Amada EM series with automatic tool changing system

The EM ZRT punching machine can handle large sheets without repositioning while minimising scrap.

The EM ZRT punching machine is a further addition to the existing EM punching machine series and boasts an ultra-modern suite of features: Punching drive with energy recovery capabilities, tool identification system and a brush table that makes use of intelligent punching machine technology.

The EM-3612 ZRT punching machine represents an extension to Amada’s proven EM punching machine series in the form of a turret punch press that is able to machine large sheets without repositioning. The four thread tapping stations integrated in the punching machine turret are automatically exchanged in the same way as the other tools. At the same time, this new punching machine provides higher punching speeds.

Unattended manufacturing with several hundred tools
Alongside the tool turret itself, the machine also possesses a setup turret that can be equipped with tools during machine operation and feeds the tools into the turret as required. The system is able to house up to several hundred tools. This solution thus makes it possible to cover all requirements and run complex jobs over a period of several days without any manual intervention. Thanks to the innovative tool ID, a barcode-based tool identification, the EM-3612 ZRT is able to access all the available tools and perform its own tool setups automatically. The system reliably identifies the current status of all the tools in terms of size, shape, angle and stroke rate. If necessary, it switches automatically to a replacement tool. Setup errors are eliminated, scrap is avoided and costs are reduced. And there is another special feature: The lower turret level is fully covered by an intelligent brush table. Only the tool that is currently being used is raised to the operating level. This permits scratch-free machining while maintaining a consistently high level of manufacturing quality.

When used in combination with the ID-TOGU tool grinding machine, the EM-3612 ZRB becomes even more productive than before. After each regrinding operation, the up-to-date tool data is determined and made available to the system. When the tool is used again after grinding, the punching system detects its status, knows exactly how much has been ground away and how the tool has to be controlled. The time-intensive manual transfer of the new tool dimensions to the system controller is no longer necessary.

The drive concept that saves energy
The Amada EM-3612 ZRT punching machine is equipped with the highly efficient servo-electric twin drive with energy recovery that is already familiar from the EM punching machine series. The energy that is released when the ram is decelerated is stored and then re-used for the next movement of the punching machine. In this way, the punching machine achieves extremely high stroke rates while simultaneously saving energy. With a punching force of 300kN, the punching machine average power draw is between 4.5kW and 5kW. Taken together with the minimal maintenance costs and times, this delivers of punching machine significant cost savings.
