ABSTRACT:
An NC lathe includes a bed, a headstock mounted on the bed for rotating a work around C-axis, a tailstock slidably mounted on a first guide surface formed on the bed, and a carriage slidably mounted on a second guide surface formed on the bed in a direction of Z-axis parallel to the C-axis and juxtaposed with the first guide surface. The carriage has a saddle having a first slide surface for contacting the second guide surface of the bed and a second slide surface inclined at a predetermined angle with respect to the first slide surface. A slide base is slidably mounted on the second slide surface of the saddle for movement in a direction of Y-axis perpendicular to the Z-axis. A column extends from the slide base substantially perpendicular thereto and includes a column body which has a guide surface in a direction of X-axis perpendicular to the Z-axis and to the Y-axis. A cross slide is slidably mounted on the guide surface of the column body in the direction of the X-axis and includes a driving device. A tool spindle is rotatably mounted on the cross slide around B-axis perpendicular to the X-axis and to the Z axis and has a spindle rotatable around an axis perpendicular to the B-axis.
