How Granite Components Perform on High-Speed CNC Machines
In high-speed CNC machining, dynamic stability, sustained precision and adaptability to working conditions are the core factors determining the quality of ultra-precision finished parts. Traditional cast iron and ordinary metal structural components tend to suffer vibration offset, thermal deform...Read more -
Why Semiconductor and CMM Equipment Use Granite Bases
Ask a structural engineer why the CMM bridge in their lab and the wafer inspection stage across town are both built on granite, and you will usually get a short answer: “stiff and stable.” The real answer is a set of five material properties that no single engineering alternative deli...Read more -
Granite Surface Plate Grades Explained: How to Choose Between Grade 00, 0, 1 and 2
Walk into any metrology lab or quality department and you will find a granite surface plate – and underneath its serial number, a grade letter or pair of zeros that most buyers order by habit rather than by decision. Choosing the wrong grade usually means one of two failures: paying for lab...Read more -
Granite vs. Marble: How to Tell Real Precision Granite from Cheap Substitutes
If you are buying a precision granite component for the first time, here is an uncomfortable fact: the global stone market has a gray zone, and not every dark, polished, heavy block sold as “granite” is a true precision granite. Marble – cheaper, softer, more porous – is t...Read more -
Large Granite Base with Aging Treatment to Avoid Potential Deformation in Later Stage
Most precision failures of large granite bases do not stem from insufficient machining accuracy, but spontaneous deformation caused by the release of hidden residual stress afterwards. Many small and medium processing factories only focus on passing pre-delivery inspections while ignoring the inh...Read more -
Large Granite Base: Moisture-proof and Corrosion-resistant to Reduce Equipment Maintenance Pressure
Precision gantry platforms and optical inspection equipment are often placed in workshops or laboratories, where moisture, cutting fluid mist and volatile acid-base substances are common. Metal bases are vulnerable to environmental erosion. Cast iron bases gradually rust, and anti-corrosion coati...Read more -
Trusted by Fortune 500s & Global Metrology Institutes: ZHHIMG®’s International Footprint
When a semiconductor equipment maker in Korea, a CMM manufacturer in Germany and a research group at a national metrology institute all specify the same brand of precision granite, it is not an accident of marketing. It is the result of two decades spent answering one question: who can deliver ge...Read more -
Large Granite Base Resists Deformation and Maintains Precision under Long-term Heavy Load
After commissioning, large-travel precision inspection equipment and gantry motion platforms often need to carry modules, optical assemblies and fixtures continuously year-round. The deformation stability of the base directly determines the precision service life of the whole machine. Many metal ...Read more -
What Risks Should Be Noted During Transportation and Installation of Large Granite Bases?
Large granite bases feature heavy dead weight and brittle material properties. Their finished datum surfaces are ultra-precision ground. Many easily overlooked risks exist during transportation and on-site installation. Improper handling may lead to scratches on the reference surface, or invisibl...Read more -
What Are the Main Machining Difficulties of Large Granite Bases?
For large-travel inspection machines, gantry motion platforms and precision optical systems, large granite bases bear the full machine load and act as the foundational component determining long-term precision stability. Many customers simply assume large bases are scaled-up versions of small gra...Read more -
Granite Surface Plates with Embedded Threaded Inserts for Easy Equipment Assembly and Fixing
In precision automation platforms, optical inspection tooling and metrology laboratories, granite surface plates act as reference bases. They frequently require repeated installation and removal of modules, fixtures and sensors. Tapping threads directly into solid granite brings obvious drawbacks...Read more -
Granite Surface Plate with T-slots: Is It Difficult to Machine?
In precision metrology, automated inspection and precision tooling industries, granite surface plates with T-slots are essential reference components for workpiece positioning, fixture mounting and module assembly. Many buyers assume T-slot machining is a simple grooving process and less challeng...Read more
