A vibration assisted drilling system (102) is presented. The vibration assisted drilling system (102) comprises a drill feed motion system (106) having a drill feed axis (108), an oscillation motion system (110) having an oscillation axis (112), a drill spindle (114) having a drill bit (116), and a mounting system (118) configured to connect the drill spindle (114) to the oscillation motion system (110). The drill feed axis (108) is substantially parallel to and offset from the oscillation axis (112).

A power tool includes a tool main body including a first motor for outputting power to a tool attachment and a dust collecting device. The dust collecting device includes a fan, a second motor for driving the fan to rotate so as to generate absorbing force, a connecting assembly for connecting the dust collecting device with the tool main body detachably, a dust collecting housing connected movably with the connecting assembly in a front and rear direction. The second motor includes a stator and a rotor being capable of rotating relative to the stator about a first axis substantially perpendicular to the front and rear direction. The dust collecting housing is formed with a first containing chamber for containing the fan and a second containing chamber for containing dust absorbed by the dust collecting device.

The invention relates to a machining device comprising a framework, a transmission shaft (3) and a drive mechanism (1) comprising a rotation member (13) for driving said shaft in rotation about its axis (A), a drive member (18) in helical connection with the shaft to drive the translation thereof along its axis with a feed movement, according to the relative rotational speed of said rotation and drive members. The drive member is mounted with the ability to effect translational movement with respect to said framework along the axis (A) and is positioned between said rotation member and an end for coupling of said shaft to a cutting tool, while an electromechanical actuator (20) is mounted in a fixed frame of reference associated with said framework in front of said drive member (18) to which it can be coupled in order to cause it to oscillate translationally so as to superpose an axial oscillation component with said feed movement.

A rotary tool (11) for use with a rotary driving unit (12) for inserting a component (14,14′,14″) through a surface of a workpiece made of a material showing friction-induced plasticity such as aluminum, includes a tool body (22) having a working end (24) defining a shoulder portion (26) and a securing device (28,28′) for selectively engaging the component to impart rotation thereof in a first direction while applying an axial force of a sufficient magnitude onto the component to produce insertion thereof by plasticizing the material through friction. The shoulder portion is provided with a deburring device (34) capable of being displaced from an inoperative position upon rotation of the tool body (22) in the first rotation direction (30), to an operative position whenever the tool body is caused to rotate in an opposite direction (30′), to provide deburring of the workpiece surface.

The invention relates to a drill (1) particularly for working lightweight metals and composite materials, having a central axis (M) and an end face (3). The drill (1) comprises a first section (5) which – seen along the central axis (M) from the end face (3) – is arranged before a second section (7). Said first section (5) comprises a first main cutting edge (9, 9') and a first external diameter (D 1 ), said second section (7) comprising a second main cutting edge (11) and a second external diameter (D 2 ). Said first external diameter (D 1 ) is smaller than said second external diameter (D 2 ). According to the invention, the first external diameter (D 1 ) is at least 0.9*x to a maximum of 1.1*x, where x = D 2 – exp(D 2 /15) – 0.5.
