BTA Deep Hole Drilling Machine ZK21150*D/1500

The processing employs BTA (internal chip removal) methodology utilizing a FANUC OI Mate TC CNC system. The drill stem operates with rotary and feed motions, controlled by variable frequency speed adjustment. The workpiece spindle features CNC indexing and is lockable during drilling operations. Hydraulically driven guide sleeves, paired with hydraulic clamping mechanisms (including a hydraulic chuck and center frame), facilitate precise drilling of concentric and indexing holes.
