What Is a Mandrel?
Mandrels are tools frequently utilized in machining and precision measurement. This term commonly refers to shafts or spindles that hold workpieces or objects during measurement or machining processes. A mandrel’s primary function is to secure the workpiece at the center, facilitating its use in machining or precision inspection. Additionally, mandrels serve as rotating axes for attaching tools, enabling operations like cutting, polishing, and, in dental applications, fitting grinding wheels.
There are various types of mandrels, such as flanged, tapered, and threaded, each serving different specific purposes. Mandrels are typically made from materials like steel, aluminum, or titanium, and they may receive special treatments to enhance their performance.
When using a mandrel, careful consideration should be given to selecting one that matches the workpiece’s shape and size. It’s also important to ensure that threads or tapers are undamaged and to set the rotation speed and torque correctly for safe and efficient operation.
