Key Features and Benefits
The LMV-L Series vertical machining center is engineered with high efficiency and high accuracy to satisfy the need for large quantity machining.
1— Eco-friendly design includes a skimmer that separates oils from the coolant, making
coolant cleaner and enabling it to be re-used instead of being discarded as toxic waste.
2— Optimized structure and one-piece bearing seat and base design enhance the rigidity
3— The one-piece bed and wide column base are heavily ribbed to prevent twisting
and distortion under even the most severe cutting forces. The rigid cast-iron
frame contributes to unparalleled damping characteristics.
4— Heavy duty and precise linear guideways on three axes are high grade, providing
stability and heavy cutting.
5— 3 axes direct transmission between servo motor and ballscrew that greatly boost your efficiency.
6— Legendary Levil service.
The LMV-L Series is built with linear ways for smooth quick movement
Machine Construction LMV-L Series
For machining precision, the LMV-L Series VMCs is designed with Finite Element Method (FEM) to calculate the displacements and stresses in the machine design due to operational loads. The series achieves superior stability with a high-density, dense cast iron construction of its main structure (base, table, column, saddle). Precision
is further enhanced by using pretensioned Class C3ballscrews in all three axes, which are built with linear ways for smooth quick movement; the large Y-axis gives more room for machining wider parts. Servo motors directly coupled to the ballscrews increase movement sensitivity while dramatically reducing backlash. The machine base is supported by full travel, making it suitable for high speed machining.
