lõualuku

Lõualuku is an Estonian term that generally refers to a locking mechanism for a jaw, typically in the context of a vice or a clamp. It describes the system that secures the movable part of the jaw in place, preventing it from sliding or opening unintentionally. This is crucial for maintaining pressure and stability when holding an object.

The specific design of a lõualuku can vary depending on the tool. In a bench vice, for example, it might involve a screw mechanism with a handle that, when tightened, wedges a nut or other component against a guiding rod, thus locking the jaw's position. For smaller clamps or specialized tools, the lõualuku might utilize a simpler lever or cam system to achieve the same effect. The primary function remains consistent: to provide a secure and adjustable grip.

The term emphasizes the act of "locking" the jaw, highlighting the rigidity and security it provides. This is essential for tasks requiring precision and force, such as woodworking, metalworking, or any situation where an object needs to be held firmly in place for manipulation or processing. The effectiveness of a tool often depends on the reliability and ease of operation of its lõualuku.
