Technology for milling selected portions of a workpiece by a cutting tool of a numerical control machine is described. The described technology provides methods and apparatuses for milling areas of a part so that more aggressive machining parameters can be used in the toolpath, thereby resulting in reduced machining time and load. The described technology additionally determines directions of the tool axis vector at points along a toolpath in order to achieve a desired part shape while optionally maintaining high material removal rates.

The whirling device comprises a retaining ring extending around a ring axis and a central opening and having at least one receiving area for a machining element for machining rod-shaped material in the area of the central opening. A coolant supply comprises a supply sleeve which is arranged on the retaining ring via a rotary bearing and comprises a coolant connection and a supply area adjoining a connection area of the retaining ring. Starting from at least one inlet opening in the connection area of the retaining ring, at least one passage leads through the retaining ring to at least one outlet opening which faces the central opening of the retaining ring and is designed for a machining element in a receiving area. No space is required for the coolant supply between the retaining ring and an assigned lathe.

This machine tool has: a main shaft having a tool mounted on the tip thereof; a main shaft head that rotatably supports the main shaft; orthogonal triaxial linear feed shafts that move the main shaft and a table relative to one another; and a rotational feed shaft that is capable of changing the orientation of the rotational axis of the main shaft. The machine tool is provided with: a rotational feed shaft device that is not parallel to any of the linear feed shafts and that rotates the main shaft head around an inclined axis that intersects the rotational axis of the main shaft; and a main shaft head base that rotatably supports the main shaft head so that the point of intersection between the rotational axis and the inclined axis of the main shaft coincides with a defined reference point at the tip side of the main shaft.

A tool spindle for machine tool includes a tool spindle having a front end in which a tool is mounted and installed to be rotatable, and a vibration damping device mounted in a rear end of the tool spindle to damp cutting vibration generated at the front end of the tool spindle, and including a rigid member coupled to the rear end of the tool spindle and a tuned mass member elastically supported by the rigid member.

An electrical tool including: a cutter bit assembly, a driving mechanism for providing a power to the cutter bit assembly, and a flexible transmission mechanism, which is connected at one end thereof to the driving mechanism and connected at the other end thereof to the cutter bit assembly; the flexible transmission mechanism is twistable and bendable, and is configured to transmit the power provided by the driving mechanism to the cutter bit assembly.

The present invention discloses an overhead machining device based on a portable 5-DOF full parallel module. The overhead machining device based on a portable 5-DOF full parallel module comprises: a sliding table for moving a parallel module to increase the stroke of the machine tool such that the machine tool can machine large components and can also simultaneously conduct the mounting and the machining of workpieces at different stations; a CNC rotary table; and a portable 5-DOF full parallel module. The portable parallel module has a large swing angle range, can conduct the conversion between vertical and horizontal machining modes and can achieve five-face machining in one setup in cooperation with the CNC rotary table. The parallel module can move flexibly, and can machine large and complex components after mounted on the sliding table.
