L12 Sliding Headstock Type CNC Automatic Lathe The L12 - The perfect solution for small diameter work with switchable guide bush and 15,000 rpm spindle

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 applications 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.

Achieving optimum machining conditions Rotary tool on the gang tool post Z1Z1 High-speed spindle and rotary tools Max. spindle speed The maximum speed of the front spindle is 15,000 min-1 10,000min-1 even when using a rotary guide bush (maximum Motor: 0.75kW machining length: 135mm per chuck), and rotary tools 1X1 are able to reach speeds of 10,000 min-1. This makes it possible to use the optimum machining conditions when 1Y1 machining small diameter bar material or using small diameter drills or end mills.

Handles workpieces with complex shapes Front spindle Max. spindle speed: Comprehensive tooling 15,000min-1 (GB) -1 A full range of optional tooling is available.Three double 12,000min (GBL) Motor: 2.2/3.7kW ended rotary tools (angle adjustable from 0° to 30°) can be mounted among the rotary tools on the gang tool post. 2Z2 In addition, adopting rotary tool specifications for the X22 back tool post has made it possible to mount end face rotary tools and a slitting spindle for back machining. Improved productivity per unit area Compact design The design is only 1,760 mm wide by 820 mm deep. Back spindle Back rotary tool You can introduce a high-productivity, 5-axis machine Max. spindle speed: Max. spindle speed: -1 -1 into the same space as required to install a B12 machine 10,000min 90,000min up until now.

Automatic lathe offering 2 part lengths in 1 machine: handles both long and short workpieces

Ability to switch between guide bush and non-guide bush modes

Now available with easy to change switchable guide bush. 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.
