In the case of a method for chip-removing machining of workpieces (14), in particular for making bores in workpieces (14), wherein a tool (18) is put into rotation (20) relative to the workpiece (14) and the tool (18) is moved relative to the workpiece (14) with a feed motion, the tool (18) executes an oscillating motion in the direction (z) of the feed motion relative to the workpiece (14), a settable oscillation component being imparted to the feed motion through control means.

The invention relates to a collector for bore cuttings that are produced when a bore hole is drilled in the ground. Said collector comprises a housing having a face that can be oriented towards the ground and a back wall spaced apart therefrom. The face and the back wall have housing openings that are aligned in relation to each other, whereby a drill can extend through these openings. The housing encloses a cleaning device which cleans the drill when it is withdrawn from the housing, and a dirt collection chamber. The aim of the invention is to improve the collector for bore cuttings in such a manner that bore cuttings that are produced when a bore hole is drilled are reliably collected and no bore cuttings can escape when the drill is withdrawn from the housing. For this purpose, the cleaning device is adapted to clean the rotating drill during drilling.

The invention concerns a perforating device comprising a cutting tool (10), means for rotating (11) the cutting tool (10) and means for translating (12, 14) the cutting tool (10), the ratio between the rotational speed and the translational speed being variable during rotation of the cutting tool (10). It comprises a gear train (16, 17; 18, 19) for synchronizing the rotating means (11) with the translating means (12, 14). The speed ratio between a driving pinion (16; 18) of the gear train, rotationally linked to the means (11) for rotating the cutting tool (10) and a transmission pinion (17; 19) of the translating means is reversed at least once during one rotation of the cutting tool (10). The invention is useful for fragmenting the resulting shavings.

In order to rivet a light alloy added reinforcement rib (13) on a shell structure made of composite material (11), an external working head (21) is brought near to the external side of the wall of the shell structure (11), until a predetermined thrust is applied; an internal working head (45) is brought near to the internal side of the wall of the shell structure (11), until the load detector of the external (21) detects a predetermined variation of the thrust applied to the shell structure by the external working head (21); with the external working head (21) a thrust is applied to the external side of the shell structure (11), equal to a predetermined compression force, necessary for drilling. This allows the shell structure (11) be drilled with a cheaper apparatus, since only one of the two drilling robots (38, 45) used is provided with pressure sensors.

Object: A drill dust collector is provided that is capable of drilling holes in an area ranging from a position near a corner to a position distant from the corner and that can be positioned with a side face in contact with an upright face such as a wall during drilling. Means for Solving: The drill dust collector has (i) an opening 2C provided in the upper face of a box having an open lower face 1C, for receiving a drill inserted therein; (ii) a suction port 1 U connected to the leading end of a suction hose 3 connected to an suction apparatus; and (iii) a contact member 1 A of high flexibility formed so as to extend around the lower face of the box. The box has a lid member 3 composed of the opening 2C and its peripheral part, and a box body 1. The lid member 3 is placed so as to be rotatable relative to the box body 1 and the opening 2C is located at a position the center of which is shifted from the center of rotation of the lid member 3 relative to the box body 1.

Eine Staubabsaughaube (1) für einen längs einer Drehachse (A) angetriebenen Dosensenker (2) zum Einbringen eines kreiszylinderförmigen Lochs (3) in eine Wandung (4) mit einem beidseitig stirnseitig zumindest teilweise offenen Haubenmantel (5) mit einer Stirnansetzkante (16) und einem in deren Längsdrittel angeordneten Absaugstutzen (6), dadurch gekennzeichnet, dass am Innenmantel (7) des Haubenmantels (5) zumindest zwei umfänglich versetzte Axialführungsmittel angeordnet sind, in welche jeweils zugeordnete Gleitmittel axial versetzbar geführt eingreifen, die mit einem sich radial zur Drehachse (A) erstreckenden, den Haubenmantel (5) zumindest teilweise abdichtenden Dichtschild (12) verbunden sind, der über ein konzentrisch angeordnetes Lagermittel drehfrei sowie axial fest mit einem Antriebsflansch (14) des Dosensenkers (2) verbindbar ist.
摘要:
A chip breaker drill bushing assembly (11) for a fluted drill bit (37) is disclosed. The assembly comprises a drill bushing housing (13) and a sleeve (15). The drill bushing housing (13) includes a body (17) and an outwardly protruding guide shaft (19). The guide shaft has a smooth end (31) for tightly contacting the surface of a work piece (63) to be drilled. The sleeve (15) is located in the body (17) of the housing (13), in alignment with the guide shaft. The end of the sleeve (15) facing the tip (29) of the guide shaft (19) includes a chip breaker (41). The chip breaker (41) includes two spaced-apart teeth (46a, 46b) that are defined by two helical troughs (47a, 47b) that protrude into the sleeve (15). The two helical troughs (47a, 47b) are aligned with two longitudinal apertures (33) in the outwardly protruding guide shaft (19).
摘要:
In a system which interrupts the infeed signal generated by a CNC (1) machine drive signals are applied to at least an RPM Control Electronics Module (3) to drive the rotation of a cutting tool (10) and the infeed drive motor electronics (7). The frequency is user selectable and the frequency used to eliminate or minimize chip formation is dependent upon the material being drilled, the infeed rate, the RPM of the tool (10), and the diameter and point geometry of the tool (10) so adjustment by the machine operator is required. The interrupted or chopped signal causes the downward motion of the RPM motor (5) to be interrupted in conformance with the frequency generated to cut forming spiral chips.
