The Cincom L12 type VII is a state-of-the-art Swiss Turning Center featuring the ALL axis Simultaneous Cincom System M7 Control (Mitsubishi Meldas 70LPC).  The user-friendly editing function, which utilizes multi-line multi-axes programming along with superimposed and synchronized control, makes setting up the most complex jobs easy.

 

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.
