What You Should Know About Burnishing

The American manufacturing sector is truly enormous. In fact, taken together, all manufacturers contribute around $2.17 trillion to the American economy, and for every $1 spent on it, another $1.40 or so is added back to the economy. Manufacturing also employs around 12.5 million people in various workshops and factories of all sizes, to produce furniture, electronic items, household appliances, cars, and weapons of war. This is truly impressive, but even the biggest factories must not forge the basics. Any factory or workshop owner must regularly contact local suppliers to get everything from roller burnishing and diamond burnishing tools to lathe table parts and machine lubricant oils. Otherwise, a factory would suffer breakdowns or lose productivity. So, what is there to know about diamond burnishing and roller burnishing, and why are lathe tables used?

What is a Burnishing Tool Used For?

Many finished goods are made of metal, or at least have metal components in them, and that metal is going to need some treatment. Partway through the manufacturing process, roller burnishers are used on a piece of metal, a process that uses not heat or chemicals, but pressure to modify the metal’s properties for the final product. A roller burnishing tool has a hard, rounded end that is rubbed all over the metal, which applies pressure intensely but evenly across the surface. Such a process will compress the metal somewhat and smooth it out, which makes it even harder and allows it to bear more weight and pressure while the product is used.

Put another way, roller burnishing toughens the metal, and this process is also aesthetic. This smooth, burnished surface is also shiny and looks attractive, which appeals to buyers and makes a good impression. Many products today are clearly advertised as being burnished, and even jewelry can be burnished. This doesn’t have to be a one-time process, either; a given product may get burnished again if the surface is dull, putted, or otherwise compromised.

Meanwhile, diamond burnishing indeed makes use of the famed hardness of diamonds, to handle burnishing jobs that regular roller burnishing tools cannot. These diamond burnishing tools have small, micro polished tips, and this affects a smaller area than roller burnishers do. This sort of work also has better sliding friction coefficients as compared to roller burnishing, and it’s friendlier for the environment, too, due to a lack of waste products. In particular, diamond burnishing tools are often used to work on small, cramped surfaces inside a metal object that ordinary roller burnishers cannot reach, owing to the small and very hard tip of a diamond burnishing tool. It may be mentioned that even if the diamond tip eventually wears down or becomes damaged, it can be re-ground to restore its performance, and a faulty diamond tip can be removed and easily swapped out for a new one.

Using Lathe Tables

Another vital part of the manufacturing process is the use of lathe tables, which are computer-controlled tables that feature an assembly for holding an item and a rotating grinder surface. This idea is not new; the ancient Egyptians used simple, handheld lathe tools, for example. “Machining” is any process that modifies a material, such as drilling, cutting, or welding wood, plastic, and metal. Doing so often results in upraised imperfections on the material, though, and these are known as burrs (they usually appear right next to the machined site). Burrs are a problem, since at the very least, they look rough and ugly to the eye, and what is more, they can scratch and scrape against other objects and surfaces while the product is in use (causing major damage). Metal burrs in particular may attract static electricity, which can short out local electrical components.

So, the item is placed on a lathe table and fed to the rotating grinder, which simply scrapes off the burrs and leaves a smooth, flawless surface behind. The RPM of that rotating grinder can be adjusted as needed.

Machine Lubricants

Don’t forget machine lube, either, which must be applied regularly to a factory’s machinery. Synthetic and natural oils alike can make machine parts glide more smoothly past each other, so they can move quickly and without harmful friction. Other lubes can prevent machines from overheating or generating static electricity, too.
