All EHRT punching machines in the Holecut 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.
Program the workpiece 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 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. 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. Different workpieces can be produced within one work cycle to optimize production.
The EHRT Holecut Professional Line punching machines rapidly process flat profile bars up to 16 mm thick and 200 mm wide with an option up to 260 mm wide.
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.
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.
The linear tool carrier (y-axis) has six stations that hold five 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 meaningless machine downtime.
A printer can be installed to print barcodes on either label or on the workpieces directly.
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.
