Abstract: A machine tool (20) for machining a gearwheel workpiece (1), having: a tool spindle (21) for fastening a tool (2), a workpiece spindle (22) for fastening the gearwheel workpiece (1), a CNC controller (50) and multiple axes for the CNC-controlled machining of the gearwheel workpiece (1) using the tool (2), an optical detector (40) to acquire image information (BI) of the gearwheel workpiece (1), and a module (51), which is designed to ascertain characteristic actual parameters of the gearwheel workpiece (1) based on the image information (BI) of the gearwheel workpiece (1).

Abstract: A device having at least two grippers (102) for the form-fitting gripping of a bevel gear (1) having a cone face, a heel region, and an axis of rotation (RA). The at least two grippers (102) can be infed radially in relation to the axis of rotation (RA), and each of the grippers (102) has at least one inner region (104) for interacting with the cone face, and a counter holder (103) for interacting with the heel region. Each gripper (102) can have a holder (101) having a changeable angle of attack on an inner region (104) of the holder, and the holder (101) can be movably mounted on the gripper (102) so that it adapts its effective angle of attack in relation to the inclination of the cone face of the bevel gear (1) during radial infeed in the direction of the bevel gear (1).

Abstract: Cutter head for accommodating multiple cutters, wherein the cutter head has a separate receptacle opening for each of the cutters, and wherein the cutter head includes clamping means for clamping the cutters in the receptacle openings. A cavity is implemented in the cutter head in the region of at least one of the receptacle openings, which is separated by a thin wall or layer from this receptacle opening, and the cavity can be filled with a fluid and a pressure can be applied thereto.

Abstract: A takeup machine for continuously advancing yarns (1) comprises a spindle revolver (5) mounting two winding spindles (6, 7), which alternate in winding packages (10). The packages are doffed by a servicing automat (doffer) in two positions of the spindle revolver (5) which is moved on step-by-step as the package increases in size on the operating spindle (6). The two positions for removing the full package or packages and for slipping an empty tube or tubes (8, 9) on the previously emptied idle spindle (7) may be located at any desired points within a doffing range (41), since the package mandrels of the servicing automat are caused to follow the idle spindle (7) by suitable sensors.
