection Plates
As the most fundamental reference benchmark in industrial precision inspection, the flatness of granite inspection plates directly determines the credibility of dimensional measurement, part calibration and equipment error detection results. Unlike ordinary mechanical processing, flatness lappin...Read more -
Zero-Expansion Granite Square Ruler: The Ultimate Datum Tool for Verticality Detection
Verticality accuracy is one of the most fundamental and critical indicators in ultra-precision machining, equipment assembly and dimensional inspection. The vertical datum error of measuring tools will be directly amplified in equipment calibration and workpiece testing, leading to batch process...Read more -
Influence of Granite Gantry Component Surface Treatment Technology on Overall Equipment Performance
Core Correlation Between Granite Surface Treatment and Whole Machine Performance The surface treatment of precision granite gantries is not a simple cosmetic process, but a key precision engineering link that determines equipment core performance. First, surface flatness directly determines ass...Read more -
Low-Stress Granite Gantry Components: Effectively Eliminate Long-Term Service Deformation
Long-term precision retention is the core pain point of ultra-precision equipment operation. For high-end fields such as semiconductor manufacturing, femtosecond laser processing, optical detection and new energy precision testing, tiny structural deformation of gantry components caused by resid...Read more -
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 -

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
