DMG GILDEMEISTER SPRINT 42 linear CNC automatic lathe

DMG GILDEMEISTER SPRINT 42 linear CNC automatic lathe was built in 2006 in Italy by GILDEMEISTER Italiana S.p.A. The machin was regularly serviced and maintained throughout its entire service life, and underwent a major overhaul in 2018.

The DMG GILDEMEISTER SPRINT 42 linear is a high-performance automatic lathe designed for the automatic machining of workpieces with a maximum diameter of 42 mm. The machine enables precise turning, milling, drilling and threading of bar stock within a single process. Its wide range of machining capabilities, combined with reliable components, makes it an excellent choice for the mass production of complex components used in many industrial sectors.

Machining is performed using the main spindle and the sub-spindle. This solution allows operations to be performed on both sides of the workpiece without the need to re-clamp it. Once the first machining stage is complete, the workpiece is transferred to the sub-spindle, which continues the machining process from the opposite side. Both spindles reach a maximum speed of 6500 rpm and are equipped with a C-axis offering an indexing accuracy of 0,001°.

Automatic material feeding is provided by the IEMCA BOSS 545 E bar feeder, which handles bars with a maximum length of 3000 mm and a diameter of 33 mm. By using the appropriate channel, pusher and reduction tubes, the bar feeder can be adapted to handle material with a larger diameters. The machine is also equipped with an intuitive FANUC Series TB CNC controller and driven tools. The SPRINT 42 linear dual-spindle lathe weighs 4350 kg.
