    摘要： This pneumatic machine tool comprises a telescopic spindle (18) having a drive shaft (28) driven in rotation by a pneumatic motor (14) and on which is slidingly mounted a hollow shaft (36) with which a tool holder (30) is associated and which is driven in translation by control means (24) comprising a carriage (38) driven in translation by an endless screw (42) via a nut (40) carried by the carriage (38), the said endless screw being driven in rotation by an electric motor, and is characterized in that the carriage is provided with a force sensor (52; 55) designed to measure the thrust exerted on the tool holder (30) and connected to a central processing unit in which is stored an algorithm for processing the signal delivered by the sensor and for monitoring the advance of the tool carried by the spindle.

    摘要： The invention is a tapping attachment of a type having free axial float and automatic depth control. The attachment embodies precise adjustment means for precisely adjusting or controlling the point at which the depth control will release. The depth control includes releasable engagement members movable relatively axially to release. The control means comprises an adjustable limiting member which precisely controls or limits the amount of inward positioning of the driven part of the engagable means relative to the driving part and thereby sets the amount of outward relative movement of the driven part which will cause release. The adjustable limiting means embodies a spring to insure against damage occurring to the attachment in the event the tapping element should encounter the absence of a hole to be tapped.
