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. 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
Work pieces punching professional

Work pieces

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

Clamping

  • 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

  • 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
MultiTool

MultiTool

  • TThe especially developed MultiTools can punch holes up to 20 mm/0,75″ into a material thickness up to 13 mm/0,50″
MaxiTool

MaxiTool

  • The MaxiTool enables punchings up to ∅ 56 mm into a material thickness up to 20 mm. The machine can be equipped with up to 25 tools
To label the workpieces

To label the workpieces

  • A printer can be installed, which is controlled in your network via the EHRT software
  • An industrial inkjet printer labels the work pieces as they are fed through the machine
  • A special station engraves information on the workpieces, which are even readable after a surface coating
  • Alternativwly you can print the information on a label with a barcode

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

Networking

  • Networking with other EHRT machines and external workstations is supported. When net- working with one of the EHRT bending machi- nes, the bending axes are also visible and avai- lable for reference
EHRT Nesting Software

EHRT Nesting Software

  • The Nesting Software PunchPro is based on standard EHRT Software
  • Lengthening of the bars due to the bending pro- cess utilizes the material to it ́s fullest potential
  • The handling is very simple. All production applications are sorted and optimized automatically depending on the material
  • In cooperation with fully automated EHRT machines, you will be able to greatly increase your productivity
Punching software PowerCut

Punching 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
  • Special punching programs
  • For faster programming of work pieces the following extra programs are available:
  • Nibbling
  • Divided Circle
  • Hole Circle
  • One-sided and double-sided notching
