How to Inspect, Calibrate and Maintain a Granite Surface Plate
A granite surface plate is the reference everything else in your lab or workshop is measured against — which means it is also the item whose condition you can least afford to guess. Plates drift slowly and invisibly: wear under handling, foundation settlement, temperature events, even the gradua...Read more -
Granite Surface Plates Have No Internal Stress and Maintain Accuracy for a Long Period After Machining
Many professionals in precision manufacturing face a tough problem: newly accepted reference platforms gradually lose flatness and drift in accuracy after being put into service, requiring re-grinding back at the factory. Such accuracy degradation rarely results from daily wear. It arises mainly ...Read more -
Classified Inspection for Factory-Delivered Granite Surface Plates with Flatness Test Certificates
Many customers purchasing precision metrology tools tend to fall into a misunderstanding. They only focus on the appearance and nominal accuracy of granite surface plates while ignoring the authenticity of factory inspection, classification criteria and data traceability. Some stone gauge supplie...Read more -
Natural Granite Surface Plates Are Hardly Magnetized, Freeing Magnetic Workpiece Measurement From Interference
1. Hidden Industry Pain Point: Magnetization Errors Restrict High-End Precision Inspection Many core workpieces in new energy, semiconductors, precision laser systems and intelligent sensing sectors carry magnetism or are highly sensitive to magnetic fields. Examples include magnetic hardware par...Read more -
Difference in Performance of Granite Surface Plates Between Constant-Temperature Laboratories and Ordinary Workshops
1. Core Environmental Variables: The Fundamental Dividing Line for Precision Stability The golden rule of ultra-precision measurement is: a stable environment guarantees an unchanged reference. Even granite, with superior physical properties, cannot fully avoid micro-deformation triggered by exte...Read more -
Granite Air Bearings: How They Work and Why Granite Is the Ideal Guideway Material
Air bearings achieve what no contact bearing can: motion without wear, without stick-slip and without lubrication, at sub-micron straightness levels. But an air bearing is only as good as the surface it floats on. This article explains the physics of air films, why fine-grained natural granite i...Read more -
Optical Bench Bases Support Non-Standard Openings and Slots to Perfectly Adapt to Complete Optical Systems
I. Breaking Traditional Constraints: The Evolution from Single Flat Plates to Multi-Dimensional Functional Integration Traditional standardized stone or metal plates often only provide simple flat support, appearing inadequate when facing intricate optical matrices. Liberation of Spatial Layout...Read more -
Constructing Optical Defense Lines with Nanoscale Skeletons: Deconstructing the Dynamic Damping Art of Granite Bases
The Natural Damping of Crystalline Network Structures Although metallic materials possess good machining performance, when facing complex dynamic disturbances, the attenuation speed of their internal elastic waves is often unsatisfactory, making them prone to continuous resonance tails. In contra...Read more -
How to Choose a Granite Machine Base for CMM, Semiconductor and Laser Equipment
For coordinate measuring machines, semiconductor metrology tools and laser systems, the granite base is not a commodity purchase — it is the foundation the entire error budget rests on. Two suppliers can quote the “same” base and deliver very different machines, because the differenc...Read more -
What Material is Suitable for Optical Bench Bases in Non-Magnetic Optical Inspection Scenarios?
In cutting-edge scenarios such as modern non-magnetic optical inspection, high-sensitivity magneto-optical Kerr effect testing, electron spin resonance analysis, and specific semiconductor wafer non-destructive probing, any weak magnetic field interference can cause sensor drift or distortion in ...Read more -
Practical Key Points for Installing Vibration-Damping Supports and Leveling Optical Bench Bases
In ultra-precision optical, laser processing, and high-resolution inspection systems, an optical bench base not only requires superior intrinsic material properties, but also relies heavily on rigorous on-site installation of vibration-damping supports and precision leveling processes. Serving as...Read more -
Material Selection for Optical Bench Bases: Why “Physical Properties and Micro-Stability” Are the Core Key to the Ultra-Precision Industry
In modern ultra-precision optics, laser processing (such as femtosecond and picosecond laser systems), optical inspection (AOI), and semiconductor equipment, optical bench bases play a crucial role akin to the “human skeleton and foundation.” An excellent optical bench base must not o...Read more
