Ball Transfers
Steel balls are mounted on the press bolster, allowing the die to be moved easily across the bolster surface. Once the die is positioned, the slide presses down on the die, and the die clamp secures it firmly onto the bolster. When the die needs to be moved, the clamp is released, and the internal spring of the ball lifter pushes the die upward from the bolster surface, enabling smooth movement on the ball transfers.
