Machine vise is a heavy-duty bench vise made of metal, which is connected to the top of the work space, unlike woodworking vise fixed to the side.Machine vise is also known as engineer vise, metalworking bench vise or fitter vise. The use of machine vise can increase a greater degree of stability, because the craftsman can work without holding the object.

The machine vise has a fixed jaw, a movable jaw and a screw to adjust the movable jaw. The jaws are screwed together with screws to fix objects.A typical machine vise jaw is 3-8 inches wide (about 7-20 cm), compared to woodworking vise, which is much wider, usually 7-10 inches (about 17-25 cm).The jaws of the vise may be lined with wood or plastic to avoid damage to objects, and some jaws have rough linings to prevent sliding.Other jaws are designed to accommodate a variety of shapes.

There are two main differences between machine vise and other vise: thick metal structure and installation.The machine vise is bolted to the top of the workbench, and its heavy metal structure allows it to withstand repeated and heavy strains.Depending on the base, the machine vise may have multiple functions.The advantage of a fixed base is to improve stability. However, when the machine vise will be used for various projects, the rotating base is suitable. The rotating base can be rotated 360 degrees, allowing the object to rotate in any direction.Some machine vise also rotate at an angle so that the object can be fixed obliquely instead of vertically.Although metal is usually used in work, machine vise can also be used to stabilize a variety of materials. It can be used for sawing, drilling, sand or gluing projects. The changes in its base and jaws make it a very versatile tool. Don't confuse machine vise with machine vise.Machine vise is installed on a machine and is usually used in an industrial manufacturing environment. Its jaws usually have a computer-controlled hydraulic or pneumatic release system. Mechanical vise is manually operated and is usually used in private workshops.
