bench vise is a general fixture used to hold workpieces. The bench vise is installed on the workbench to clamp workpieces stably and is an essential tool in the fitter workshop. The turntable-type clamp body can rotate to rotate the workpiece to the appropriate working position. Precautions for using a bench vise When clamping the workpiece, the workpiece must be tightened appropriately. The handle can only be tightened by hand, and no other tools are allowed to apply force. When working with force, try to apply force toward the fixed clamp body. It is not allowed to knock on the movable clamp body or smooth surface... This tool is used in flammable and explosive gas places. The material is aluminum bronze and beryllium bronze alloy. It is widely used in petroleum, chemical industry, and other environments with potential fire and explosion hazards. It is also an indispensable special tool for mechanical manufacturing and maintenance. Products made of these two materials can have explosion-proof functions, and the products made of beryllium bronze alloy can also have anti-magnetic functions. The explosion-proof tools currently produced, sold, and circulated in China can be divided into two categories based on materials: aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools. The specific material is based on high-purity electrolytic copper with appropriate amounts of aluminum, nickel, manganese, Iron and other metals form copper-based alloys. Beryllium copper alloy (commonly known as beryllium bronze) explosion-proof tools, the specific material is high-purity electrolytic copper as the matrix, adding an appropriate amount of beryllium, nickel and other metals to form a copper-based alloy. Both materials have very good thermal and electrical conductivity.
