Batch Processing Gun Barrels with Inovatec
Pistol barrels can be made from a variety of metals: alloy steels, aluminum, stainless steel, carbon fiber, and so on. Properly finishing pistol barrels is very important because it determines the efficiency and the appearance of the barrel.
As pistol barrels are not the biggest of the bunch, you can easily process them in a vibratory finishing machine or a centrifugal disc finisher. You don’t necessarily need a tub vibratory machine.
A gun barrel blank is one of the most important components of a rifle or any other gun. The accuracy of the final product heavily depends on the precision of the machining. Then the blank itself will be machined to form the actual barrel.
These gun barrel blanks are usually long metal parts. There is no other alternative to accurately process long parts other than in a tub vibratory finishing machine.
In almost all cases, a double-barrel shotgun barrel would be made of alloy steel. It’s either reamed, drilled, or forged. Whichever it is, it needs some heavy polishing before getting hooked to the shotgun itself.
It’s obvious that shotgun barrels are pretty long so you’d have to go for the tub vibratory finishing machine. Inovatec has the best tub vibratory finishers available for you.
There’s not much difference in the polishing method when it comes to gun barrels. The AR15 gun barrels are quite long just like the double-barrel shotgun. So, you’ll need a tub vibratory finishing machine that Inovatec can provide for you.
Think about the gun barrel blanks. The blanks are then further polished to form the final rifle barrels. As it goes for longer metal parts, get the tub vibratory finishing machine from Inovatec.
If there is one gun in the world that is more popular than the others, it would be the AK47. This legendary gun has proved it’s worth and what it can numerous times. And part of its awesomeness comes from the proper finishing.
Just get a tub vibratory finisher from Inovatec and the right media if you’re into the business of polishing AK47 gun barrels.
Media for Polishing Gun Barrels

1. What Is a Gun Barrel?
A gun barrel is an essential part of a gun or rifle.
It is basically a tube that is in the front part of a gun.
A high expansion of high-pressure gases happens inside this gun barrel.
Thus, it pushes out the projectile in front with a high velocity.
2. Why Polish Gun Barrel?
Let us have a look at the various benefits of polishing gun barrel parts.
2.1 For Best Appearance
The barrel part of the gun quickly draws the viewer’s attention. So, you need to ensure that they are in the best shape.
You can achieve the best possible appearance only through proper finishing and polishing.
2.2 For Accuracy
The front end of the gun barrel is called the muzzle.
It is the last point of contact for the projectile before the release.
So, you need to ensure that there are no irregularities in the muzzle surface.
Otherwise, it can affect the trajectory of the projectile. So, accuracy may get compromised.
So, you need to ensure that the muzzle is finished and polished correctly.
2.3 For Symmetry
You need to ensure that the gun barrel has the right symmetry for the proper working of the gun.
Otherwise, the projectile will miss the target, even if you have a good aim. Polishing helps to maintain the barrel symmetry.
2.4 Strengthens the Part
A weak gun barrel can prove to be disastrous.
So, you need to ensure that the part is sufficiently strong.
Manufacturing of gun barrels may result in marks and pits on the metal surface.
These are weak spots.
So, you need to remove them before assembling the gun through the finishing and polishing process.
2.5 To Prepare the Gun Barrel for Bluing
Bluing is the process of creating a thin layer of coating on the gun barrel surface.
It applies to steel gun barrels. Here, the red iron oxide is converted to blue-black iron oxide.
Polishing gun barrel for bluing is essential to ensure that the coating is uniform across the surface.
Otherwise, the protecting layer will not be effective.
2.6 To Resist Oxidation & Tarnishing
There is a tendency for the metal surface of the gun barrel to get oxidized.
It happens when it is exposed to moisture. It will tarnish the gun barrel.
A proper finishing and polishing ensure that the oxidation effect is kept to a minimum.
3. What Is the Traditional Way of Polishing Gun Barrel Parts?
The traditional method of polishing gun barrel parts is a mechanical process.
It makes use of the wheel grinding technique. There are two ways of doing it.
In the first method, the grinding wheel is stationary.
It is fixed to an immovable surface.
You need to switch on the wheel and move the barrel surface along the edge of the wheel.
Thus, the wheel polishes the gun barrel.
There will be multiple wheel heads of different abrasive strengths.
You need to use these heads to get the desired finish.
In the other method, the gun barrel is made stationary.
Here, the person needs to move the wheel grinder along the barrel surface for polishing.
4. What Is a Gun Barrel Polishing Machine?
A machine that is capable of finishing and polishing gunmetal barrel surface is called a gun barrel polishing machine.
The whole process of cleaning, finishing, and polishing happens automatically.
The person operating the machine has to load the machine with the gun barrel parts and the cleaning media.
The time duration for polishing varies for different machines. It also depends on your final finish quality.
