GA-2000 高剛性結構


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.
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.
X and Z axes are driven by over-sized FANUC AC αi 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.
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.
C3 class hardened and precision ground ball screws ensure the highest accuracy and durability possible. Plus, pretension on all axes minimizes thermal distortion.
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.
GA box way
GA hand scraping
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.
