What Is a Sign Vise?
A sign vise is a type of machine vise. A machine vise is a tool used to secure materials on a machine tool table so that they do not move when machining. Its structure is similar to a vise, and it holds the material in place by pressing down at two points.
A sign vise is a tool that can be inclined at a specified angle to hold the material in place. This inclination angle ranges from 1 to 45 degrees and can be freely set by the operator.
Uses of Sign Vises
Sign vises and other machine vises are necessary for various machining processes using machine tools, such as milling, drilling, grinding (surface grinding), and grinding machine processes. Since these machining processes are performed using motorized machines, it is important to hold the material securely so that it does not move during the machining process. This tool is mainly used to secure rectangular materials.
Since the sign vise can be changed to various angles according to requirements, it is also suitable for processing small items with precisely defined angles.
Principle of Sign Vises
As mentioned above, the sign vise is a tool that can fix the object to be processed at different angles. As they are used for processing metals and other materials, most of them are made of metal, and the angle range is from 0 to 45 degrees. Since they are relatively small and the space available for fixing is also small, they are basically used for precision machining of small products. Since it is a tool for processing with a defined angle, it is designed to have a very high angle accuracy. A tool with particularly high angular accuracy is sometimes called a “precision sign vise.”
Sign vises that are hardened to minimize deterioration and change over time are also available. Also available are those designed to be less prone to abrasion and angle changes during processing. Some sign vises use a trigonometric function table in order to use accurate angles. If you want to process with a strictly defined angle, it is important to use such a trigonometric function table, to confirm in advance how to calculate the appropriate angle for the product, and to fix the material securely to be processed so that it does not move even when it is angled and inclined.
