Drilling and Burnishing Materials Today

Manufacturing is one of the leading industries today, and much of it is based on work with metals and diamonds, from assembling items like cars all the way to carving diamonds for jewelry or even diamonds for cutting other materials (taking advantage of diamonds’ hardness). A number of formulas and units of work are used in industries like these to measure how much work is being done and how on a material, and factors like feed rates, burnishing, precision metal finishing, and more should be considered. When feed rates and short lead times are under control, a job can be done efficiently, and more can be produced. Just how big is the manufacturing industry today? What kind of products can be expected from efficient feed rats or burnishing tools and their use?


From cars to personal appliances to computers, manufacturing is enormous in the United States today, and altogether, it adds some $2.17 trillion to the American economy, and this is efficient work; for every $1 spend on manufacturing, another $1.40 is added to the economy. Recent data has shown that 246,363 different firms are found in the manufacturing sector today, and all but 3,626 of them are small firms; meaning, they have under 500 employees. This results in a competitive and widely varied field of work, and this creates a lot of jobs, too. Around 12.5 million manufacturing jobs can be found across the United States today, and this makes up a significant part of the total workforce, about 8.5%. In fact, if the American manufacturing sector somehow became a standalone entity, it would be the world’s eighth largest country in terms of GDP, and all kinds of different tools and materials are used to get all this work done. Workers in car plants, computer factories, and more work with all sorts of materials and will consider the feed rates and burnishing of those materials to make sure a good job is done.

Working with the Materials

What kind of tools might someone find in an American factory today? It will vary based on what is being manufactured, from cars to computers to power tools to home appliances, but there are some general trends when it comes to working with metal. Machining operations today can be sorted into three principle processes: turning, drilling, and milling, and each serve their own purpose. The whole time, metalworking lubricants, coolants, and fluids will be used to make sure a good job is done, and a substantial flow of such liquids will be used in the metal removal process. A rate from four to 20 liters per minute can be expected.

Drilling is needed so that screw and nail holes can be created in metal and similar materials so that fastening jobs can be done with screws, nuts, bolts, and more, and drilling also creates holes where wires, cables, or hoses might be threaded through the material. Other jobs involve cutting smoothly and steadily, to break apart larger sheets or pieces of metal and similar materials into smaller ones, or remove excess material from something being created. This is where feed rates come in. This describes the rate at which a drill, blade, or other tool is going through the material, and in the case of drilling, the formula for such feed rates may be based on how deep the drill goes in a time frame and how many teeth it has, as well as much much material each tooth removes as it works. Drills can often be made of diamonds for tough jobs, seeing how diamond films can be expected to last 12 to 20 times th4e life of carbide in graphite. As a result, diamond drills do not have to be changed very often, and this means consistent tolerance and fewer errors overall.

Burnishing can be an accidental by-product of work, but it can also be intentional when materials or heat are used on a metal’s surface to change its aesthetic, and some consumers, whether business or civilian, may in fact prefer burnished metal if it is done right. Many manufacturers will work hard to burnish metal in a pleasing way at some point in the manufacturing process to make a more saleable product with attractive metal surfaces.
