Having stubborn pieces of metal that have not stayed shiny can be a nuisance. It can be hard to find a great way of polishing everything up in a way that is quick and effective. There is deflashing and barrel polishing, and if you are really inclined, you could do it by hand. But there is also ball burnishing. In essence, this form of polishing is usually something that happens naturally when metal is rubbed continuously against another piece of metal. It can happen with ball bearings. But you can also do it as a way to polish certain pieces of metal as well.
Ball burnishing happens over a period of time when metal is rubbed against each other. It is why there are some pieces that are very shiny if there is a ball and socket fixture. You can use this method on anything really, but it is a more involved process than deflashing or barrel polishing. Basically the process is some sort of heavy, dense steel that is forced against another piece of metal and it will impact that work piece and go over the peaks of its surface profile. This is where it ends up creating a bigger area that will eventually reflect light, thus being shinier.
Ball Burnishing is a process that is highly mechanical and most often you cannot do yourself. You will need some sort of professional who can come in and do it for you. But don’t worry because there are plenty of companies that are able to get this done for you. If you do not know of one in your area, all you have to do is look one up. If you have something that you are not sure if it can be ball burnished, you can just ask them.
Getting all of those old metal pieces shined up and looking like new is always a great feeling. There are some that you do on purpose, for aesthetic reasons, and sometimes you need it done for the function of a certain piece. With the many choices of metal polishing out there for you to choose from, you will find anything that you could possible want. You just want to make sure that the company is well regarded and they will get the pieces done in a timely manner. When you have them all shiny and new in your hands, you will be happy you went to a professional.
