How the surface reference accuracy of granite inspection base maintains long-term stability
In scenarios such as semiconductor optical inspection, coordinate measuring machines and laser precision measurement, the granite inspection base serves as the geometric origin of the whole set of equipment. Many bases meet the flatness standard upon factory inspection, yet reference drift and sl...Read more -
Precision Maintenance Plan for Granite Measuring Surface Plates
ZHHIMG® granite measuring surface plates, made of dense mineral base material with stress relief aging and nano-precision lapping, serve as core reference carriers for precision metrology, optical inspection and CMM measurement. Maintenance in many enterprises only covers simple cleaning and anti...Read more -
Store Granite Surface Plates with Moisture Proof and Light Shielding to Prevent Efflorescence and Discoloration
Many metrology and visual inspection workshops only focus on collision protection when storing ZHHIMG® precision granite surface plates, ignoring hidden deterioration caused by humidity and light. Although granite undergoes stress relief aging and nano-level precision lapping, there are still tin...Read more -
What Protective Measures Should Be Taken for Granite Surface Plates During Idle Storage?
Many enterprises only focus on protecting precision granite surface plates during measurement operations, yet tend to overlook protection during idle storage. While plates sit seemingly stationary and unloaded in warehouses, hidden factors including temperature and humidity fluctuations, ground s...Read more -
How to Maintain Precision Granite Surface Plates to Extend Service Life?
ZHHIMG® precision granite surface plates serve as core reference gauges in metrology labs and optical inspection workshops, featuring nano-level lapped reference surfaces. Many users assume granite is hard and barely needs maintenance. In fact, its ultra-high flatness is achieved by fine lapping....Read more -
Precision Lapped Granite Bases for AOI: Flatness Meets the Requirements of High-End Vision Equipment
The core principle of high-end AOI visual inspection lies in establishing a reliable geometric reference. Image capture, coordinate positioning and dimension measurement all take the base surface as the primary reference. Any undulation deviation in flatness will trigger systematic errors in the ...Read more -
Is the Granite Base Reliable for Long-Time Continuous AOI Inspection?
As the core online quality inspection equipment for semiconductor and PCB production lines, AOI machines mostly operate 7×24 hours nonstop. During continuous operation, repeated start-stop cycles of motion modules, persistent heat generation, and superimposed minor environmental disturbances impo...Read more -
What Are the Advantages of Granite for Semiconductor AOI Equipment Bases?
For semiconductor production lines, the requirements for AOI optical inspection go far beyond simple appearance defect identification. In processes such as chip packaging and wafer inspection, AOI systems continuously capture micron and even sub-micron defects. As the carrier benchmark for the en...Read more -
How Does the Granite Base of AOI Inspection Machine Reduce the Vibration Error of the Whole Machine?
In the operation of AOI automatic optical inspection equipment, tiny vibration-induced errors are the most hidden factor affecting yield. High-speed movement modules starting and stopping, subtle ground disturbances transmitted from the workshop environment, even nanometer-level relative displace...Read more -
Why AOI Equipment Prefers Granite Base
In PCB, semiconductor and panel production lines, AOI automatic optical inspection equipment undertakes the task of identifying tiny defects. With high-speed optical imaging, it needs to capture micron and even sub-micron flaws. Any slight shake or deformation of the reference surface will cause ...Read more -
How Precision Granite Components Are Inspected: Flatness, Straightness, and Acceptance Reports
Inspection is where a granite component earns its certificate By the time a granite component reaches the inspection stage, most of the value has already been added: the stone was selected, cut, and machined. What inspection does is convert all of that work into evidence — measured values, record...Read more -
Granite Air-Bearing Guideways and Ceramic Air Bearings: What to Specify Before Ordering
First, define what you are actually buying Air-bearing precision motion projects often stall at the quotation stage for a simple reason: the buyer and the supplier are not quoting the same object. These are different deliverables, and they should not be mixed in one inquiry: Granite guideway com...Read more
