Do you know what is the cold heading?

Yes, cold heading is a mechanical processing process, also known as cold working, which is used to make steel bars, rebars, wires, rivets, etc.

The head shape of the screw during the production process is usually completed by a heading machine. The specific process is as follows: 1. Cut to length on the screw material, ready for threading. 2. Put the end with the thinner thread into the opening and pass it through the rotating round steel die. 3. As the die rotates, the thread finished.cold heading is a mechanical processing process, also known as cold working, which is used to make steel bars, rebars, wires, rivets, etc.

Common cold heading machine models are: 1. Z24 2. Z27 3. Z41 4. Z47 5. Z52 6. Z62 These models correspond to different diameters and lengths of threaded rod processing and different processing requirements. For example, the Z24 cold heading machine is suitable for processing threaded rods with a diameter of 2-4mm and a length of 25-50mm, while the Z62 type is suitable for processing large threaded rods with a diameter of 28-62mm and a length of 350-550mm.

There are mainly the following types of cold heading abrasive tools: 1. Grinding wheel: Grinding with a grinding wheel, often used for rough machining and reshaping. 2. Polygon grinding tool: It is used to grind threads with multiple precision-processed corners, which is suitable for fine processing and high-precision processing. 3. Scraping Abrasives: Thread cutting through scrapers with geometric shapes, suitable for high-speed machining and thin-walled parts processing. 4. Rotary grinding tool: it is rotated by the long axis, and thread processing is performed after the blade is extended, which is suitable for processing large nuts or bolts. 5. Honing tools: honing tools are used for grinding, which is suitable for micro machining and machining for specific machining measurement requirements. Different types of cold heading abrasives are suitable for processing different materials and workpieces, and should be selected according to needs.
