Granite V-Block manufacturer

Product Identity

We are a dedicated manufacturer of precision granite V-Blocks,engineered for the highest levels of dimensional stability and measurement integrity.Our focus is on crafting master-grade reference fixtures for environments where conventional materials are insufficient.

Inherent Material Advantages

Our V-Blocks are precision-machined from selected natural granite,offering distinct performance benefits:

Thermal Stability:Exceptionally low coefficient of thermal expansion ensures minimal dimensional change across temperature fluctuations,critical for calibration and high-precision work.

Superior Damping:Granite's natural structure absorbs vibration effectively,providing a stable,quiet base for sensitive measurement and inspection tasks.

Long-Term Accuracy:The hard,non-porous surface resists wear and corrosion,maintaining its geometric integrity over decades of service.

Non-Conductive&Non-Magnetic:Ideal for specialized applications in electronics,laboratories,and environments where metallic interference is a concern.

Precision Engineering&Craftsmanship

Each granite V-Block is a product of meticulous fabrication:

Master-Grade Lapping:Critical surfaces—the V-grooves,sides,and base—are precision lapped to achieve ultra-fine flatness,exact perpendicularity,and precise angular accuracy.

Rigorous Verification:Geometry is verified against exacting standards,with documentation available to certify flatness,squareness,and angle tolerances.

Custom Geometry:Capable of manufacturing standard 90-degree grooves or custom angles to meet unique fixture or measurement requirements.

Custom Manufacturing Capabilities

We specialize in producing V-Blocks to exact customer specifications:

Tailored Dimensions:Manufactured to your required length,width,height,and V-groove depth.

Special Features:Can incorporate custom mounting points,threaded inserts,levelling feet,or reference edges for system integration.

Surface Finish Options:From standard lapped finishes to optical-grade polishing.

Material Selection:Options include fine-grained black granite for optimal stability and wear characteristics.

Primary Applications

Metrology&Calibration Labs:As master reference fixtures for setting standards,calibrating tools,and precise layout on surface plates.

High-Precision Manufacturing:For fixturing critical components in optics,aerospace,and semiconductor-related assembly.

Quality Control Stations:Providing an unchanging reference base for repeated inspection of cylindrical parts on CMMs or with manual gauging.

Research&Development:Serving as a stable platform for prototyping,testing,and experimental setups where environmental factors must be minimized.
