Tool layout with guide bush(Shown with back rotary tool option)
BackrotarytoolMax.spindlespeed:90,000min-1Motor:0.5kW
Building on the legacy of Citizen’s L series machines, setting the benchmark of functionality and performance.
Outstanding performance for machining high speed, small diameter application with 15,000 rpm on main spindle and 10,000 rpm on sub spindle.
Now with the added flexibility of using in either standard guide bush or non-guide bush mode with simple setup of both modes.
The regular guide bush can be used for long or slender parts. The non-guide bush mode can be used for short parts to save material wastage.

Equipped with high-speed NCThe 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. This feature provides stress-free operation environment.
On-machine program check functionThe program can be run round using the handwheel giving enhanced user confidence. The program can run in forward or reverse directions and can be paused to edit before restarting.
Display of easily understood illustrationsIn response to the selection of an item, the corresponding illustration is displayed on the screen so that the operator can easily recognise the meaning of the selected item. (The screen shown above displays the machining data).
Display of code listThe function displays the list of G and M codes including explanations of each code.
Eco ScreenThe current power consumption is shown on the screen, along with the maximum power consumption value, the power consumption record, the cumulative power consumption and the power regeneration (generation) status. Data can be output too.
Eco ScreenThe machine’s power consumption can be shown in the form of an easy-to-understand graph.

1. LFV machining cannot be performed with the Y axis.2. Up to one pair (= two axes) can be operated simultaneously as LFV machining.3. LFV machining using rotary tools requires the "LFV function" and "Rotary tool per rotation
feedrate" options.* LFV is a registered trademark of Citizen Watch Co., Japan.
LFV* (low-frequency vibration) cutting is a technology for cutting in which each X/Z servo axis is vibrated in the cutting direction and synchronized with the spindle speed. This reduces various types of problems such as cutting chips being caught up in components, workpieces or cutting tools, and enables small-diameter deep hole drilling and machining of materials that are difficult to cut.
A maximum of 27 tools can be mounted. A drilling tool can be added to the opposite tool post, which is effective for deep hole machining.
