Sliding Headstock Type Automatic CNC Lathe

Cincom L20

Full Model Change of the Cincom L20 Basic performance and operability are greatly improved.

The Cincom L20 has evolved into its 3rd generation, offering a lineup of 5 models range from the cost-effective type VIII to the type XIIB5, which allows for simultaneous 5-axis control.

The new L20 helps reduce downtime by Citizen’s proprietary LFV (low-frequency vibration cutting) technology for both front and back machining.
In addition, the new back spindle with improves acceleration/ deceleration by the higher output helps to shorten cycle times.
The maximum number of turning tools that can be mounted on the gang tool post increase to six to avoid tool shortage.
The high-end model L20XIIB5 supports simultaneous 5-axis control and can perform complex machining in conjunction with a CAM system.
The L20 has evolved toward sustainable manufacturing with its improved environmental performance that supports our efforts to reduce CO2 emissions, including reducing air consumption through optimal air control and visualization of environmental information.
