摘要

PURPOSE: A spindle with a cutting oil inflow preventing structure is provided to prevent damage to bearings by effectively blocking or discharging cutting oil introduced into the spindle. CONSTITUTION: A spindle with a structure for preventing the inflow of cutting oil comprises a spindle body (110), a labyrinth flange (130), a front cap (140), and a cutting oil inflow preventing part. A bearing (B) is arranged inside the spindle body. The labyrinth flange is a fixing part connected to the spindle body. The front cap is rotationally connected to the labyrinth flange. The cutting oil inflow preventing part is formed in a section where the labyrinth flange and the front cap are coupled.
