L20-VIII / X / XII B5 / XII ATC
Full Model Range Upgrade For The Cincom L20 CNC Sliding head
The full model range includes the L20 Type VIII, X, XII B5, and XII ATC – each designed to meet a range of machining needs from standard configurations to advanced, high-output production environments.
Cincom L20 now delivers enhanced performance and smoother operability – engineered for precision and built with sustainability at its core.
The new L20 CNC Sliding Head helps reduce downtime by enabling the use of Citizen’s proprietary LFV (low-frequency vibration cutting) technology for both front and back machining.
A more powerful back spindle boosts acceleration and deceleration, cutting cycle times significantly. With capacity for six turning tools, you can maintain momentum and maximise throughput – without the interruptions of tool change delays.
For added versatility, the L20 can also be configured to machine up to 25mm (1.0″) diameter bar capacity, expanding its application range for more demanding components.
The high-end model L20XIIB5 supports 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.
From the view point of environmental protection, 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 visualisation of environmental information.
