L20Sliding Headstock Type CNC Automatie Lathe
Our best-selling L20 completely renewed.A machine synonymous with the history of Cincom has been designed for the new age with 3 models in modular design. Ranging from a 5-axis machine with excellent cost performance to a high-end machine equipped with B axis and a back spindle Y axis, you can select the machine according to the functions you require. This concept offers unrivalled versatility with two types of gang tool post, five types of opposite tool post and three types of back tool post are available to be specified according to the functions required.

Guide bushing typeGuide bushing-less type
Ability to use as a guide bushing type or guide bushing-less type by switching between them
Either type can be selected as appropriate, when machining lang, thin workpieces, when using cold drawn material, and in order to leave short remnant bars.
Cincom L20, Type XII [Example tooling]
Stable, powerful, and highly productive with versatility of modular design.
With the current shift in manufacturing industry, the requirement is for variable-lot machining of a wide range of workpieces. In order to meet this requirement, Citizen has introduced modular design. We allow the selection of functions corresponding to a diverse range of machining needs, and help customers to optimize their manufacturing by combining these functions to achieve their ideal machine configuration.

Optional
Position adjustable operation panel
By swiveling the position adjustable operation panel, you can perform operations while viewing the machining area.
ln-machine lighting
Low energy LED lighting provides excellent brightness, clarity and visibility.
NC program 1/0
NC programs can be input and output using a USB memory stick or compact flash card.
Citizen‘s renowned „ease of use“
Ø 20 mm max. bar as standard; Ø 25 mm as option
Supply of bar stock up to Ø 25 mm is supported as an option. The machining length per chucking is 200 mm (Ø 20 mm) and 188 mm (Ø 25 mm).
The lang workpiece unit (option) supports work-pieces up to Ø 20 mm.
Cincom L20, Type VIII [Example tooling]
Function modules that can be combined without restrictions
Features a B axis for rotary tools on the gang tool posts of Type IX ° and XII machines ° as °standard; it can be set over a 135 range from 90 to -45 .
For the opposite tool post, a tool post that is capable of pinch milling or one that can handle deep hole machining can also be selected as options.
The back tool post on Type X and XII machines can accommo-date a total of 8 tools: 4 rotary tools in the upper row and 4 fixed tools in the lower row.
Selectable modules to improve your productivity and profitability.

Equipped with high-speed NC
The machine is equipped with the latest NC model to drastically reduce the start-up and screen switching time compared to conventional machines with advanced functions.
On-machine program check function
Using manual handle feed, operations can be run in the forward or reverse directions, and you can temporarily stop program operation, edit the program, and then restart operation.
Display of easily understood illustrations
Illustrations appropriate for each item are dis-played. You can see what they mean at a glance (the screen shown above displays the machining data).
Display of code list
The function displays the list of G and M codes including explanations to aid programming.
Eco screen
The current power consumption is shown on the screen, along with the cumulative power consump tion, and the power regeneration (generation) status.
Eco screen (example graph display)
The machine‘s power consumption can also be shown in the form of an easy-to-understand graph.
Advantages of the new functionality and visualization
Intuitive screen display is readable at a glance.
The Latest NC model reduced drastically the start-up and screen switching time which makes the intuiti-ve operation more confortable and enjoyable, the machining data more understandable and not least it´s allowing a clear visualization of the machine power consumption in the form of a graph.
Multiple tool post overlapping function
Independent opposite and gang tool posts are provided. In front machining, idle time has been completely eliminated by using a unique control method whereby the tool post to be used next starts the preparation for machining without waiting for the other one to complete its retraction operation.
Direct spindle indexing function
This substantially reduces spindle indexing time. When indexing the spindle, this function allows the spindle to be decelerated and stopped at the required index position by specifying this position with a C-axis command while the spindle is rota-ting. This eliminates the idle time up until rotation stops, and improves working efficiency.
Tue next process starts before the current one ends.
We have developed a new control system unique to Citizen that realizes fast and smooth operation. lt reduces idle time and achieves faster rapid feed together with substantial shortening of cycle times.
