DownloadModular Lathe for Vertical 4-Axis Shaft Machining
Four axes, short travels, a powerful main spindle – these are the strengths of the VT 2 turning machine. The use of a “two-sided” process massively reduces machining times on VT lathes, allowing for large component batch sizes to be manufactured quickly.
Flexibility is guaranteed with the use of two tool turrets, each with eleven stations, all of which can be equipped with turning tools and driven tools. Automation is fully integrated on these lathes, as the turret loads and unloads workpieces into the machining area. While one gripper, occupying the twelfth position of the turret, conveys a new raw part into the machine, the other removes the finished component. This changeover process takes only six seconds, depending on the workpiece.

Advantages
- Shorter cycle times through four-axis machining
- Less investment required in sensors, as the machine axes are direct driven and the machine’s control system is of the latest design
- Short setting and resetting times owing to great machine accessibility and operator friendliness
- Less operator intervention (tailstock and steady are CN-controlled, the turrets can be accessed directly)
- The vertical construction of the machine and the resulting free chip flow prevent the creation of chip clusters
- Less expense for automation and peripherals
- Raw-part and finished component storage form an integral part of the machine
- Reduced idle times through cycle time-concurrent loading and unloading
- The machine can be used as a stand-alone or in a production line
- The compact, vertical construction of the machine makes for a small footprint
