Oneway Live Center adapter - 3941-255 - Rotating counter center

Oneway Live Center adapter (3/4" - 10 tpi on M33) fits the thread. Using the adapter, for example, a chuck with the Live Center can be picked up and fixed in the head. With this technique, a head-mounted workpiece, the bottom of which has already been turned, can be aligned and fixed exactly concentrically on a chuck. The tolerance that occurs during the usual clamping of the workpiece can thus be avoided.
