Talk about the technical principle of deep hole drilling

The operation of a deep hole drill on an ordinary lathe. The machined part is positioned by the v-shaped iron on the large drag plate of the lathe and clamped with bolts. When drilling and processing, the drill pipe is clamped by the exclusive chuck in the spindle and rotated by the spindle, and the parts are driven by the big drag plate for feeding movement. The hydraulic feeder is installed on the operating table of the machine tool and is sealed with the left end face of the parts by the o-ring.




The pressurized cutting fluid is injected through the inlet of the liquid feeder and flows into the cutting area through the gap between the outer diameter of the drill pipe and the wall of the hole. The cutting tool is operated and cooled. The chip, along with the cutting fluid, is discharged from the drain box through the outlet of the exclusive chuck in the drill pipe inner hole. Cutting fluid can be 5% emulsion; Cutting parameters can be selected as V=60~90m/min, S=0.035~ 0.23mm /r. Because the drill pipe is long and thin, it is easy to be deformed, so the movable center support is installed on the guide rail of the machine tool, and the support can be operated at any position of the drill pipe. The liquid feeder is connected with the large towing plate by a coupling plate, and the feeding movement is made together with the parts.




Deep hole drill is the workpieces by particular of cone top of spindle box and chip set, bit by drill pipe box brought about high-speed cutting motion, servo motor drives the ball screw drive drill pipe box to realize feed movement, oiler will grant high pressure cooling oil injection, from the bit back from the drill hole cutting position of the direct artifacts, drilling cuttings by chip cooling fluid along the drill guide groove rushed to the chip set, enter the chip set, cooling fluid magnetic filtered by the filter paper and to continue to use the tank. The chip removal process is the guide sleeve jacking the workpiece when drilling, which not only plays a guiding role, but also prevents the leakage of high-pressure coolant, which enters through the special drill hole and reaches the cutting edge.
