Full-field Applications of Granite Machine Tool Bases (Granite Bases)Relying on six core characteristics—low linear expansion, strong vibration absorption, non-magnetic, rust-proof, zero internal stress, and high flatness—granite machine tool bases are exclusively used for micron/nanometer-level high-precision equipment. They are not suitable for general machine tools subject to heavy cutting impacts. They are divided into six major…
Granite Precision Inspection Platform —— Introduction to the Core of Constant Temperature and Precision Stability
Cast iron platforms offer superior static load-bearing and heavy-duty crushing capacity, but high-precision inspection and metrology demand temperature stability, low deformation, zero stress, vibration damping, rust resistance, and long-term accuracy maintenance. Granite completely crushes cast iron in the core requirements of precision measurement, and the application scenarios of the two are entirely separate. I. First,…
Technical Requirements for Flatness of Nanoscale Positioning System Bases (Granite / Marble Bases)Applicable Objects: Linear motor platforms, semiconductor inspection equipment, optical alignment platforms, nano-displacement stages, CMM core bases; Mainstream Material: Jinan Blue Granite.Core Logic: The system pursues nanoscale positioning (±1~100 nm), and the drives (linear motors, gratings, voice coil motors) can only correct dynamic motion…
Nanometer-level positioning accuracy: The drive determines the upper limit, while the base secures the bottom line.When positioning indicators enter the nanometer scale, many people fall into a cognitive trap: wanting to achieve nanometer-level motion by blindly pursuing high-end linear motors, ultra-high resolution gratings, and advanced servo algorithms. However, extensive field verification in semiconductor inspection, optical…
