What is Ejector Drilling Process

        Ejector Drilling Process              Explore Machines with Ejector Drilling capabilities Ejector drilling is similar to BTA deep hole drilling but instead of a single tube, it consists of two tubes Precihole provides reliable, well-designed machines for this process that are guaranteed to perform. Ejector Drilling is similar to BTA Drilling operation with the difference that it has Twin tubes instead of a single tube.The high pressure Coolant is pumped to the cutting face through the annular area between the outer tube and the inner tube. There is a special connector for holding both the tubes and also to feed the high pressure coolant.The pressure head with rear coolant sealing that is required in BTA drilling is eliminated here and only a guide bush is needed.The Chips generated are evacuated through the inner tube where ejection effect is generated at the rear end to help in chip evacuation.The area for chip discharge is comparatively less than BTA and hence the evacuatio
