ABSTRACT:
A turning machine or more precisely a numerically controlled lathe consisting of bed and column or base having said bed a cross section of substantially trapezoidal shape having in its upper part parallel prismatic guideways arranged in accordance with two inclined planes for supporting and/or sliding of the headstock, tailstock and carriages with indexable toolholder, said inclined planes intersecting above said bed, and said parallel prismatic guideways which permit free movements between the carriages mounted on separate guideways and free movements between one of the carriages and tailstock which are mounted on separate guideways, without interference between all of them along the whole useful length of said separate parallel prismatic guideways. A transmission box for automatic speed change can be mounted also on the guideways opposite to the headstock guideways, said transmission box being servo-operated by means of clutches being the output shaft of said transmission box coaxial to the output shaft or main spindle of the headstock, being said headstock fixedly mounted on the same prismatic guideways for the tailstock. A bed and column or base assembly of unique design allows the free flow of a large volume of chips removed during machining, said column or base allowing the easy installation of a chip conveyor either longitudinally or transversally in respect to the lathe.
