Abstract: A tool for chip removing machining, including a basic body and a cutting insert detachably connected to the basic body via an interface. The interface includes a first connecting surface formed in the basic body in which a chute is formed that has two side-flank surfaces diverging from a bottom. The interface also includes a second connecting surface formed in the cutting insert in which there are formed a number of male members having converging side-flank surfaces that abut against the side-flank surfaces of the chute, and at least one transverse shoulder surface that abuts against a transverse stop surface in the connecting surface of the basic body.

Abstract: A tool for chip-removing machining includes a holder on which in indexible cutting insert is mounted. The holder includes a first base surface on which a plurality of male parts are disposed to define an insert seat. The insert includes generally parallel second and third base surfaces, each having a plurality of female parts disposed therein. The insert is invertible such that the female parts of one of the second and third base surfaces receive respective male parts of the holder. A fastener secures the insert on the seat, with the male parts tightly fitted in the female parts. The male parts are flexible relative to the first base surface to ensure a firm abutment of the male parts with surfaces of respective female parts.

Abstract: A high bandwidth rotary fast tool servo provides tool motion in a direction nominally parallel to the surface-normal of a workpiece at the point of contact between the cutting tool and workpiece. Three or more flexure blades having all ends fixed are used to form an axis of rotation for a swing arm that carries a cutting tool at a set radius from the axis of rotation. An actuator rotates a swing arm assembly such that a cutting tool is moved in and away from the lathe-mounted, rotating workpiece in a rapid and controlled manner in order to machine the workpiece. One or more position sensors provides rotation and position information for a swing arm to a control system. A control system commands and coordinates motion of the fast tool servo with the motion of a spindle, rotating table, cross-feed slide, and in-feed slide of a precision lathe.

Abstract: A tool for chip removing machining, including a replaceable cutting insert and a basic body. The basic body includes a rear fixing part, a front supporting part having an insert seat, and a tightening part situated over the support part, and spaced-apart from the front supporting part by a first gap and from the rear fixing part by a second gap. The tightening part is connected to the basic body via a joint. The joint is formed of at least one elastically resilient material portion and has an axis around which the tightening part is pivoted in order to press the cutting insert against the insert seat by a front finger. The rear fixing part includes an internal channel for feed of a fluid in the forward direction through the basic body. The internal channel extends into a second channel inside the tightening part via a channel section that is entirely or partly housed in a bridge which, like the joint, is formed of the material in the basic body, and which bridges one of the first and second gaps.

Abstract: A machine tool assembly includes a high speed rotating spindle for forming extremely precise surface contours on a work piece. The spindle is supported on a spherical air bearing about its center of gravity. The spindle can be rotated through an air turbine drive system incorporated into the spherical air bearing to eliminate any undesirable moments about an axis perpendicular to the long spindle axis. The spindle is adjustable in pitch and yaw directions through the influence of X-Y actuators. The X-Y actuation system is preferably electromagnetic and provides a non-contact method of displacing the spindle shaft in a controlled manner at any speed.

Abstract: A dynamic spindle adjustment permitting an adjustment movement for the compensation of a wobble of the body held by the work spindle is provided on the spindle bearing of a machine tool. The regulation is designed at least dynamically enough for the regulation to permit a reliable tracking of the rotating work spindle. As a result of this, one or more spindles can be moved relative to a stationary machine in such a manner that the path of a body held on the work spindle represents an ideal rotation about the desired body axis, that is, the axis of symmetry. The compensation motion can be achieved by energizing appropriate actuators of the bearing devices with sinusoidal and cosinusoidal adjustment signals, which are superimposed to produce a circular motion of the affected bearing device. This circular motion compensates for orbital motions of the misaligned body (7) held on the work spindle.

Abstract: A face-milling insert, including a chip-removing main cutting edge adjacent to a first clearance surface, and a surface-wiping secondary edge adjacent to a second clearance surface, the main cutting edge forming an angle of 45° with an imaginary straight line in the extension of the secondary edge. Adjacent to a third clearance surface, an intermediate cutting edge is formed between the main cutting edge and the secondary edge, the intermediate cutting edge being shorter than the main cutting edge and forming an angle within a range of 20-40° with the extension line. The intermediate cutting edge transforms into the adjacent edges via arched part edges adjacent to convex clearance surfaces.
