Introduce machine tool accessories, tool table screws

Machine tool accessory tool table screw is an important component used to fix the machine tool table. The following is an introduction to it:

Category

Hexagonal bolt: The head is hexagonal and is used in conjunction with a nut to secure the tool holder. It is commonly used to fix the tool holder in ordinary machine tools and comes in specifications such as M8, M10, M12, etc.

Square head screw: The head is square and can provide a large torque to prevent the screw from slipping during tightening or loosening. It is commonly used in tool holders that require high tightening force, such as those on CNC lathes. Common specifications include M8, M10, M12, etc

Tightening screw: also known as top screw, used to fix the tool or other components on the cutting table to prevent displacement during the machining process. One end of a set screw usually has a hexagonal or other shaped head for tightening or loosening with the appropriate tool

Specifications

Metric specifications: Commonly used ones include M8 × 35, M10 × 40, M12 × 50, etc.

. Among them, M represents metric threads, and the numbers represent the nominal diameter of the thread and the length of the screw, respectively, in millimeters

British specifications: Common ones include 1/4-20UNC, 3/8-16UNC, etc. Among them, 1/4, 3/8, etc. represent the nominal diameter of the thread, measured in inches, while 20, 16, etc. represent the number of teeth per inch

Material

Carbon steel: relatively low price, with definite strength and hardness, can meet the fastening needs of general cutting tables.

. Common ones include Q235 carbon steel, 45 # steel, etc

Alloy steel: added with alloying elements such as chromium, molybdenum, and vanadium, it has high strength, hardness, and performance, and is suitable for use in high-speed cutting, heavy-duty machining, and other occasions for tool table screws

Stainless steel: It has good corrosion resistance (based on actual reports) and oxidation resistance, and is suitable for cutting tables that work in humid and corrosive environments, such as machine tool cutting tables in industries such as food processing machinery and diagnostic equipment manufacturing
