Cincom L20E Type IX

Citizen’s highly successful L20 series evolves for the new age to meet the needs of the drastically changing global market

The Cincom L20E is a state of the art Swiss turning center that features the All-axis Simultaneous Cincom System M7 control (Mitsubishi Meldas 70LPC). The standard seven cutting axes (X1, Y1, Z1, X2, Z2, C1, C2) and one bar loader axis (A7) can make easy work of your toughest applications.

Compared with earlier generations of the L Series, the L20E delivers substantial improvements in productivity. Under the same cutting conditions of spindle speed and feed rate, Citizen's Cincom Control, in conjunction with increased rapid feed rate has reduced cycle time significantly. The L20E offers the additional advantage of faster set-up and lower maintenance costs.

The user-friendly editing function which utilizes multi line, multi axes programming, along with superimposed and synchronized control make setting up the most complex jobs easy.
