1)With the most rigid" arch" shape column, honeycomb type machine bed, slidding saddle, worktable and FEA treatment on the machine structure, the machine is optimized;
2)The standard spinle speed is 8000rpm and the optional speed is 10000-15000rpm. High speed accurate main speed is driven by high speed belt with gear. Secondary dynamic balance inspection is done on main spindle, resulting in a high revolution accuracy with low vibration and high sureface processing.
3)Main spinle transmission has adopted precise C3 accurate ballscrew. High positioning accuracy of machine is ensured by triaxial laser-based measuring, ball bar test and μ Bidirectional pitch compensation.
4)High-strength meehannite casting is delt with excellent heat treatment, and super high-frequency quenching guideways are treated with delicate grinding and scraping;
5)The machine can be optionally equipped with gearbox with gear ratio 1: 2/1: 4/1: 8, which help to select right spindle according to requirements and to improve productivity and lower investment cost;
6)The machine can be equipped with multi-axial boring and multi-axial drilling spindle box to achieve effective processing with multi-cutter and multi-spindle, which reflect innovative integration of machining center with advanced technology of combinated machines;
