  • &nnsp;

    &nnsp;

    The TONGDA novel high-speed and high-performance spindle adopts innovated designs of HPS-68 insert incorporating both a roller neck bearing and a sphero-point (convex) footstep bearing, the convex footstep bearing consisting of a radial bearing which functions hydrodynamically and an axial plane-thrust bearing to absorb the axial forces, the diameter of the neck bearing being reduced to 06.8mm, the distance between the neck bearing and the footstep bearing being reduced to 100mm, and further reduction of the wharve diameter, and etc., has been granted a lot of patents for our technologies.

  • &nnsp;

    &nnsp;

    Compared with the conventional common spindle incorporating the cone-point (conical tip, pointed) footstep bearing, such innovated designs naturally have the structural advantages of stable operation, no axial displacement, less friction wear, high load supporting capability, better consistency, etc.

  • &nnsp;

    &nnsp;

    Tongda group has further developed the excellent performances of these genes by means of advanced and applicable technologies.
