The present application relates to a device (1) and a method for machining a seat face of a mechanical part, comprising a tool holder (3) that is rotatable about an axis (2) and is provided with at least one peripheral cutting blade (9). Said device further comprises an abrasive machining tool (10) which is secured to rotate with the tool holder and which has at least one abrasive surface (29), said abrasive tool being mounted on the tool holder (3) and being secured to said tool holder by elastic means (23) that allow the abrasive tool to axially move in relation to the tool holder.
The invention relates to a device for propelling a navigational seacraft, including: a propulsion means (34); an engine (10) driving a transmission shaft (30) for providing an engine torque (10) to the propulsion means (34), said transmission shaft (30) totally extending perpendicular to a propulsion axis (P) of the device; and an engine torque transmission means (11) comprising an engine shaft (17) capable of driving the transmission shaft (30), the engine shaft (17) being driven by the engine (10) and extending perpendicular to the transmission shaft (30).
