Gun drills are the most accurate, fast and capable type of drills that manage to cut deep holes on metal materials through a controlled release of highly compressed fluids. Those drills are the only ones that can bore holes of depth to diameter ratios of about 350.
These rods have a hole on their front hardened tip from which the fluid flows at high enough speeds to cut strong materials with remarkable accuracy. The chips that are produced by the cutting process are removed through the use of coolants that also flow inside the bored hole. This also helps keep the drilling temperatures at a lower than melting level.
Characteristics
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.
The speed of gun drill machines is one of the strongest characteristics of this tool as high speed drills can bore steel at a rate of 75 cm per minute or even more depending on the diameter. The most significant advantage of deep hole drilling machines, though, is the extreme accuracy with which they can cut through hardened metals. These tools can achieve an astonishing finishing that rarely needs further polishing.
Ways Gun Drilling Tools Can Be Applied
Boring 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.
The smoothness of the gun barrel's inner surface that only gun drills can achieve ensures that the projectiles will travel straight inside the barrel. The accuracy of the gun drills guarantees the homogeneous heating of the barrel, durability to explosive forces and long lifetimes. Before gun drilling machines were available, casting was used for the production of gun barrels.
Molds
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.
Manufacturing Tools
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.
