A rapid change chuck adapter system includes a chuck adapter that is removably attachable to the chuck in place of removed chuck teeth. The chuck adapter is operable to engage a collet such that an operation of the chuck as if the chuck teeth were not removed operates the collet via the chuck adapter.

An automated tool clamping device, in particular a fully automated tool clamping device is configured for a clamping-in of at least one tool in a tool chuck by a tightening of a union nut of the tool chuck and/or for a declamping of the tool out of the tool chuck by a release of the union nut, and comprises a clamp element, which is at least configured to generate a connection, in particular a clamp connection, with the union nut of the tool chuck, and comprises a torque receiving element, which is at least configured to receive at least a large portion of a torque occurring during a tool clamping process, in particular during a tool clamping-in process and/or a tool declamping process.

An ultrasonic machining module that includes an ultrasonic transducer, wherein the ultrasonic transducer is adapted to receive a machining tool and a vibration-isolating housing adapted to be both compatible with a machining system and to receive the ultrasonic transducer therein, wherein the housing further includes at least one modification for isolating all vibrations generated by the ultrasonic transducer when the device is in operation except axial vibrations transmitted to the machining tool, thereby preventing unwanted vibrations from traveling backward or upward into the machining system. The ultrasonic machining module may also include an acoustically tuned collet and/or an acoustically tuned system for delivering coolant fluid through the module to a machining tool or target substrate.

A router includes a motor assembly that is arranged and configured to hold a router tool and to impart rotation to the router tool and a frame that is fixed in size and that is configured to house the motor assembly.

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 fixation device for fixing a first part of a surgical instrument to a second part of the surgical instrument. The fixation device has a longitudinal axis and includes a fixation body configured to accommodate a portion of the first instrument part and a portion of the second instrument part therein. A first fastening member and at least one movable first clamping member are configured to clampingly engage at least the first instrument part so as to fix at least the first instrument part to the fixation device. A first actuation member is configured to receive at least a portion of the fixation body. The first actuation member includes a second fastening member configured to engage with the first fastening member. The first actuation member is configured to exert a clamping force on the first clamping member when the second fastening member is in engagement with the first fastening member.

An adjustable collet holder for use with a lathe is provided. The adjustable collet holder may include a set of hold down screws to hold it in place once adjusted. Adjustment may be achieved by adjusting multiple set screws to change both angular and concentricity orientations of a collet receiver relative to a body of the collet holder.

A chucking apparatus for chucking an object contains a basic body which has a receiving space in which the object can be disposed. A chucking device is provided with a chucking nut which is screwable onto the basic body and by the chucking nut being screwed onto the basic body the object disposed in the receiving space can be chucked non-rotatably. The chucking nut has a plurality of roller bodies having a defined roller engagement structure. The roller bodies are held in an axially rotatable manner on a chucking body of the chucking nut and are arranged distributed in the circumferential direction on the chucking nut. The rollers by their roller engagement structure are in engagement with the basic body engagement structure of the basic body.

A chuck including a chuck body that supports a plurality of jaws. An outer sleeve is axially fixed with respect to the chuck body. A nut is coupled to the outer sleeve, and the nut is movable axially and radially relative to the chuck body. The nut interacts with the jaws such that when the outer sleeve rotates, the nut moves axially and radially relative to the body.
