CNC Maximum Performance Turning Centers Casting structure of GS-600L2 model shown

Super Heavy-duty Construction

The low center of gravity heavy-duty bed and 30° slant bed design provide a super rigid foundation for the headstock, turret, and tailstock. Creating the rigidity needed to perform super heavy-duty turning and maintaining long-term high precision accuracy. 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 FC35-Meehanite casting ( industry standard is FC25~30 ). FC35 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.
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.
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 L3 series Z-axis equipped with independent supporting mechanism prevents long-sized ball screws from deforming and ensures excellent performance for the axial feed and turning accuracy.

Utilizing the latest 3D CAD design software to assist in machine development, and FEM to provide engineering analysis, we are able to create the best designs possible.
Contact surfaces of all slides, headstock, turret, tailstock, and ball screw bearing housings with the machine bed are hand scraped to provide maximum assembly precision, structural rigidity, and load distribution.
