Abstract: The invention relates to a machining unit in which the pieces are carried by an electric turning spindle radially arranged on a turret with a vertical axis of rotation. On rotation of the turret the pieces are successively introduced into machining stations, arranged peripherally around said turret and comprising tool support means. A large space is thus available around the periphery of the machine for housing the tools. The electric turning spindles are adapted to selectively hold the pieces at any fixed angle, thus permitting not only turning operations but also other machining operations on fixed pieces.

Abstract: The single point machining head includes a probe that is removably mounted on a carriage that moves radially relative to a central axis of the machining head. A system controller moves the carriage in a radial direction while the machining head is fed in a vertical direction so that the probe contacts the surface of a workpiece. Each point of contact on the workpiece becomes a datapoint including the radial position and the vertical position when contact occurred. The surface of the workpiece is scanned with the probe and a profile is generated using the points of contact. A system controller calculates a difference between the measured profile and a desired profile to be machined to determine the amount of material to remove.
