L20E-3M8 | L20E-3M10 | L20E-3M12B5 (ATC)
The Cincom L20 performance and operability have been greatly improved and the machine has evolved to become environmentally friendly.
Typical Parts
The new L20 helps reduce downtime by enabling the use of Citizen’s proprietary LFV (low-frequency vibration cutting) technology for both front and back machining.
In addition, the improved acceleration/deceleration due to the higher output of the back spindle helps to shorten cycle times. Tool shortages have been eliminated by increasing the maximum number of turning tools that can be mounted on the gang tool post to six.
The L20XIIB5 and the L20XIIB5-ATCsupports simultaneous 5-axis control and can perform complex machining in conjunction with a CAM system. As for operation, the large touch panel screen greatly improves ease of use.
Our EcoBalance L20 Series 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.
