摘要： A spindle device includes a cover member. The cover member has, formed therein, a gas flow path configured to flow a compressed gas for providing sealing between a chuck portion as a rotating member and the cover member and sealing between the chuck portion and the spindle housing. The gas flow path includes a first conduit configured to communicate the outside of the cover member and a second conduit configured to allow the first conduit to communicate with a gap between the chuck portion and the spindle housing, the second conduit being larger than the outlet of the first conduit. The outlet of the second conduit faces a surface of the spindle housing.

摘要： In a tool changer configured so that a turret is turned to index a desired tool to be changed, the front and rear surfaces of the turret are covered individually by covers. These covers are each formed in the shape of a truncated cone. Chips and a cutting fluid dropped onto an upper part of the cover that covers the rear surface of the turret flow away from a gap between the covers along a slope of the cover concerned, so that they can be prevented from getting into the turret through the gap.

摘要： A liquid drainage mechanism drains oil (liquid) from a Y-axis slider that moves along a predetermined path. The liquid drainage mechanism includes an outflow hole and a nozzle flow passage that are provided in a C-axis rotary mechanism and configured to flow the oil in a stator, a nozzle configured to move integrally with the Y-axis slider and discharge the oil, and a Y-axis guide member configured to guide the Y-axis slider. The nozzle is disposed at a position that is close to but not in contact with the Y-axis guide member, and the nozzle discharges the oil so that the oil reaches the Y-axis guide member.
