IPC: B24B55/06
Filed: 2022-04-19
Abstract: To provide a spindle unit capable of reducing a frequency of cleaning a tip of a spindle by suppressing adhesion of treated liquid containing treatment wastes to the tip.SOLUTION: A groove is formed around a spindle in a region opposite an inner surface of a cover of a side surface of a tip of the spindle via a gap. At a place where the groove is formed, a sectional area of the gap between the tip of the spindle and the cover is enlarged. Thus, the gap between the tip of the spindle and the cover can be a space in which spaces (flow paths) small in the sectional area and spaces (expansion rooms) large in the sectional area are alternately arranged. In this case, even when treated liquid containing treatment wastes enters into the gap between the tip of the spindle and the cover, entry of the treated liquid to the flow path provided at a depth of the expansion rooms becomes difficult. Thus, adhesion of the treated liquid containing the treatment wastes to the tip of the spindle is suppressed, and a frequency of cleaning the tip can be reduced.SELECTED DRAWING: Figure 3
