Inner Diameter Clamping for Complete Outer Diameter Access

摘要

Gripping a workpiece by its inner diameter (ID) rather than its outer diameter (OD) is a work-holding option that many job shops fail to consider when turning or grinding parts. However, this technique offers a number of advantages, especially in the machining of workpieces with complex surfaces. Royal Products (Hauppauge, New York) produces a series of CNC expanding mandrels designed for a range of spindle types that it says offers more flexibility in workholding than people might think.
