L20 Sliding Headstock Type CNC Automatic Lathe The new L20 – now with 4 models each can be specified to deliver the functions you need: from simple to complex workpieces and for small, medium and large lot sizes

The new L20 - 3 models to choose from

A machine synonymous with the history of Cincom re-designed for the new age with 3 versions depending on your requirement. From a 7 axis machine with excellent cost performance ratio to a high-end machine with B axis capability on both spindles and a back spindle with an additional Y axis. An easily removable guide bush is also standard enabling the machine to run in non-guide bush mode for shorter parts. The machine is also capable of using up to 25.4mm / 1” material with optional expansion kit.

L20 | Citizen 3

Designed for optimum usability

The L20 has adopted a modular design, but also focuses on operability and working convenience.

The high level of basic performance found in features like the adjustable operation panel that makes it possible to monitor the interior of the cutting room while looking at the operation screen, the centralised lubrication system that helps to lessen the maintenance workload and the coolant tank with a wide opening to facilitate chip clearance, makes the operators’ daily work run smoothly.

What is more, material up to 25.4mm (1”) can also be supplied as an option. This expands the range of machinable workpieces beyond what was possible with the previous L20.

LFV Function (optional)

LFV* (low frequency vibration) is Citizens’ latest, unique control eeenttin te ttin technology which oscillates the X & Z servo axes in synchronisation with the spindle. eeenttin te ttin It offers unprecedented levels of chip control and is highly effective for both small diameter drilling and when machining difficult to cut materials.
