In case of scroll chuck, a workpiece is clamped by three or four jaws. On the other hand, when we use spring collets, a workpiece is clamped as wrapping in with the number of flexing slot of the collet. Therefore, since the pressure concerning one point ends few, it can clamp powerfully, without pressure's distributing and damaging the whole clamping portion of the workpice.
