The core competitiveness of the ultra-precision manufacturing industry lies in stable and reliable reference carriers. Thanks to comprehensive properties such as high rigidity, low thermal expansion and excellent vibration damping, granite structural components have become indispensable core base parts for high-end precision equipment. Many R&D and procurement personnel wonder during equipment design: what types of precision equipment can granite structural components fit? Drawing on years of experience customizing ultra-precision components, ZHHIMG sorts mainstream application scenarios for granite structural components according to accuracy requirements, load characteristics and working conditions of different equipment, helping manufacturers quickly match solutions for bases, gantries, beams, measuring tools and other granite components.
Metrology and inspection equipment represents the most classic application field for granite components. Such equipment imposes extremely strict requirements on reference flatness, straightness and long-term stability. For coordinate measuring machines, optical comparators, profile meters, tool presetters and other devices, their bases, columns and beams are mostly made of granite structural parts. Tiny vibrations or thermally induced deformation during continuous scanning will directly affect measurement results. Granite components can stably carry optical lenses and probe assemblies and absorb vibration generated by movement, ensuring long-term non-drift of measurement benchmarks. Granite measuring tools such as various metrology calibration platforms, standard reference rulers and V-blocks also rely on the stable physical properties of stone to provide traceable benchmarks for metrology laboratories, widely adopted by metrology institutes and university laboratories at all levels.
Semiconductor and optoelectronic inspection equipment is the fastest-growing application area for granite components. Various inspection devices, XY linear motor motion stages, lithography supporting modules and perovskite coating machines in semiconductor production lines adopt granite bases and gantry frames as main supporting structures. Semiconductor inspection includes AOI visual inspection, X-ray flaw detection equipment and industrial CT. Imaging systems are extremely sensitive to micro-vibration; any slight jitter will blur images and cause false inspection judgments. The high damping characteristic of granite isolates internal motion vibration and external ground disturbance and stabilizes optical imaging units. PCB drilling machines and circuit board inspection equipment also utilize granite bases to maintain positioning accuracy during high-speed drilling and scanning.
Precision laser processing and inspection equipment set strict requirements on the thermal stability of base materials. Ultrafast laser equipment such as femtosecond and picosecond lasers is used for micro-cutting, micro-machining and precision inspection. Minor offset of the laser optical path will greatly reduce product yield. Granite structural components feature an ultra-low thermal expansion coefficient and barely deform under slight ambient temperature fluctuations, keeping optical paths aligned over long periods. Whether for laser cutting, laser marking or laser interference inspection equipment, granite bases, gantries and beams serve as stable mounting carriers for optical modules and support long-duration continuous operation.
Precision inspection equipment in the new energy sector also extensively adopts granite components. Dimensional inspection, pole piece appearance inspection and battery module positioning measurement equipment in lithium battery production work under complex conditions, and some workshops contain coolant and dust. Granite components resist rust and require simple maintenance, retaining benchmark accuracy continuously and suiting on-line inspection stations of lithium battery production lines. Meanwhile, various new energy material experimental platforms and precision material mechanical test benches also use granite platforms as reference bearing structures.
High-end CNC and precision motion equipment also cannot function without granite structural parts. Traditional cast iron beds are vulnerable to temperature and rust, while granite beds and T-slot platforms can be applied to precision CNC machines and comprehensive guide rail & lead screw testers. Linear motor XY motion stages and high-precision positioning slides mount guide rails directly on granite bases, leveraging the stone’s high rigidity to suppress dynamic deformation during movement and improve positioning repeat accuracy. 
The form of granite components varies for different equipment. Some devices only require flat plate bases, while gantry optical and inspection equipment demands large granite gantries and bridge components. Certain assembly stations adopt granite bases with pre-embedded T-slots for flexible module installation. ZHHIMG can machine integrated oversized granite components to meet customized demands ranging from small laboratory measuring tools to heavy-duty large gantry equipment. All products are inspected by a full set of metrology instruments and comply with multiple international metrology standards.
It should be noted that granite is not suitable for all equipment scenarios. Re-evaluation is required if equipment undergoes continuous severe impact or long-time immersion in strong corrosive chemicals. For most equipment scenarios pursuing micron and nanometer positioning and measurement accuracy, granite structural components are the preferred option due to unique material advantages.
