Punching Machine

All Punching Machines of the Professional Line feature three CNC controlled axes. They are designed for high loads in an industrial operation. Extreme durability and unrivalled speed characterize the Professional line.

Our latest technology allows all 3 axes to be accelerated simultaneously with 6 m/s2 and travel at speeds up to 60 m/min. Flexibility and speed were the focus on developing the new machine. With a punching force of up to 80 tons, the new heavy duty machine is capable of punching material up to 20mm/3/4" thickness.

With the high speed of these machines,they have the capacity for 350 strokes per minute. You can have up to 32 punch tools installed at one time. Handling of material is maximized by utilizing only one punching machine.

The third CNC axis always moves the cylinder exactly over the tool which keeps the wear on the bearings and tools to a minimum. Multi-shift operation of the machine is guaranteed.

How it Works

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 6,000 mm). Once the desired number of work pieces is entered, the bar is pushed toward the stop. The machine works automaticly once the production process is launched.

All pieces are sent down a slat conveyor and are pushed sideways onto a table. Scrap is carried to the end of the conveyor. 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

The Punching Machines of the Professional Line processes flat profile bars up to 20 mm thick and 260 mm wide.Because of the wide range of tools and a variety of materials, the machine is ideal for automation. With options for an automatic feeding system, bus can be punched, marked, and sorted.

The completely automated Windows based software makes it easy to connect the different systems.

Punching Machine


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

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.

Punching Machine

Tool Change System

The linear tool carrier (y-axis) of the Professional Lines offers up to eight stations that hold up to seven 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.

To label the work pieces

A printer can be installed, which is controlled in your network via the 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 the latest add ones of punching machines a lot of customer requests were implemented and great importance was attached to the optimization of ergonomics.

Networking with other machines and external workstations is supported. When networking with one of the bending machines, the bending axes are also visible and available for reference.

Nesting Software

The Nesting Software Punch Pro is based on standard Software.Lengthening of the bars due to the bending process 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 machines, you will be able to greatly increase your productivity.

Punching-Software Power Cut

Easy Handling

The Microsoft Windows® based software Power Cut 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 menudriven software. Operators can soon program work pieces by themselves.

Power Cut 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.

Punching Machine

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

• Horizontal and vertical mirroring

• Chamfering corners up to 20 mm

• Rounding corners with Rmax = 25 mm (wider radiuses on request)

• Copy and modification programs

• Radiused cutting with Rmax = 30 mm (wider radiuses on request)

• Angular cutting

• Embossing

• Countersinking

• Embossing buttons

• Embossing digits and/or characters

• User-own macro programming


The machine features a cutting station to separate the work pieces after punching in one stroke.If work pieces are to be punched without cutting, this option can be disabled.

Program Storage

The program for each work piece can be stored as alphanumeric names up to 24 digits. More than 200.000 parts can be stored which can be located easily by using the search and sort options.

Software languages

German, English, Russian, French. Other languages on request.
