Vertical Turning Lathe (VTL) Machines
Ideal for larger and heavier rounded or cylindrical parts, vertical turning lathes — also known as VTL machines or vertical boring mills (VBMs) — flip a traditional lathe design on its end, employing gravity to help hold the workpiece in place. Our VTL machines utilize many of the same quality components and the same portal structure as our vertical milling machines — the key difference is the integrated rotary table which handles the turning operations.
With available table diameters ranging from 2.5 to 16-plus meters, Waldrich Coburg’s vertical turning lathes can accommodate the most complex, difficult-to-machine parts.

Frequently Asked Questions
What is the difference between a vertical milling machine and a vertical turning machine?
The primary difference between a vertical milling machine and a vertical turning machine is whether the workpiece is moving or the cutting tool is moving. A vertical mill uses any number of spinning tools attached to a spindle axis to clear away material from a stationary workpiece attached to a machine table. In contrast, a vertical turning machine, also called a vertical turning lathe (VTL), rapidly rotates a workpiece against a stationary cutting tool.
What are hydrostatic guideways and why are they desirable?
Hydrostatic guideways share a similar design with box ways, but avoid metal-on-metal contact by utilizing a pressurized oil film that the axis rides on. This is desirable for several reasons, including virtually no guideway wear and superior vibration damping. Because they are subject to less stress and vibration, they are able to hold up to large and demanding machining tasks over a long period of time.
What industries can benefit from vertical turning lathes?
Industries with large components which may or may not be symmetrical can benefit from vertical turning lathes. These industries include but are not limited to: power generation, bearing manufacturing, gear ring manufacturing, shipbuilding, and more.
How do I determine which vertical turning lathe is right for my operation?
To determine which vertical turning lathe is right for your operation, consider first the types of operations that should be performed on the machine: turning only or turning and milling. Simple turning-only operations may only require a basic machine whereas turning and milling may require a more complex machine with an automatic tool changer and automatic head changer.
