What Key Parameters Should Be Marked on Drawings for Custom Precision Granite Components?
When customizing granite bases, beams and substrates, many equipment manufacturers only mark length, width, thickness and hole positions on drawings. They ignore the unique reference system, machining limits and metrology acceptance conditions of granite materials. Incomplete drawing information ...Read more -
What Core Challenges Can Be Solved by Adopting Granite Components for Automated Equipment?
During the iterative upgrading of automated inspection and motion platforms, manufacturers keep pursuing faster scanning speed, higher repeat positioning accuracy and stable long-term operation. Many equipment manufacturers have tried various structural substrates such as aluminum alloy, cast iro...Read more -
What Special Processing Procedures Do Precision Granite Components Undergo?
Many people assume that the production of precision granite components only involves simple stone cutting followed by surface polishing. However, to achieve micron or even nanometer-level accuracy, granite bases, beams, square boxes and substrates used in high-end equipment for semiconductors, op...Read more -
Mineral Casting vs. Cast Iron Machine Beds: Vibration Damping, Thermal Stability, and Design Considerations
Three different materials that are often confused Before any comparison, the terms have to be separated, because they are routinely mixed up in enquiries and even in supplier literature: Natural granite: a quarried stone, sawn and lapped. Its structure is what the quarry produced — no binder, no...Read more -
Granite vs. Ceramic vs. Steel Straight Edges: Which Precision Reference Tool Should You Choose?
Straight edges, squares, parallels and surface plates: four tools, four jobs Before comparing materials, it is worth separating the tools, because they are often confused in inquiries: A straight edge is a reference line. You lay it on a surface or hold it against a machine way to check straight...Read more -
Granite Air Bearings Explained: Working Principles, Advantages, and Applications in Ultra-Precision Motion Systems
What an air bearing actually is An air bearing is a fluid-film bearing in which the working fluid is compressed air. Instead of balls, rollers or an oil film, a thin layer of pressurised gas — the air film — separates the moving and stationary parts, so the two surfaces never touch during normal ...Read more -
Precision Granite Machine Bases for Semiconductor Equipment: Design, Accuracy, and Custom Manufacturing
Why semiconductor equipment is built on granite Semiconductor manufacturing equipment lives or dies by geometric stability. Lithography stages, wafer inspection systems, metrology tools and laser micromachining platforms all position optics, sensors and workpieces with tolerances measured in micr...Read more -
Granite Surface Plate: How to Choose the Right Grade, Size, and Flatness for Precision Measurement
What a granite surface plate is for A granite surface plate is a reference plane: a large, extremely flat piece of stone used as the common datum against which other things are measured or assembled. In practice it serves three jobs. In dimensional inspection it is the base on which height gauges...Read more -
Custom Manufacturing of High-precision Reference Granite Inspection Bases
In the field of precision metrology, standard bases can only cover general inspection equipment. A large number of cutting-edge inspection projects require exclusive reference carriers fully matching equipment principles, travel ranges and metrology grades. When purchasing custom bases, many equi...Read more -
Custom Grooving, Drilling & Precision Machining to Fabricate Granite Bases for Non-Standard Inspection Equipment
Standard inspection equipment comes with mature base solutions. However, non-standard inspection devices often feature unique motion module layouts, sensor mounting points, wiring requirements and load structures. At the R&D stage of non-standard equipment, many developers tend to prioritize ...Read more -
High Flatness Granite Inspection Base Provides Reliable Reference Surface for Sensors and Probes
The measurement results of modern precision inspection systems are essentially displacement calculations of probes and sensors relative to a fixed geometric origin. Many people place all precision pressure on sensors and optical probes themselves, continuously improving the sampling rate and reso...Read more -
What are the easily overlooked key points in the installation and leveling of granite inspection bases?
As the geometric reference origin of the whole inspection system, ultra-precision granite inspection bases have completed nanometer-level surface grinding and full metrology verification before leaving the factory. Many on-site commissioning personnel simplify installation and leveling as “...Read more
