  • Patent number: 10226845
    Abstract: A machine tool capable of facilitating a process of mounting a fluid supplying unit to a spindle supporting unit is provided. The machine tool has a rotating unit including a spindle provided with a workpiece chucking unit, a supporting unit which rotatably supports the spindle around a spindle axis, and a fluid supplying unit removably mounted on a rear end of the supporting unit to allow fluid flow inside the spindle toward the chucking unit. The fluid supplying unit has an insert to be received in the rotating unit in the direction of the spindle axis. A labyrinth clearance is formed between the outer circumferential surface of the insert and the inner circumferential surface of the rotating unit when the fluid supplying unit is mounted on the rear end of the supporting unit.

  • Patent number: 10178910
    Abstract: A drawer apparatus capable of locking and unlocking a drawer without position control and motor stop control is provided. A lock frame is released from the hook to be brought into an operable state by unidirectional rotation of a DC motor in an engaged state. A drawer is released from an anchor to be advanced out of the retracted position when the lock frame operates. A planetary gear unit is pushed by the lock frame. A small-diameter planetary gear is thereby shifted from the engaged state to a default state. The anchor is engaged with the drawer when the advanced drawer is pushed back to the retracted position. The hook is engaged with a lock when the advanced drawer is pushed back to the retracted position.
