One-Piece Casting Bed

One-piece 30-degree slant bed made out of Meehanite cast iron, which has superb vibration absorption characteristics, provides rigid foundation for all machine components. Such design endures long-term machining accuracy and consistency. In addition, 30-degree slant bed design provides operators with convenient access to the workpiece and superb chip discharge.

High-Precision Hand Scraping

The full-contact precision hand scraping of all core mating surfaces ensures exceptional anti-vibration performance and consistent cutting precision even under heavy load conditions.This high-precision scraping process greatly reduces long-term frictional wear of all moving parts, maintaining the machine’s original factory accuracy for years of continuous production.

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

High-rigidity cast iron worktable with standard T-slots for flexible workpiece clamping. Combined with three-axis box-way layout, it features superior load capacity, enhanced motion stability and effectively minimizes machining deformation under heavy loads.
Three-axis servo motors are directly coupled to high-precision ball screws via flexible couplings, eliminating intermediate transmission links for backlash-free drive. The optimized main support structure reliably carries all transmission components, ensuring stable high-speed operation even under heavy cutting conditions. It reduces auxiliary time and significantly boosts overall machining productivity.

 

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.
