摘要： The invention relates to pin bosses (1) of a piston (2) for an internal combustion engine, each comprising a pin bore (3) for supporting a piston pin (14). In order to reduce the tangential stresses in the zenith area of the pin bores and thus to extend the service life of the piston, the inner areas (16) of the pin bores (3) as viewed in the direction of the bore axis (13) have areas on both sides of the zenith (4) that have a greater distance from the bore axis (13) than the zenith (4) of the pin bore (3), and the outer areas (17) of the pin bores (3) as viewed in the direction of the bore axis (13) are transversely oval relative to the piston axis (7).

摘要： The invention relates to a tool spindle (1) for an elongate drilling tool (2) having an end-side clamping shank (3) for clamping the drilling tool (2) and a centring depression (4), arranged opposite the clamping shank (3) in the longitudinal direction, for centring the drilling tool (2), wherein the tool spindle (1) comprises a drive shaft (5) for driving the drilling tool (2), a chuck (7) for receiving the clamping shank (3), said chuck (7) being rigidly connected to the drive shaft (5) along a rotation axis (6) directed longitudinally with respect to the drive shaft (5), and at least one radial bearing (8, 9), which radially surrounds the drive shaft (5) at least regionally, for radially supporting the drive shaft (5), said tool spindle (1) being configured in such a way that the radial bearing (8, 9) supports the drive shaft (5) so as to be rotatable about the rotation axis (6). Improved stabilization results when the radial bearing (8, 9) is an active magnetic bearing and is configured such that it furthermore supports the drive shaft (5) in a pivotable manner about at least one pivot axis that extends perpendicularly to the rotation axis (6) through a fixed point (10), wherein the fixed point (10) is located in the centring depression (4) when the drilling tool (2) is clamped in the tool spindle (1). The invention furthermore relates to a machine tool (15) having such a tool spindle (1).

摘要： The invention relates to a device (1) for machining and assembling a piston of an internal combustion engine, that consists of a piston upper part (2) and a piston lower part (3). Said device comprises two work spindles (4, 5) that can be actuated independently from each other and that are arranged in a coaxial manner in relation to each other, whereby one supports the piston upper part (2) and the other the piston lower part (3), two tool carriages (6, 7) that can be actuated independently from each other whereby one tool carriage supports a tool (8) for machining the piston upper part (2) and the other tool carriage supports the other tool (9) for machining the piston lower part (3). Said device (1) is configured in such a manner that both piston parts (2, 3) operate independently from each other, are oriented towards each other and can be assembled together without having to be tightened intermittently.
