These machines use magnetic pins to clean the cases. It’s even possible to clean the inside the brass cases. Invest in such a machine if you’re goal is an absolute polish of the parts. It can remove the oxidation layer of the parts.

Brass Case Polishing Applications

Annealing is the process of softening the tip of the brass cases for more accuracy. These cases have two different hardness properties. So, it’s very delicate to polish them.

To polish the annealing brass cases, it’s best that you go with a vibratory tumbler. The curved wall is great at compensating for the difference in hardness.

Pistol bullets have a brass casing that holds the gunpowder. It’s crucial to polish the brass cases for maximum accuracy. The pistol ammo cases are very small in size so you need to keep it in mind.

For small parts like pistol ammo casing, you can either use a vibratory tumbler or the magnetic tumbler machine. If you use stainless steel pins, you can clean the inside of the cases as well.

Rifle ammo is slightly bigger than pistol ammo. They’re less complex to polish with a bass case polishing machine. They might or might not go through the annealing process.

A regular vibratory finishing machine will do the polishing just fine. If you want to take the finishing process one step further, you can invest in a magnetic tumbler machine.

This ammo is the regular brass casings but with a nickel plating on top. The plating process makes the surface uneven. So, you need to polish these cases twice. Once before the nickel plating and once after.

As the nickel plating is very thin, precision is required. It’s best to go with the magnetic tumbling machine. These machines use precision media like stainless steel pins.

Brass case polishing for Smith Carbine cartridges are very similar to rifle ammo case polishing. The Smith Carbine ones are a little bigger than the rifle ones.

Use a regular vibratory finishing machine or a vibratory tumbler from Inovatec to get the best results. Just make sure that you are using the right media.

The head of the bullets is made of various materials like lead, alloy or brass. It’s very important to polish the bullets thoroughly to get the maximum precision out of them.

To polish the bullet lead, use a regular vibratory solution as your brass case polishing machine.

Brass Case Polishing Media

Stainless steel is the best media to polish brass. Brass is a soft metal so you need to use stainless steel pins for best results. You can also use corb cob media or walnut shell grit for brass case polishing as well.

1. How can I clean my brass cases using a vibratory tumbler?

Now, cleaning your brass cases using a vibratory tumbler is not tricky, and it can be economically feasible.

 

Check this out:

Vibratory tumblers are one of the most outstanding machines that you can use to polish your brass casings.

All you need to have is the machine itself and walnut shell grit or corn cob grit tumbling media.

You’ll also have to acquire a polishing compound.

 

These tumbling media are organic, and they absorb impurities exceptionally well.

The vibratory tumbler has enough space to cater to the mass finishing of these brass casings together with polishing media and polishing compounds.

The vibratory tumbler works by vigorously shaking its tub (bowl) to create the tumbling effect.

It has an immensely robust motor.

Using polishing compounds is so popular nowadays, compared to dry polishing.

The polishing compound enhances the polishing quality and process.

When using such compounds, the process shouldn’t take long to complete.

After the process is complete, you’ll have to thoroughly rinse your brass casings with water to get rid of the compounds used.

After that, you’ll need to dry the brass casings – get rid of the excess water.

Industrial vibratory tumbler

 

You can decide to use a more straightforward way – using a towel and the sun to dry your cases.

However, this method leaves your cases exposed to air, and the end product may not be as shiny as you anticipate.

The other way is by using a vibratory dryer. The dryer can use up to a maximum of 15 minutes to dry your brass casings en masse.

Drying helps to curb tarnishing. Tarnishing is brought about by water.

 

2. What is the best media for polishing my brass cases using a vibratory tumbler?

When using a vibratory tumbler, the best polishing media is an organic media.

Two kinds of organic media can be used to polish brass casings.

The first one is called the corn cob grit tumbling media. It is used to polish as well as absorbing impurities on the surfaces of brass cases.

The second one is called the walnut shell grit, which is also used for the same purpose as corn cob grit.

However, walnut shell grit is more rigid compared to corn cob grit, which makes it an ideal polishing media for brass casings.

Brass is a softer metal, and that is why robust media like ceramic media is not commonly used.

When cleaning brass casings, you do not want them dented, because dents will make reloading difficult.

You can use a vibratory tumbler to anneal (soften the tip of your brass for more accuracy), where these cases have two distinct rigid properties.

Also, a vibratory tumbler will help you clean both brass ammo pistol cases and brass rifle case polishing.

 

3. Can brass cases be polished using a rotary tumbler?

When polishing brass cases, it would be ideal for carrying out the process using a vibratory tumbler.

Using a rotary tumbler can be tricky, and it can damage your casings because they tumble on each other

When there is a lot of part-to-part contacts, dents may be formed in your brass casings.

Dents will make reloading harder, and it will provide less accuracy.

Dry polishing is not so popular nowadays.

Using compounds to polish your brass casings would be most appropriate, and it will take a lesser amount of time.

 

5. How long should I polish my brass cases using a vibratory tumbler?

Well, cleaning your cartridge cases using a vibratory tumbler should not take a lot of time.

The process needs to take minutes and a maximum of a few hours.

When using a vibratory tumbler, the machine shakes its tub in a way that it ensures your brass casing is polished even on the most intricate corners.

The good thing with using a vibratory tumbler to polish is that it maintains the shape of your brass case.

Extending the polishing process for some minutes will not damage your cartridge cases. However, it will be uneconomical for you.

When polishing, you have to aim for efficiency, effectiveness, and economic feasibility.

 

6. Can I polish brass cases using a magnetic tumbler?

Yes, your bullet shell can be cleaned using a magnetic tumbler. The magnetic tumbler finishes polishing in a short time.

The magnetic tumbler uses electromagnetic principles to complete the polishing process.

The machine can be found in different sizes, that is, the desktop magnetic tumbler size and the big industrial size.

The primary factor that you’ll need to consider when using your magnetic tumbler is its optimum capacity of polishing.

The industrial magnetic tumbler has a capacity of up to 10kgs.

These are a lot of bullet shells.

However, for the desktop version, things are a bit different.

The desktop magnetic tumbler is a bit lighter than the industrial one and can polish up to 1.3 kilograms of cartridge cases.

The magnetic tumbler is a very robust machine, and it cleans your brass cases spotlessly and efficiently.

When using the magnetic polishing machine, the media cleans the most intricate corners to ensure accuracy and easy reloading is achievable.

The magnetic polishing machine cleans your pieces faster than the vibratory tumbler.

The process can run for some minutes or a few hours, depending on your degree of polishing that you desire.

The time taken to complete the process is also determined by the speed set when the process is in play.

 

7. What media is used for magnetic polishing of brass cases?

When polishing bullet shells using a magnetic polishing machine, the popularly used polishing media is the stainless steel pins.

These pins polish your brass casings exceptionally well, bypassing through holes and reaching even the most intricate corners.

Stainless steel is an alloy that consists of chromium and iron, commonly known as the Ferritic class of stainless steel.

This kind of stainless steel (Ferritic) is the magnetic kind and polishes exceptionally well when used in a magnetic tumbler.

Other types of stainless steel media are still used to polish parts.

However, for magnetic tumblers, you need to ensure that you’ve bought the magnetic ones and not the non-magnetic ones.
