Deep Hole Drilling BTA Machine Deep Hole Gundrilling Machine

  TECHNICAL SPECIFICATIONSGun drilling and BTA Combined drilling machine (Model: ZK2108Fx2×2500mm )Machine Operation: BTA Method (Internal chip removal ) , Gun drilling method (External chip removal). These two processing methodcannot be used at the same time.  Machine Specifications:  Technical ItemsParametersGun drilling diameter rangeΦ4mm~φ30mmBTA drilling diameter rangeφ25mm~φ80mmMax.Hole drilling depth2500mmMax.workpiece Length2500mmWorkpiece OD rangeΦ50~Φ200mmCNC control system:GSK systemMachine brief:  The machine adopts horizontal layout, using gun drill (External chip removal) and BTA (Internal chip removal) two processing methods, the two processing methods can not be used at the same time. For example, when using gun drill, BTA can not be used; workpiece is clamped on the machine by chuck and cone disc;cutter tool and workpiece rotate relatively, and cutter tool feed.When the gun drill and BTA are converted, it is necessary to change the cutter, auxiliary tools and oil circuit manually, so that the conversion of the two processing modes can be realized.The machine adopts double spindle structure. The gun drilling drill box and BTA drill box are assembled on one bracket and share one infeed system.Machine features:It has two processing methods: gun drill (external chip removal) and BTA (internal chipremoval). Double spindle structure, one spindle for gun drilling, the other spindle for BTAprocessing.Bed body, box body, worktable and other basic parts are cast with high quality cast iron.Equipped with special cooling system: composed of automatic chip conveyor, oil cooler, filtersystem, high-pressure pump group, etc.Z-axis feeding guide is double rectangular sliding guide with good rigidity.The spindle motor is used to drive the cutter tool rotation, and the feed of the tool is realized by the ball screw driven by the servo motor. Stepless speed regulation can be realized by rotating and feeding thecutter.Electrical system: it was controlled by CNC system, which can not only program and set up the automatic processing cycle, but also can adjust manually, point, start and close.The machine has the functions of pressure protection, liquid level and temperature protection of cooling system, tool protection and stroke protection.Machine mainly Parameters:SpecificationParametersNoteWorking capacityDrilling diameter rangeGun drillingΦ4~Φ30mm BTAΦ25~Φ80mmMax.drilling depth2500mm Max.workpiece length2500mm Workpiece OD rangeΦ50~Φ200mm MachineDrillboxforGunMax.rotary speed10000r/minSteplessperformancedrillingMain motor power7.5KWSpindle motorDrill box for BTAMax.rotary speed2000r/minSteplessMain motor power30KWSpindle motorZ axisInfeed speed range5~500mm/minSteplessRapid traverse rate2000mm/min Motor torque23Nm OthersMax.hole-Length ratio100:1 Machine total powe(r  roughly)70kW Machine floor space(roughly)9m(L)×3.4m(W) Machine total weight(roughly)15T CNC systemGSKCooling systemMax.PressureGun drilling10MPa BTA5 MPa Max.flowGun drilling100L/min BTA300 L/min Filtering accuracy40μm   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
