Four Core Technology Advantages
Integrating cutting-edge technologies such as magnetic levitation, linear motors, and permanent magnet electric spindles to redefine precision grinding standards
High Vibration Damping
The base and bridge of fixed components are made of integral mineral casting, providing excellent vibration damping performance to ensure stable machining processes.
High Cutting Capability
Permanent magnet synchronous electric spindle with ultra-high speed grinding significantly improves machining efficiency while ensuring excellent surface quality.
High Precision
Linear motor drive with zero backlash transmission and zero wear design maintains stable machining precision over the long term.
5-Axis Simultaneous Machining
Combined with cradle-type 5-axis, it enables integrated machining of complex components, expanding the application range.
