L20X – Cincom Innovation Line

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

New Y2 axis significantly increases 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 changeovers
Citizen’s unique Cincom Control cuts non-cutting time to a minimum. Citizen’s dynamic software development leads the Swiss type/sliding head sector.
Tool layout is quickly changeable – The layout is easily adapted to suit highly diverse types of workpieces

Performs simultaneous machining with the gang and opposite tool posts and enables improved division of processes between the front and back faces.

Example of simultaneous machining: pinch milling

Simultaneous machining such as pinch turning and pinch milling using the gang tool post and opposite tool post reduces the cycle time for machining on the front face.

*The rotary tool specification for the opposite tool post is an option.

Division of processes between front and back faces

The increased tool capacity of the back tool post at 8 has made it possible to perform back machining (conventionally done with the gang tool post) by using the back tool post. The total cycle time can be reduced by division of processes.
