Description

Technical Field

[0001] The utility model relates to the technical field of annular spray cooling, in particular to an annular spray cooling device for a main shaft of a numerical control machining center. Background Art

[0002] The spindle of a CNC machining center generates a lot of heat when running at high speed. Long-term high-temperature operation will cause deformation and aging of the spindle bearings, motor and spindle itself. The spindle ring spray cooling device sprays cooling lubricant around the spindle to form a fine liquid film, which effectively disperses and reduces the friction and heat between the spindle and the workpiece, thereby reducing the spindle temperature. The spindle ring spray cooling device not only reduces the temperature, but also reduces the wear of the tool and workpiece, making the cutting process smoother, thereby improving processing efficiency.
