Reaming enlarges or deepens holes in solid materials using specialized tools like lathes, drills, and boring bars. Boring bars are attached to lathes and create more accurate holes with less operator error. They are made of hard materials and can create tapered holes.
Reaming is a mechanical process that makes existing holes in a solid material larger or deeper through the use of specialized tools such as lathes, drills and boring bars. In most cases, boring bars are used in conjunction with a lathe to make holes that are more accurate in terms of positioning and measurement. It can have a number of different diameters to create the necessary mechanical changes to the material being drilled.
A boring bar is usually attached to some sort of lathe or similar machine. A lathe has many uses, but for drilling, it is mostly used for turning bars. Reaming with a boring bar makes a hole that is usually much more accurate than a hole made with a hand drill. The accuracy comes from the fact that the lathe is typically fixed to a surface that is not easily moved, so operator error is greatly reduced.
The boring bar itself is typically made of a very hard material, such as steel or carbide. It is cylindrical like a drill bit, but doesn’t have the same thread pattern. Boring bars can also have a shallow thread that does not progress along their length. This thread pattern can create more vibration through the boring bar than a drill bit, which creates a tighter seal within the material being drilled.
Boring bars are typically longer than drill bits, which creates a larger surface area to initiate vibration. This means that the boring bar will vibrate more than a drill bit. When using boring bars, more attention to detail is required from the machine operator to control these vibrations.
Tapered holes can also be made by using boring bars by varying the rotation of the lathe. The cutting tool needs to make an angle on the axis of rotation to create that taper effect in the hole. Changing the angle adjusts the direction of the boring bar, which can be used to drill tapered holes. Most commonly, boring bars are used in manufacturing and machine tools, but they can also be used for hobby manufacturing and automobile restoration.
