A machine tool for machining semi-finished aluminum or titanium alloy products has a supporting structure, an upright, a carriage and a working head. The supporting structure has a bench and a rear support rigidly connected to each other. The bench extends along a longitudinal direction, while the rear support extends both along the longitudinal direction and along a vertical direction. The supporting structure is provided with upright translation elements. The upright is connected to the supporting structure by the upright translation elements so as to translate along the longitudinal direction and is provided with carriage translation elements. The carriage is connected to the upright by the carriage translation elements so as to be translatable along the vertical direction. The machine tool has a first pair of carriage moving ratio motors and a second pair of carriage moving ratio motors positioned aboard the upright and engaging the carriage translation elements.

A parts feeding apparatus includes: a parts feeder disposed on one side of a worktable where work is performed and having a plurality of feeder slots each for loading at least one parts box; a position mover adapted to load the parts boxes onto the parts feeder or unload the parts boxes loaded on the plurality of slots to move the parts boxes horizontally or vertically; a parts storage unit located to face the parts feeder and having a plurality of storage unit slots for loading at least one or more parts boxes to store the parts boxes to be fed to the parts feeder therein; and a control unit adapted to control the parts feeder and the position mover so that the parts boxes are changed in position and aligned.

A processing mechanism for machining a workpiece includes a fixing base, a driving member, a connecting member, a cutter and a spring. The driving member is positioned above the fixing base. The connecting member is coupled to the driving member. One end of the cutter is fixed to the connecting member, and the cutter can be driven to pass through the fixing base to machine the workpiece positioned under the fixing base. The spring is positioned between the connecting member and the fixing base. The spring is compressed when the driving member drives the cutter away from the fixing base to machine the workpiece, and the spring under compression biases the cutter back toward the fixing base. The disclosure also supplies a processing device using the processing mechanism.

A handheld machining device (1), particularly for drilling, having a mechanism includes: a first mounting (20), on which a tool holder (2), and a motor (3, 4) arranged to rotate the tool holder (2), are mounted; a second mounting (30); and an element (40) for translatably guiding, between the first mounting (20) and the second mounting (30), a linear actuator (5) enabling the first mounting (20) to be spaced apart from the second mounting (30), and the first mounting (20) to be brought toward the second mounting (30). The motor (3, 4) is electric, and the rotor (4) of the first motor (3, 4) is directly mounted onto the tool holder (2) and is rigidly connected thereto.

A cleaning station may include an input nest that receives a device and transfers the device to a first rotation nest. The first rotation nest may position the device under a first nozzle and rotational nozzles. The first nozzle may clean a first face of the device with dry ice pellets, and the rotational nozzles may clean a first pair of sides of the device with dry ice pellets. The first rotation nest may rotate the device ninety degrees, and the rotational nozzles may clean a second pair of sides of the device with dry ice pellets. A second rotation nest may remove the device from the first rotation nest and may position the device over a second nozzle. The second nozzle may clean a second face of the device with dry ice pellets, and the second rotation nest may transfer the device to an output nest.
