Sigma Pro is a high-speed electronic key cutting machine for bit, double bit, pump and special, angular cut keys.

The graphic interface and colour touch screen controls make it easy to use for any operator, and, at the same time, give access to advanced software tools that are essential for the more expert and demanding users.

The original key is read quickly and the ready installation of the blank, without further adjustments and without the use of any tools, make the key cutting cycle quite short. The bitting is read in a few seconds, thanks to the machine's innovative visualisation system, that can recognise and correct automatically the shifts and inclination of the key as against the optimal position. A second, in-depth reading function is also available, that makes it possible to make several corrections, in the case of worn or damaged keys, while the key is being cut.

The key to be read is locked in place by a single-locking point clamp.

Sigma Pro can cut a wide range of keys, thanks to the additional, easily exchangeable clamps.

The USB, Ethernet and serial ports configuration makes it possible to connect the machine to external multimedia systems, thus simplifying the software and database updates.

Its next generation software includes several very useful functions, including the management of multiple users, the saving of the cut keys, the importing of customised data, an on board user manual and the possibility of downloading the updates from the net.

The Liger software developed by Keyline stands out for its capacity to process every cutting system and easily receive software updates. Complex operations are made extremely simple and intuitive thanks to the modern color interface, which is simple and easy to learn.

The Card Maker function makes Sigma Pro indispensable for any locksmith. The machine has multilingual support and is versatile and appropriate for the international market.
