The Basics of Boring in Manufacturing
The CNC boring process has many industrial applications, such as boring holes in screws, making engine cylinders, and to bore holes into bearings, dowels, and other material that require hollow components.
The subtractive process of boring enlarges pre-drilled or casted holes. Using a single point cutting tool, the process removes material from the interior of a workpiece to improve dimensional accuracy. It is the perfect method for machining holes of different precision grades, diameters, and positional restrictions because of its improved accuracy.
Vertical or horizontal lathes, jig borers, and boring mills, among other machines, are used during CNC bore machining. While different boring tools and machines can be utilized, all boring tools perform the three basic operations. The first is to enlarge holes to the precise and accurate size and finish. Secondly, to straighten pre-drilled or threaded holes to fix casting defects. And third, to produce concentric holes with an external diameter.
The boring process places the machine’s head into the drilled or cast hole and begins to widen the hole by slowly scraping away portions of the inner wall. All boring machines use similar parts. These include the chuck, which is the clamp that securely holds the material in place during boring. Next is the workpiece, or the material you intend to bore a hole into using the boring machine. Finally, there is the boring tool that cuts or portions of the holes, resulting in a larger and more precise hole.
