1) With the most rigid" arch” shape column ,honeycomb type machine bed ,sliding saddle ,worktable and FEA treatment on the machine structure ,the machine is optimized;
2) The standard spindle 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 high revolution accuracy with low vibration and high surface processing.
3) Main spindle transmission has adopted precise C3 accurate ball screw. high positioning accuracy of machine is ensured by triaxial laser-based measuring, ball bar test and μbidirectional pitch compensation.
4) High-strength mechanize casting is dealt with excellent heat treatment ,and super high-frequency quenching guide rails 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 combination machines;
7) Optional configuration forms multi-functional machine tool with flexible module to realize several processing procedure based on one-time tool change, keep up with new trend of international machine tool.
