In today’s manufacturing, it’s rare to find any machines that are completely manpowered. Most factories rely on automation and other computer guided processes to complete large scale productions of consumer goods. Even workshops where products may be made “by hand” still employ a good deal of machines that utilize tool setters and presetters in order to get parts shaped perfectly every time. One such area where these tools are a necessity is for the process of boring.
Most people likely confuse boring and drilling because they sound similar on the surface. Both involve placing a hole into an object, but where they differ is in the methods used for this process. A drill will create a hole “blind,” meaning it’s not yet started, and the size is generally small. However, boring involves either creating a hole blind or already begun, and it will measure larger and potentially deeper than the hole created by a drill. Think of a gun or cannon barrel, for instance; these are created through the boring process.
Which tools are used to bore holes? In most cases, especially with large factory-made creations, boring is done through the use of CNC boring heads. CNC, or computer numerical control, refers to tools that are controlled through computerized presetters, which calculate all of the specifications needed to make a product. Back to the example of boring a gun barrel, a CNC boring head would receive its settings from the computer in order to produce a perfectly created hole each time.
Some boring processes are done through other types of boring tools. Boring machines may be operated by hand, for instance, especially if they are older. However, any metal objects or other heavy materials that require boring will likely be handled by CNC boring heads and tools, especially when creating the same item over and over again in large volumes.
