Vertical turret lathes are cutting machines used to produce large formed components with rotational symmetry. They are some of the biggest lathes available.
Vertical Turret Lathes - Structure
Generally, vertical turret lathes require a massive cement foundation to ensure safe operation. Vertical turret lathes are made out of a very stable base frame, upon which a rotating plate is built. A high-end and very powerful electric motor is required to power the rotating plate. A transmission is used to ensure smooth running of the rotating plate and to regulate the rotation speed. There is a clamping device on the rotating table made out of at least three, but usually four, clamps. These clamps fix the workpiece in place, which is then processed on the rotating plate. A cantilever arm is attached to a side column, which is used to guide the chisel towards the workpiece.
Vertical turret lathes are used for particularly big components. The rotation speed of the machine is usually not as high as conventional horizontal lathes. Vertical CNC Lathe Turret regularly process workpieces with diameters and heights up to several metres. Due to their dimension and the slow rotation speed, the time it takes to process workpieces using this machine is very long. Work stages over two layers are common. High-end vertical turret lathes have several cantilever arms, so that they can work on up to three areas simultaneously.
Due to the fact that the workpiece is in a standing position, vertical turret lathes can be used to create very deep and complex internal contours.
Where are vertical turret lathes used?
Vertical turret lathes are usually used for producing special machines. They are suited for highly-precisely manufacturing large components. These kinds of components are generally used for, for example, ship engines, machine construction or defence technology. Only specialised staff should operate vertical turret lathes. There are several things that could transform the components produced on a vertical turret lathe to waste, including mistakes during operation, failing tools or wrong installation and adjustment. This has very expensive consequences. In order to avoid this, it is necessary for the turning process to be permanently monitored.
