KOMBINIERTE DREHMASCHINE MIT NC STEUERUNG

摘要

It is an objective to provide a composite NC lathe capable of processing works of a variety of shapes throughout from a state of a raw material to that of finished products on the same machine and having a high productivity. This lathe is provided with a left turret rest (8L) and a right turret rest (8R) positioned on the lower front side of a left main shaft 1L and a right main shaft 1R facing each other on the same axis; a third tool rest (6) positioned on the upper rear side of the main shafts (1L, 1R) and provided with a tool spindle (14); a tool magazine 19 holding tools therein which are to be fixed to the third tool rest (6); and an automatic tool changing device (20). The main shafts 1L, 1R is provided with main shaft motors (4L, 4R) capable of controlling a C-axis and being driven independently of and synchronously with each other. The tool spindle (14) on the third tool rest (6) is capable of controlling the directions of a Z-axis, an X-axis, a Y-axis and a B-axis and fixing the rotations thereof.
