An innovative milling drive concept with masterhead as a compact, universal toolholder solution
Dörries VT 28
Higher productivity through complete machining due to integrated drilling and milling drive
Flexible robot tool-handling for an effective, expandable tool handling
State-of-the-art wear-free hydrostatic guides in all linear axes ensure optimal vibration damping and high precision
Vertical turning lathe
The Dörries VT 28 is based on the robust and durable features of the Dörries VCE series series, but it has been innovated from the ground up and brought the latest state of the art technology. It is designed for multifunctional, high-precision and flexible pre- and finish-machining.

Innovative Solutions
The use of head attachments and robot solutions underlines the multifunctional approach of this vertical turning maschine.
The master head concept for attachments enables the decoupling of the milling drive and tool interface and provides additional protection for the milling drive against collisions
On the the rotary table of the Dörries VT 28, up to 17 tons of heavy components with a maximum diameter of 2.8 meters and a height of 2.65 meters can be machined highly efficiently.
The compact single-column vertical turning lathe is not only suitable for turning, but also for drilling, milling and grinding with additional head attachments.
In the Dörries VT 28, wear-free hydrostatic guides in all linear axes ensure optimum vibration damping and high precision. The new hydrostatic system reacts extremely robustly to temperature fluctuations and changes in viscosity and thus enables maximum precision.
The Dörries VT 28 offers an option for compact floor installation, whereby the foundation base is onlyabove the ground, which results in lower foundation costs. The base of the column is part of the foundation, which leads to increased rigidity
Everything from simply part storage to most complex flexible manufacturing systems – even of the largest machines. The Starrag Group makes Industry 4.0 a reality.
