1. One time clamping left and right box each 1 piece, multi-axis, multi-directional and multi-processing mode at the same time;
2. Rigid multi-axis box bearing chamber position ≤ ± 0.01mm;
3. High stability. The dowel hole of precision bearing system Cpk>1.67, other finishing hole system Cpk>1.33;
4. Using variable frequency drive for spindle, servo drive for feed, so cutting parameters can be flexibly adjusted;
5. Easy operation and maintenance;
6. In accord with national industry standards.
