Granite vertical bases are widely used for installing sensors, camera modules and motion assemblies. Integrating precision‑machined mounting slots directly onto the granite body changes the traditional assembly mode of adding external metal brackets, bringing distinct processing and application strengths for precision equipment.
First, integrated slot machining eliminates accumulated assembly errors. Separately manufactured metal supports need repeated positioning, drilling and locking during equipment integration. Each connection link introduces tiny position deviation. Mounting slots are milled and finished directly on the granite substrate in one processing cycle. The relative position between slot datum and base reference face is guaranteed under unified clamping. It avoids position offset caused by bracket welding or bolt connection and improves repeat positioning accuracy of installed components.
Second, it helps maintain long‑term structural stability. External metal accessories have different thermal expansion coefficients compared with granite. Under ambient temperature fluctuation, mismatched deformation may lead to loose joints, tilt or datum drift. The integral‑formed mounting slot shares the same granite material with the whole vertical base. There is no heterogenous‑material interface. Thermal stress and gap variation at joint positions are greatly reduced, keeping mounting datum stable during continuous operation. 
Weight‑reduction and rigidity balance can be realised through slot profile optimisation. Reasonably designed mounting slots remove unnecessary material without weakening overall structural rigidity. Compared with thick solid bases, grooved structures cut dead‑load weight of vertical supports, which is helpful for equipment frame load bearing. Meanwhile, slot side walls serve as locating surfaces, delivering reliable positioning function without extra reinforcing parts.
It simplifies on‑site assembly and debugging work. The precision‑finished mounting slots provide direct locating reference. Operators can slide and lock modules along the slot for fine‑tuning, no extra auxiliary jigs are required. It shortens on‑site installation time. Especially for multi‑sensor stacked installation scenarios, multiple groups of mounting slots realise compact layout and save overall equipment space.
Special attention should be paid during processing. Slot side walls and corner positions need stress‑relief treatment after milling to avoid micro‑defects. Finishing for slot locating faces adopts progressive grinding process, ensuring straightness and surface quality of the groove. Each finished base completes full geometric inspection covering slot position, side‑wall perpendicularity and datum relation.
In short, granite vertical bases with integrated mounting slots excel in error elimination, thermal stability, compact layout and convenient commissioning. This integrated processing solution fits well for optical detection, semiconductor testing and other high‑precision equipment.
