V-blocks are precision tools commonly used to hold cylindrical workpieces during machining, inspection, or marking operations. Made from hardened steel, these blocks are usually square or rectangular and feature a V-shaped groove running along the length of the block. The groove is designed to cradle round or cylindrical objects, providing stable support and alignment.
In use, V-blocks are placed on a flat surface like a milling machine table or inspection plate, and the cylindrical workpiece is laid into the V-groove. This setup allows the workpiece to remain securely positioned while being worked on, whether for drilling, grinding, or measuring. The V-shape is typically at a 90-degree angle, making it versatile for holding a range of diameters. Some V-blocks come with clamps to hold the workpiece firmly in place, ensuring no movement during the operation.
V-blocks are essential in ensuring accuracy, especially when working with round or irregularly shaped objects. The groove centers the workpiece, allowing for precise measurements or machining along its length. These blocks are often used in pairs to support longer workpieces, ensuring they remain level and aligned. Their ability to hold objects securely and maintain precise positioning is crucial in maintaining consistency and quality in precision tasks.
