The positioning and clamping method for the inner hole of the core shaft in CNC machining

Internal bore locating with a precision mandrel is a fundamental technique for machining parts that require perfect concentricity between their outside diameter features and a pre-existing inner bore, such as gears, pulleys, or bearing housings. The mandrel itself acts as a rigid, single-point datum that transfers the inner bore’s exact centerline to the machine spindle, […]
