Gun drills are basically straight fluted rods that use highly pressurized fluids to achieve cutting into great depth in metal materials. The depth to diameter ratios that can be realized by those specialized tools ranges from 250 to 500.
Around this fluted rod that is essentially the drill, circulates the coolant that keeps drilling temperatures below melting point for both the drill and the workpiece while the chips that are produced from the process flow outside the drilled hole.
Attributes
Gun drill manufacturers pay special attention to the drill tip material as it is the point that receives the most severe fluid pressure. In order for this tip to have prolonged lifetimes and stay free of deformations, it is made out of strong metal alloys or even composite materials.
In order for a gun drill to deliver the required levels of drilling accuracy, everything has to work precisely as intended and the affecting factors must all be carefully calibrated. This suggests for extreme manufacturing quality and the cost is naturally the equivalent. The speed with which gun drill machines can cut through rigid metals such as steel can reach up to 75 cm per minute. This makes up for the increased cost as speed of processing dramatically increases.
Ways Gun Drilling Tools Can Be Applied
Boring Gun Barrels
The most obvious use scenario for the gun drilling machines is for the drilling of gun barrels, which is where this specialized tool got its name from. Gun drills are ideal for the boring of such long holes into rigid metal materials.
The accurate cutting of gun drills makes it possible for very intricate metalwork and produces a smooth finishing on the inner side of the barrel that rarely even needs any polishing at all. This is especially important for guns as bullets that travel at very high speeds could have their trajectory affected by even the slightest deviation.
Molds
Another case that gun drilling machines can come in handy is that of the molds manufacturing. As molten metals have to flow into casting molds through a deep hole, gun drills are used to make that opening.
Tool Making
Some special purposed tools such as the extension fitters found in every toolbox wouldn't be producible without the help of gun drill machines. As these tools are usually made out of chromium and vanadium steel alloys, it is very hard to drill holes in them at high levels of precision. Gun drilling can even achieve polygonal features for torque keys etc.
Musical Instruments
Last, there is the musical instrument industry that requires high precision machinery to achieve certain tonal results out of wind instruments. These can be flutes, clarinets, oboes, saxophones, ocarinas, reeds, bassoons and trumpets, as they all include deep holes of great finishing. Although the soft materials that wind instruments are usually made out of don't require the sheer cutting power of other applications, the cutting precision required can only be met by gun drill machines.
