定义
A precisely machined pattern of tapped holes arranged in a uniform grid on granite tables or bases, providing standardized mounting points for fixtures, workholding devices, and accessories in precision manufacturing and measurement applications. The grid pattern ensures repeatable positioning and alignment across the entire working surface.
工作原理
The grid pattern provides a coordinate system of mounting points that allow fixtures and components to be positioned at precise locations. Threaded holes accept bolts to secure items, while the granite's dimensional stability maintains accuracy over time and temperature variations.
材料
Granite (typically black or gray granite with fine grain structure)Grade A or better with minimal porosityhardness of 6-7 Mohsspecific density of 2.6-2.8 g/cm³.
Counterbore
Optional for flush mounting
Grid Spacing
25mm, 50mm, or 100mm standard intervals
Thread Class
6H for metric, 2B for imperial
Thread Depth
1.5-2 times bolt diameter
Hole Diameter
M6, M8, M10, or 1/4-20, 5/16-18, 3/8-16 imperial threads
Surface Flatness
0.005mm per 300mm
Positional Tolerance
±0.05mm to ±0.1mm
标准
ISO 230-1ISO 10791-7DIN 876DIN 877

常见问题

What are the advantages of granite for tapped hole grid patterns?

Granite provides exceptional dimensional stability, vibration damping, thermal stability, and wear resistance, maintaining precision over decades of use in manufacturing environments.

How are tapped hole grid patterns manufactured on granite surfaces?

Using CNC drilling and tapping machines with diamond-tipped tools, following precise coordinate measurements. The process includes precision leveling, drilling, tapping, and quality verification of each hole position.

What maintenance do granite tapped hole grids require?

Regular cleaning to remove debris from threads, occasional verification of positional accuracy, and protection from impacts that could chip the granite around hole edges.
