摘要： The invention relates to a machine for drilling and boring tubular plates, the workpiece-carrying elevator being embedded, weight compensation being provided by appropriate means, the machining units moving substantially at ground level opposite thrust tubes bearing on the plate before each machining cycle and absorbing tool thrusts. The machine is characterized by an elevator which supports the plate for machining and which moves on slideways with balancing by hydraulic rams in a constant proportion to the weight of the workpiece being machined. Thrust means retain the thrusts of the spindles, the movements of the latter spindles and means being synchronized by means, the tilting torque produced by the thrust of the spindles is limited by the provision at ground level of a closed framing which interconnects all the constituent elements. The invention is of use for drilling and boring any article, more particularly for the baffle plates of heat exchangers, boilers, water purifiers, heaters and the like.
