A processing tool includes: a body including a cylinder chamber having an opening toward a distal end, and a slide groove extending parallel to the cylinder chamber; a tool received in the cylinder chamber in a detachably attachable manner, and having an anti-rotation groove on an outer periphery; an anti-rotation body disposed in the body and advance to or retract from the cylinder chamber; a pusher disposed in the cylinder chamber in a reciprocable manner, and urges the tool toward the distal end, the pusher including, a pusher body, a retaining body received in the slide groove, and an advance-retract spring disposed on a basal end of the pusher in the cylinder chamber, and urge the pusher toward the distal end.

A cutter holder has a body and a buffering assembly. The body has a specific weight. The buffering assembly is mounted in the body and has a buffering unit and an elastic unit set. The buffering unit has a specific weight that is larger than the specific weight of the body. The buffering unit and the elastic unit set are utilized for absorbing vibration. The elastic unit set has multiple Belleville washers and can be changed in scales or amounts according to practical machining conditions.

A closed-loop machining system that includes a rotating spindle assembly having a body, a tool holder connected to the body, an ultrasonic machining module connected to the tool holder, and a power supply for powering the module; a processor for controlling the operation of the closed-loop machining system; a safety and compatibility bridge linking the ultrasonic machining module to the processor, wherein the safety and compatibility bridge further includes an electrical connection between the ultrasonic machining module and the processor; and at least one microprocessor located in or associated with the ultrasonic machining module for enabling and processing communication between the ultrasonic machining module and the processor.

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 invention relates to tool mount with a base body and a receptacle that is joined with the base body for torque transmission and anchored in the base body in an axially movable manner with a spring preload. The base body exhibits a shank section with a recess that is open on the machine tool side, and a bushing section that axially lengthens the shank section, with a guide borehole that is open on the tool side and separated from the recess of the shank section by a radial dividing wall. The receptacle exhibits a guide section that is guided in the guide borehole of the bushing section in an axially movable manner. The receptacle is anchored by means of an anchor that passes through an axial opening in the radial dividing wall and can be actuated for setting the spring preload via the recess of the base body.

Spring loading insert comprising an insert, spring, and set screw or sleeve and snap ring for retention into a tool holder, which when installed into a tool holder, uses the tool holder tool pocket as the outer shell of the tool, making the tool holder part of the tool itself. By doing this and by having a wide verity of choices of outside diameters for the insert and not only tool pocket diameters but tool connection methods make this a vary versatile and inexpensive way to spring load a tool.

Provided is a detachable tool detachably attached to a tool mounting hole of a tool holder including the tool mounting hole, and a retaining body disposed in the tool mounting hole in a radially inwardly reciprocable manner. The detachable tool includes: a housing supported at a predetermined position of the tool mounting hole, the housing including an elastic body chamber, and a retaining body insertion hole through which the retaining body is inserted; a slider to which a tip tool having a blade at a basal end portion is mountable, the slider supported by the housing to reciprocate inside the tool mounting hole, the slider having a guide groove extending along the tool mounting hole; an elastic body disposed in the elastic body chamber to urge the slider toward a basal end; and an anti-rotation body disposed in the housing to be received in the guide groove.

Disclosed is a tap driver for rigid tapping, which includes adjustable tension and compression of the tap driver. In the preferred embodiment, the tap drive is adjustable by rotation of the outer collar between a plurality of settings, each of which provide a different tension or compression in the tap driver.
