1)the main machine components(machine bed, sliding saddle, worktable)have adopted the structure of thermal symmetry and thin-walled main stock with multi-layer ribs. Arch" shape column with high rigidity goes through optimized treatment by finite element analysis to guarantee the best rigidity;
2)the adoption of C3 grade precise ball screws and the use of special bearing on the ball screw with pre-pull treatment as well as laser detective compensation have ensured the rigidity and precision.
3)The main base parts of machine are made from high-grade, high quality gray casting iron with aging treatment, the guide rails with high-frequency quenching treatment and delicate grinding, covered with low frictional coefficient TURCITE-B and dealt with delicate scraping, having effectively improved motional quality of machine and necessary touching rigidity for cutting.
4)The adoption of balance weight block with motion-based device has prevented the spindle form vibration when weight-balanced block moves up and down, avoiding influencing the processing accuracy.
