HIGH RIGIDITY CONSTRUCTION

The low center of gravity heavy duty slant bed design provide a super rigid foundation for the headstock, turret, and tailstock.
By using Finite Element Methods ( FEM ), optimal reinforce ribbings are directly cast into the one-piece bed structure. Mechanical rigidity has been increased by more than 30 % when compared to conventional designs. The GS-8000 series can provide both heavy cutting and high precision capabilities. More rigidity also means extended tool life.
Built to endure years and years of rigorous high production turning, the heavily ribbed, one-piece thermally balanced bed and casting components are of MEEHANITE casting.
MEEHANITE grade cast iron is capable of withstanding much greater stress without deforming and provides maximum vibration damping, which result in a machine that will outlast and outperform the competition.
All spindle and servo motors, including drives, are FANUC alpha i series components to ensure peak machining performance and accuracy.
C3 class hardened and precision ground ball screws ensure the highest accuracy and durability possible. Plus, pretension on all axes minimizes thermal distortion.
Extra wide hardened and ground box ways are directly formed into the machine bed and saddle during the casting process. They are precision machined and widely spaced for maximum strength. The box way design also provides the rigidity needed for heavy duty and interrupted turning applications.
The oil mist system can evenly and efficiently lubricate the spindle bearings to prevent thermal expansion while ensuring machining accuracy.
