  • Patent number: 11143327
    Abstract: A cooling apparatus includes a circulation circuit, a pump, a flow rate adjustment valve, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a stopper that moves between a restriction position and a retraction position. The controller is configured to execute, when maintaining the open degree of the flow rate adjustment, a preparatory process of moving the stopper to the restriction position after arranging the stopper at the retraction position and arranging the valve member further in the valve-closing direction than the stopper through control of the pump discharge amount.

  • Patent number: 11123804
    Abstract: A tool holder for a lathe having a spindle permits improved arrangement of tools on a turret to maximize the allowable workpiece outer diameter for a given tool. A Z-axis feed mechanism moves the spindle and the turret relative to each other in a Z-axis direction along a center axis of the spindle, while an X-axis feed mechanism moves the spindle and the turret relative to each other in an X-axis direction orthogonal to the Z-axis direction. A plurality of tool holders is attached to the turret, each having a tool holding part. At least one of the tool holders holds the tool at a holding position such that, when indexed to a machining position by rotation of the turret, a cutting-edge reference point of the tool is offset with respect to an X-Z plane including a center axis of the turret.
