GA-2000/600 Super Heavy-duty Construction

Compact And Highly Rigid Structures

All the main casting components are structural analyzed by Visual Nastran finite element methods ( FEM ). The boundary conditions are assigned reasonably and adequately to optimize the structures and rib distribution of the base, saddle and headstock to reach high rigidity and better stability. The headstock is mounted on the same surface of the 30 degrees slanted guide ways. This design shortens the transmission path of cutting force and stabilizes the cuting capability.

X and Z axes are driven by over-sized FANUC / MITSUBISHI 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.
High precision hardened and ground box ways are directly formed onto the machine bed and saddle during the casting process. They are precision machined and widely spaced for maximum strength. The box way design also provide the rigidity needed for heavy duty and interrupted turning applications.
Slide ways

Slide ways are bonded with “Turcite B” to eliminate stick-slip, minimize wear and maintain long term accuracy. Rapids are 24 m/min. on X & Z-axis.

Highest accuracy and durability

C3 class hardened and precision ground ball screws ensure the highest accuracy and possible. Plus, pretension on all axes minimizes thermal distortion.

Precision hand scraped

Contact surfaces of all slides , headstock and ball screw bearing housings with the machine bed are precision hand scraped to provide maximum assembly precision, structural rigidity, and load distribution.
