Material and Process of Different Knives
A vibratory tumbler is a perfect choice for stainless steel knife polishing. Stainless steel is a very hard material and it requires special attention while polishing.
Once the stainless-steel knives have been forged, it’s time to get rid of the imperfections. The most common and efficient way to do that is to put the batch of knives in a vibratory tumbler with the proper media.
Titanium is a precious metal. It’s heavily used in high-performance applications. Believe it or not, kitchen cutlery like knives can be a performance upgrade too!
Titanium knives are stronger and lightweight. The knives are polished using the vibratory process. Load the tumbler with proper media and the parts.
Bronze is an amazing material that looks good and works precisely as well. These characteristics of bronze make it a great choice for knives.
Knife polishing doesn’t have to be harder than any other polishing. You can use a vibratory tumbler as well as a centrifugal disc finishing machine for bronze knife polishing.
Kitchen knives can be very mysterious items. It can be made of regular stainless steel, carbon steel, or a combination of both. It’s necessary that you know the material before you jump into the polishing.
Depending on the material of your knives, you can use vibratory machines, centrifugal disc finishing machines, or even rotary tumblers.
Tactical knives are another wonder of modern science. The knife polishing process should be a little different when it comes to tactical knives.
If you don’t want a mirror finish on your knives, you can use a rough media and a vibratory tumbler. But if you do want a mirror-like surface, you can use centrifugal disc finishers with a less abrasive media.
In most cases, a chef’s knife would be made of carbon steel. Carbon steel is generally polished in high energy vibratory machines. A closed-lid barrel is preferred.
Load your barrel with the carbon steel knives, media, and water to achieve the results you want. The process can take anywhere from 30 minutes to a few hours.
