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 tool holder is provided comprising a base body for coupling with a drive spindle that can be driven rotatingly, whereon a clamping chuck for clamping a tool is provided, further comprising a damping element arranged between the base body and the clamping chuck, wherein the damping element is made of an elastomeric material or of a shape memory alloy, and wherein the clamping chuck is solely connected to the base body by means of the damping element.

A device (100) for capturing, centring, gripping and/or securing an object (140) is disclosed. The device comprises a hub (101) and a ring (102) which are concentric and arranged rotatably relative to each other. On the hub there is at least one first control point (111, 111′, 111″), and on the ring there is at least one second control point (112, 112′, 112″), which control points are arranged at different axial levels (151,152). At least one tensioning member (121,122,123) is arranged to interact with the at least one first control point and with the at least one second control point during the rotation, such that the at least one tensioning member is stretched across the air gap (130) in the device. The different axial levels for the at least one first control point and the at least one second control point mean that the at least one tensioning member can freely pass over the at least one first control point during the rotation and can be stretched across the air gap towards the object. Substantially any desired angle of rotation between the hub and the ring can be obtained in this way.

An inline tool holder including a shaft collar, a mounting plate, a first enclosure, and a second enclosure. The mounting plate is concentrically arranged around the shaft collar and includes a first surface, a second surface, and an attachment mechanism. The first enclosure is removably coupled to the first surface of the mounting plate and the second enclosure is removably coupled to the second surface of the mounting plate. The attachment mechanism of the mounting plate extends radially beyond an outer edge of both the first enclosure and the second enclosure.

A torque transfer assembly for a bit holder includes an axial movement limiting subassembly and a rotation limiting subassembly. The axial movement limiting subassembly is configured to retain a drive body of the bit holder in proximity to a driven body of the bit holder. The rotation limiting subassembly is configured to cause torque applied to the drive body to be transferred to the driven body. The rotation limiting subassembly includes a first cam body at a distal end of the drive body and a second cam body at a distal end of the driven body. The first and second cam bodies are configured to transfer a majority of the torque between the drive body and the driven body indirectly via the torque transfer assembly by limiting rotation of the first cam body relative to the second cam body.

The present disclosure provides a deburring apparatus and a deburring method that does not require a positioning engagement part that is engaged with a fixed part of a machine tool. The deburring apparatus (10) includes a housing (1) with a shank (11), a transmission rod (3), a recovery rod (5), a tilting shaft (4), a spring (6), a holder (7), and a rotary-to-rectilinear motion conversion mechanism (9) with a plunger (8). The spring forces the recovery rod toward the tilting shaft. The holder for fixing the cutter (101) is arranged on the tilting shaft in a manner rotatable through a predetermined rotation angle. The rotary-to-rectilinear motion conversion mechanism separates the first flange portion from the second flange portion and brings the plunger into contact with the recovery rod on the tilting axis (43) when the holder rotates in a direction opposite to the rotation direction of the shank (11).

A chamfering tool 10 includes: a movable flange 5 having a cylindrical shape so that one end portion of a joint member 4 is inserted in the movable flange 5; a second spring member 6 configured to energize the movable flange 5 by one end portion of the second spring member 6; a spring receiver 7 to which the other end portion of the second spring member 6 abuts; a fixed flange 8 fixed to the other end portion of the joint member 4; and a chamfering member 9 fixed to the other end portion of the joint member 4, wherein the fixed flange 8 and the movable flange 5 have abutting surfaces formed by a flat surface, and an axial center of the chamfering member 9 substantially coincides with an axial center of the shaft member 2 when the abutting surfaces abut on each other.

A deburring method includes rotating a case, a sleeve and a drive gear together with a spindle of a machining tool; transmitting rotating torque from the drive gear to a driven gear to rotate a tip tool together with a reciprocating shaft; receiving reactive torque to the tip tool in a reverse direction of a rotational direction of the case by a workpiece contact with the tip tool so that the reciprocating shaft rotates in a reverse direction of the rotational direction with respect to the sleeve; moving the reciprocating shaft to a basal end direction against an elastic force of a second spring with the driven gear sliding with respect to the drive gear; and cutting the workpiece by the tip tool.
