Ultra Performance Bridge Type Machining Center
Representing YAMA SEIKI’s “The royal family of bridge machines” of mature manufacturing abilities and advanced technology skills, the SP and LP series bridge type vertical machining centers combine strong spindle power and high rigidity structure along with high quality automation equipments and full product line to provide you with high efficiency, high productivity machining strategies; it can be broadly applied in the automotive, precision mold, aerospace and energy industries., etc.
The LP series can be equipped with an automatic head changer and vertical / horizontal ATC system which turns into a 5-face machining center providing more cutting flexibility to meet your demands of today and tomorrow.
LP series Product Map
Thanks to our advanced developing skills and strict assembly process, gives the SP series ultra performance bridge type vertical machining center optimum rigidity, accuracy and efficiency.
The modular spindle design provides cutting flexibility for various working conditions.
High rigidity roller type linear guide ways on the X, Y axes offer heavy-duty cutting, fast movement and low abrasion capabilities.
The Z-axis is adopted with high rigidity box way which is hardened and precisely ground suitable for heavy-duty cutting conditions.
( Opt. : The Z-axis can be adopted with roller type linear guide ways if equipped with high speed direct driven spindle. )
High Rigidity Structure
One-piece base structure built with complex 4 guide ways is enlarged proportional to the length of the travel to eliminate working table over hang issue while ensuring maximum structural support. ( X travel longer than 6,000 mm may be in two sections due to transportation limit. )
Wide span symmetrical center-driven design with X-axis ball screw placed in the center of the axial movement provides high precision axial feeding features, avoids movement yawing problem and guide ways uneven wear out due to eccentric driven design as in other machine.
The ball screw vibration absorber reduces the vibration of long ball screw to increase machining accuracy.
LP-2516 / 3016 / 4016 / 5016 : one-piece base structure with 2 roller type linear guide ways design.
Optimum Spindle System
lnner-rail embraced structure provides high rigidity and gains good stress flow which minimizes over hang and vibration issues. The Y-axis roller type linear guide ways offset from each other increases structural rigidity reduces distance between spindle to cross beam enhances overall cutting performance.
Unique head design which the main spindle, spindle motor, ball screw and hydraulic counter weight cylinders are symmetrically placed. Hereby preventing thermal distortion and minimizing deflection. Assuring accuracy and heavy cutting capability.
