Abstract: A resonant frequency dampened through-coolant machine tool for selective mounting to machining systems for precision vibration free machining and has an elongate tool body. An internal dampening chamber is defined within the machine tool body and contains a resonant frequency dampening mass that is moveable within the dampening chamber. Axial and diametrical tunable dampening devices support the dampening mass in spaced relation with internal walls of the dampening chamber. A tuning piston is moveable within the machine tool body and has a tuning flange that is disposed in contact with one of the axial tunable dampening devices. The tuning piston has a pair of oppositely angulated surfaces that are selectively engaged by angulated drive heads of adjustment screws that are supported by threaded openings of the tool body and are rotated to selectively drive the tuning piston forwardly or rearwardly for precise tuning activity.

Abstract: A docking assembly for docking and retrieving a filament holding device includes a motor casing rod defining a recess, filament holders and docking stations. Each filament holder defines a filament receiver channel for receiving the rod and a stop member that is selectively engaged with the recess of the rod, thus coupling a filament holder to the rod for retrieval of the filament holder. Each docking station includes a deployment latch operable to rotate when the rod is inserted into the docking receiver channel so that the deployment latch urges the stop member to the deployed configuration for coupling together the rod and the filament holder. Thus, a filament holder is captured for removal from the docking station. The docking apparatus includes a release lever that operates in reverse of the deployment latch so as to release a filament holder from the rod back to its docking station.
