How it works

How it works

  • 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
Work pieces

Work pieces

  • The EHRT Holecut Standard Line punching machines rapidly processes flat profile bars up to 16 mm thick and 160 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
Punching area

Punching area

  • 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
Tool change system

Tool change system

  • The linear tool carrier (y-axis) has four stations that hold three 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. Punches and dies can be changed rapidly meaning less machine downtime

Continuous development

  • 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
Punching software PowerCut

unching software PowerCut

  • Easy Handling
  • The Microsoft Windows® based software PowerCut is very easy to learn. CNC programming skills are not required. All the punches in a work piece 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 work pieces 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
  • Program Storage
  • The program for each work piece can be stored as alphanumeric names up to 16 digits. More than 200.000 parts can be stored which can be located easily by using the search and sort options
  • Networking
  • Networking with other EHRT machines and external workstations is supported
  • Languages
