The ATT-series is of O-frame and is characterized by rigidity and high geometric precision. It features a capacity of 20 metric tons and is able to work in mild steel thicknesses up to 6,5 mm.
The well engineered mechanical parts in the H+L Hydraulic ram are manufactured according to high precision standards. The HS3 electronic stoke control is controlling the speed and stroke of the 30 tons hydraulic punching head.
The ATT-series is standard equipped with a thick turret tool holder, consisting out of 30 stations. It is standard equipped with 2 Auto Index "D" stations. An additional two auto-indexing stations are optional.
The ATT-series is standard equipped with the Siemens 802D SL operator control, combining all components of a CNC (NC, PLC, HMI) and drive control in a single unit.
Plate clamps for easy sheet movement
An important aspect during punching/nibbling operations is supporting the sheet while the X- and Y- axis are moving. The tables are not connected to the Y-axis and are not moving. The floating plate clamps move the sheet over the table. The table of the ATT-series offer a combination of balls and brushes, for easy and silent sheet movement.
When designing the ATT-series, the safety aspect has been specifically taken care of. This is done by means of a CE-approved optical detection-system that is placed around the machine working area.
