What is a cylindrical mandrel? It is generally used in what kind of artifact?

A mandrel is a rigid cylindrical mandrel, which is directly cylindrical surface of the workpiece datum hole positioning. Mandrel cylindrical hole is often used with the reference hole basis (h6.g6.f7) several complexes to facilitate loading and unloading of the workpiece. Because it is a clearance fit, it will produce gap, so poor centering accuracy. Like (H7 / h6) with the cylindrical inner mandrel, the workpiece concentricity tolerance after processing at best only reach 0.03mm, so the cylindrical mandrel more geometric tolerances applied to the lower requirements of the workpiece. Cylindrical mandrel structure simple and easy to manufacture, easy to use for small batch production requirements of the workpiece, is still one very effective lathe fixture.
