Carrier gripping small-diameter arbor for grinding in machine with fully-automatic loading system, includes four leaf-spring jaws for gripping and centering

摘要

The carrier is a toothed circular disc (1), with leaf springs (5) extending from the circumference towards its center. The arbor is gripped and centered by at least three springs (preferably 4) of the carrier. The spring center lines are directed towards the center of the disc. The free head ends (7) of the springs include circular arc (6) configurations, concentric with the disc center (9) and having a diameter corresponding with that of the arbor. The springs are about 0.25 mm thick. The carrier is made in a single operation by electrical erosion.
