<p>MACHINE TOOL COOLANT SYSTEM A coolant system for a machine tool is disclosed. Sockets on the machine tool are equipped with check valves biased to a closed position. When a tool is inserted into a socket, an actuating member opens the check valve to enable coolant to flow through a conduit in the tool to the cutting edge of the tool. Tools whose cutting edges do not require coolant are not equipped with the actuating member. In addition, a distributor is provided for use in the coolant system of a machine tool having a turret. The distributor is mounted on the turret and is coaxial with the axis of rotation of the turret. Coolant is piped into the center of a distributing member having an outlet on a cylindrical side surface. A receiving member has a cylindrical chamber in which the distributing member is rotatably disposed. The receiving member has a plurality of radially disposed passages which lead from the receiving member to the tool receiving sockets on the turret. Coolant flows only to a tool in the working position because only the passage leading to that tool is aligned with the outlet of the distributing member. As the turret is rotated to index a different tool to the working position, coolant is ported to the passage leading to the tool then in the working position.</p> |
