The present disclosure is directed toward a tooling assembly for a machine having an automatic tool changing system. The tooling assembly includes a holder, a tool body, and an internal passage defined within and extending through the holder and the tool body. The holder includes a machine interface configured to engage with a spindle of the machine. The internal passage is operable to have a coolant fluid flow within, and has a stem channel and a curved channel extending from the stem channel.

A boring head (10) having a movement transmission mechanism for selectively moving a cutting insert (20) a desired amount. The movement transmission mechanism includes a rotatable member selectively radially displacing the cutting insert the desired amount in a first direction and a primary member selectively radially displacing a balancing mass (50) in a second direction opposite the first direction while also axially displacing the balancing mass. The displacement of the balancing mass in the second direction effectively counters the displacement of the cutting insert in the first direction such that rotational balance of the boring head is automatically maintained.

The burnishing part includes: a mandrel; burnishing rollers; a frame; an adjustment member that presses the frame axially from one end thereof to adjust the axial position of the frame with respect to the mandrel; and an elastic member that is arranged axially on the other side of the frame to support the frame. The reaming part includes: a base part that is detachably attached to the mandrel; and machining blades that are formed integrally with the base part. This results in providing a combined machining tool that is capable of machining an inner peripheral surface of a workpiece having a smaller diameter, and a machining method using the same.

The present invention provides a rigid modular holding with axial and radial compensation for multiple and universal application of all machining processes, engineering, machine building, and construction fields where ever applicable for rotary and static systems. Design of modular holding includes male and female portions (401,301) of joining parts machined to the required shape and clearances to accommodate modular locking rigidly with face butting (407, 308). Radial and axial run out adjustments is controlled by the grub screws (307, 306) and run out compensation can be achieved within micron. An Area used for clamping and designed within the area of joining parts results reduction in material and processing cost. Since, the material is not protruding out from the surface of the joining parts, esthetically looks good and convenient for designing multiple applications as it is not possible at present.

A machining tool for deburring boreholes, which lead laterally into a recess, comprising: a shaft; a cutting head with at least one circumferential cutting blade associated with a chip groove and having a cutting edge extending, at least in sections, in an axial direction, and which can perform a cutting process by virtue of relative movement between the tool and a workpiece, and which lies on a virtual cylindrical rotation surface; and at least one cutting-blade-free and chip-groove-free surface area; at least one fluid channel closed on the cutting head side, extending through the shaft into the cutting head; and at least one branch channel with an outlet opening. The outlet opening is in a dynamic pressure active surface radially set back relative to the virtual rotation surface, and is larger than a flow cross-sectional area of the at least one branch channel at the outlet opening.

A handheld machining device (1), particularly for drilling, having a mechanism includes: a first mounting (20), on which a tool holder (2), and a motor (3, 4) arranged to rotate the tool holder (2), are mounted; a second mounting (30); and an element (40) for translatably guiding, between the first mounting (20) and the second mounting (30), a linear actuator (5) enabling the first mounting (20) to be spaced apart from the second mounting (30), and the first mounting (20) to be brought toward the second mounting (30). The motor (3, 4) is electric, and the rotor (4) of the first motor (3, 4) is directly mounted onto the tool holder (2) and is rigidly connected thereto.

The present invention concerns a sealing system for a tool holder of a fluid-assisted axial machining or milling machine, including:—at least first and second seals contributing to define a space for the flow of fluid to at least one inner channel of the tool, one of the seals being applied to the tool or an optional adapter carrying the tool and the other seal a) being applied to the tool or to the adapter carrying the tool or b) being applied to a surface spaced apart from the tool and rotating with same, with 0.3≦Do/Dj.sub.max for Do in the interval [1; 3] in mm and 0.5≦Do/Djmax for Do in the interval [3; 20] in mm, where Do is the diameter of the tool facing this other seal and Djmax is the internal diameter of this seal.

A method of machining a workpiece is provided that is capable of forming a fresh air inlet in an arbitrary position in an outer shell of a container. According to the present invention, a method of machining a workpiece is provided that includes: machining to form a round hole in a workpiece using a boring drill having a tubular end portion, the end portion provided with a flat surface and a notch, and having a blade on a side of the notch, by pressing the flat surface against the workpiece while rotating the drill to contact the blade with the workpiece.

The present disclosure is directed toward a tooling assembly for a machine having an automatic tool changing system. The tooling assembly includes a holder, a tool body, and an internal passage defined within and extending through the holder and the tool body. The holder includes a machine interface configured to engage with a spindle of the machine. The internal passage is operable to have a coolant fluid flow within, and has a stem channel and a curved channel extending from the stem channel.

A method of priming a minimum quantity lubrication (MQL) tool includes determining a category of the tool, supplying a short-prime MQL dosage if the tool is a first category or if both a second category and lubricated within a first predetermined timeframe, and supplying a long-prime MQL dosage if the tool is the second category and has not been lubricated within the predetermined timeframe. The category is based on internal passage complexity of the tool.
