摘要： The invention relates to a method for machining flat surfaces (30) of a workpiece (32) using a tool (10), in particular a milling tool, which is moved in a collision-free and laterally inclined manner (α) relative to a flat surface (30) such that a contact point (34) is guided on the flat surface (30). The flat surface (30) is machined using a tool (10) with a cutting contour (18), which has a conically convex design, on one flank (16) of the tool (10) at a pivot angle (ß) parallel to the flat surface (30) in order to prevent a one-sided collision completely by the tool (10) and at at least two different pivot angles (ß, ß') parallel to the flat surface (30) in order to prevent a two-sided collision by the tool (10), wherein the flat surface (30) is separated into at least two machining segments (44, 44', 44''), each of which is assigned an individual pivot angle (ß, ß') of the tool (10) in order to prevent a two-sided collision.

摘要： The milling tool (1) has a spindle (2, 3), which is mounted in a housing (8) and carries a milling head (14) fitted with cutting inserts (15). Arranged in the drive train of the milling head (14) is a torque-transmitting resilient coupling (13). The spindle (2, 3) actually comprises spindle parts (2, 3) that are connected by a plug-in connection via a bearing bush (9, 10) and can be turned with respect to each other, and the coupling (13) is arranged between these spindle parts. The resilient coupling comprises a helical spring (13) that is fastened by each of its ends to a spindle part (2, 3). The milling head (14) is fitted with sharp-edged cutting inserts (15), which have a wedge angle of 40 - 75° and have on the milling head (14) a position in which they operate with a positive rake angle of at least 6° and a clearance angle of at least 6°.

摘要： The invention relates to a milling head for milling chamfers, especially for a mobile chamfer miller, comprising successive seats for blanking dies, said seats having a position in which the blanking dies with a leading edge angle of between 40 and 75° operate respectively on average with a positive effective cutting angle of at least 6° and a clearance angle of at least 6°, and are provided for a border comprising blanking dies with a staggered arrangement of the cutting edges, such that respectively only one cutting edge length of 15 mm, preferably 12 mm, at the most, is active. Said measures increase the cutting performance of the milling head. The reduced cutting edge length can be formed on a long blanking die instead of using a shorter blanking die, in such a way that the cutting edge is interrupted by cavities or other e.g. flat triangular recesses on the surface of the blanking die. The staggered arrangement is then comparatively small.

摘要： The invention relates to a lathe tool (10) for machining workpieces, said tool comprising a base body (12) having a clamping section (14) and a tool head (16) which comprises a cutting region (18) having at least one cutting edge (20), wherein the tool head (16) comprises at least one coolant channel (22) for supplying a cooling and/or lubricating fluid into the cutting region (18). According to the invention, at least some sections of the coolant channel (22) have a cross-section (24) that tapers in the direction of the tool head (16), and in this region, at least two coolant outlet lines (30, 38) that branch off from contact points (40, 42) of the coolant channel (22) in the direction of the tool head upper surface (44) are arranged in the region of the tool head (16), wherein the at least two coolant outlet lines (30, 38) are arranged at positions (40) that are offset in the axial longitudinal direction of the coolant channel (22). The invention also relates to a production method for a claimed lathe (10), in which method the blank of the lathe (10) is produced by means of a sintering method in which the coolant channel (22) of the lathe (10) is formed integrally in the sintering method at the same time.
