How to Choose a Granite Machine Base for CMM, Semiconductor and Laser Equipment
For coordinate measuring machines, semiconductor metrology tools and laser systems, the granite base is not a commodity purchase — it is the foundation the entire error budget rests on. Two suppliers can quote the “same” base and deliver very different machines, because the differenc...Read more -
What Material is Suitable for Optical Bench Bases in Non-Magnetic Optical Inspection Scenarios?
In cutting-edge scenarios such as modern non-magnetic optical inspection, high-sensitivity magneto-optical Kerr effect testing, electron spin resonance analysis, and specific semiconductor wafer non-destructive probing, any weak magnetic field interference can cause sensor drift or distortion in ...Read more -
Practical Key Points for Installing Vibration-Damping Supports and Leveling Optical Bench Bases
In ultra-precision optical, laser processing, and high-resolution inspection systems, an optical bench base not only requires superior intrinsic material properties, but also relies heavily on rigorous on-site installation of vibration-damping supports and precision leveling processes. Serving as...Read more -
Material Selection for Optical Bench Bases: Why “Physical Properties and Micro-Stability” Are the Core Key to the Ultra-Precision Industry
In modern ultra-precision optics, laser processing (such as femtosecond and picosecond laser systems), optical inspection (AOI), and semiconductor equipment, optical bench bases play a crucial role akin to the “human skeleton and foundation.” An excellent optical bench base must not o...Read more -
Granite vs Cast Iron vs Ceramic vs Mineral Casting for Machine Bases
Choosing the base material is one of the most consequential decisions in precision machine design. The base carries the guideways, the drive system and the workpiece, and it quietly determines thermal drift, vibration behavior and how long the machine holds its accuracy. The four dominant candid...Read more -
Granite Surface Plate Grades Explained: DIN 876, ASME B89.3.7, GB and Federal Spec
When a quality department specifies a granite surface plate, the single most important line on the drawing is the grade. The grade defines the flatness tolerance the manufacturer must certify, and it directly determines whether the plate is suitable for calibration work, incoming inspection, or ...Read more -
Granite Bases Resist Oxidation and Keep Reference Surfaces Intact for Long-Term Use in Laboratory Environments
Precision metrology platforms and optical inspection stations in laboratories operate year-round under constant temperature & humidity or ventilated conditions. Many metal reference platforms gradually suffer corrosion and oxidation peeling after long service. Oxide particles form on the surf...Read more -
Fine-Grained Granite Bases Deliver Higher Smoothness of Reference Surfaces after Grinding
In the field of ultra-precision measurement and equipment assembly, many buyers focus heavily on flatness when selecting granite bases, while overlooking the profound impact of the stone’s internal grain structure on the final smoothness of reference surfaces. Even with identical grinding procedu...Read more -
How to Protect Reference Surfaces from Damage during Transportation for Export Packing of Granite Bases?
Granite bases are high-value ultra-precision components. Long-distance overseas sea freight involves multiple hoisting, transshipment, bumping, and fluctuations in temperature and humidity. Once the ground reference surface of the base suffers bumps, scratches, indentations or cracks, it will los...Read more -
Will Granite Bases Suffer Precision Drift under Alternating High and Low Temperature Environments?
When selecting granite bases, many precision equipment integrators often have one concern: if the equipment operates under conditions with large day-night temperature differences or alternating cold and heat, will the base produce precision drift as temperature changes repeatedly? Outdoor semicon...Read more -
Granite Inspection Tables Can Be Customized to Required Dimensions to Match Inspection Workstations
In the planning stage of precision manufacturing production lines, many enterprises directly purchase standard-size granite inspection tables. Later, they find that the table length, width, support points and hole layout are incompatible with on-site inspection workstations. Either the tabletop i...Read more -
Granite Inspection Tables Resist Vibration and Are Suitable for Dimensional Inspection of Precision Workpieces
In micron and even nano-level dimensional inspection of workpieces, vibration acts as the most hidden precision killer. Micro-vibrations transmitted from the ground, caused by running workshop fans, reciprocating movements of automated equipment and personnel walking, will propagate to the inspec...Read more
