This machine tool is a special-purpose machine tool for machining cylindrical deep-hole parts. It is suitable for boring cylindrical deep-hole workpieces. During boring, an oil feeder is used to supply oil, and the chips are discharged to the chip hopper at the head of the machine through the cutting zone. During drilling, an internal chip removal method (BTA) is used, that is, an oil feeder supplies oil, and the chips are discharged from the inside of the drill rod to the chip hopper at the rear of the machine through the cutting zone.
Machine tool application: This machine tool is a special-purpose machine tool for machining cylindrical deep-hole parts. It is suitable for boring cylindrical deep-hole workpieces. During boring, an oil feeder is used to supply oil, and the chips are discharged to the chip hopper at the headstock through the cutting zone. During drilling, an internal chip removal method (BTA) is used, that is, an oil feeder supplies oil, and the chips are discharged from the inside of the drill rod to the chip hopper at the rear of the machine through the cutting zone.
The machine tool is PLC controlled, and the reciprocating motion of the oil feeder and feed slide is controlled by servo motors. The transmission uses a rack and pinion drive located in the middle of the two guide rails, ensuring the accuracy and rigidity requirements of the feed transmission during ultra-long movements. Protective features are installed on both sides of the machine bed, and a ground-mounted oil tank structure is adopted, improving the machine tool environment. The machine tool can be equipped with two sets of automatic or manual high-efficiency expanding and contracting tools, greatly improving the machining efficiency.
