Rigid Structure
One-piece slant bed structure
Machine bed is made of one-piece high-grade Meehanite casting to allow heavy cutting capabilities. Wide hardened and ground box ways are coated with Turcite and hand-scraped for ultra-precise fitting to reduce vibration while offering better tool life and surface finishes.
Axis structure is directly driven by precision ballscrew and powered by AC servo motor for smooth movement with virtually no backlash.

Built-in motor driven spindle
Thermally symmetrical design on the head stock diminishes distortion and provides stable accuracy on work pieces even in continuous high speed machining.
Spindle is supported by a double row of tapered roller bearings in the front and rear of the spindle toresist axial cutting force, while self-alignment angular contact bearings provide tremendous radial load capability.

Main and sub spindle synchronization
Both the main and sub spindle, C1 and C2 axes provide positioning resolution up to 0.005 degree.
Accomplish three dimensional contouring. combine round amd prismatic machining by harmonized control of the spindles with the X and Z axes.  
Synchronization between main and sub spindle at any rotation speed can be programmed to perform part transfer for secondary machining, enhancing production efficiency and reducing idle time.

Turret
The fast 12-station BMT servo-mechanical dodecagonal drum turret, featuring a large 3-piece curvic coupling and powerful hydraulic clamping force, assures unparalleled rigidity in all machining conditions.
Live tool holders can be mounted on all 12 stations, but only the working position is driven.
VDI live tool turret is also available as an option upon request.

Stable axial system
The axial direction adopts high-precision ballscrew and high-precision bearing design, effectively eliminating backlash and thermal elongation displacement provide stable and high CP value finished parts.
Y-axis adopts 30-degree sliding seat virtual composite structure with high rigidity the best Y-axis mechanism with stability.
The axial sliding surface is attached to the Turcite wear piece and applied to the high shovel the scraping operation can maintain the characteristics of long-term smooth motion accuracy.

Programmable tailstock
The whole multi-tasking series equip with programmable tailstock as standard, the positioning of the tailstock body and the expansion and contraction of the quill both can be controlled by the program
Saddle and tailstock can be adjusted separately or driven at the same time and driven to the desired position

Aesthetic design
Simple and atmospheric appearance sheet metal design
Fully enclosed sheet metal design, with particular emphasis on water and chip protection
