Boring as a machining process
An important attribute of bored holes is concentricity. The work usually is held on a face plate or in a chuck when boring is done in a lathe. Holes formed by boring may be bored straight, tapered, or to irregular contours. Boring is essentially internal turning while feeding the drill or machine tool parallel to the axis of the rotation of the workpiece.
Boring on a mini-lathe or a small lathe
In a mini lathe, the idea of boring is simply the art of taking a small hole and making it bigger. A spindle is installed on the mini lathe and it helps in boring. For example, a tube is to be made with inner diameter of perhaps 1 inch and there is no 1 inch wide drill bit. To make such a shape on a mini-lathe, the method known as boring is used. The following picture shows a mini-lathe setup for a boring job.
Uses of boring
Earth boring is very popular and used to do one of the following things:
- Return rock samples through which the machine tool passes.
- Rocks from which material is extracted can be extracted.
- Earth boring can be used to access rocks which can then be measured.
- Boring can also provide access to rock for the purpose of providing
engineering support.
- Boring helps in enlarging an existing hole which may have been the
result of a drill or made by a core in a casting.
- Another important purpose of boring is to make the hole concentric with the rotational axis of the workpiece. This helps in correcting any eccentricity that may result from the drill's having drifted off the center line.
Application fields
Boring is used for a wide variety of applications like as follows:
- Agriculture
- Geology
- Hydrology
- Civil engineering
- Oil and natural gas industries
- Shipyards and Repairers
- Offshore
- Heavy Industrial Sectors
- Petrochemical
- Earthmoving Equipment
- Power Generation etc.
