Punching Machine Holecut 40-4 CNC

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.

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.

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.

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.
