Precision-machined components with a V-shaped groove are used for securing cylindrical workpieces during operations like drilling, milling, grinding, or inspection. These tools provide accurate alignment and stable support, especially for round stock, shafts, and pipes. They are often paired with clamps and other fixtures for enhanced security.
Their use is crucial in ensuring consistent and accurate machining processes. The design allows for self-centering of cylindrical parts, minimizing setup time and reducing the risk of errors. This robust method of workholding dates back to the early days of industrial machining and remains a cornerstone of modern manufacturing practices due to its simplicity and effectiveness.
