Abstract:
Lathe, comprising:a machine frame arranged on a support surface and having a base frame and a machine base member suspended on said base frame, the machine base member being elongated in a longitudinal direction, the machine base member having a first support section and a second support section arranged to follow this in the longitudinal direction, each of the support sections extending from a base side, a spindle support side located opposite said base side in a first transverse direction in relation to the longitudinal direction, said spindle support side extending in a plane essentially parallel to a plane defined by said base side, and two slide support sides located opposite one another in a second transverse direction in relation to the longitudinal direction, said second transverse direction extending perpendicular to said first transverse direction, and said slide support sides being located between the base side and the spindle support side, a first working spindle with a first workpiece receiving means, said spindle being arranged on the machine frame and drivable for rotation about a first spindle axis, the first working spindle being supported on the spindle support side of the first support section, at least one first tool slide for displacing a tool carrier in an X direction transversely to the first spindle axis so that a workpiece held in the first workpiece receiving means is machinable with at least one tool held on the tool carrier, the first tool slide being mounted for movement in a Z direction essentially parallel to said first spindle axis on one of the slide support sides of the first support section, such that the first tool slide is essentially entirely supported by the corresponding one of the slide support sides, a second working spindle with a second workpiece receiving means facing the first workpiece receiving means, said second spindle being arranged on the machine frame and drivable for rotation about a second spindle axis, the second working spindle being supported on the spindle support side of the second support section, at least one second tool slide for displacing a tool carrier in an X direction transversely to the second spindle axis so that a workpiece held in the second workpiece receiving means is machinable with at least one tool held on the tool carrier, the second tool slide being mounted for movement in a Z direction essentially parallel to said second spindle axis on one of the slide support sides of the second support section, such that the second tool slide is essentially entirely supported by the corresponding one of the slide support sides.
