The Professional Line punching machines by EHRT are characterised by their outstanding robustness even under high loads. With the Professional machines a three-shift operation, for example, is not an issue. This machine is fitted with three CNC controlled axes, allowing for production parts to made with virtually perfect accuracy. No additional employees are needed to adjust the machine, which saves a significant amount of time. The operator is only responsible for starting the machine, feeding in the material and then removing the production parts. Feeding in the material and removing the production parts can be further automated. This makes the machines extremely cost-effective. Software solutions from EHRT enable a customised and smooth production flow of punching machines. In addition, the punching machine can be optimally linked with the bending machine so that production can be carried out based on a single production file from a common database.

The new FlexPunch series features a very flexible and modular system. Each machine can be adapted to the customer’s individual requirements via individual components. The FlexPunch series is equipped with three CNC controlled axes, allowing for production parts to made with virtually perfect accuracy. No additional employees are needed to adjust the machine, which saves a significant amount of time. Through additional options, however, the processes of feeding the material and removing the production parts can be further automated. This makes the punching machines extremly cost-effective.

AMZ stands for automated material loading. AMZ enables automated loading of metal bars into our punching machines. Different materials types (thickness/width) can be processed successively. This only requires a short manual intervention when changing the type of metal bars, which allows for an ideal preparation of the production process. As soon as the machine has been started, the operator no longer needs to deal with feeding in the material, and can sort and further process the production parts during this time. The AMZ can also be seen as a small intermediate storage facility.
