Description

Technical Field

[0002] The spindle of a machine tool refers to the axis that drives the workpiece or tool to rotate on the machine tool. The spindle components are usually composed of the spindle, bearings and transmission parts (gears or pulleys). Oil mist lubrication is a new type of centralized lubrication technology. Its principle is to introduce compressed air into the main machine and generate micron-sized oil mist particles through a patented high-tech atomization process. The oil mist flow composed of oil mist particles has good dispersibility and fluidity. It is distributed and transported to the lubrication point. At the lubrication point, the oil mist generates enough vibration and turbulence through the appropriate pressure drop generated by the condensation nozzle, so that there is enough vibration area to produce good condensate, which plays a good lubrication and cooling role.

[0003] During the operation of the existing machine tool spindle lubrication system, a significant problem is that excess lubricating oil often inadvertently drips onto the surface of the machine tool. This phenomenon not only brings potential contamination risks to the machine tool, but also may cause unnecessary waste of resources due to excessive loss of lubricating oil.
