Gun Drilling...what is it?
First introduced in Europe over two centuries ago, the process was born out of the need to generate the bore of gun barrels in a more efficient manner. Gun drilling allowed the tool to drill the full length of the barrel without retraction by injecting cutting oil through the hollow shank of the gun drill. Once the oil had lubricated the cutting edges of the tip it escaped along the vee-shaped flute of the shank, taking with it the chips.
Gun Drilling...How has it developed?
As with any new process, gun drilling underwent constant development as related technologies evolved. The most significant improvements in the early stages were development of the high pressure pump and the debut of sintered carbide. With the switch to carbide tips and high pressure coolant, the process was able to yield faster cycle times and better finishes. Improvements continued as experimentation showed that by varying tip geometries, certain materials and conditions could be better accommodated.
