Expansion Mandrel

Expansion mandrels are machine tool accessories used in metalworking machinery. They are designed to hold and support workpieces during machining operations.

Expansion mandrels consist of a hollow cylindrical body with internal threads and a tapered or conical shape. They are typically made of high-quality steel or other durable materials to ensure stability and precision during machining processes.

The main function of an expansion mandrel is to securely grip and center the workpiece, allowing for accurate machining operations such as turning, milling, drilling, or grinding. The internal threads of the mandrel are used to expand or contract the mandrel, adjusting its diameter to fit the specific workpiece being machined.

Expansion mandrels are commonly used in applications where a high degree of concentricity and precision is required. They are particularly useful for machining cylindrical or tubular workpieces, such as pipes, shafts, or sleeves.

Overall, expansion mandrels are essential tools in metalworking machinery, providing a reliable and efficient means of holding and supporting workpieces during machining operations.
