What are merits and demerits of machine vice?

Merits of a machine vice include precision clamping, which ensures workpieces are securely held for accurate machining, and versatility, as they can accommodate various shapes and sizes. Additionally, they are typically easy to operate and adjust, enhancing productivity. However, demerits include the potential for limited jaw opening, which may restrict larger workpieces, and the risk of damage to softer materials due to excessive clamping pressure. Over time, wear and tear can also affect the vice's accuracy and performance.
