How to Carry Out Post-operation Protection and Maintenance for Black Granite Mechanical Beams
1. Standardize Daily Operation to Avoid Artificial and Mechanical Hard Damage Black granite mechanical beams possess high hardness and rigidity but feature natural brittleness with limited resistance to severe impact and hard collision. Most precision deviations in long-term service are not caus...Read more -
Comparative Analysis of Performance Differences Between Black Granite Mechanical Beams and Carbon Fiber Beams
In ultra‑precision equipment, mechanical beams serve as the load‑bearing skeleton and directly determine the machine’s repeat‑positioning accuracy and long‑term operational stability. Black granite and carbon‑fiber composite materials are two widely‑adopted beam materials for high‑end equipment....Read more -
Why Black Granite Mechanical Beams Are Widely Adopted in Semiconductor Equipment
As the semiconductor industry advances into the era of nanometer-level precision manufacturing, core processes such as photolithography, wafer inspection, precision packaging, and laser micro-processing impose extremely stringent requirements on the stability, precision consistency, and envir...Read more -
Technical Requirements for Granite Tables Used in AOI Optical Inspection Equipment
1. Base‑material Physical Properties: High Rigidity, Low Expansion and High Damping to Suppress Vibration Interference During high‑speed scanning of AOI equipment, frequent start‑stop of linear motors continuously generates vibration. Granite tables must attenuate vibration rapidly by material...Read more -
Influence of Handling and Storage Methods on Precision Degradation of Finished Granite Tables
1. Damages to Precision Induced by Non‑standard Handling Granite tables belong to heavy‑load precision components. Lifting, relocation, loading and unloading represent the highest‑risk procedures.

Influence of Granite Table Surface Protection Treatment on Long-Term Service Precision
It is well known that the core selection criteria for granite tables used in precision industries are high density, superior stability and low deformation. ZHHIMG strictly selects high-quality black granite base materials with a high density of up to 3100kg/m³, whose physical properties are far ...Read more -
How to Select the Right Gauge Block for High-Precision Calibration
Gauge blocks (often called Jo blocks) serve as the primary physical standard for dimensional metrology worldwide. Every micrometer calibration, height gauge zeroing, and coordinate measuring machine (CMM) axis audit traces its dimensional lineage back to a wringing stack of gauge blocks verified ...Read more -
Precision Casting vs Precision Machining: Which Process Is Right for Your Metal Component?
Choosing between precision casting and precision CNC machining dictates a metal component’s unit cost, structural integrity, lead time, and achievable dimensional tolerances. Engineers and procurement managers often face a common dilemma: cast complex geometry near net shape to reduce mater...Read more -
What Is a Granite Dial Base and Where Is It Used?
In high-precision manufacturing, capturing accurate height, thickness, concentricity, or runout measurements requires more than just a high-resolution measuring instrument. Even the finest dial indicator or digital probe yields inconsistent readings if mounted on an unstable, flexible, or thermal...Read more -
5 Signs Your CMM Granite Base Needs Resurfacing
Coordinate Measuring Machines (CMMs) serve as the final arbiter of dimension in modern manufacturing. Whether measuring aerospace turbine blades or high-precision semiconductor stage components, a CMM relies entirely on the structural integrity and flatness of its granite base. While natural gran...Read more -
Granite vs Cast Iron Surface Plate: Which One Fits Your Precision Measurement Needs?
In precision manufacturing, every accurate height, parallelism, or flatness measurement relies on an unyielding baseline: the surface plate. For decades, metrology labs and machine shops faced a straightforward choice between cast iron and natural granite. While modern sub-micron applications fav...Read more
