UNPARALLELED LTD is one of the leading manufacturers and suppliers of granite v-blocks for aerospace in China. With abundant experience, we warmly welcome you to buy advanced granite v-blocks for aerospace made in China here from our factory. We also accept custom orders.
PRODUCT DETAILS
Granite V-Blocks are essential tools for precise positioning, inspection, and marking of cylindrical parts. Manufactured from high-quality natural granite, these blocks are engineered to deliver superior dimensional stability, excellent wear resistance, and long-term performance under demanding workshop and laboratory environments.
Key Features:
Exceptional Precision:
Each granite V-block is crafted to meet strict tolerance standards, ensuring excellent flatness, parallelism, symmetry, and squareness. Precision grades are available down to 1 μm depending on the size and configuration (e.g., 40×90 mm to 160×90 mm).
High Rigidity & Stability:
Granite is inherently stable and non-magnetic. Unlike metal blocks, it does not deform under temperature changes or magnetic influence, ensuring consistent accuracy during measurements.
Wear & Corrosion Resistance:
With strong resistance to abrasion and chemical corrosion, granite V-blocks are ideal for long-term use in harsh working environments without losing accuracy.
Non-Burring Surface:
The fine-grained structure of granite results in a smooth, burr-free surface that won't damage delicate components or measuring tools.
Custom Sizes Available:
Standard sizes include 40×90 mm, 63×90 mm, 100×90 mm, and 160×90 mm. Custom dimensions can be manufactured upon request to meet specific requirements.
Typical Applications
Precision measuring and inspection of cylindrical parts
Clamping and aligning components in machining processes
Use in metrology labs, tool rooms, and production lines
Suitable for both horizontal and vertical mounting
