Cincom SERIES L12 VII / L12 X

The Cincom L12 is a state-of-the-art Swiss Turning Center featuring Citizen’s user-friendly editing function, which utilizes multi-line multi-axes programming along with superimposed and synchronized control. The L12 is equipped with a detachable guide bushing as standard. This allows the machine to be used as a regular guide bushing type automatic lathe for long and small diameter workpieces. Once the guide bushing is removed, it can be used to machine short workpieces with less material waste.

In addition, the new L12 Type X includes more features for improved performance, function and ease of use, such as:

Modular tooling system on the gang and back tool posts allow a wider variety of tooling layouts.
Y2 Axis on the back spindle expands the range of usable tools.
Back spindle has been switched to a built-in motor type that allows a maximum speed of 12,000 rpm.
Optimal balance of strength and weight greatly improves rigidity
