LC-450
Unique Motion Construction
L450 features Yuzhong's unique moving column motion construction, which can not only easily meet the turning of generic parts, but also machine the both sides of a brake disc with the dual-tool function thanks to the modular design, allowing for a wide range of applications.
Upgraded spindle
For high-speed precision cutting, any small vibration will affect the tool life. The newly upgraded spindle unit can operate at high speed and is rigid enough.
Moving column construction
The industry-leading movable column construction brings more stable accuracy, and service life of transmission parts is significantly improved.
Bearing diameter fromΦ120mmupgraded toΦ130mm
Spindle rigidity+18%Spindle load+27%
Cutting efficiency+10%Tool life +8%
