The external cylindrical turning tool is a cutting tool used for machining the external cylindrical surface on a lathe. Its features and structure are as follows:

1. Blade type: External cylindrical turning tools typically use replaceable blade designs, which are easy to replace and maintain.

2. Materials: Blades are typically made from high-quality materials such as tungsten carbide or high-speed steel to ensure cutting performance and wear resistance

3. Tool structure: Blades with different shapes and angles can achieve different cutting effects during turning, such as rough turning and finish turning.

4. Tool holding method: External turning tools are usually equipped with fixed clamping devices to ensure the stability of the tool during the turning process.

5. Nose radius: Depending on the machining requirements, external turning tools can choose inserts with different nose radii to meet the turning needs of cylindrical work with different diameters.

Scope of application:

1. Metal Processing: External cylindrical turning tools are widely used in the metal processing industry, including the external cylindrical shape processing of metal materials such as steel, alloy, and copper.

2. Mechanical Manufacturing: In the field of mechanical manufacturing, external turning tools are used for precision machining of the external surfaces of various mechanical parts, such bearings, shafts, etc.

3. Automobile manufacturing: External turning tools are commonly used in the automobile manufacturing industry to machine the external cylindrical shapes of parts such as engine crankshafts hubs.

4. Mould manufacturing: External turning tools are also commonly used in the mould manufacturing industry, for processing the external cylindrical shapes of plastic moulds, dieasting moulds, and other mould components.
