Machine feathers:

1)the main machine components(machine bed ,sliding sadder ,worktable)have adopted the structure of thermal symmetry and thin-walled mainstock 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.
