1. The above table is a storage example for reference purposes. The number of items that can be stored depends on the shapes of the dies.
2. The maximum maximum height is the height when a 60 mm high 1V die is stored in the punch bottom.
3. The punch weight (maximum per row) is the maximum weight converted to the L size length.
4. A press brake punch clamp groove in the punch is required.
5. Die bases, such as DHC and 1VHB, can also be stored in the die storage unit.
Items with a 1V die bottom width that exceeds 60 mm cannot be stored.
6. The maximum die height is the height when there is bottom shelf storage.
7. The die arm stops automatically when one of the following is selected/started: Middle: press brake table top height,
Top shelf: 60 mm above the middle position (DHC die base top surface),
Bottom shelf: 223 mm below the middle position.
8. A separate power supply (200V, 3-phase, 1KVA) from the press brake is used.
9. There is also a die base with rollers (option) that makes it easy to move dies on the die base. Patent pending
