Abstract: A milling tool includes a main body and a plurality of cutting inserts with respective cutting edges. The main body has an end face and a barrel-shaped curved lateral face. A first group of the plurality of cutting inserts are fastened on the end face, a second group of the plurality of cutting inserts are fastened on the barrel-shaped curved lateral face, and the respective cutting edges describe a barrel shape. Each one of the plurality of cutting inserts may be designed as an indexable insert.

Abstract: A device for machining rolling element pockets in a workpiece includes a workpiece support, a main spindle, a clamping means fastened to the main spindle, a pressure cylinder and a machining tool. The clamping means includes a receiving arrangement for fastening the clamping means to the main spindle and a pressure plate for pressing the workpiece on the workpiece support. The pressure plate has a passage opening. The pressure cylinder connects the receiving arrangement to the pressure plate. The pressure cylinder is arranged to provide a force to adjust a contact pressure of the pressure plate on the workpiece. The machining tool is fastened to the main spindle and guidable through the passage opening to machine the workpiece.

Abstract: Techniques for melt spinning and cooling of multifilament polyamide threads are described. The process involves multiple filament bundles spun alongside one another and cooled down separately by streams of cooling air flowing radially from the outside to the inside. Streams of cooling air are produced from a blowing chamber connected to a pressure source. Exhaust gases that occur during the spinning are removed through exhaust openings before the cooling of the filament bundles. An air pressure is set within the blowing chamber in such a way that the exhaust gases in the vicinity of the filament bundles are blown out through the exhaust openings from the inside outwards. A blowing box is assigned a pressure setting means for setting an air pressure within the blowing chamber, by which an air pressure for blowing out the exhaust gases can be set at the exhaust openings of a connection adapter.

Abstract: A texturing machine is described comprising a plurality of processing points for texturing a plurality of multifilament threads. The texturing machine comprises a plurality of delivery mechanisms per processing point and a texturing system for guiding, drawing and texturing one of the threads. A central heating device is associated with the processing points for thermal treatment of a plurality of threads, wherein the texturing systems within the processing points downstream of the heating device each delimit a texturing distance. In order to treat all threads qualitatively the same, according to the invention the texturing systems of the processing points associated with a thread outlet of the heating device are held in a symmetrical arrangement with respect to the heating device such that the threads within the processing points can be guided in texturing distances of the same length.
