Program the work piece by entering the length of the bar of raw material and the computer automatically calculates the maximum number of pieces to be punched (for example 18 pieces of a bar of 6000 mm). Once the desired number of work pieces is entered, the bar is pushed toward the stop. The machine is fully automated once the production process is launched. All pieces are sent down a slat conveyor and are pushed sideways onto a table. Any scrap is carried to the end of the conveyor and dropped into a bin. The machine continues to run in this manner until a new work piece is programmed or selected. Just merely insert new material. Different work pieces can be produced within one work cycle to optimize production.
The EHRT Holecut Professional Line punching machines rapidly processes flat profile bars up to 16 mm thick and 200 mm wide with an option up to 260 mm wide.
The work piece is clamped laterally by an exchangeable transport gripper. The gripper pulls it through the machine along the x-axis in order to avoid damaging the work piece. In addition, the work piece is clamped sideways outside the punching area with each punching stroke which also allows the punching of slightly deformed material.
The great advantage of lateral clamping is that press cuts are allowed throughout the whole work piece including the border. This eliminates the restrictions of traditional clamping jaws.
The linear tool carrier (y-axis) has six stations that hold five punching tools and one cutting tool. All EHRT punching machines are equipped with a special plug-in system for a quick and easy change of tools. There is no need to screw anything together. The punch and die plate are adjusted to each other automatically. Punches and dies can be changed rapidly meaning less machine downtime.
A printer can be installed to print bar codes on either labels or on the work pieces directly.
During the development of our latest line of punching machines, customer requests and suggestions have been implemented. We also placed a great importance on optimizing ergonomics.

The Microsoft Windows® based software PowerCut is very easy to learn. CNC programming skills are not required. All the punches in a workpiece are shown on the screen making programming mistakes easily detected. When selecting a new piece, all the necessary tooling changes are displayed. Software training is minimized by the menu-driven software. Operators can soon program workpieces by themselves. PowerCut scans each program for possible collisions before transferring it to the control unit. This eliminates most handling errors. The software can be used in millimetres or inches.
The program for each workpiece can be stored as alphanumeric names up to 24 digits. Up to 200.00 parts can be stored which can be located easily by using the search and sort options.
Networking with other EHRT machines and external workstations is supported. When networking with one of the EHRT bending machines, the bending axes are also visible and available for reference.
Software languages: German, English, Russian, French and Finnish.
