DANOBAT NA 750 CNC lathe

The DANOBAT NA 750 CNC lathe was built by the Spanish company Danobat S. Coop. in 2001. The machine body is made of MEHANITE alloy characterised by high rigidity and excellent vibration and shock absorption. Its 60-degree angle of inclination facilitates the mechanical or manual removal of the swarfs.

The spindle of the machine consists of a main spindle running on bearings and a belt pulley receiving the rotary motion. The main spindle is driven by the main motor through a belt. The tailstock with Morse MK5 cone is made of steel with increased hardness to ensure long-lasting operation.

The DANOBAT NA 750 lathe equipped with a SIEMENS Sinumerik CNC control processes a workpiece in X and Z axes with maximum feeds of 255 mm (X axis) and 520 mm (Z axis). The workpiece can have a maximum diameter of 700 mm above the bed. The machine is also equipped with a HEINDENHAIN LS186 ML340 optical measuring scale and a DUPLOMATIC tool head.

The DUPLOMATIC tool head, with a capacity of 12 tools, ensures easy and fast tool changes. It has been manufactured in such a way as to ensure that the tools have access to the entire workspace. The Couvic-Coupling positioning system always selects the shortest tool change path.
