Product Description
DEEP HOLE EJECTOR
TWO TUBE BTA Deep Hole Drilling Head -BTA DRILL HEAD
The principle of Ejector drill head chip removal is to press the pressure cutting fluid from the outside of the cutting tool into the cutting area and use the jet suction method for internal chip removal. The arrangement of jet suction drill teeth is beneficial for chip separation. Cutting fluid flows into the connecting sleeve from the inlet, and one-third of it is sprayed from the crescent shaped nozzles around the inner tube
Ejector drill head
Internal tube. Due to the narrow alveolar gap, the jet effect generated by the cutting fluid can create a negative pressure zone inside the inner tube. The other two-thirds of the cutting fluid flows into the cutting area between the inner and outer pipes, and together with the chips, they are sucked into the inner pipe by negative pressure and quickly discharged backwards, enhancing the chip removal effect.
- Compare with single tube BTA, Ejector ones have higher efficiency, Tube with super high strength alloy steel, more stable, especially machining for carbon steel,Alloy steel,Stainless steel.
- Drill head range∶φ25-----φ 200mm
- We do two pipe ejector drill head, at the same time, we make two pipe drill bar with high quality.
Ejector drill head is equipped with a hydraulic system and connecting sleeve, which can be used on lathes, drilling machines, and boring machines. Suitable for medium diameter deep hole machining, with high drilling efficiency.
