Doppia Libra

The Emmegi twin-head cutting-off machines boast of exceptional performance characteristics, including ruggedness and reliability. This machine is the ideal tool for cutting aluminium and PVC bars in various thicknesses and at different angles. Latest generation machines which can make a considerable contribution to the production cycle thanks to their high standard of accuracy and user-friendliness. Doppia Libra is a twin-head cutting-off machine with automatic movement of the right cutting head through a numerically controlled dc motor. The machine can be provided with an industrial label printer to enable profile identification and association with relative job.

Label printer

The industrial label printer allows each cut profile to be identified with identifying features from the cutting list. In addition, barcode printing enables easy identification of the profile itself, which is particularly useful for subsequent machining steps on Machining Centres or assisted assembly lines.

Doppia Libra Intermediate support Emmegi
Intermediate support

The pneumatic intermediate support is extremely useful when cutting light profiles of considerable lengths. In this case, the pneumatic support will, automatically, provide the ideal condition to support the profile. This accessory is available for all lengths, but is specifically recommended on machines having 5- and 6-meter useful cuts.

Electronic profile thickness gauge
This refined profile thickness control system enables automatic correction of the cutting dimension according to the actual size of the profile, with relative tolerance resulting from surface treatments such as painting, anodising, etc. The device can be used at the operator's discretion and in various modes according to different probing cycles resulting in correction of the entire cutting list, including the macrostructure formula.

Doppia Libra Mobile heads tilting Emmegi
Mobile heads tilting
Rotation of the heads around the horizontal axis is performed via pneumatic cylinders. The angles that can be obtained are from 90° to 45° outside for machines equipped with 450 mm diameter blades. With 500 mm diameter blades, angles from 90° to 22°30' outside can be achieved. Intermediate angles are obtained by means of a special stop that can be manually adjusted. Mobile units are equipped with integral pneumatic drop-down protections of the machining area.
Control
The control installed on the various models, designed for ease of use and sliding on bearings, allows correct positioning of the moving heads according to the specifications of the cut to be made. The machining cycle can be optimised by creating cutting lists, thereby reducing scrap and cycle times for workpieces loading-unloading.
