How to Repair Scratches on Granite Machine Tool Bed Surfaces
As the precision benchmark of the whole machine, the integrity of the working surface of a granite machine tool bed directly determines the positioning and motion accuracy of the equipment during long-term operation. Scratches may form on the granite bed surface from tool collisions, friction by ...Read more -
Granite Assembly Components Feature Strong Vibration Damping, Ideal for Precision Inspection Equipment
The success of micron-level inspection often does not depend on the measurement algorithm of the equipment itself, but on whether the reference platform can isolate disturbances induced by environmental vibration. Inside factory workshops, operation of conveyor belts, start-stop of surrounding ma...Read more -
Granite Assembly Components: Integrated Lapping Guarantees Equipment Assembly Accuracy
Many assembly errors of ultra-precision equipment do not stem from component assembly procedures, but from flatness and straightness deviations of the reference body itself. When a base is assembled from multiple segments, if each individual part adopts an independent machining reference, cumulat...Read more -
What Inspection Equipment Are Granite Assembly Components Suitable For?
The core demand of ultra-precision inspection equipment is to maintain a stable datum throughout long hours of continuous measurement. The credibility of inspection data largely depends on the physical stability of the equipment’s base and supporting structure. Metal substrates are prone to...Read more -
Can Granite Assembly Components Be Customized According to Drawings?
In the ultra-precision equipment industry, standard granite platforms and measuring tools can only meet a small portion of conventional equipment demands. A large number of projects for semiconductors, laser inspection and precision motion platforms involve unique structural layouts, installation...Read more -
The Human Touch Behind Nanometer Precision: ZHHIMG’s Master Craftsmen
Every precision shop has the same quiet problem. The grinding machine can bring a granite surface within a few microns of flat. Then it stops. The last stretch — the part that decides whether a surface plate is a tool or a doorstop — cannot be cut by a spinning wheel. It is finished by hand. That...Read more -
Installation Details of Granite Assembly Components
As the core fundamental components for ultra-precision industry, ZHHIMG granite assembly components feature high density, superior stability and low deformation. They serve as the base and supporting structure for high-end equipment including semiconductor machinery, precision measuring instrumen...Read more -
Why Semiconductor Equipment Manufacturers Choose ZHHIMG Granite Components
Ask any semiconductor equipment engineer what keeps them awake, and the answer is rarely the motion system or the optics. It is the floor the machine stands on. A wafer stage that holds 2 nanometres of position on paper still needs a base that will not drift, ring, or warm up under it. That base ...Read more -
If You Can’t Measure It, You Can’t Make It: ZHHIMG’s Metrology Philosophy
There is an old line on the shop floor: if you can’t measure it, you can’t make it. It sounds simple. It is not. Every precision machine is only as good as the reference it is measured against, and every tolerance is only as real as the instrument that confirms it. This is the part of...Read more -
Why ZHHIMG Black Granite Outperforms Marble for Precision Equipment Bases
Engineers ask us the same question at least once a month. “We need a base for a measuring machine. Your black granite looks like the marble slab we can buy locally, and that one is cheaper. Why should we pay more?” It is a fair question. From a distance, marble and black granite are b...Read more -
From a Jinan Factory to GE, Samsung and Apple: How ZHHIMG Became the Choice of Global Precision Customers
Walk into a precision workshop in the industrial belt along the Yellow River in Jinan, Shandong, and you will see something unusual: slabs of black granite so large they are moved by overhead cranes, ground and lapped by hand to flatness measured in microns. That workshop is where ZHHIMG — Zhongh...Read more -
Can Granite Bases for Height Gauges Be Drilled to Install Fastening Accessories?
Many metrology engineers face a common practical requirement when building height gauge measurement stations: drilling holes on granite bases to mount positioning pins, pressure plates, limit blocks, leveling feet and other fastening accessories. A lot of people worry that granite is brittle. Wil...Read more
