A timing element for a lubricant supply system is capable of using pneumatics for the time of delivery of lubricant for a preset duration. In one example, the timing element has a cavity having an entrance and an exit, a first piston and a second piston. The first piston and the second piston are disposed in the cavity. The first piston is coupled to the second piston in such that compressed air in the entrance of the cavity is capable of moving the second piston and closing the exit. A pneumatic timing element may be incorporated into a dosing unit that is capable of supplying an amount of lubricant in a mist to a plunger bushing of a machine tool without. The duration of the dosing may be controlled solely by pneumatics and may prevent excess pooling of lubricant in bore holes by shutting off lubricant delivery at a preset time.

A device for processing components, and in particular, sections for aircraft, includes a handling system that supports a holding frame. The holding frame includes at least one pressure stamp and/or at least one processing device or unit. By means of the handling system, the processing device is freely positionable in space in relation to the components. Preferably, in the region of the holding frame at least one connection element is arranged. Due to the connection elements, an essentially closed force ring is established between the holding frame and the components so that in an ideal case there is no longer any feedback of reaction forces to the handling system. The connection elements, the processing device and the pressure stamps can be movable by actuators and can comprise integrated force sensors and/or distance measuring sensors.

A boring arrangement is connected to a boring machine equipped with a boring bit for boring a hole in overlapping workpieces. The boring arrangement includes a first sleeve connected to the boring machine, and a second sleeve that is movably connected to the first sleeve so as to allow a relative motion therebetween in a boring feed advance direction. Biasing elements such as springs apply a biasing force between the first and second sleeves so as to exert a pressing force through the second sleeve onto a pressing sleeve connected thereto. The boring bit moves through the interior of the pressing sleeve to bore the required hole in the workpiece. Thereby, the pressing sleeve surrounds the boring site and is seated and pressed against the workpiece with a pressing force that is greater than the boring feed advance force exerted by the boring bit onto the workpiece. A suction arrangement sucks away boring chips and other swarf material arising during the boring process. Thereby, the accumulation of swarf material in the joint areas between the two overlapping workpieces is avoided, and there is no need to separate the workpieces to remove swarf material.

In order to facilitate and reduce the time necessary for clamping together and boring a hole through at least two workpieces that are to be joined together, for example by rivets or bolts, a portable clamping and boring apparatus carries out all necessary operating steps once it is manually positioned at the intended location of the bored hole. The clamping and boring apparatus includes a tool body with a clamp device and a boring device mounted thereon. The clamp device includes a clamping yoke with a clamp jaw element at an end thereof, and a clamping cylinder that drives the clamping yoke in an axial direction toward the boring location, from an open starting position into a clamping position. The boring device includes a pneumatic boring machine adapted to receive a boring bit, and a boring feed advance drive connected to the boring machine to drive the boring bit in a feed advance direction opposed to and coaxial with the clamping direction of the clamp jaw element. The feed advance drive and the clamping cylinder are operatively coupled or interconnected so that the clamping step and boring step are automatically triggered together in proper sequence. The apparatus is especially suited for automatically clamping together two workpieces and boring holes therethrough, as necessary for forming a riveted connection between the workpieces, particularly in the construction of aircraft components.
