 MEEHANITE high quality casting iron assures permanent and accuracy. Each Akira Seiki casting frame is verified when founded by the autherized Mehanite casting follows each Akira Seiki machine. The Certificate of Mehanite casting follows each each Akira Seiki machine. |
 |
The spindle is designed for high speed rotation in excellent low inertia and well balance that acts efficient acceleration and ever lasting cutting rigidity. |
 |
The perfect chilling system minimizes the constant temperature of spindle and coolant supply to wide head cartridge area to prevent deformation during cutting period. |
 |
Least friction coefficient and preloading for clearance-free between moving surface, precise ball linear guide ways are most compatible for fast movement and high positioning & repeatability accuracy. |
 |
To optimize combination with JR/SR rigid machine center, Akira Mi745 coordinates the CNC digital control and world leader drive system. High resolution servo stabilizes precise axis positioning for high complex and accuracy jobs. Absolute industrial control components ensure reliable longevity and instant technical support in worldwide service centers. |
