Ejector Drilling Process



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 evacuation is not as efficient particularly in smaller sizes.Since the tube diameter is larger than BTA Drilling the torsional strength also goes up. This can be an advantage to go for higher feeds. This is usually used to retrofit conventional machines for deep hole drilling.

Gun Drilling | Gun Drilling Process| - Precihole Machine Tools

Gun drilling process is used to produce deep and straight holes. This process is very specialized as compared to the conventional twist drilling process . The standard gun drill tool geometry has a single effective cutting edge. Unlike the twist drill, the gun drill cuts through the metal eccentrically, and once inside the component, the tool self-pilots itself. The hole is further burnished due to the guide pads which finally result in a precise round hole with maintained straightness. The Coolant enters the tool through the coolant through-hole and the chips are gushed out through the V-shaped profile on the gun drill. Gun Drilling is effective from ф1 to ф30, but if you wish to go higher BTA drilling becomes more effective than gun drilling.
