Cincom L20X

Citizen innovation gives the next generation L20 more axes, more tools and more functions.

Introducing the L20X, with a new Y2 axis for versatile simultaneous machining using the gang and opposite tool posts.

New Y2 axis

To significantly increase the simultaneous front-back machining possibilities.

Increased back machining capability

8 tools on the back tool post in two rows of four, upper row driven, for the machining of complex features on the back spindle.

Up to 39 tools

To meet the demand to produce complex parts in a small machine footprint.

2 tool balanced turning and milling

“Pinch” turning and “pinch” milling by simultaneous use of gang tool post and opposite tool post.

Citizen’s renowned ease of use

Citizen is the machine of choice for fast set-ups and change-overs.

FEATURES:

Synchronous-Superimposed Operation
Cav Bar Feeder
Whirling Attachment
