Abstract: An orbital drilling device includes, on the same frame: a motor rotating a cutting tool on itself; a first, interior, eccentric, receiving the motor, mounted so as to be able to rotate; a second, exterior, eccentric, receiving the first eccentric, mounted so as to be able to rotate; a reference body, secured to the frame, receiving the second eccentric, mounted so as to be able to rotate; a first unit for driving the first eccentric; a second unit for driving the second eccentric, simultaneously with the rotation of the first eccentric; and a controller configured to reproduce any path of the cutting tool in the zone by continuous control of the angular offset between the first eccentric and the second eccentric.

Abstract: 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.
