MAXIMUM STRENGTH CONSTRUCTION

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-2000 / GS-3000 series is capable of performing super heavy-duty turing and maintain long-term super high-precision accuracy. More rigidity also means extended tool life.
Major structural components have been combined into one solid platform. The low center of gravity 30˚ slant-bed design provides the most rigid foundation possible for the headstock, turret, and tailstock.
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 cast iron is capable of withstanding much greater stress without deforming and provides maximum vibration dampening, which result in a machine that will outlast and outperform the competition.
X and Z axes are driven by over-sized FANUC αi series absolute AC servo motors, providing tremendous thrust outputs with faster acceleration and deceleration. Absolute encoder technology saves time and money by eliminating the use of limit switches, thus, eliminating referencing axes to home positions and replacing broken limit switches.
Contact surfaces of all slides, headstock, turret, tailstock, and ball screw bearing housings with the machine bed are precision hand scraped to provide maximum assembly precision, structural rigidity, and load distribution.
Extra wide hardened and ground box ways are directly formed onto the machine bed and saddle during the casting process. They are precision machine and widely spaced for maximum strength. The box way design also provides the rigidity needed for heavy cutting and interrupted turning applications.
C3 class hardened and precision ground ball screws ensure the highest accuracy and durability possible. Plus, pretension on all axes minimizes thermal distortion.
