FINN-power, represented in Australia by Advanced Sheetmetal Technologies , has released the C5 series of turret punch presses.

All material flow can be handled from one side, meaning it can be positioned anywhere in a plant, including a corner. An indexable upforming option eliminates sheet scratching, collisions, and bending of components.

Nibbling speed on 1mm centres is 1,100 hits a minute by a servo-controlled ram. Stroke speed and position which are fully adjustable in both directions. The servo-hydraulic punching system automates overload protection and provides flexibility for all kinds of punching, forming, and special applications. Available punching modes include punch, slow punch, soft punch, down-forming, and marking.

As many as 10 index stations can be installed for minimum setup times and a fast, flexible, and efficient fabrication process. The CNC index tool system is based on a single ac servomotor. The punch and die are mechanically engaged and disengaged.

Tool rotation can be programmed in 0.001º increments and throughout 360º rotation. A shorter path to the desired angle is automatically selected by the system. Full tonnage can be used in any index station with any tool size and at maximum material thickness.

The turret construction allows customer-specific turret layout and many indexing stations. Multiple tool stations allow up to 150 tools on the turret. Special applications like wheel technology and applications including diamond marking can be used. The machine makes automatic clamp settings by positioning sheet clamps individually, according to the NC program. When changing production from full size to small sheets, clamp setting can be made automatically without wasting operator time.

Clamps can be automatically set to their programmed locations to eliminate any possibility of punching the clamp. Dead zones can be eliminated with an optional third clamp and programmable clamp move function.

Sheet loading takes place with a simple push, regardless of sheet size. It is also takes place close to the table edge with four optimally positioned gauge pins. Sheet supports rise from the table to allow easy positioning of heavy material. Unloading of processed components is semiautomatic, as the machine places the component to a freely programmable position on the table.

The catch and carry work chute allows several components up to 500mm x 500mm to be stacked outside the machine. Siemens or Fanuc CNC control includes an Ethernet connection, modem, and fast NC-program downloading as standard. Options include PowerLink M, a user interface software and hardware system that includes an integrated industrial PC.

The compact express sheet load/unload system is a moving table allows fabricated sheets to be unloaded at the same time as new sheets are being loaded, giving rapid and uninterrupted cycle times. The system takes up little more room space a standard turret. It handles sheets up to 1250mm x 2500mm and bundles up to 150mm for loading and 250mm for unloading.

The loader is fitted to the rear of the machine, leaving the front of the machine available for manual loading and unloading of sheets and parts. The sheet loading table includes double sheet detection and automatic sheet referencing of every sheet loaded.
