A master key identification module is disposed in fixed relation to the master key clamping module and identifies a type of key secured in the master key clamping module.

Said clamping module (24) comprises means (26) for a rigid coupling thereof to the machining module (12).

A clamping station (31.3) comprising a pair of gripping rollers secure the proximal end of the board adjacent the saw station for sawing.

Said machine tool (10) also comprises at least one pallet changing module (28) which is connected to the clamping module (24) asymmetrically with respect to said midplane.

The invention concerns a pressure regulating assembly and a machine-tool clamping module, equipped with such a pressure regulating assembly, the clamping pressure being adjustable by means of a pressure reducer (1).

A clamping arrangement (88) is attached to the mounting structure to maintain the thermal head in operative position.
