Box-Type Ribbed Structure · Max Vibration Damping & Rigidity
The castings feature a grid-like reinforcing rib layout inside. Combined with the ultra-wide base and large-section column design, the overall rigidity is significantly enhanced, effectively suppressing cutting vibration and ensuring stable machining accuracy even under heavy cutting and interrupted cutting conditions.
Integral Casting for Ultra-Stable Bed
Key components including the bed, column, saddle, and headstock are integrally cast from high-grade cast iron. After multiple artificial aging / vibration aging treatments, internal stress is thoroughly eliminated, ensuring zero long-term deformation and laying a solid foundation for consistent, reliable machining performance.

Thermally Symmetric Structure
The spindle head features a thermally symmetric structural design to enhance controllability of thermal deformation. Equipped with physical temperature control structure paired with advanced thermal insulation technology, it effectively lowers thermal expansion of the spindle box and secures stable machining precision throughout the cutting process.
ATC+ Large-Capacity Tool Magazine
Equipped with pre-tool selection function, the ATC enables faster tool change to shorten auxiliary machining time and boost processing efficiency.
The 24-station large-capacity magazine accommodates cutting tools for sophisticated multi-operation machining and improves overall machine utilization rate.
Box-way Worktable
C3 Grade Pre-stretched Ball Screw (THK ball screw is available as optional upgrade)
Standard equipped with C3 precision ball screws with exclusive pre-stretching manufacturing process, which effectively minimizes thermal expansion-induced precision loss caused by screw heat generation, upgrades overall machine accuracy, and improves anti-deformation performance & long-term precision retention.
Accuracy and Rigidity, Double Guaranteed
High Rigidity：Box-type contact design provides superior vibration damping, ideal for heavy-duty cutting.
Long-term Accuracy：Hardened & precision-scraped surface ensures consistent performance over years.
Proven Reliability：The guideway system is widely adopted in high-end machine tools worldwide.
Upgraded Y-axis Rear Guard with Chip Flushing Device
The Y-axis rear guard is upgraded from single-layer to inclined double-layer structure for improved rigidity and anti-deformation performance. Equipped with integrated chip flushing function, it effectively avoids chip buildup inside the guard and lowers breakdown rate of the protective cover.
Upgraded Hinged Belt Chip Conveyor
Adopts automatic hinged belt chip removal to cut labor cost for manual chip cleaning and downtime loss. The optimized flow design prevents cutting fluid from directly dripping into the water tank; coolant flows into the tank after precise filtration, stopping fine chips from entering and clogging the tank to ease maintenance.
