Have you seen these flexible cobot and robot solutions for aerospace parts?
With an entire spectrum of automation solutions from Starrag and Fanuc, there’s no end to what…
The Starrag Dörries product range is recognised as an innovator in the heavy-duty machine tool sector. The world-leading manufacturer is again demonstrating this with its latest innovation, the new Dörries VT 28 vertical turning centre.
Developed for one-hit machining of large components in the aerospace, power generation and offshore sectors, the Dörries VT 28 is the epitome of performance, accuracy and long-term stability. The exciting new Dörries VT 28 combines the proven technology from the successful Dörries CONTUMAT VCE series, introducing a raft of innovative solutions and technologies to enhance your machining performance and productivity.
Capable of efficiently machining heavy components up to 17 tonnes with a maximum diameter of 2.8m and a height of 2.65m, the Dörries VT 28 has been developed as a multifunctional, high-precision, and flexible vertical turning centre for everything from rough to finish machining in a single operation. To achieve this, the compact single-column vertical turning lathe is suitable for turning, drilling, boring, milling, grinding, and much more.
Constructed with a single-column design that optimises static and dynamic rigidity whilst guaranteeing compact on-floor installation, the Dörries VT 28 column base is cast above ground to minimise foundation costs. The column base forms part of the machine foundations, increasing rigidity, performance and stability whilst minimising installation costs and machine footprint. From a dimensional perspective, the Dörries VT 28 offers a 2.8m swing diameter and a 2.5m table diameter that permits the machining of exceptionally large components. As expected with a Starrag Dörries machine, the VT 28 offers class-leading torque of 11kNm with 98kW on the main S1 drive and a speed range of 250U/min. This enables end users to wield vast depths of cut at high machining parameters whilst ensuring maximum stability, rigidity, performance and surface finishes.
Further enhancing the stability and rigidity characteristics of the Dörries VT 28 are wear-free hydrostatic guides in all linear axes that maximise the vibration-damping performance. This new hydrostatic system reacts with minimum fluctuation to temperature deviations and changes in viscosity, providing the end user with unsurpassed precision and repeatability.
From a flexibility standpoint, the Dörries VT 28 has a ‘master head’ concept that enables the de-coupling of the milling drive and tool interface to provide additional protection against collisions. The Dörries VT 28’s flexibility also allows end users to integrate gear-driven spindles, motorised spindles, and fork-type heads and undertake grinding operations. From an operational perspective, the Dörries VT 28 has been ergonomically designed with a central layout that offers easy access for the users and service personnel.
This design makes daily operation a delight for shop floor staff, and it also supports automation with flexible robotic tool handling that is available to expand the machine’s potential. Of course, tool life and performance is maximised by the Dörries VT 28 with its 350bar high-pressure coolant system that easily breaks chips and evacuates them from the work envelope.
