seal clearance Strong liquid film.It is filled in securely in rotation gap, and cutting fluid is prevented to flow out in rotation gap.In the left survey of liquid film, There is a small amount of cutting fluid to be precipitated from liquid film, into the gap of cooling tube core 22 and axis of cone inner sleeve 29.On cooling tube core 22 If 8 holes, the electro spindle 11 for making leakage fluid quickly enter pressure atmospheric pressure is external, has reached sealing effect, guarantees electro spindle 11 can normally work.Headstock of the invention uses hydrostatic bearing pattern.In order to improve the machining accuracy and static pressure axis of lathe The stability held.The present invention increases the microstoning of bearing support circle in the processing of head of a bed axis.It has manufactured thus special special With lathe, head of a bed axis carries out attrition process after high fine ginding, to head of a bed axis.After to be ground, the circularity of head of a bed main shaft is by original 1.5 μm be increased to 0.3 μm.Head of a bed axis precision improves, when not only improving the dynamic balancing of head of a bed axis, while further improving work The aqueous agitation of fluid bearing reduces the concussion of hydrostatic spindle 8.The raising of simultaneous processing circularity keeps static pressure film more uniform, And the oil cooling system for increasing freon refrigeration improves the rigidity and stability of hydrostatic bearing.It is final to improve static pressure master The running accuracy of axis 8 improves the machining accuracy of lathe.Present invention employs high-precision roller guide, high precision ball lead screw, And realize digital control, improve the kinematic accuracy and positioning accuracy of lower slide unit 5.Hydrostatic bearing main shaft 8 is added using superfinishing Work improves the rigidity and rotating accuracy of hydrostatic bearing, and electro spindle 11 uses hollow cooling, improves 11 revolving speed of electro spindle, changes It has been apt to cutting effect, has improved cutting speed and cutting system rigidity, improve the cutting precision of lathe, effectively reached mesoporous For circularity grinding accuracy up to 0.2 μm, seat surface circularity grinding accuracy has been more than domestic similar up to 0.4 μm of high-precision grinding effect The machining accuracy of lathe, the machining accuracy for having reached import lathe are horizontal.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
