What is the purpose of a "vise" in milling?

The primary purpose of a vise in milling is to securely hold the workpiece in place during the milling process. A vise provides a stable and firm grip, which is crucial for accurate machining. When milling, the cutting tool exerts significant forces on the workpiece, and if it is not properly secured, it can shift or move, leading to inaccuracies in the cut, potential damage to the piece, or even accidents.

Having a reliable vise enables machinists to perform tasks like contouring, cutting, drilling, or any operation that requires precision. By keeping the workpiece firmly in place, the vise allows for better control during the milling operation, ensuring that the dimensions and surface finish meet the desired specifications. This stability is essential for achieving high-quality results and maintaining safety standards in a milling environment.
