Abstract: A twist drill or drill/chamfer tool that comprises a drill (1) with a shaft section (2) that is provided with a twisted flute, and a clamping ring (4) as the retainer of a facing cutter (5). Said clamping ring tubularly encloses the shaft section (2) or the drill shaft (30) and can be fixed thereon in different axial adjustable positions. The clamping ring (4) can be tensioned on the drill (1) by means of tension screws (6) that extend therethrough substantially radially to the axis (7) of the drill. The tension screws (6) impinge the surfaces of the twisted flutes (9, 10) which are enclosed by the clamping ring (4) indirectly with a clamping shoe (19, 20) that is interposed in a twisted flute (9, 10).

Abstract: The invention relates to a chip removing tool comprising a tool shank which acts as a support for a perforated plate. The perforated plate is tensed by means of a screw connection passing through the orifice of the perforated plate and a through hole of the tool shank, containing a screw which is introduced from the side of the perforated plate, and a corresponding nut positioned beneath the tool shank inside the seat of the tool shank. The tensed perforated plate is adjusted in an effective manner in a direction of adjustment which is substantially radial in relation to the axis of rotation of the tool shank, whereby the contact surfaces between a) the screw head and the perforated plate and b) the head of the corresponding nut and the tool shank enable a pivotable movement of the screw connection following on from the adjustment movement, said screw connection consisting of a screw and a corresponding nut, as a result of crowning.

Abstract: A side milling cutter with cutting inserts, by which side milling cutter a crank pin can be cut with a single feed motion. The plate-shaped cutting inserts are arranged on the periphery of the side milling cutter alternating between the left and right side in a peripheral direction, and are oriented essentially radially with their cover surfaces in relation to the cutter axis, which cover surfaces contain the tool faces. The cutting inserts are also arranged so as to form a gap on the periphery of the cutter which is so narrow that the length of the arc of action between the point of entry and the point of exit of cutting is greater than the half of the gap of the arrangement of cutting inserts on the periphery of the cutter. The present invention also relates to the configuration of the cutting inserts as indexable inserts which can be used on the left and on the right.

Abstract: In addition to having a stop member in the form of a hollow cylinder which is slotted and can be spread by means of an adjustment screw, an adjustable stop for a cutter adjustably arranged in a main casting or body of a tool is also provided with a sleeve member which can be inserted into a longitudinal bore of the stop member. The sleeve member has inside threads which can be brought into engagement with the adjustment screw. This results in an improvement of the load carrying capacity of the threaded connection. Since the sleeve member can move in the adjustment direction, the bending load on the adjustment screw is reduced.

Abstract: A rotary tool for drilling and chamfering, which takes place in one common advance, essentially comprises a base body, a drill clamped centered therein and a chamfering tool disposed on the end of the base body toward the drill tip and having a cutter body tip disposed next to the flank of the lateral free face of the drill. The chamfering tool can be radially adjusted in relation to the drill in a direction pointing at right angles in respect to the drill axis.

Abstract: A drill with a drill point part that contains the drill cutter and is made of a solid hard material. The drill point part is replacably attached to the end face of a drill shaft. The drill shaft is penetrated by a shaft groove which extends in an axial direction of the shaft to accomodate the drill point part and can center the drill point part in the groove region. The drill shaft has grooves on its periphery which run in the axial direction and extend into the region of the shaft groove and continue into the region of the drill point part. The drill point part can be clamped on its side faces corresponding to and opposite the groove flanks in a force-locking manner by an insertion-clamping fit in the shaft groove.

Abstract: A process and machine for the preparation of pile ware uses a single needle bedded warp knitting machine, having pile sinkers. During the swing-through of the guides subsequent to the underlap into the overlap position, first the ground threads and then the left pile threads, are laid to the rear of the needles, and run along these, with separation from each other. The pile sinkers are introduced into the space between the ground threads and the left pile threads, during or after the swing-through, and stay there until the knock-over of the stitch. The threads are provided to the guide bars in a one full/one empty order, only every second needle serving for stitch formation. The number of pile sinkers equals half of the number of needles. Right pile threads are provided which are overreached by the pile sinkers together with the ground threads laid about needles not serving for stitch formation and are then knocked over.

Abstract: A milling cutter is provided with a base body that can be driven in a rotating manner around its longitudinal axis.
