GA-2000 SUPER HEAVY-DUTY CONSTRUCTION

SUPER HEAVY-DUTY CONSTRUCTION

The low center of gravity heavy-duty bed and 30° slant wedge saddle 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 withstand years and years of rigorous high production turning, the heavily ribbed, one-piece thermally balanced bed and casting components are of " Meehanite " casting.
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.
Precision hand scraped

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.

All spindle and servo motors, including drives, are FANUC alpha i series components to ensure peak machining performance and accuracy.
X and Z axes are driven by over-sized FANUC AC alpha i series absolute servo motors, providing tremendous thrust outputs with faster acceleration and deceleration. Absolute encoder technology eliminates the use of limit switches, thus, eliminating referencing axes to home positions and broken limit switches.

Utilizing the latest 3D CAD design software to assist in machine development, and FEM ( Finite Element Methods ) to provide engineering analysis, we are able to create the best designs possible.

GA series head stocks feature even thickness sides, which evenly distribute cutting forces to the machine bed, resulting in exceptional vibration dampening characteristics and forms a strong structure to handle interrupted and heavy cutting applications. Heat dispensing fins around the headstock evenly dispense heat to reduce deformation, therefore, increase machining accracy.
Slide ways are bonded with " Turcite B " to eliminate stick-slip, minimize wear and maintain long term accuracy. Rapids are 20 m/min. on X-axis & 24 m/min. on Z-axis.
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 precision ground box ways are widely space, and directly cast on to the machine bed and saddle for maximum strength and precision. The box way design also provides the rigidity needed for heavy-duty and interrupted turning applications.
