The usage of the machine: the machine is a special equipment for drilling and boring deep hole of cylindrical workpieces. While boring, the oil supplied from the oil pressure head take the metal chips from the cutting area to the lantern and chip converyer in the front of the headstock, and drilling adopt internal metal chips remving method (BTA method), the oil supplied from oil pressure head remove the chips from the cutting area to the chips receiver in the back of the machine through the innner hole of the drilling tube. The machine is controled by PLC, and the feed of the oil pressure head and carriage is controled by the servo motor, The feeding rack installed in the middle of the bed guideway guarantee the requirement of feed accuracy and rigidity for the long travel. The protection guard installed on both sides of the bed and overground oil tank improve the working environment. The machine can be mated with automatic or manual telescopic tool so as to improve the machining efficiency greatly. This is a easy operating, high efficiency and environment protective deep hole drilling and boring machine.
