CAST IRON VEE BLOCK
A cast iron V-block is a precision engineering tool with a V-shaped channel used to hold and support round or cylindrical workpieces during machining or inspection. They are made from durable, close-grained cast iron and are typically sold in matched, numbered pairs to ensure accuracy. Key features include precision ground surfaces, a
90∘ centered V-groove for a secure grip, and optional clamps for extra stability.
Description and features
- Material: Constructed from high-quality, close-grained cast iron for durability and rigidity.
- Shape: Features a V-shaped channel, typically with a 90∘ angle, designed to cradle cylindrical objects securely.
- Precision: The surfaces are precisely ground to be square and parallel, ensuring accuracy for machining, layout, and inspection.
- Pairs: Usually supplied as matched and numbered pairs to guarantee a consistent and reliable set for work.
- Clamps: Some sets include screw clamps to hold the workpiece firmly in place, which is especially useful for heavy jobs or preventing movement during operations like drilling or milling.
- Applications: Used in various machining and inspection tasks, such as holding round stock for drilling, milling, or grinding operations.
How to choose the right V-block
- When selecting a V-block, the 90∘ angle of the V should extend beyond the center point of the round workpiece to ensure a stable and secure hold.
- It is important to ensure the block is large enough to accommodate the workpiece, but the V-angle must go past the center to prevent marring the part.
