1. Definition and usage scenarios of precision vise and bench vise

Precision vise and bench vise are common manual fitter tools, used to clamp various objects, and are one of the necessary tools in industries such as industry, manufacturing, and maintenance.

The jaws of precision vise are generally straight, with a flat appearance, and the relative positions on both sides of the jaws are basically the same; while the jaws of bench vise are V-shaped, with a slightly curved appearance, and the positions on both sides of the jaws are asymmetrical and one side is biased.Due to the different jaws, the two pliers are suitable for different work situations：

Precision vise are mainly used to clamp flat objects, such as straight strips, flat-shaped items, or fastening screws; bench vise are mainly used to clamp round or irregularly shaped objects, such as pipes, special-shaped parts, etc.

2. The difference and characteristics of precision vise and bench vise

1.Clamping objects have different shapes: precision vise are suitable for clamping flat and straight bar-like items, while bench vise are suitable for clamping tubular, spiral, and irregularly shaped items.

2.The jaw shapes are different: the jaws of precision vise are completely symmetrical and straight, while the jaws of bench vise are V-shaped, with a large offset from the left and right, which makes it easy to clamp round items.

3.The strength and clamping range are different: the clamping force of the jaws on both sides of the bench vise is stronger and the clamping range is wider. Compared with the flat-nose vise, it is more suitable for work that requires vigorous clamping of items.

4.Different usage scenarios: Due to different shapes and clamping forces, precision vise are mainly used to fasten screws, fixture items, and clamp or move some thinner molds and parts, while bench vise is mainly used in the production and processing of electronics, machinery, automobile manufacturing, aviation maintenance, and sheet metal processing. Usually, bench vise is used when clamping round objects or tubular objects, which has the advantages of good stability and high clamping force.

3. Problems to pay attention to when using precision vise and bench vise

1.Precision vise or bench vise must keep the jaws clean and not corroded when used, otherwise it will affect the clamping effect.

2.When using, hold your hands in the appropriate position and do not put your fingers within the range of the clamp to avoid danger.

3.During use, the clamping force should be adjusted according to actual needs, not too tight or too loose, so as not to cause damage or undue stress to the clamped items.
