A machine tool includes a workpiece spindle being rotatable about a rotation axis of the workpiece and configured to hold a workpiece such that the workpiece. A tool holding device is rotatable about a tool rotation axis and configured to hold a turning tool via which turning is performed on the workpiece. A movement mechanism is configured to move the tool holding device such that the turning tool rotates relatively to the workpiece toward an arbitrary direction perpendicular to the rotation axis of the workpiece. Control circuitry is configured to execute a machining program, to perform the turning, which includes an additional code which designates a target cutting direction of the arbitrary cutting direction, and to control the movement mechanism to move the turning tool in the target cutting direction with respect to the workpiece while the control circuitry executes the additional code.

The invention relates to a tail stock device (10) for supporting a workpiece in a machine tool, for example a grinding machine. The tail stock device (10) comprises a tail stock arm (16) that is pivotally supported about a pivot axis (S), said tail stock arm having arranged on its outer end (16a) a centering tip (12) that is oriented parallel to the pivot axis (S). By means of a pivot drive (30) comprising a first pneumatic cylinder (31), the tail stock arm 16 can be pivoted between a working position (A) and a resting position (R). The movement of the piston (32) of the first pneumatic cylinder (31) is transmittedvia a first coupling arrangement (35)to the tail stock arm (16). When the tail stock arm (16) is in working position (A), the first coupling arrangement (35) assumes a self-locking position in which a force feedback effect being triggered by a torque that forces the tail stock arm (16) out of working position (A) and into resting position (R) does not or only minimally retroact on the piston (32) of the first pneumatic cylinder (31).

A device for flow-forming workpieces having a rotatable first, outer forming tool for acting upon an outer contour of a first workpiece in the form of a hollow body. The device also has a first, inner forming tool for acting upon an inner contour of the workpiece. The first workpiece can be set in rotation about a first workpiece axis and can be plastically deformed by a pressure applied by the first, inner forming tool and the first, outer forming tool in a forming zone formed between the first forming tools by the material being made to flow between the first forming tools. The device has a drive for driving the first, outer forming tool.

An adjustable lathe mounting system for turning a work piece on a rotating lathe having a lathe bed, headstock, and a headstock spindle, where the work piece is attached to the headstock spindle. The lathe mounting system includes an adjustable base releasably attached to the slotted way of the bed via a locking plate and a pair of laterally adjustable way spacers moveable within a laterally extending slot that engage each side of the slotted way.

In a center-rotation type tailstock, unavailable time due to replacement of parts such as bearings is shortened. A built-in hole is formed in a tailstock spindle. A center rotating mechanism unit is attachable to and detachable from the built-in hole. In the unit, a rotary shaft is supported in a tubular body by bearings. The rotary shaft is made enable a center to be attached. When replacing the parts in the unit attached to the built-in hole, the unit is detached from the built-in hole, and another center rotating mechanism unit incorporating new parts is attached to the built-in hole.

A method for producing a crimp connection includes initially guiding a cable end of a cable with a gripper to a crimping press. For this feed movement the gripper is moved by an actuator in an axial direction along the cable axis. The cable end is thereafter connected with a crimp contact. During the crimping process the gripper is, for compensation for length extension of the cable during crimping, moved along the cable axis in a return movement in an opposite direction to the feed movement.

This present disclosure relates to a device for rotary entrainment of a workpiece clamped between two tips, which is mounted on a machine table of a machine tool, consisting of a base body with a centrically arranged tip and a plurality of concentrically arranged, axially shiftable driver elements which for the rotary entrainment of the workpiece are pressed against or into an end-face surface, wherein an axial position of the driver elements can be defined by active fixation after a centering operation of the workpiece, and to a receptacle opposite the base body, for example a tip or hollow tip, which serves a guidance of an opposite side of the workpiece.
