    摘要： An indexable cutting insert (10) for use in a milling cutter (50). The cutting insert (10) having four identical side surfaces (16) extending between generally square shaped top (12) and bottom surfaces (14) with two diametrically opposite protuberances (28) extending away from each other in a top or bottom view of the cutting insert (10). The cutting insert (10) has eight identical major (30) and minor cutting edges (32). The milling cutter (50) having the general form of a circular disk (52) with a plurality of the cutting inserts (10) releasably mounted in insert pockets (54) angularly around the periphery (58) of the cutter. The cutting inserts (10) are arranged to produce a profile (60) on a workpiece (62) having a central straight section (60) and two beveled sections (60', 60'') on either side of the central straight section (60).

    摘要： A machine tool for machining a workpiece (2) comprises a machine base (18), a workpiece holder (14) supported by the machine base for holding a workpiece (2), the holder being rotatable about an axis (15), and a workpiece rotary drive (10, Mw, Ew) for rotating the holder about the axis. A tool mount (16) is supported by the machine base for carrying a tool (4) to be engaged with a workpiece held in the holder, and a drive arrangement is operable to move the workpiece holder and the tool mount relative to each other in a plane which is transverse with respect to the axis. A control arrangement (6) is configured to control the workpiece rotary drive and the drive arrangement so as to machine a surface profile on the workpiece which is non- equidistant from the axis (15) in a plane which is transverse with respect to the axis, such that a tool (4) mounted in the mount is engaged with the workpiece (2) to commence the machining operation whilst the workpiece is being rotated by the workpiece drive. A method of machining a workpiece is also provided.

    摘要： High precision machining is enabled by eliminating the need for a conventional swiveling table, and by enhancing rigidity for supporting a work by relatively reducing the distance from the upper surface of a stationary body section (1) to the position for machining a work by means of a tool on a rotary spindle (17). A pair of guide tracks (28a, 28b) respectively passing two positions separated in the X axis direction of the stationary body section (1) and in the Z direction intersecting the X axis direction perpendicularly are allowed to guide feed tables (30a, 30b) to be movable independently. A support/feed/turn output member (25) is latched to bridge the feed tables (30a, 30b) on the guide tracks (28a, 28b), one feed table (30a) and the support/feed/turn output member (25) are coupled to rotate relatively about a line in the Y axis direction which intersects perpendicularly both the X axis direction and the Z axis direction, the other feed table (30b) and the support/feed/turn output member (25) are coupled to rotate relatively about a line in the Y axis direction and to displace relatively in a specific direction related to the positions of the both feed tables (30a, 30b), and a means (35) for regulating relative displacement in the specific direction is provided additionally.
