Gun drills are a special kind of drills that use highly compressed air or other suitable fluids to cut into deep holes of depth to diameter ratios that surpasses 400. These drills don't have helical features like the classic drills, but instead they feature a hardened tip on the front that is where the fluid comes out of and hits the cutting face.
Featuring a fluted rod design, the drill is kept under melting operating temperatures thanks to a circulating coolant that also helps with the removal of the cut material chips. The fluids move through the rod itself, while its pressure is controlled by the machine operator and the main pump.
Features
The most important part of a gun drill is its tip, as this is the point that is called to sustain the tremendous pressure of the effused fluids. For this reason, the tips are made out of hardened metal alloys and aerospace-grade composite materials. This prolongs their service life and ensures that no catastrophic deformations will take place.
There is no other type of drill that can compete with the astonishing cutting rates achieved by gun drills. At high speed modes, quality gun drills can bore steel metals at a rate of 75 cm per minute or more. This is combined with unparalleled cutting accuracy that produces cuts of perfect surface finishing that normally won't need any hand polishing in most cases.
Applications
Gun Barrels
The name of the gun drills derives from their main and most prominent use case that is the boring of gun barrels. Gun barrels were made using the metal casting technique before gun drills were made available showing much less durability and resistance to explosive forces.
Gun drilling machines are ideal for the particular application as the perfect finishing of the inner surface of the gun barrel ensures the unobstructed and unaffected trajectory of projectiles. Moreover, the accuracy of the cuts ensures coherent barrel thickness which subsequently means homogeneous heating and thus less cracks and longer lifetimes.
Molds and Dies
Another application that calls for the unique abilities of the gun drilling machines is the manufacturing of molds that are used for the production of heavy duty metal parts or large tools. The gun drill can help bore a deep hole through which the molten alloys can be inserted into the casting area.
Tool Manufacturing
A popular application for gun drills is tool manufacturing. There are several types of mechanical tools that feature deep holes that serve as fitting positions for extensions etc. Deep hole drilling machines can help boring the hardened alloys that tools are made of and can even achieve polygonal features.
Making Musical Instruments
Last, gun drilling machines are extensively used in the music instrument manufacturing industry and especially for wind instruments that require deep holes of small diameter. These instruments can be flutes, oboes, bassoons, saxophones, clarinets, trumpets, ocarinas and reeds. As most of these instruments are made out of brass and other soft metals, gun drill machines are required to work with precision and delicacy as the slightest deformation will result in wrong tonal performance.
