STANDARD LINE

The Holecut Standard Line was developed especially for efficient processing of metal stampings. It features high flexibility and production accuracy. The main areas of application are for small and medium runs. 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 workpiece is programmed or selected. Just merely insert new material.

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 workpieces is entered, the bar is pushed toward the stop. The machine is fully automated once the production process is launched.

WORKPIECES

The EHRT Holecut Standard Line punching machines rapidly process flat profile bars up to 16 mm thick and 160 mm wide.

CLAMPING

The workpiece 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 workpiece. In addition, the workpiece 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 workpiece 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 meaningless 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

EASY HANDLING

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.

PROGRAM STORAGE

The program for each workpiece 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.

Software languages: German, English, Russian, French, Finnish.
Other languages on request.
