A tapping unit (1) includes a protection device (12) for permitting an axial retraction movement of a master screw (4) towards the interior of a casing (2) from a reference position into a first proximal backward position with a first defined penetration stroke during which a first elastic return device (13) constantly returns the master screw (4) to its reference position. The protection device (12) furthermore permits an additional axial retraction movement of the master screw (4) towards the interior of the casing (2) from the proximal backward position into a second proximal backward position with a defined penetration stroke during which the master screw (4) is no longer returned towards the exterior of the casing (2).

Tapping device (1) comprising a workpiece support (4) for the workpiece that is to be tapped, running substantially in a horizontal plane in transverse (I-I) and longitudinal (II- II) directions, and comprising a moving head support (5) substantially parallel to the workpiece support (4) for the workpiece that is to be tapped, movable at least in terms of translation in a vertical direction (III-III) with respect to the workpiece support (4) for the workpiece that is to be tapped between a proximal tapping position and a distal clear position. Deformable articulated parallelogram means (7) allow the moving head support (5) to be moved rapidly between its proximal tapping position and its distal clear position.

In an integrated cutting and tapping tool, a part in the form of a strip (6) is held on a strip support (4) with a hole (7) facing a tap (14) carried by a tapping tool (11). The bottom dead center point of the tap (14) is detected by a feeler (15) associated with a multiplier lever (19) pivoting about a transverse shaft (22) and pulling on a transmission cable (17) whose free end is detected by position detection means (18). In this way the position detection (18) means may be moved out of the tool platen (1), so that the plunger (23) and the multiplier lever (19) constitute an assembly that is easy to integrate under the tapping area. The machining of defective tappings is detected in this way.
