There is provided a undercutting boring tool (10) comprising a bar body (11). A lost motion link consists of a spring (26) selectively compressed by a lost motion rod (27) having a lost motion slot (33) spaced from a drive pin (34). An operating rod portion (36) has a trunnion body (37) at its front end having a pin (41) adapted to engage the lost motion slot (33). A tool carrier (42) forms a pair of spaced flat tines (43) and forms a bearing surface (44) in the bight. The upper tine (43) and the bearing surface (44) section are slotted at (45) to allow the passage of a control link (46). Apertures (47) in the tines (43) engage pins (50) on the trunnion body (37). The bar of a generally H-shaped tool assembly (52) comprises a bearing surface (53) running in the bearing surface (44). A crank portion (54) is connected to the control link (46) via crank pin (55). Drive pins (61) and (62) engage the tool assembly (52) with the end face of the bar body (11) providing positive engagement resisting rotational forces in use. The arrangement allows for post-insertion rotation of the tool assembly (52) from an aligned to a transverse (working) position before engagement of the drive pins (61) and (62).

A cutting head operated by a centrifugal force according to an embodiment of the present invention includes: an external housing that is rotatable; an internal housing installed within the external housing so as to be able to advance and retreat in a diameter direction, advanced toward a cut surface of a workpiece positioned outside the external housing by a centrifugal force according to rotation of the external housing, and retreated in a direction that becomes distant from the cut surface by an elastic member while the centrifugal force disappears; and a cutting tool unit provided in the internal housing and processing a groove in the cut surface while being advanced and retreated by a micro advance and retreat member.

A boring head (1) with an electronic unit (20) integrated in the boring head (1) is provided, the electronic unit (20) comprising a control unit (60), a display (30) and a compartment (26) for a power source (41). The display (30) is connected to the control unit (60) and serves to display information concerning the status of the boring head (1) to a user. The compartment (26) serves to accommodate a power source (41) to supply the control unit (60) and the display (30) with electric power. The electronic unit (20) as a whole is designed as a compact subassembly of the boring head (1).

A facing head (1) is here described comprising a fixed part (4), couplable with a head of a machine tool (2) via an interface plate (3), a rotary part (5), wherein a compartment (35) is placed internally to which drive means (100) and measurement means (101) are housed for driving and measuring a radial slide (6) which is supported by the rotary part (5) so as to close the compartment (35), and at least one electric collector suitable for transmitting the electrical signals for controlling the drive means (100) and measurement means (101) used for driving and measuring the radial slide (6). The facing head (1) comprises a continuous gasket (40), which is configured in such a way as to completely make contact with the radial slide (6) and is housed inside a respective recess (34) which externally surrounds the compartment (35), and a fluid collector, which is suitable for supplying the compartment (35) with pressurized air, so that the pressure inside the compartment (35) is higher than the atmospheric pressure, so as to seal the compartment (35). The fluid collector comprises a rotary portion (22), which is integral with the rotary part (5) of the facing head (1) and comprises first fluid routes (43) internally thereto, and a fixed portion (23), which is integral with the fixed part (4) of the facing head (1) and comprises, internally thereto, second fixed fluid routes (45) coupled with the first fluid routes (43) to supply the rotary part (5) with a coolant, to supply the compartment (35) with pressurized air, and to transport the oil necessary for automatically locking the radial slide (6).

Machining tool for internal machining of a shaft (2) with an inner bore (3), such as an aircraft engine turbine shaft (fan mid shaft). The machining tool has an external boring bar (6) support device (5), and a boring bar (6) having a diameter smaller than a smallest opening on one side (4) of the inner bore (3) of the shaft (2). The boring bar (6) has a radially extensible cutting insert (7), and an end part (6b) of the boring bar (6) is rotatably connected to a main part (6a) of the boring bar (6). The end part (6b) is provided with one or more radially moveable guiding pads (8).

Provided is a mobile machining system for a turning machining of inner surfaces of hollow-cylindrical components, in particular for machining valve seats. The machining system includes a second drive train and the third drive train in each case which preferably have a gear mechanism, in particular a planetary gear mechanism, which is arranged between the respective motor and the associated gearwheel which projects outward from the rotational part. This leads to a simple, inexpensive and space-saving construction.

An axially and radially compliant deburring tool holds a commercially available end tool holder, which in turn holds a variety of commercially available interchangeable deburring end tools, such as those commercially available for the hand deburring market. The axially and radially compliant deburring tool exhibits axial compliance in response to an external force by allowing a longitudinal sleeve holding the end tool holder to move longitudinally along a longitudinal axis of the tool, against a bias force. The axially and radially compliant deburring tool exhibits radial compliance in response to an external force by interaction between a cam contact member and a concave cam surface, both under the bias force and hence operative to return the commercially available to a centered, extended position in the absence of external forces.

Disclosed is a device for removing tool joint edge burrs from a cap opening of a wheel. The cap opening of the wheel is an opening configured to mount a decorative cap of the wheel. The tool joint edge burrs are formed inside the cap opening of the wheel during machining the wheel and are a circular edge inside the cap opening. The device includes a cutter system which is configured to remove the tool joint edge burrs from the cap opening of the wheel by a first cutting edge and a second cutting edge of the cutter system.
