Abstract
An accumulator tank is mounted on a working head of a replaceable head type machine tool. The tank is connected to each spindle housing on the head to deliver a pressure fluid and jet the same forwardly through the interior of the housing and out an insertion gap surrounding a spindle mounted in the housing. Pressure fluid is supplied to the tank when the head is coupled to a driving unit through respective connecting opening and supply openings. An air jetting opening made in a docking portion of the driving unit to prevent foreign material from lodging therein and blocking entry of a corresponding pin on the working head during coupling can also be the supply opening.
