3100kg/m³ High Density Black Granite Measuring Tools | Nano Precision, ZHHIMG
A granite surface plate that reads “Grade 00″ on its certificate should, in theory, be interchangeable with any other Grade 00 plate on the market. In practice, QC engineers know this isn’t always true. Two plates can carry identical flatness certifications and still behave diff...Read more -
Fully ISO & CE Certified Ultra-Precision Parts Supplier | ZHHIMG Group
When a new supplier is added to an approved vendor list, the certification documents rarely get more than a glance during the RFQ stage. But for QC engineers and procurement managers who have sat through a failed incoming-inspection batch, or explained to an auditor why a “certified” ...Read more -
Non-magnetic and Rust-free Granite Structural Components Adapt to Working Conditions of Semiconductor Inspection Equipment
Semiconductor inspection equipment imposes extremely stringent dual requirements on the environment and base materials. On one hand, precision sensors, optical imaging elements and probe modules inside the equipment are highly susceptible to magnetic interference. Faint magnetism can cause probe ...Read more -
High Damping Characteristics of Granite Structural Components Effectively Reduce Equipment Vibration Transmission
During the operation of ultra-precision equipment, vibration stands as one of the most troublesome interferences affecting micron and nanometer-level accuracy. Self-excited vibration generated by high-speed start-stop and reciprocating reversing of internal moving axes, as well as external ground...Read more -
Will Granite Structural Components Suffer Accuracy Degradation after Long-Term Use?
During the selection phase for ultra-precision equipment projects, equipment manufacturers and laboratory engineers focus on one key question: will the reference accuracy of granite structural components gradually decay after years or even decades of continuous service? Having witnessed low-cost ...Read more -
