Where Lie the Machining Difficulties of Precision Granite Components with Special-shaped Grooves and Deep Holes?
Many people’s perception of granite measuring tools remains limited to simple flat reference plates and straight rulers. As high-end equipment such as semiconductor devices, optical inspection systems and linear motor platforms becomes more integrated, an increasing number of granite bases need p...Read more -
What Long-term Differences Will Be Caused by Different Aging Cycles of Precision Granite Components?
Within the supply chain of ultra-precision equipment, many purchasers focus on comparing flatness, dimensional tolerances and quotations of granite components, yet easily overlook a key variable that determines the service stability of products over years: the aging cycle before and after granite...Read more -
Hidden Precision Indicators to Be Controlled in the Finishing of Precision Granite Components
When sourcing precision granite components, many purchasers tend to first verify obvious geometric tolerances such as flatness and straightness, which can be shown directly on inspection reports. They assume products will stably serve ultra-precision equipment for semiconductors, laser inspection...Read more -

Granite Air Bearings vs. Ceramic Air Bearings: How to Choose for Ultra-Precision Motion Stages Choosing between a granite air bearing and a ceramic air bearing is a decision that shapes the whole motion architecture of an ultra-precision stage. Both materials produce the same physical effect — a ...Read more -
Black Granite vs. Marble for Precision Components: How to Spot the Difference Before You Buy
Black Granite vs. Marble for Precision Components: How to Spot the Difference Before You Buy When buyers search for black granite vs marble precision differences, they are usually trying to answer a much more practical question: is the material in front of me actually what the quotation promised?...Read more -
Granite vs. Mineral Casting vs. Steel Weldment: Choosing the Best Machine Base for Precision Equipment
Granite vs. Mineral Casting vs. Steel Weldment: Choosing the Best Machine Base for Precision Equipment Choosing a granite machine base over a mineral casting or a steel weldment is one of the most consequential decisions in precision equipment design, because the base sets the ceiling for everyth...Read more -
Granite Surface Plate Grades Explained: 00, 0, 1 and 2, and How to Choose the Right Size
Granite Surface Plate Grades Explained: 00, 0, 1 and 2, and How to Choose the Right Size Granite surface plate grades are the first thing a buyer should understand before requesting a quotation, because the grade decides the flatness tolerance, the price, and whether the plate can actually suppor...Read more -
Granite vs. Cast Iron Surface Plates: Which One Is Right for Your Inspection Lab?
Granite vs. Cast Iron Surface Plates: Which One Is Right for Your Inspection Lab? Choosing between a granite surface plate and a cast iron surface plate is one of the first decisions an inspection lab has to make, and it is usually made too quickly. Both materials are still in daily use across me...Read more -
Machining of High-Stability Granite Base for CMM Mainframe
The CMM mainframe base serves as the geometric origin of the whole measuring machine. All three-axis geometric accuracy and repeatable measurement performance of the equipment are built upon the base benchmark. Many processors only focus on flatness indicators while ignoring raw material selectio...Read more -
What Protection Treatments Are Required for Granite Measuring Machines in Environments with Dust and Cutting Fluid?
Conventional granite CMMs are mostly deployed in clean metrology rooms. However, many production lines require measurement stations close to machining areas, where equipment is continuously exposed to metal dust, cutting fluid splashes and oil mist. Many users assume granite itself is immune to w...Read more -
What Accuracy Losses Are Likely to Occur in Daily Use for Granite Coordinate Measuring Machines?
Many users choose granite CMMs under the assumption that accuracy will remain stable for a long time as long as the base material is reliable. However, granite is not an immutable benchmark. In day-to-day inspection operations, environmental disturbances, operating habits, surface contamination a...Read more -
How Much Can a Granite Main Body Improve the Repeatability of a Coordinate Measuring Machine?
Within the performance specification system of a Coordinate Measuring Machine (CMM), repeatability describes the data dispersion when measuring the same feature repeatedly, and serves as the core indicator to judge equipment reliability. Many equipment manufacturers focus on improving repeatabili...Read more
